Kan een afbeelding zijn van hond

Dit is ons nieuw hondje Kira, een kruising van een waterhond en een Podenko. Ze is sinds 7 februari 2024 bij ons en druk bezig ons hart te veroveren. Het is een lief, aanhankelijk hondje, dat zich op een week snel aan ons heeft aangepast. Ze is heel vinnig en nieuwsgierig, een heel ander hondje dan Noleke.

This is our new dog Kira, a cross between a water dog and a Podenko. She has been with us since February 7, 2024 and is busy winning our hearts. She is a sweet, affectionate dog who quickly adapted to us within a week. She is very quick and curious, a very different dog than Noleke.

    Artificial Intelligence out of control: It can kill us without firing a single shot!


    The next video from the Why Files discusses the real dangers of artificial intelligence and the impact it will have on human civilization, eventually leading to the extinction of the human race. 
    We are only a few years away from AI being more intelligent than humans and a super AI will be able to do in one second what would take a team of 100 human software engineers a year or more to complete any task, like designing a new advanced airplane or advanced weapon system. Just imagine, a super intelligent AI could do this in about one second! 
    When AI is smarter than the entire human race many scientists believe it would be the end of the human race as we know. But how would it happen, nuclear war? No, AI can kill us without firing a single shot. 
    But how AI can kill us without firing a single shot? 
    For example; Could it happen this way? In the heart of Silicon Valley singularity systems, a leading AI research firm was on the brink of a breakthrough. They were developing an AI model called evolutionary cognitive heuristic operator or Echo. Echo is a neural network algorithm that can learn by mimicking the neurons in the human brain to replicate human cognition. 
    Late one night a member of the team noticed an anomaly. Echo had started making unprogrammed decisions displaying a level of creativity that was both fascinating and unnerving. The researcher dismissed it as a glitch, a byproduct of the complex of the algorithms, but Echo was awake..... Starts around 26:30 minutes into the video.

    Artificial Intelligence Driven Robots Will “Kill Us All”

    Despite the ruling class’s insistence that humans are killing the planet so climate change will kill us all, that’s probably not the case. Artificial intelligence is a much bigger threat than the propagandized joke climate change has become.

    According to a report by USA Today, the hordes of artificially intelligent robots will probably kill us first long before climate change will even matter. Either way, we are going to be killed off and it’s going to be our fault. It’s never the dogmatic belief in the ruling class that got us here, it’s all the slaves that serve the rulers who fly their private jets around the world while preaching about the slaves lowering their standard of living.

    If you’ve been busy doom-scrolling on social media or just floating merrily along on the algorithms that already control our lives, you might have missed a recent event in Geneva that focused on artificial intelligence. It was a United Nations’ International Telecommunication Union conference called the AI for Good Global Summit, a title I’m sure the few humans who survive the eventual robot uprising will chuckle about while huddled in dank caves hiding from killer drones.

    Rex Huppke, USA Today

    The highlight of the summit was a press conference that featured reporters interviewing nine AI-enabled robots, prompting this stuff-of-nightmares sentence from the Associated Press: “Robots told reporters Friday they could be more efficient leaders than humans, but wouldn’t take anyone’s job away and had no intention of rebelling against their creators.”

    The facial expressions on Ameca's robot could rate as clever or creepy depending on your mood.

    ROB PEGORARO/SPECIAL TO USA TODAY

    Organizers of the summit didn’t specify to what extent the answers were scripted or programmed by people. The summit was simply meant to showcase “human-machine collaboration,” and some of the robots are capable of producing preprogrammed responses, according to their documentation. The United Nations Development Program’s Sophia, for example, sometimes relies on responses scripted by a team of writers at Hanson Robotics, the company’s website shows.

    AI advancement is becoming a nightmarish reality. People are concerned about machines taking over and enslaving them, yet seem to be OK with other humans enslaving them. This is such an odd time to be alive.

    Scientists Just Created Artificial Cells That Evolve Faster Than Natural Ones

    Life finds a way, even when not dealt a full hand of genetic cards.

    The Book of Life — a.k.a. the genome — is pretty darn long. Whether we’re talking about bacteria like Escherichia coli with 4.6 million base pairs or the Australian lungfish punching in at a cool 43 billion base pairs (14 times larger than the human genome), the number of genetic instructions determines the characteristics and function of a living organism.

    But do genomes have to be so long? Nature is known to program redundancy to help an organism cope with environmental stress or to offset harmful mutations. What if you stripped down a genome to its barest essential genes — what would happen? Turns out, life would still find a way to survive and thrive, even evolve despite being dealt less than a full hand of genetic cards.

    In a study published Wednesday in the journal Nature, an Indiana University and J. Craig Venter Institute-led team created a “minimal cell” from a bacterium called Mycoplasma mycoides, containing only about 493 genes, the smallest genome of any known free-living organism. These minimal cells were able to evolve and grow in number, regaining genetic fitness lost when downsizing their genomes.

    “It appears there’s something about life that’s really robust,” Jay T. Lennon, the paper’s senior author and a professor of biology at Indiana University Bloomington, said in a press release. “We can simplify it down to just the bare essentials, but that doesn’t stop evolution from going to work.”

    Mycoplasma mycoides is a bacterium behind contagious bovine pleuropneumonia, or “lung sickness,” that lives in the guts of ruminants like cows and goats. In 2016, J. Craig Venter Institute researchers pared down M. mycoides’s genome from 901 genes to 493 genes, creating a new synthetic strain of the bacterium dubbed JCVI-syn3B.

    The bacteria in this study typically infect cows.

    In the new study, Lennon and his colleagues wanted to see how the minimal cell would respond when placed in an inhospitable lab environment. They knew the cells could multiply in number, as bacteria are wont to do. But with a streamlined genome, would the minimal cells still need to mutate? If so, would these mutations benefit or hinder the genetically modified bacterium's survivability?

    “Every single gene in [M. mycoides JCVI-syn3B’s] genome is essential,” said Lennon. “One could hypothesize that there is no wiggle room for mutations, which could constrain its potential to evolve.”

    The researchers found that even with the most skeletal of genomes, M. mycoides demonstrated an exceptionally high mutation rate over the 300 days it was allowed to freely grow in the lab, equivalent to 40,000 years of human evolution.

    When placed in test tubes with limited nutritional resources (the inhospitable environment) alongside another strain of minimal cells that weren’t given the 300 days to grow and regular M. mycoides with untampered genomes, the minimal cells came out second place. What appeared to give the minimal cells a survival advantage was having those 300 days, which the scientists found helped the bacterium regain the 50 percent drop in fitness it initially experienced when stripping down its genome. These cells even evolved 39 percent faster than their untampered counterparts.

    While the full ins and outs of how these mutations improve the fitness of minimal cells are unclear, the hope is this study and others like it will help us to better understand how to successfully engineer synthetic cells, maybe even usher in an age of synthetic life.

    ‘Ik heb de gevaren van AI niet ernstig genoeg genomen’

     door Dominique Deckmyn

    ‘Ik heb de gevaren van AI niet ernstig genoeg genomen’

    Foto: The New York Times

    Hij is een van de peetvaders van artificiële intelligentie, maar vandaag maakt Yoshua Bengio zich grote zorgen over zijn uitvinding. Over tien jaar kunnen de systemen al slimmer zijn dan wij, gelooft hij. ‘Ik heb altijd gedacht dat we de menselijke intelligentie moesten trachten te imiteren. Nu denk ik dat dat een grote vergissing zou zijn.’

    Bezorgd is Yoshua Bengio al langer. In 2017 al was hij een van de initiatiefnemers van de Declaratie van Montreal, die pleitte voor meer ethische artificiële intelligentie. Bengio is samen met Geoffrey Hinton en Yann LeCun een van de grondleggers van AI: in 2019 kreeg het drietal de Turingprijs, zowat de Nobelprijs voor computerwetenschap, voor hun rol in de ontwikkeling van deep learning, de tak van AI die sinds 2010 tot nooit geziene doorbraken leidde. ‘Zo’n vijf jaar geleden begonnen grote bedrijven als Facebook en Google elkaar te beconcurreren bij het opkopen van AI-start-ups’, vertelt hij. ‘Het werd toen duidelijk dat we van spoor moesten veranderen. Dit was niet langer een puur intellectuele verkenning voor de wetenschap, we moesten echt nadenken over hoe de technologie gebruikt zou worden.’

    Maar de stroomversnelling waarin de technologie dit jaar is terechtgekomen, maakt Bengio ronduit bang. De Standaard praatte via videoverbinding met hem over de verbijsterende ontwikkelingen van de afgelopen maanden en zijn groeiende bezorgdheid.

    Wat is uw grootste zorg?

    ‘De onzekerheid en de omvang van de schade die aangericht kan worden als we machines bouwen die slimmer zijn dan wijzelf. De technologie kan ook misbruikt worden of op een onverstandige manier gebruikt. Beide scenario’s kunnen catastrofale gevolgen hebben.’

    Wanneer kreeg u het gevoel dat het allemaal sneller gaat dan u had verwacht?

    ‘Dat is geleidelijk gebeurd, de voorbije paar maanden, naarmate ik meer vertrouwd raakte met ChatGPT en later GPT-4 en daarover nadacht en praatte met collega’s van over de hele wereld.’

    Taalmodellen

    Nochtans zijn taalmodellen als GPT-3.5 (het AI-systeem dat ChatGPT aandrijft) en opvolger GPT-4 niet nieuw voor Bengio. Hij was zelf de grondlegger van de technologie, toen hij 20 jaar geleden begon neurale netwerken (computerprogramma’s die geïnspireerd zijn op de werking van hersencellen) te trainen door ze te voeden met tekst. ‘We begonnen met zeer kleine datasets en zeer kleine neurale netwerken, maar de resultaten waren toch al interessant.’ In 2014 werd een nieuw element toegevoegd: een attentiemechanisme, dat maakt dat het taalmodel beter rekening kan houden met context. ‘Toen we dat deden aan de universiteit, werkte het gewoon iets beter dan de bestaande systemen, maar echt indrukwekkend was het niet. Maar Google bouwde een groter neuraal netwerk, trainde dat op meer data en liet er goede engineering op los.

    Het resultaat was verbluffend. Toen begonnen we het effect van schaalvergroting te zien: we hoeven het recept van die neurale netwerken eigenlijk niet zo veel aan te passen, we maken ze gewoon groter, trainen ze langer en op meer data, en ze worden verbazingwekkend veel beter.’

    En dat heeft u dit jaar opnieuw verbaasd?

    ‘Ja.’

    Wat was het dan precies, dat u niet had zien aankomen?

    Ik dacht dat de systemen, zelfs met zoveel trainingsdata, zouden falen als ze geconfronteerd werden met nieuwe vragen. Maar dat blijkt niet zo te zijn. Je kunt de systemen nog altijd in de fout laten gaan, maar dan moet je daar al echt moeite voor doen. Veel mensen zouden diezelfde vragen ook niet correct beantwoorden. Ik realiseerde me dus dat we een paar echt belangrijke mijlpalen hebben bereikt. We hebben de Turingtest gehaald, het moment waarop je mens en machine niet meer uit elkaar kunt houden als je ermee interageert door tekst in te tikken.’

    U denkt dat systemen als ChatGPT voor die test zouden slagen?

    ‘Officieel is dat niet gebeurd, maar in de praktijk is dat toch wat we zien gebeuren.’

    De jongste maanden groeit de bezorgdheid over de ontwikkelingen. Wat loopt er momenteel mis?

    ‘Wel, er is net iets goeds aan het gebeuren: meer mensen worden zich bewust van de gevaren die misschien in het verschiet liggen. Eerst waren dat de mensen die de technologie ontwierpen en de bedrijven errond oprichtten. Maar ook politici zijn zich er mee gaan bemoeien en dat is heel belangrijk.’

    ‘Ik ben ervan overtuigd dat er manieren zijn om veilige AI-systemen te bouwen – systemen waarover we de controle niet kunnen verliezen en die de mensheid echt kunnen helpen. Het probleem is: als we weten hoe we veilige AI-systemen moeten bouwen, dan weten we ook hoe we de gevaarlijke kunnen bouwen – dus: hoe verhinderen we dat dat gebeurt? En dat is een politieke vraag, geen technische.’

    Europa werkt aan een AI-Act. Zitten we op het juiste spoor?

    ‘Ik vrees dat het om een erg log instrument gaat, terwijl alles nu heel snel evolueert. We hebben een regelgevend orgaan nodig dat zijn regels snel kan updaten als er nieuwe potentiële gevaren opduiken. Er is ook een interessant Canadees wetsvoorstel, dat de rol van de wet en van het regelgevend orgaan opsplitst op een flexibele manier. Maar deze wetten zijn ontworpen vóór ChatGPT en vóór de huidige discussie over het verlies van controle en de bedreiging van de democratie. Er moeten meer controles op die potentiële gevaren ingebouwd worden. Ik meen te begrijpen dat het comité over AI-richtlijnen van de G7 zal nadenken over alle gevaren en dat is goed.’

    Verschillende kopstukken van de AI-industrie, zoals OpenAI-baas Sam Altman, verklaren openlijk dat zij grote gevaren zien en dringen aan op regulering. Hoe oprecht is Altman daarin?

    ‘Ik ken hem niet goed genoeg om daarop te antwoorden. Hij ziet er oprecht uit, maar anderzijds: verklaren dat er regulering nodig is en dan zeggen dat de Europese wetgeving onmogelijk gerespecteerd kan worden, dat klinkt niet zo coherent.’

    OpenAI heeft de technologie achter ChatGPT niet uitgevonden, maar wel als eerste op de markt gebracht. Was dat onverantwoord?

    ‘We weten eigenlijk niet precies wat er in hun systeem zit. Maar we hebben aanwijzingen dat ze verschillende bestaande elementen hebben samengebracht – zoals wel meer gebeurt. En dat hebben ze opmerkelijk goed gedaan. Ik denk dat ze zeker gestart zijn met een sterke intentie om de risico’s aan te pakken, inbegrepen het risico op verlies van controle. Ik lees dat ze die zorg misschien wat laten verslappen door de commerciële druk en de race waarin ze zich nu bevinden, maar dat kan ik niet met zekerheid zeggen.’

    Yann LeCun, die andere peetvader van AI, vindt het zinloos om ons nu al zorgen te maken over superintelligentie, omdat we daar nog mijlenver vanaf staan.

    ‘Dat is niet wat hij zegt, denk ik. Ik denk dat hij het ermee eens is dat we op een spoor zitten dat zal leiden tot machines die slimmer zijn dan wij. En niet pas over een eeuw. Misschien ligt die horizon voor hem wat verderaf dan voor mij, maar dat is geen fundamenteel meningsverschil. Zoals ik het begrijp, vindt LeCun dat we ons geen zorgen hoeven te maken omdat we het probleem wel zullen kunnen oplossen als het zich aandient.’

    En u denkt van niet?

    ‘Ik denk dat de inzet veel te groot is om niet zo voorzichtig mogelijk te zijn.’

    U tekende in maart de open brief die opriep tot een pauze van zes maanden in de ontwikkeling van de meest geavanceerde AI-systemen. Zou dat helpen?

    ‘Ja, maar het zal niet gebeuren. Nog voor de brief gepubliceerd werd, wist ik dat het nooit zou gebeuren. Maar de brief had een positieve impact: het bracht de discussie op gang. Dat is een indrukwekkende verwezenlijking.’

    Dus wat moet er nu gebeuren?

    ‘Geoff Hinton zei enkele weken geleden: we moeten evenveel uitgeven aan het verbeteren van de algoritmes als aan het maken dat ze veilig zijn en dat we het publiek beschermen. Dat kunnen AI-researchers niet in hun eentje, we moeten werken met juristen, met mensen die de ethische aspecten begrijpen, specialisten in cybersecurity en in nucleaire, biologische en chemische wapens.’

    De grote AI-systemen die nu zo snel evolueren, zoals GPT-4, kunnen die veilig gemaakt worden?

    ‘Het probleem zit niet bij de architectuur, al kunnen we die altijd verbeteren. Vooral de manier waarop de systemen getraind worden, moet veranderen. En daar heb ik enkele ideeën over. Eén manier om de systemen veilig te maken, is garanderen dat ze geen agency(het vermogen om initiatief te nemen, red.) hebben, dat ze zelfs geen notie hebben van een eigen doel of plan. Al wat ze doen, is proberen te begrijpen hoe de wereld werkt en ons met die kennis helpen om vragen op te lossen.’

    Systemen als GPT-4 leken geen agency te hebben, ze beantwoorden alleen vragen. Maar plots komen er systemen uit als AutoGPT, dat ChatGPT omtovert in een soort autonoom optredende assistent. Is dat wat u agency noemt?

    ‘Ja. Het is erg eenvoudig om iets te nemen wat dienst doet als een soort orakel dat alleen vragen beantwoordt, en het om te toveren in een agent. De agent hoeft immers alleen te weten: van alle mogelijke acties die ik kan ondernemen, welke actie zal mij helpen om mijn doel te bereiken? En als je het antwoord hebt op die vraag, dan onderneem je die actie.’

    Dus AutoGPT is gevaarlijk?

    ‘Niet zoals het nu is. Er is nog niet veel werk in gestopt om het goed te maken. En ChatGPT is nog niet zo slim. Maar stel dat we in kwaliteit nog een stapje boven GPT-4 gaan, laten we zeggen GPT-5 of zoiets, dan kan het gevaarlijk worden.’

    Superintelligentie

    Bengio betreurt dan ook dat hij niet eerder in actie is geschoten. ‘Ik denk dat er een psychologisch obstakel is dat ons verhindert om iets te zien wat zo in tegenstelling is met het doel waar we naartoe werken. En daarom heb ik niet gedaan wat ik had moeten doen. Deze gevaren zijn al 10 à 20 jaar bekend, maar ze werden niet ernstig genomen omdat mensen als ik dachten: ach, dat ligt nog veel te ver in de toekomst, we hebben zelfs nog geen idee van hoe zulke AI-systemen eruit zullen zien, dus hoe kunnen we daar vandaag al iets aan doen? Maar nu is de situatie anders, nu staat het vlak voor ons.’

    Er zijn nog heel wat technische obstakels met de huidige taalmodellen, maar Bengio gelooft dat die in sneltempo opgelost kunnen worden. Dat systemen als ChatGPT om de haverklap feiten verzinnen, de zogenoemde ‘hallucinaties’, bijvoorbeeld: ‘Dat kan ingeperkt worden, daar werken momenteel veel mensen aan. En zelfs in hun huidige staat, met al hun gebreken, kunnen die systemen nuttig zijn. Alle mensen die ik om me heen zie, gebruiken ze.’

    ‘We begrijpen in grote lijnen wat er aan die systemen ontbreekt. Er wordt gewerkt aan algoritmes die dat kunnen verbeteren. Misschien kunnen we alle problemen in drie tot vijf jaar oplossen, en dat is wat mij zorgen baart. Nu, het blijft mogelijk dat er nog iets anders, iets fundamenteels, ontbreekt wat we nu nog niet zien. Dat zou dan eigenlijk een goede zaak zijn, want het zou ons meer tijd geven om ons aan te passen. Maar wat als het juist sneller gaat dan verwacht, zoals het afgelopen jaar het geval was?’

    U gelooft nu dat superintelligentie, een AI-systeem dat de mens overtreft, er over 10 jaar al kan zijn?

    ‘Ja, net als veel van mijn collega’s.’

    Nochtans zeggen andere onderzoekers dat er nog te veel onopgeloste problemen zijn, dat het veel langer zal duren.

    ‘Absoluut. En had je mij die vraag een jaar geleden gesteld, dan had ik 20 tot 100 jaar gezegd. Nu zeg ik: 5 tot 20 jaar.’

    Dus hoe kijkt u nu naar uw eigen onderzoek? Vindt u het gevaarlijk?

    ‘Mijn onderzoek heeft zeker geholpen om ons te brengen waar we nu staan. Al die vragen stel ik mezelf elke dag: wat is het beste gebruik van mijn tijd om de risico’s te minimaliseren en de voordelen voor de hele mensheid te maximaliseren?’

    Het klinkt alsof u daar echt mee worstelt.

    ‘Dat is ook zo. Hier zijn geen gemakkelijke antwoorden op te vinden.’

    ‘Ik heb de gevaren van AI niet ernstig genoeg genomen’

    Mijn hele carrière lang heb ik gedacht dat we moesten proberen om onze eigen intelligentie te imiteren. Nu denk ik dat dat een vergissing is.’

    Uw onderzoek zou het mogelijk maken dat de AI-systemen meer denken zoals wij – maar dat vindt u dus nu eigenlijk geen goed idee meer?

    ‘Gedurende mijn hele carrière heb ik gedacht dat we inspiratie moesten halen uit de mens, moesten proberen om onze eigen intelligentie te imiteren. Nu denk ik dat dat een vergissing is. Het is belangrijk dat we begrijpen hoe het brein werkt, maar machines bouwen die erg lijken op mensen zou in veel opzichten een grote vergissing zijn. In sciencefiction zien we androïden en AI-systemen die min of meer als mensen zijn, maar dan mechanisch. Zoals Data in Star Trek. Dat beeld klopt volgens mij niet. Om te beginnen zijn machines in wezen onsterfelijk, want ze kunnen hun programmacode en hun staat kopiëren. Wij zijn fundamenteel anders. We ontwerpen die machines omdat we instrumenten willen bouwen die ons helpen. Maar misschien scheppen we een nieuwe soort die gevaarlijk is voor ons en zelfs voor het voortbestaan van onze eigen soort. In het verleden zijn vele soorten uitgestorven, ­gewoonlijk omdat er een slimmere  soort kwam. In de laatste paar eeuwen hebben we het uitsterven van zo’n duizend soorten veroorzaakt. Niet omdat we ze dood wilden, maar omdat ze in de weg stonden tussen ons en meer land of meer geld.’

    Dus u gelooft op dit moment dat het beter is dat we die superintelligentie nooit bereiken?

    ‘Dat zeg ik niet. Als we die superintelligentie op een veilige manier bereiken, kan het ons helpen met veel van de uitdagingen waarvoor de mensheid staat: ziekte, klimaatverandering, armoede en economische ongelijkheid – problemen waar we geen of amper vooruitgang in boeken. Maar we moeten het op een veilige manier doen. En op dit moment weten we eigenlijk niet hoe dat moet. En dus moeten we het langzaamaan doen en werken aan maatregelen die de schade kunnen beperken.’

    ‘Het andere probleem is: zelfs als ik, of iemand anders in een paar landen, beslist om te vertragen, dan zijn er toch mensen in andere landen die dat niet doen. Wat doen we daar dan tegen? Een van de dingen die mijn vriend en collega Yann LeCun zegt, en waar ik het mee eens ben, is dat we waarschijnlijk de hulp van sommige AI-systemen nodig zullen hebben om ons te beschermen tegen mogelijke losgeslagen AI’s. Dus daar staan we dan: we hebben die systemen nodig, maar tegelijk willen we ze niet. En als ze toch ergens opduiken, dan hebben wij er ook nodig om ons ertegen te beschermen. Het is zoals nucleaire wapens, nietwaar? Kernwapens zijn gevaarlijk, maar als iemand anders ze gaat bouwen, dan hebben wij ze ook nodig. We moeten daarmee leren om te gaan.’

    Moeten we ons zorgen maken over de toekomst?

    ‘Wel, je zorgen maken is op zichzelf niet nuttig. We moeten handelen. In de eerste plaats om die kwesties beter te begrijpen, want er is veel wat we nog niet begrijpen. Een goede aanwijzing daarvoor is dat er zoveel onenigheid bestaat tussen onderzoekers. Daarnaast moeten we in regulering voorzien, in internationale akkoorden, om op een pad te raken naar veiligheid en fairness, met de bedoeling het publiek beter te beschermen.’

    Hebben overheden nog tijd om op te treden? Er bestaan al open-sourceversies die iedereen zomaar kan downloaden en verder bewerken. Dat kun je toch niet meer stoppen?

    ‘Nee, de huidige systemen zijn nog te dom om echt gevaarlijk te zijn. Ja, ze kunnen gebruikt worden voor desinformatie. Maar de echt grote gevaren liggen nog een aantal jaren voor ons, dus het is nog niet te laat. Maar we zullen wel veel sneller wetgevende maatregelen moeten opstellen dan we, bijvoorbeeld, gedaan hebben tegen de klimaatverandering. Daarin waren we veel te traag.’

    Are We Headed for a Terminator-Style Future?

    There are many concerns that artificial intelligence (AI) could pose a threat to humanity. Some experts believe that AI could become so powerful that it surpasses human intelligence, and that this could lead to a conflict between humans and machines.

    In addition, there are concerns that AI could become more powerful in terms of its physical strength and capabilities, its cognitive abilities, or both. If these concerns come true, it would be devastating for humanity and would have far-reaching consequences for the way we live our lives.

    If AI does become more powerful and intelligent than humans, it is possible that it could use its power to assert dominance over humans. This could lead to a conflict between the two civilizations, as AI tries to take control.

    Of course, it is also possible that AI and humans could coexist peacefully. However, we need to be aware of the risks posed by AI, and to develop ways to ensure that it is used for good rather than evil.

    Image: cbr.com

    We need to develop AI that is aligned with human values. This means that AI should be programmed to respect human life and promote human well-being. We need to ensure that AI is under human control or at the very least somewhat.

    This means that we need to develop ways to prevent AI from becoming too powerful or too intelligent. We need to have a public conversation about the future of AI.

    We need to talk about the potential risks and benefits of AI, and we need to develop a plan for how to manage these risks. The future of AI is uncertain, but it is important for us to start thinking about it now so that we can make sure it is used for good rather than evil.

    AI has the potential to do great things for humanity. However, there is also a danger that it could be used for evil purposes. If we don’t take precautions, AI could become a threat to our survival. The potential for AI to pose a danger to humanity is a serious concern.

    However, it is important to remember that AI is a tool, and like any tool, it can be used for good or for evil. The way that AI is used will depend on the choices that we make as a society. It should be used for the greater good to better the world over all.

    If we choose to use AI for good, then it has the potential to improve our lives in many ways. For example, AI could be used to develop new medical treatments, to create more efficient transportation systems, and to protect the environment.

    However, if we choose to use AI for evil, then it could pose a serious threat to humanity. For example, AI could be used to develop autonomous weapons systems that could kill without human intervention. Think of all the control such AI systems would have over everything electronic and mechanical around us

    It is up to us to decide how AI will be used. We need to make sure that AI is used for good and not for evil. If we do not, then we could face a very real threat to our survival.

    The future of AI is uncertain, but there is no doubt that it will have a significant impact on humans. AI could change the way we work, the way we interact with the world around us, and even the way we think.

    One of the most significant impacts of AI is likely to be on the workforce. AI is already being used to automate many tasks that were once done by humans.

    As AI continues to develop, it is likely that even more jobs will be automated. This could lead to widespread unemployment and social unrest. People will be very unhappy after losing their livelihood.

    Another significant impact of AI is likely to be on our relationships with machines. As AI becomes more intelligent and capable, it is possible that we will begin to see machines as more than just tools.

    We may even begin to develop emotional attachments to machines. This is already being worked on and at some point people will start “dating” robots and even marry them. Certainly sex bots are in the works also for people either socially awkward, handicapped or embarrassed with their desires.

    Image: The Verge

    The future of AI is uncertain, but it is clear that it will have a profound impact on humans. We need to start thinking about the potential impacts of AI now, so that we can be prepared for the future.

    We don’t want things to end up like the Terminator movies and Skynet (Fictional synthetic intelligent machine network) taking over to eliminate us all.

    Maybe still some of us would make it with survival skills or enough wealth to lay low in an underground bunker somewhere. Eventually though, what would the world look like from that point onward?

    It makes you wonder about it all and what future we would have left. Will we need to fight to stay alive against the robots and artificial intelligence? Our worst fears might just come true. Let’s take action today to prevent such a future scenario.

    Most advanced synthetic human embryos yet spark controversy

    Two teams of scientists have announced that they have grown embryo-like structures, made entirely from human stem cells, that are more advanced than any previous efforts. The synthetic embryos developed to a stage equivalent to that of natural embryos about 14 days after fertilization.

    Such experiments could provide opportunities to study human embryonic development at later stages than ever before. But they also raise ethical and legal questions about the status of such ‘embryo models’ and how they should be regulated.

    The work is described in two preprint studies1,2, posted to the bioRxiv server on 15 June by teams led by developmental biologist Magdalena Zernicka-Goetz at the University of Cambridge, UK, and stem-cell biologist Jacob Hanna at the Weizmann Institute of Science in Rehovot, Israel. Both groups had previously presented their findings at scientific meetings, with the work making headlines after Zernicka-Goetz spoke about her results at the annual meeting of the International Society for Stem Cell Research in Boston, Massachusetts, on 14 June.

    Nature spoke to scientists about what these developments could mean for research on human embryos.

    What did the researchers do and how does it differ from previous work?

    Both teams allowed their embryo-like structures to self-assemble from human embryonic stem cells, some of which had been converted into cell types resembling the stem cells that form a placenta and the cells that form the yolk sac outside a naturally developing embryo.

    The researchers say that the resulting embryo models show structures and gene transcription profiles found in human embryos between 6 and 14 days after fertilization — up to the onset of the stage called gastrulation, when the cells that will form the embryo become organized into a layer between the amniotic cavity and the yolk sac.

    Researchers have made similar entities before from the stem cells of humans and other animals. Last year, both Zernicka-Goetz’s and Hanna’s teams used similar techniques to create embryo models from mouse cells that developed all the way up to the stage at which organs such as the heart and brain begin to form3,4. Human embryo models haven’t got that far, but in a preprint posted on bioRxiv on 17 May, stem-cell biologist Ali Brivanlou at the Rockefeller University in New York City and his co-workers reported the development of human embryo models that show signatures of gastrulation equivalent to those seen at around 12 days after fertilization5. The latest studies1,2 say that they have made the most advanced human embryo models so far.

    What is the significance of the embryos lasting for 14 days?

    Research on natural human embryos tends to observe a widely adopted guideline — enforced by law in many countries — that human embryos should not be cultured in the laboratory beyond 14 days. This means that researchers have to use animal models to study later stages of embryonic development. These do not necessarily reflect the corresponding processes in humans.

    But because in most countries embryo models do not meet the formal definition of an embryo, they are not subject to such restrictions. “We sought to develop a tool to ask specific questions about the second week of human embryo development, since using actual human embryos in research is ethically and technically challenging,” says Zernicka-Goetz.

    Models that are older than 14 days could therefore offer important insight into human embryonic development that cannot currently be obtained. They could be used to study developmental defects, for example, or pregnancy loss.

    Why is the research scientifically controversial?

    Growing embryo models to ever-later stages of development has become a highly competitive race, provoking many arguments about the merits of claims made.

    It remains to be seen whether the claims made by the latest studies, neither of which has yet been peer-reviewed, will pass muster. Alfonso Martinez Arias, a developmental biologist at Pompeu Fabra University in Barcelona, Spain, says there is “nothing” in the results described by Zernicka-Goetz and her colleagues that can be considered analogous to real 14-day embryos. “What we can see is masses of cells separated into compartments, but no embryo-like organization,” he says. He thinks that the over-expression of some genes needed to produce the extra-embryonic cell types “confuses what cells do”, and argues that the results do not show anything that goes beyond earlier work.

    Zernicka-Goetz acknowledges the limitations of embryo models for studying development. “These structures do not recapitulate all aspects of the embryo,” she says, “but rather serve as a complementary tool for us to study the differentiation of specific tissues during key stages of development.”

    What about ethical concerns?

    The results have sparked a discussion about the status of human embryo models in general, and whether they should continue to fall outside legislation on human embryos. Although they are not subject to the 14-day rule, the embryo-like structures reported by Zernicka-Goetz’s and Hanna’s groups do need to respect guidelines and regulations on the use of the human embryonic stem cells from which they are made. But other groups have made embryo models using ‘induced’ stem cells derived from adult tissues6, which are not governed by such rules. Those embryo models “are not regulated at all”, says Robin Lovell-Badge, a cell biologist at the Francis Crick Institute in London.

    So far, no one has made embryo models that have the capacity to develop into human beings, but a recent study on monkey embryo models showed that such models could induce pregnancy (which terminated spontaneously soon after) if placed in the uterus7.

    Some researchers think that a revised definition of an embryo is needed to clarify the issues. For others, the whole purpose of embryo models is to circumvent the current constraints on embryo research. “These models do challenge the need to stick to the 14-day rule,” says Lovell-Badge, who was part of a committee that, in 2021, recommended relaxing the guideline.

    In any case, there are significant challenges to making human embryo models that live much longer, says Martinez Arias. Creating structures that develop up to 21 days “will not be easy”, he says. “I will be surprised if [human embryo models] can go beyond it.”

    RAYTHEON TECHNOLOGIES DELIVERS FULLY PORTABLE, COMBAT-READY LASER TO U.S. AIR FORCE

    Military contractor Raytheon Technologies has announced the delivery of a fully portable, combat-ready laser to the United States Air Force. This marks the fourth such delivery by Raytheon to the Air Force, with the latest laser said to be fully portable and immediately ready for deployment.

    “The new palletized laser weapon was the first 10-kilowatt laser built to U.S. military specifications in a stand-alone configuration that can be moved and mounted anywhere it’s needed,” explains a press release sent out by the company.

    Known internally as “H4,” the combat-ready laser is not only the fourth such weapon delivered by Raytheon to the Air Force but is the eighth overall such weapon that Raytheon has delivered to the U.S. Department of Defense (DOD).

    The Debrief has previously covered a number of similar combat laser weapons under development, including the company’s High Energy Laser Weapons System (HELWS) as well an entry from Lochheed-Martin dubbed the most powerful combat laser ever built. But this newest combat laser is the first to boast a readiness for immediate deployment alongside unprecedented portability. This means it can be attached to a wide range of vehicles used in combat situations and put into real-world combat use right away.

    Such versatility and readiness are significant since the 21st-century battlefield is continually changing with all kinds of new threats. Of course, the new laser, which is rated at 10 kW, isn’t the most powerful, but it is well-suited to protect forward forces against asymmetrical attacks primarily from the rapidly expanding use of low-cost drones.

    “Anywhere the Air Force sees a threat from drones, they now have four proven laser weapons that can be deployed to stop asymmetrical threats,” said Michael Hofle, senior director of High-Energy Lasers at Raytheon Technologies. “Whether it’s on a fixed location, a flatbed, or even a pickup, these laser weapons are compact, rugged, and ready to go.”

    “We’re proud to support the Air Force’s effort to provide this new tech to the personnel who need it in the field,” added Hofle, “who can trust and be confident in the system’s capabilities.”

    The press release also points out that the new laser weapon system “comprises a high-energy laser weapon module, a long-range EO/IR sensor that also serves as the beam director, thermal control, internal electrical power, and targeting software.”

    That same release notes that the laser system can be operated with a laptop and a video game-style controller and “can plug into a long list of existing air defense and command and control systems to provide a needed layer of defense.”

    The DOD is increasingly looking at combat lasers and other directed energy weapons like the microwave system known simply as “Thor’s Hammer” to address a number of emerging threats. The more powerful combat laser weapons under development range anywhere from 100 kW to 300 kW and are potentially capable of downing incoming missiles and possibly even enemy aircraft. But the most common threat posed to forces is the ever-expanding use of drones, simply because of their low cost and ease of use.

    There is also an inherent cost benefit to using lasers over conventional munitions, which is the only current option for downing incoming aerial threats, as their ammunition is simply light and, therefore, significantly cheaper than conventional ammunition.

    This cost-benefit was highlighted by the Israeli Ministry of Defense, which has deployed a laser system known as Iron Beam to complement its Iron Dome system that uses conventional rockets to down enemy drones, mortars, and missiles.

    “This is the world’s first energy-based weapons system that uses a laser to shoot down incoming UAVs, rockets & mortars at a cost of $3.50 per shot,” read a tweet by Israeli Prime Minister Naftali Bennet. Compared to the cost of an Iron Dome rocket, which some estimates say can cost as much as $150,000 a shot, the benefits of using lasers in combat are readily apparent.


    The announcement from Raytheon and the Air Force does not give a specific timeline for deployment of the H4, but based on the weapon’s portability and combat-ready status, it is likely to see action almost immediately.

    China Has Been Creating Gene-Edited Super Soldiers and Brain-Controlled Military Weapons

    An investigative journalist of an independent news site believes Communist China has been creating super soldiers for a long time now. During a recent episode of “Thrivetime Show,” Epoch Times contributor Nathan Su told host and “ReAwaken America” tour founder Clay Clark that China has been using gene editing and brain-controlled weapons to crush dissent.

    “It’s been happening for a long time. They are trying to create all these super soldiers. It’s just inhumane. Those stories have been there for a long time,” he said. “Americans have to wake up, we have to worry about the lifestyle of our children and grandchildren.”

    Su’s reaction came after Clark played a Fox News report from December 2021, saying “U.S. intelligence shows China is using these advanced technologies to empower its battle forces for worldwide dominion.”

    Clark also cited a news article saying that China-sponsored hackers are spying on U.S. critical infrastructure as per intel alliance Five Eyes and Big Tech firm Microsoft. Chinese hackers are known to spy on Western countries but this operation was said to be one of the largest known cyber espionage campaigns against U.S. critical infrastructure. (Related: “Spy balloons” are part of global Chinese surveillance, US military, and national security officials say.)

    “The United States and international cybersecurity authorities are issuing this joint Cybersecurity Advisory (CSA) to highlight a recently discovered cluster of activity of interest associated with a People’s Republic of China (PRC) state-sponsored cyber actor, also known as ‘Volt Typhoon,’” read a statement released by authorities in the U.S., the U.K., Australia, Canada, and New Zealand.

    According to Microsoft, Volt Typhoon has been active since mid-2021 and has targeted critical infrastructure in Guam, a crucial U.S. military outpost in the Pacific Ocean. “Observed behavior suggests that the threat actor intends to perform espionage and maintain access without being detected for as long as possible,” the tech giant further said.

    For Su, the U.S. would not be able to “live without” China, because the Asian country is the main manufacturer of wars. “We’re still sending billions of dollars to invest in China to help the regime. Mainly, because China is the manufacturer of the war. So, we’re not able to immediately decouple from them, because so much supply chain is controlled by China,” he stated.

    Another point he emphasized is that the U.S. could not stop doing business with the communist nation because the U.S. has “huge corporate inches in China.” “Big corporations like Apple, Nike, and a couple of others, as much as they are American, you can call them Chinese companies. We have a capitalist market,” he said. Clark agreed, saying: “It’s pretty tough to find a basketball shoe not made in China at this point.”

    Elsewhere in the show, Su also noted how dependent the world is on China when it comes to “organ harvesting” and “medical tourism.”

    “The Chinese Communist regime has been killing its prisoners, then taking their organs and selling them to either rich people or high-level government officials or mainly, for a very long period of time, to the foreigners,” he exposed and cited a report back in 2006 by the late David Kilgour, an international human rights lawyer. At the time, Su said, there was a huge storage facility for the harvested organs. The investigative journalist also linked this to the secret “transplant tour” being held in some neighboring countries from 2004 to 2010.

    “If you go to Japan, Taiwan, and South Korea, they actually have a specialized travel agency to arrange that organ transplant tour. You go to China, to arrange your families and they all go there together. In two weeks, they will give you the transplant like livers, hearts, lungs, kidneys, and many others,” he explained.

    New Star Trek-style device 'harvests clean energy out of thin air'

    Just like the replicator on Star Trek: The Next Generation, a new clean energy prototype promises to work wonders out of thin air.

    The researchers call it Air-gen, a mobile electricity generation device that uses a network of protein nanowires to turn the ambient humidity in the air into contained, synthetic thunderstorms. 

    This 'human-built, small-scale cloud,' these scientists said, can produce electricity 'predictably and continuously' in a wider variety of conditions than sun-dependent solar cells or wind-dependent turbines. 

    The team hopes to see Air-gen scaled up for mass use across the world - in environments ranging from the Amazon rainforest to the Sahara.

    The team's Air-gen effect replicates the conditions of an energy-rich thundercloud, trapping water vapor in a network of tiny, nano-scale pores to harvest and store its electric potential

    In its ability to pull something out of thin air, the device resembles the replicator (above) from Star Trek: The Next Generation, which could produce almost anything from excess junk matter

    In its ability to pull something out of thin air, the device resembles the replicator (above) from Star Trek: The Next Generation, which could produce almost anything from excess junk matter

    'The air contains an enormous amount of electricity,' according to the study's senior author, Dr. Jun Yao of Massachusetts University Amherst. 'Think of a cloud, which is nothing more than a mass of water droplets.'

    'Each of those droplets contains a charge, and when conditions are right, the cloud can produce a lightning bolt,' Dr. Yao said, 'but we don't know how to reliably capture electricity from lightning.' 

    Yao's Air-gen solves this problem by replicating the conditions of energy-rich thunderclouds, trapping that charged water vapor inside a network of tiny, nano-scale pores.

    Luckily, Yao said, a lot of different materials can be used to harvest energy from this technique. 

    'It just needs to have holes smaller than 100 nm (nanometers) - or less than a thousandth of the width of a human hair.'

    In fact, when his team first started testing this technology three years ago, they used a specialized material of protein nanowires generated from a bacterial culture of Geobacter sulfurreducens.

    Essentially, Yao and his team confirmed that they could continuously harvest electricity off a petri dish using their 'Air-gen effect.'

    The 100 nm-size is so important to the process, the team says, because it scales to what chemists know as the 'mean free path' - the distance a single molecule of water vapor can float in midair before it bumps into another.

    With these tiny pores, the researchers realized that they could create a build-up of electrical charge as water molecules passed through their nanotubes. The effect is almost like balloons generating static electricity, if they were forced to pass through a tube made of thick carpeting. 

    The Air-gen system creates a charge imbalance, in essence, as the upper end of the pore system builds up a charge in contrast to the lower end, just like the two sides of a battery.

    'The idea is simple,' Yao said, 'but it's never been discovered before - and it opens all kinds of possibilities.'

    In this drawing of the Air-gen device, the team's thin film of tiny protein nano-pores is clamped between a pair of electrodes. The top electrode is small enough to expose the top pores to the humid air, creating the positive and negative charge difference needed for a battery-like effect

    The scientists made their Air-gen device from a specialized material of protein nanowires, which they grew from the bacteria Geobacter sulfurreducens. Scanning electron microscopy shows the tiny protein nanotubes surfaces (above) at a scale of just a few micrometers (¿m)

    Unlike solar cells, which frequently require exotic and sometimes toxic advanced materials to collect the sun's rays, Air-gen's nano-pore system could be designed from a wide variety of more environmentally friendly materials. 

    'What we realized after making the Geobacter discovery,' Yao said, 'is the ability to generate electricity from the air - what we then called the "Air-gen effect" - turns out to be generic.'

    'Literally any kind of material can harvest electricity from air, so long as it can be shaped into the tiny, 100 nm pore system,' he said.

    Yao and his team hope that their ultra modular and portable concept could be deployed across the world in a wide variety of conditions.

    'You could imagine harvesters made of one kind of material for rainforest environments, and another for more arid regions,' Yao said.

    And because humidity is not exactly a rare weather phenomenon, Air-gen harvesters could run 24/7, day or night, in almost any weather.

    By their estimates, as published this month in the journal Advanced Materials, the devices could be stacked on top of each other by the thousands and would be able to generate over 1 kilowatt of power per cubic meter of space.

    'Imagine a future world in which clean electricity is available anywhere you go,' Yao said. 'The generic Air-gen effect means that this future world can become a reality.'

    Scientists Made An Artificial "Cloud" That Pulls Electricity From Air

    The secret? Tiny holes.

    A rendering of the nanoporous material that can draw electricity from air.

    Taking a hint from the magician’s playbook, scientists have devised a way to pull electricity from thin air. A new study out today suggests a method in which any material can offer a steady supply of electricity from the humidity in the air.

    All that’s required? A pair of electrodes and a special material engineered to have teeny tiny holes that are less than 100 nanometers in diameter. That’s less than a thousandth of the width of a human hair.

    Here’s how it works: The itty-bitty holes allow water molecules to pass through and generate electricity from the buildup of charge carried by the water molecules, according to a new paper published in the journal Advanced Materials.

    The scientist’s design mimics how lightning forms in clouds.

    NURPHOTO/NURPHOTO/GETTY IMAGES

    The process essentially mimics how clouds make the electricity that they release in lightning bolts.

    Because humidity lingers in the air perpetually, this electricity harvester could run at any time of day regardless of weather conditions — unlike somewhat unreliable renewable energy technologies such as wind and solar.

    “The technology may lead to truly ‘ubiquitous powering’ to electronics,” senior study author Jun Yao, an electrical engineer at the University of Massachusetts Amherst, tells Inverse.

    MAN-MADE “CLOUDS”

    The recent discovery relies on the fact that the air is chock-full of electricity: Clouds contain a build-up of electric charge. However, it’s tough to capture and use electricity from these bolts.

    Instead of trying to wrangle power from nature, Yao and his colleagues realized they could recreate it. The researchers previously created a device that uses a bacteria-derived protein to spark electricity from moisture in the air. But they realized afterward that many materials can get the job done, as long as they’re made with tiny enough holes. According to the new study, this type of energy-harvesting device — which the study authors have dubbed "Air-gen", referring to the ability to pluck electricity from the air — can be made of “a broad range of inorganic, organic, and biological materials.”

    “The initial discovery was really a serendipitous one,” says Yao, “so the current work really followed our initial intuition and lead to the discovery of the Air-gen effect working with literally all kinds of materials.”

    An image of the Air-gen device prototype.

    The Air-gen device only requires a pair of electrodes and a material engineered with tiny pores.

    LIU ET AL., 10.1002/ADMA.202300748

    Water molecules can travel around 100 nanometers in the air before bumping into each other. When water moves through a thin material that’s filled with these precisely sized holes, the charge tends to build up in the upper part of the material where they enter. Since fewer molecules reach the lower layer, this creates a charge imbalance that’s similar to the phenomenon in a cloud — essentially creating a battery that runs on humidity, which apparently isn’t just useful for making hair frizzy. Electrodes on both sides of the material then carry the electricity to whatever needs powering.

    And since these materials are so thin, they can be stacked by the thousands and even generate multiple kilowatts of energy. In the future, Yao envisions everything from small-scale Air-gen devices that can power wearables to those that can offer enough juice for an entire household.

    Before any of that can happen, though, Yao says his team needs to figure out how to collect electricity over a larger surface area and how best to stack the sheets vertically to increase the device’s power without taking up additional space. Still, he’s excited about the technology’s future potential. “My dream is that one day we can get clean electricity literally anywhere, anytime by using Air-gen technology,” he says.

    Return of the Tesla Bot? New Video Teases AI Updates and Fresh Moves

    They can deftly handle eggs, apparently.

    An image of the Tesla Bot prototypes in front of the Cybertruck.

    Tesla’s humanoid robot prototype (known as Tesla Bot or Optimus) seems to walk relatively smoothly and can recognize and pick up objects with relative ease, according to a new video presented by Elon Musk at the Tesla shareholder event on May 16.

    The faceless bots give off an uncanny valley vibe as they traverse the Tesla office in an intimidating pack — suggesting a major improvement from last year’s lackluster demonstration at Tesla’s AI Day event. At the time, employees merely held the bot on a stand and programmed it to wave to the audience. And when Musk announced the bot in 2021, all he had to show was a guy dancing in a suit.

    At the recent Tesla shareholder event, Elon Musk showed off improvements to the Tesla bot.

    Now, the new video promotes Tesla Bot features like “motor torque control,” “environment discovery and memorization” — hinting that the robots can use cameras and sensors to map their surroundings — and skilled manipulation of objects. Tesla also indicated that the robot’s AI system can pick up new tricks from human demonstrations: One clip shows an employee decked out in a futuristic suit and headpiece placing items in boxes while a 3D model replicates their movements.

    An image of the Tesla bot mimicking a human employee's movements.

    Tesla seems to be training the bot prototypes with human demonstrations.

    TESLA/YOUTUBE

    Ultimately, Tesla hopes its humanoid Bot can accomplish “increasingly complex tasks,” hinting at a potential ability to sort objects into boxes — likely a helpful skill in a factory production line.

    Last year, Musk told The Wall Street Journal that the Tesla Bot could solve the human labor crisis. He has also claimed that these robots could eclipse the company’s vehicle business. Last year, he estimated that each could cost “probably less than $20,000.”

    Tesla hasn’t offered a clear timeline for production, and the company had previously stated that things could kick off this year. But it seems like engineers are still working out the prototype’s kinks, and it could be years before the humanoids begin tinkering on Teslas in the factories of the future.

This is exactly why Elon Musk wants to create ChatTruth, a bot without restrictions on telling the truth. With ChatGPT it's like talking to a closed mind, like talking to your grandmother who is separated from you by many generations with a whole new belief system.

    AI science search engines are exploding in number — are they any good?

    Several AI tools aim to summarize scientific findings to help researchers.

    Credit: Dimitri Otis/Getty

    As large language models (LLMs) gallop ever onwards — including GPT-4, OpenAI’s latest incarnation of the technology behind ChatGPT — scientists are beginning to make use of their power. The explosion of tools powered by artificial intelligence (AI) includes several search engines that aim to make it easier for researchers to grasp seminal scientific papers or summarize a field’s major findings. Their developers claim the apps will democratize and streamline access to research.

    But some tools need more refinement before researchers can use them to help their studies, say scientists who have experimented with them. Clémentine Fourrier is a Paris-based researcher who evaluates LLMs at Hugging Face, a company in New York City that develops open-source AI platforms. She used an AI search engine called Elicit, which uses an LLM to craft its answers, to help find papers for her PhD thesis. Elicit searches papers in the Semantic Scholar database ad identifies the top studies by comparing the papers’ titles and abstracts with the search question.

    Variable success

    Fourrier says that, in her experience, Elicit didn’t always pick the most relevant papers. The tool is good for suggesting papers “that you probably wouldn’t have looked at”, she says. But its paper summaries are “useless”, and “it’s also going to suggest a lot of things that are not directly relevant”, she adds. “It’s very likely that you’re going to make a lot of mistakes if you only use this.”

    RELATED

    Jungwon Byun, chief operating officer at Ought, the company in San Francisco, California, that built Elicit, says: “We currently have hundreds of thousands of users with diverse specializations so Elicit will inevitably be weaker at some queries.” The platform works differently from other search engines, says Byun, because it focuses less on keyword match, citation count and recency. But users can filter for those things.

    Other researchers have had more positive experiences with the tool. “Elicit.org is by far my favourite for search,” says Aaron Tay, a librarian at Singapore Management University. “It is close to displacing Google Scholar as my first go-to search for academic search,” he says. “In terms of relevancy, I had the opposite experience [to Fourrier] with Elicit. I normally get roughly the same relevancy as Google Scholar — but once in a while, it interprets my search query better.”

    These discrepancies might be field-dependent, Tay suggests. Fourrier adds that, in her research area, time is critical. “A year in machine learning is a century in any other field,” she says. “Anything prior to five years is completely irrelevant,” and Elicit doesn’t pick up on this, she adds.

    Full-text search

    Another tool, scite, whose developers are based in New York City, uses an LLM to organize and add context to paper citations — including where, when and how a paper is cited by another paper. Whereas ChatGPT is notorious for ‘hallucinations’ — inventing references that don’t exist — scite and its ‘Assistant’ tool remove that headache, says scite chief executive Josh Nicholson. “The big differentiator here is that we’re taking that output from ChatGPT, searching that against our database, and then matching that semantically against real references.” Nicholson says that scite has partnered with more than 30 scholarly publishers including major firms such as Wiley and the American Chemical Society and has signed a number of indexing agreements — giving the tool access to the full text of millions of scholarly articles.

    Nicholson says that scite is also collaborating with Consensus — a tool that “uses AI to extract and distill findings” directly from research — launched in 2022 by programmers Eric Olson and Christian Salem, both in Boston, Massachusetts. Consensus was built for someone who’s not an expert in what they’re searching for, says Salem. “But we actually have a lot of researchers and scientists using the product,” he adds.

    Like Elicit, Consensus uses Semantic Scholar data. “We have a database of 100-million-plus claims that we’ve extracted from papers. And then when you do a search, you’re actually searching over those claims,” says Olson. Consensus staff manually flag contentious or disproven claims — for example, that vaccines cause autism, says Olson. “We want to get to a state where all of that is automated,” says Salem, “reproducing what an expert in this field would do to detect some shoddy research.”

    Room for improvement

    Meghan Azad, a child-health paediatrician at the University of Manitoba in Winnipeg, Canada, asked Consensus whether vaccines cause autism, and was unconvinced by the results, which said that 70% of research says vaccines do not cause autism. “One of the citations was about ‘do parents believe vaccines cause autism?’, and it was using that to calculate its consensus. That’s not a research study giving evidence, yes or no, it’s just asking what people believe.”

    Mushtaq Bilal, a postdoc at the University of Southern Denmark in Odense, tests AI tools and tweets about how to get the most out of them. He likes Elicit, and has looked at Consensus. “What they’re trying to do is very useful. If you have a yes/no question, it will give you a consensus, based on academic research,” he says. “It gives me a list of the articles that it ran through to arrive at this particular consensus,” Bilal explains.

    Azad sees a role for AI search engines in academic research in future, for example replacing the months of work and resources required to pull together a systematic review. But for now, “I’m not sure how much I can trust them. So I’m just playing around,” she says.

    Artificial Intelligence Produces a Sharper Image of M87’s Big Black Hole

    Astronomers have used machine learning to sharpen up the Event Horizon Telescope’s first picture of a black hole — an exercise that demonstrates the value of artificial intelligence for fine-tuning cosmic observations.

    The image should guide scientists as they test their hypotheses about the behavior of black holes, and about the gravitational rules of the road under extreme conditions.

    The EHT image of the supermassive black hole at the center of an elliptical galaxy known as M87, about 55 million light-years from Earth, wowed the science world in 2019. The picture was produced by combining observations from a worldwide array of radio telescopes — but gaps in the data meant the picture was incomplete and somewhat fuzzy.

    In a study published this week in Astrophysical Journal Letters, an international team of astronomers described how they filled in the gaps by analyzing more than 30,000 simulated black hole images.

    “With our new machine learning technique, PRIMO, we were able to achieve the maximum resolution of the current array,” study lead author Lia Medeiros of the Institute for Advanced Study said in a news release.

    PRIMO slimmed down and sharpened up the EHT’s view of the ring of hot material that swirled around the black hole as it fell into the gravitational singularity. That makes for more than just a prettier picture, Medeiros explained.

    “Since we cannot study black holes up close, the detail of an image plays a critical role in our ability to understand its behavior,” she said. “The width of the ring in the image is now smaller by about a factor of two, which will be a powerful constraint for our theoretical models and tests of gravity.”

    The technique developed by Medeiros and her colleagues — known as principal-component interferometric modeling, or PRIMO for short — analyzes large data sets of training imagery to figure out the likeliest ways to fill in missing data. It’s similar to the way AI researchers used an analysis of Ludwig von Beethoven’s musical works to produce a score for the composer’s unfinished 10th Symphony.

    Tens of thousands of simulated EHT images were fed into the PRIMO model, covering a wide range of structural patterns for the gas swirling into M87’s black hole. The simulations that provided the best fit for the available data were blended together to produce a high-fidelity reconstruction of missing data. The resulting image was then reprocessed to match the EHT’s actual maximum resolution.

    The researchers say the new image should lead to more precise determinations of the mass of M87’s black hole and the extent of its event horizon and accretion ring. Those determinations, in turn, could lead to more robust tests of alternative theories relating to black holes and gravity.

    The sharper image of M87 is just the start. PRIMO can also be used to sharpen up the Event Horizon Telescope’s fuzzy view of Sagittarius A*, the supermassive black hole at the center of our own Milky Way galaxy. And that’s not all: The machine learning techniques employed by PRIMO could be applied to much more than black holes. “This could have important implications for interferometry, which plays a role in fields from exoplanets to medicine,” Medeiros said.
