Caught U.S. Speaker Nancy Pelosi Plane Landing, Taipei, Taiwan, Video, Aug 2, 2022 World News.
Caught U.S. Speaker Nancy Pelosi Plane Landing, Taipei, Taiwan, Video, Aug 2, 2022 World News.
Hey all, I was on the running track tonight at about 10:40 pm and recorded U.S. Air Force plane that may include House of Representatives Speaker Nancy Pelosi. After seeing it, I checked and saw live news of it landing at that moment! This is her plane. Awesome news she came in safe and sound. Good for Taiwan and America.
Also the fact that Nancy could use this in 2024 to help her get elected as president...seems possible. Or to help enforce a US president in 2024.
China wont take it sitting down. They will punish Taiwan in one form or another. Already the top 100 exporters in Taiwan were banned from sending to China. But I think Lanyu Island being closest to China will be taken over...even now as I type this, two huge China warships sit alongside it...threating its freedom.
Beach in Taiwan, Two Birds Landed On Me, July 30, 2022, Taiwan Breaking News
Beach in Taiwan, Two Birds Landed On Me, July 30, 2022, Taiwan Breaking News
I was at a BNB yesterday and decided to take a walk on the beach looking for fossils and sapphires, when suddenly a bird landed on my shoulder and then another on the other shoulder. I looked up and found two beautiful love birds panting hard from the 100F heat here. I let them ride me while I searched then I decided to carry them back to the BNB area where our neighbor BNB owns the birds, then I visited the mysterious peeing tree which just started this week. There the birds flew onto the tree after riding me 25 min.
Funny thing, one of the birds kept at my necklace until it had unlatched three latches that locked it, before it fell off. I caught it and hid it in my pocket, but then they went for my watch...they love shiny news things. LOL, very playful and curious animals. I fed them back at the BNB and gave them some cold water.
Saudi Arabia plans a massive desert SIDESCRAPER: MBS unveils 75 mile-long, $1 trillion skyscraper called the Mirror Line that will be taller than the Empire State Building and house up to five million people
Saudi Arabia plans a massive desert SIDESCRAPER: MBS unveils 75 mile-long, $1 trillion skyscraper called the Mirror Line that will be taller than the Empire State Building and house up to five million people
Saudi Arabia plans on building a 75-mile skyscraper called the Mirror Line by 2030
Crown Prince Mohammed bin Salman announced in January 2021 and said he wanted to be greater than the Egyptian Pyramids
The Mirror Line will consist of two 1,600 feet tall buildings that run parallels to each other and go across desert, mountains, and coastal areas
When completed, the $1 trillion megabuilding will hold up to 5million people and people will be able to commute end-to-end in 20 minutes
Saudi Arabia has unveiled plans for a $1 trillion, 75 mile long skyscraper made of mirrored glass that will stretch across its desert and stand taller than the Empire State Building.
The Mirror Line will be a part of the desert city called the Neom - that will be around the size of Massachusetts - which Saudi Crown Prince Mohammed bin Salman announced in January 2021.
He did so after saying he wanted his country to house a construction project as iconic and timeless as the Pyramids of Egypt.
'The Line is a project that is a civilizational revolution that puts humans first,' he said at the time.
The Mirror Line will consist of two 1,600 feet tall buildings that run parallel to each other across 75 miles of desert, coastal, and mountain landscapes.
Prince MBS has claimed he wants the Mirror Line to be ready by 2030, although engineers have said it could take 50 years to construct.
The building is so long that it will sit on struts to take the curvature of the Earth into account, and will also have a high speed train line running underneath its length.
If fully completed, the skyscraper will run from the Gulf of Aqaba, through a mountain range, and then extend along the coast into a desert 'aerotropolis,' the Wall Street Journal reported.
Salman also said that the project aimed to allow a million residents to meet within a five-minute walk and to travel end-to-end within a 20-minute stretch. It will also reportedly be powered by renewable energy.

The Mirror Line will have vegetation, including vertical farming, a high-speed train, and create thousands of jobs
The futuristic buildings feature a silver shine and an intricate inside, with stairwells and greenery and homes to create a linear community.
The trillions-of-dollars project is expected to house five million people after its completion and a high-speed train will run underneath the buildings, according to the Wall Street Journal. It will also feature a marina for boats underneath the arch of the buildings.
The community of millions will also be fed through vertical farming that will be integrated into the walls of the shiny buildings and residents will reportedly pay a subscription for three meals a day.
Prince MBS insists the buildings will be totally carbon neutral and good for the local environment.
The reflective buildings will house around five million people and residents will be able to get end-to-end in 20 minutes through renewable energy trains
The Line is located near the coastal area of the country
Desert living won't just be hot, sticky, and sandy, but the Mirror Line will also feature a sports stadium that is set to be 1,000 feet above the ground.
Salman is also hoping the Neom, as a whole, will create thousands of new jobs and let the oil-rich country stop being so dependent on the resource for wealth, according to the Wall Street Journal.
However, foreign investments in the Neom have not been so forthcoming as many Western countries continue to boycott the country over alleged human rights violations. Salman has been accused of ordering the killing of journalist Jamal Khashoggi in 2018, but the Crown Prince has denied any involvement.
Others who have fewer political scruples have questioned whether the projects devised are just too ambitious. Saudi Arabia previously abandoned plans to build a mile-high skyscraper that would have been the world's tallest after getting into funding difficulties.
US President Joe Biden, 79, met with the Crown Prince last week to talk over the broken relationships between the countries. Bitterness between the two subsided a little as Biden is hoping a relationship with the Crown Prince will help lower inflation rates in the US, according to the Wall Street Journal.
High oil prices are actually helping Salman continue forth with the Mirror Line and Neom, as it is providing funding for the expensive project, the Wall Street Journal said.
Salman is hoping to great a desert community known as Neom

The futuristic community is supposed to rival the Egyptian Pyramids
However, Neom also faced human rights criticism when it was announced after tribes were forcibly removed from the area and security allegedly shot a resident dead.
The project's completion date is set for 2030, but builders and urban planners are struggling to resolve many questions. The project was originally set to be completed in 50 years.
Planners are struggling to answer if residents would consider living in a high-rise building after the pandemic, the migration of animals and birds, and how to deal with the structure impacting the flow of groundwater.
Environmental planners say the sheer size and length of the Mirror Line will disrupt migratory bird patterns - and the mirrored glazing of the building could further confuse them, pouring water on the project's desire to be planet-friendly.

Inside Saudi Arabia’s Plan to Build a Skyscraper That Stretches for 75 Miles - WSJ
The Animal Kingdom is full of surprising creatures. There’s millions of crazy critters and some nightmarish animals swiftly crawling around the face of earth we don’t know about. Some of the animals are fearsome whereas others may just look normal. Some of these may seem outrageous for having gigantic size and others may possess distinct features that make them look like aliens. Some animals possess sharp teeth or fangs or numerous legs while other can slither away at super speed. Most of these animals are considered to harmless to mankind.
It's a baffling fact that although the sea serpents of earlier times were seen here, there and everywhere, today they are just about completely gone. As to why, we simply don't know. Fortunately, however, we do have the testimony of sailors, and of the captains of ships. Their reports amount to a huge number.
(Nick Redfern)
With that said, let's have a look back in time, an era when giant monsters almost ruled the waves. For example, the port of Gloucester, Massachusetts was thesite of repeated encounters with massive, dangerous leviathans in the early 17th century. From a man named John Josselyn, we have these words to muse upon: “They told me of a sea serpent, or snake, that lay quoiled [sic] up like a cable upon the rock at Cape Ann; a boat passing by with English on board, and two Indians, they would have shot the serpent, but the Indians dissuaded them, saying that if he were not killed outright, they would all be in danger of their lives.” Obadiah Turner, also in the same time-frame, stated of the creature, in old English style of writing: “Some being on ye great beache gathering of calms and seaweed wch had been cast thereon by ye mightie storm did spy a most wonderful serpent a shorte way off from ye shore. He was big round in ye thickest part as a wine pipe; and they do affirm that he was fifteen fathoms more in length. A most wonderful tale. But ye witnesses be credible, and it would be of no account to them to tell an untrue tale. Wee have likewise heard yt Cape Ann ye people have seene a monster like unto this, whch did there come out of ye land mch to ye terror of them yt did see him.”
It should be stressed that the 19th century was the period in which sea serpents were really in their element, we might say. From 1817, we have the following, notable report from Amos Story: “It was between the hours of twelve and one o’clock when I first saw him, and he continued in sight for an hour and a half. I was setting on the shore, and was about twenty rods from him when he was the nearest to me. His head appeared shaped much like that of the sea turtle, and he carried his head from ten to twelve inches above the surface of the water. His head at that distance appeared larger than the head of any dog I ever saw. From the back of his head to the next part of him that was visible, I should judge to be three or four feet. He moved very rapidly through the water, I should say a mile or two or, at most, in three minutes. I saw no bunches on his back. On this day, I did not see more than ten or twelve feet of his body.” Story’s account was swiftly followed by that of Solomon Allen III, a shipmaster. He said of the incredible beast he spied: “His head formed something like the head of a rattlesnake, but nearly as large as the head of horse. When he moved on the surface of the water his motion was slow, at times playing in circles, and sometimes moving straight forward.”
A particularly detailed account came days later from one Cheever Felch, whose sighting of the Gloucester sea serpent was made when he, Felch, was aboard a U.S. schooner, the Science. He said of the monstrous thing: “His color is dark brown with white under his throat. His size we could not accurately ascertain, but his head is about three feet in circumference, flat and much smaller than his body. We did not see his tail; but from the end of the head to the farthest protuberance was not far from one hundred feet. I speak with a degree of certainty, behind much accustomed to measure and estimate distances and length. I counted fourteen bunches on his back, the first one say ten or twelve feet from this head, and the others about seven feet apart. They decreased in size towards the tail. These bunches were sometimes counted with and sometimes without a glass. Mr. Malborne counted thirteen, Mr. Blake thirteen and fourteen, and the boatman the same number...His motion was partly vertical and partly horizontal, like that of fresh water snakes. I have been much acquainted with snakes in our interior waters. His motion was the same.”
And still the reports kept on coming, as seafarer John Brown noted: “I discovered something about three or four miles distant, about two points on the weather bow, which appeared as a mast, as it rose and sunk in a perpendicular manner, once in about eight or ten minutes. I kept the vessel directly for it, and after look at it with my glass, I observed to my mate that it was a wreck, as I could see timbers sticking up, but as we approached nearer, I found what appeared like timbers to be a number of porpoises and black fish playing and jumping around a large Sea-Serpent, which we had supposed to be the mast.” While there certainly have been sightings of sea serpents in the waters of Gloucester since 1817, none of them – in terms of their frequency, number of witnesses, and credibility – has ever come close to matching those tumultuous, early 19th century days when the people of Gloucester were plagued by a monster.
Nick Redfern
Then, there is this account, which appeared in the British Literary Gazette on August 1, 1818: “Captain Joseph Woodward of the schooner Adamant reported an encounter off the coast of Cape Ann in May, 1818. He said he shot a cannon at the monster. He was quoted as saying that after the cannon shot: ‘The serpent shook its head and its tail in an extraordinary manner and advanced toward the ship with open jaws; I had caused the cannon to be reloaded, but he had come so near that all the crew were seized with terror, and we thought only of getting out of his way. He almost touched the vessel and, had I not tacked as I did, he would certainly have come on board. He dived, but in a moment we saw him come up again with his head on one side of the vessel and his tail on the other as if he was going to lift up and upset us. However we did not feel any shock. He remained five hours near us, only going backward and forward.”
We’ll now take a look at some more, incredible claims of encounters with monsters; cases that amazed and terrified the crews and passengers of ships and boats on the high seas. Rather notably, a number of such reports have been declassified under the terms of the U.K. government’s Freedom of Information Act. They demonstrate something remarkable and illuminating: namely, that highly incredible sources had seen huge, monsters of the oceans and who were willing to attest to the truth of the amazing incidents. Just such a case can be found in the 19th century-era archives of the Admiralty, which was the U.K. equivalent of the United States Navy. The first report that has been declassified by government personnel dates back to 1830, specifically May 9, 1830. As for the crew that had the amazing encounter, they were aboard the Rob Roy, which was a military craft, and while navigating the Atlantic Ocean. Little did the crew know that when the day began, they would soon come face-to-face with a terrifying monster of the mysterious depths. We have the captain of the ship, one James Stockdale, to thank for having the guts to inform senior naval personnel the incredible creature that had been seen.
I will now share with you the unedited words of Captain Stockdale: “About five p.m. all at once while I was walking on the poop my attention was drawn to the water on the port bow by a scuffling noise. Likewise all the watch on deck were drawn to it. Judge my amazement when what should stare us all in the face as if not knowing whether to come over the deck or to go around the stern – but the great big sea snake! Now I have heard of the fellow before – and I have killed snakes twenty-four feet long in the straits of Malacca, but they would go in his mouth. I think he must have been asleep for we were going along very softly two knots an hour, and he seemed as much alarmed as we were – and all taken aback for about fifteen seconds. But he soon was underway and, when fairly off, his head was square with our topsail and his tail was square with the foremast. My ship is 171 feet long overall – and the foremast is 42 feet from the stern which would make the monster about 129 feet long. If I had not seen it I could not have believed it but there was no mistake or doubt of its length – for the brute was so close I could even smell his nasty fishy smell." There's more to come:
“When underway he carried his head about six feet out of water – with a fin between the shoulders about two feet long. I think he was swimming about five miles an hour – for I watched him from the topsail yard till I lost sight of him in about fifty minutes. I hope never to see him more. It is enough to frighten the strong at heart.” The report of Captain Stockdale and his crew was not the only one that ended up in U.K. military files. There was yet another. This one dated from December 13, 1857. Commander George Henry Harrington was so impressed – and worried – by the extraordinary sighting that he quickly put together a full report on the encounter with the giant beast. It reads like this: “While myself and officers were standing on the lee side of the poop – looking toward the island – we were startled by the sight of a huge marine animal which reared its head out of the water within twenty yards of the ship – when it suddenly disappeared for about half a minute and then made a reappearance in the same manner again – showing us its neck and head about ten or twenty feet out of the water.
“Its head was shaped like a long buoy – and I should suppose the diameter to have been seven or eight feet in the largest part with a kind of scroll or ruff encircling it about two feet from the top. The water was discolored for several hundred feet from the head, so much so that on its first appearance my impression was that the ship was in broken waters, produced, as I supposed, by some volcanic agency, since I passed the island before. But the second appearance completely dispelled those fears and assured us that it was a monster of extraordinary length and appeared to be moving slowly towards the land. The ship was going too fast to enable us to reach the masthead in time to form a correct estimate of this extreme length – but from what we saw from the deck we conclude that he must have been over two hundred feet long. The Boatswain and several of the crew, who observed it from the forecastle, state that it was more than double the length of the ship, in which case it must have been five hundred feet. Captain Harrington signed off: “I am convinced that it belonged to the serpent tribe.”
It is often said that the first question a human ever asked was, “Hi, I’m Adam … what’s your name?” Many believe the second-oldest question is, “Which came first … the chicken or the egg?” While the debate on the answer to the first will probably never end, the answer to the second may have been determined by a new study (really!) which resolved the poultry paradox with science.
Place your bets - chicken or egg?
“Little is known about the early history of the chicken (Gallus gallus domesticus), including the timing and circumstances of its introduction into new cultural environments. To evaluate its spatio-temporal spread across Eurasia and north-west Africa, the authors radiocarbon dated 23 chicken bones from presumed early contexts.”
The study, published in the journals Antiquity and The Proceedings of the National Academy of Sciences (PNAS) and led by Professor Joris Peters from the Ludwig Maximilian University of Munich, set out to prove or disprove the commonly held idea that wild chickens were domesticated in either China, India or southeast Asia 10,000 years ago, and were brought to Europe more than 7000 years ago. These dates were easily accepted because domesticated chickens are everywhere and seemingly everyone in every culture eats their meat and their eggs – making them the world’s most domesticated animal. That made it easy for the geographically dispersed research team to collect chicken remains from more than 600 sites in 89 countries – not just bones but also records of burial locations and historical data. Carbon dating of the bones fried the previous chicken domestication estimates.
“Of the 23 dated chicken bones, only five were consistent with their reported stratigraphic phasing. The radiocarbon dates associated with the remaining 18 were more recent than their reported dates.”
Not only were they “more recent,” they were much more recent – bones from Greece thought to date to 1250–1100 BCE were determined to be “post-1954.” That put the researhcers on alert and they used modern chicken bone comparisons to change the date on other alleged Bronze Age fossils. Upon completion of the carbon dating, the first confirmed evidence for a close relationship between humans and chickens came from complete skeletons placed alongside Bronze Age human burials in Dasikongcun, China (1320–1046 BCE), and Ban Non Wat, Thailand (800 BCE). You don’t need a calculator to do the math – that’s nearly 7,000 years after the previously accepted date of 10,000 years ago for the first domesticated chickens in China.
What about Europe and Africa?
“Radiocarbon dating also helped establish age of 23 of the earliest-known chickens in western Europe and northwest Africa. The results show that domesticated chickens arrived in Europe only about 2800 years ago and took another 1000 years to reach the colder climates in the continent’s north.”
The study found chickens in Italy by the eighth century BCE and on the Balearic Islands off eastern Spain between the eighth to sixth century BCE – it’s believed they arrived via early Greek, Etruscan and Phoenician maritime trade routes across the Mediterranean. Moving inland, a skeleton from the Czech Republic and data from Bulgaria show their arrival in the sixth to fifth centuries BCE, with the same time period for France and southern Britain. It looks like chickens didn’t appreciate cold weather -- it took almost 1000 years longer for their arrival in Scotland, Ireland, Scandinavia and Iceland around 800 CE. It appears chickens arrived on the Horn of Africa (the Somali Peninsula in east Adrica) between the ninth and sixth centuries BCE and spread very slowly – not arriving in the north-west until the first century BCE and possibly as late as the medieval period around 500 CE.
Who won?
“The expansion of the Roman Empire helped to popularise chickens and eggs as foodstuffs.”
While their domestication in China and southeast Asia is directly attributable to rice farming and the availability of dried rice for feed, the study credits the Romans for spreading the world’s favorite breakfast dish and dinner meat. Which brings us back to the question: which came first – the chicken or the egg? If we’re talking food, the egg wins – the study shows that chickens were used for ceremonial purposes before being eaten, while humans saw how easily animals ate eggs and followed suit by consuming the eggs of wild chickens, ducks, geese, ostriches, quails and many other larger birds.
What answer did Adam get? That’s for another study to solve.

Date of discovery: May 19, 2022
Location of discovery: Taiwan
Hey all I was looking at a weather map for anomalies and found a big one. I found a face, a human-like angelic face looking down at Taiwan as if assuring it that Taiwan is being looked after by angelic beings. Now last month we had 50 confirmed covid cases per day, today we had 90,000 confirmed cases. Also the threat of China taking over Taiwan is a daily threat over here. But the face, has a look of confidence and happiness as if everything is being dealt with by them. Angels or aliens...its clear that they are a far superior species who are very large, but care about little us. Also did you notice how the air is being exhaled out of the nose of the person and spread across Taiwan? A cleansing, to rid us of covid.

OMG this youtuber going by the name UFOvni2012 has been horrible to me for many years. He did it again yesterday. He stole the whole video that was sent to me. Then he stole me text I wrote about it from my blog post here, word for word, as if he wrote it. I make so many discoveries, but this guy not only bought 140,000 subscribers two months ago, but he steals all his material to make money.
Guys this really makes me want to stop all this altogether. I feel like I've been attacked, like I have been assaulted. This is a horrible feeling.
If you could tell him under his video to stop steal from Scott Waring I would appreciate it.
Mysteries associated with lightnings, ball lightnings and the electrosphere of Earth
Mysteries associated with lightnings, ball lightnings and the electrosphere of Earth
Lightning and ball lightning are electrospheric phenomena involving several poorly understood aspects. Also the origin of the electrosphere of Earth is still a mystery. In the TGD framework it is possible to deduce information about magnetic and electric bodies of Earth (briefly MB and EB) by using empirical inputs and these phenomena.
Ball lightings are known to be real are not understood. Ball lightning-like phenomena can be created also artificially in microwave ovens using match. Matches contain organic material and this serves as a good hint.
There is a New Scientist article, which gives a popular representation of ball lightings (see this). The theory of Cameron (see this) is mentioned in the article. The theory assumes that lightnings are essentially phenomena associated with the electromagnetic radiation field alone and neglects the fact that plasma is very probably involved. The theory relies on exact solutions of Maxwell’s equations and proposes that ball lightnings involve monochromatic electromagnetic fields which are knotted and linked making the field configurations topologically nontrivial. Both magnetic and electric field lines can be knotted. This does not however imply topological stability since the linearity of Maxwell’s equations implies that these field configurations are unstable. The finding that lifetime is long enough for microwave lengths does not conform with the fact that visible light is involved. Another theory mentioned in the article is by Boerner and proposes that lightning comes from another dimension. What this could actually mean, is of course a highly non-trivial question.
The basic mystery is how ball lightning can survive for so long a time. An ordinary plasma ball is not expected to do so. This suggests that ball lightning obeys non-linear dynamics and is some kind of topological entity robust by their topological non-triviality.
A very natural expectation is that ball lightning is a self-organizing system consisting of plasma which radiates. Self-organization requires energy feed. It could come as a Coulombic energy from the electric field of Earth through which part of the plasma of ball lightning has arrived. Here one encounters a problem. The electric resistance of the atmosphere causes a dissipation of the energy so that the charged particles cannot accelerate to high energies. How could lightning avoid this?
Two problems are always better than one. The second puzzle is that ordinary lightnings involve relativistic electrons and gamma rays. This is impossible in standard physics due to the already mentioned electric resistance of the atmosphere. Could ball lightning involve a new phase of matter, for which the dissipation is very small. Perhaps because it interacts very weakly with the ordinary matter of the atmosphere?
The third mystery is that the surface of Earth carries a negative charge, which creates an electric field. This field is essential for the generation of lightning. The origin of this field is however not understood.
There is also a fourth problem. Dark matter exists but there is no generally accepted theory of dark matter. All experiments trying to detect proposed candidates for dark matter particles (the particle physicist’s way to solve a problem is to propose a new particle) have failed. There is of course also the mystery of life but it is better to stop here.
In the sequel a TGD based model for electrosphere is deduced by using various empirical inputs and the TGD based view about dark matter and the model of quantum biology inspired by it. A model, which allows us to understand these phenomena in the TGD framework, is developed. The model relies on the TGD based model of dark matter residing at the flux tubes of the magnetic body. The gravitational magnetic bodies of both Earth and Sun are important.The notion of the electric body of Earth as an analog of the cell membrane acting as a generalized Josephson junction is developed. Lightning and ball lightning would be associated with the analog of action potential.
Antarctica Lost an Ice Shelf, but Gained an Island
Antarctica Lost an Ice Shelf, but Gained an Island
Collapsing ice shelves on the eastern coast of Antarctica has revealed something never seen before: a landform that might be an island. But this is not the first newly revealed island off the Antarctic coast. A series of islands have appeared as the ice shelves along the continent’s coastline has disintegrated over the past few years.
The island is visible in the three images, which were taken by Landsat satellites between 1989 and 2022. The landform maintains its shape, even through the ice around it has melted, shifted, and disappeared. With the collapsing ice, scientists think large icebergs likely smashed into the island, but the island maintained its shape.
The eastern coast of Antarctica has lost most of the Glenzer and Conger ice shelves, as seen in these satellite images taken between November 15, 1989 – January 9, 2022. Credit: NASA GSFC/UMBC JCET.
However, scientists are unsure if there is any solid earth below the mound of snow and ice.
“It is undoubtedly similar to other ice islands, such as Bowman Island (also visible in the image above),” said John Gibson, a scientist with the Australian Antarctic Division, in a post on NASA’s Earth Observatory. Gibson thinks the feature is likely an ice island: a large, heavy cap of ice sitting solidly on an underwater peak.
Gibson called the ice island “self-perpetuating,” meaning that snow and ice accumulating on the island’s surface balances out the amount of melting that occurs underwater. If that balance becomes disrupted by a decrease in snowfall, then the ice island could thin and float away. “The unnamed island is a more-or-less permanent feature of the landscape,” Gibson said, “but may someday detach from the underlying rock and become an iceberg.”
NASA says that elevation data in December 2021 from the Advanced Topographic Laser Altimeter System (ATLAS) on NASA’s Ice, Cloud, and land Elevation Satellite 2 (ICESat-2) shows at least part of the island stands 30 to 35 meters (100 to 115 feet) above the surface of the sea.
NASA says that most of the Glenzer and Conger ice shelves are gone, having collapsed earlier this year. And with further collapse of Antarctic ice shelves due to the warming ocean, more of these islands might be popping up.
“The discovery of more of them is likely to continue in the years ahead due to shrinking glacial and sea ice,” said Christopher Shuman, a University of Maryland, Baltimore County, glaciologist based at NASA’s Goddard Space Flight Center. “Obviously these are ‘new to us’ features, but we also have more people and more tools to look at the margins of Antarctica now. Several examples do not make a trend, but they do imply that other once-hidden features are likely to be noticed in the years to come.”
Worlds Biggest and Most Mysterious Snakes Ever Found
Worlds Biggest and Most Mysterious Snakes Ever Found
Snakes—you either think they’re the most fascinating creature on the planet or, you know, downright disgusting. Either way, we humans bow down to the boas of the world because not only are they bigger than us, but they’re stronger for sure and probably hungrier than us, too. In fact, there are more than 3,000 varieties of snakes slithering around the globe and the biggest serpents? Well, let’s just say they put the garden snake in your backyard to absolute sssshame.
Bats will have a large contribution to virus transmission between species in the future, a modelling study finds.

Over the next 50 years, climate change could drive more than 15,000 new cases of mammals transmitting viruses to other mammals, according to a study published in Nature1. It’s one of the first to predict how global warming will shift wildlife habitats and increase encounters between species capable of swapping pathogens, and to quantify how many times viruses are expected to jump between species.
Many researchers say that the COVID-19 pandemic probably started when a previously unknown coronavirus passed from a wild animal to a human: a process called zoonotic transmission. A predicted rise in viruses jumping between species could trigger more outbreaks, posing a serious threat to human and animal health alike, the study warns — providing all the more reason for governments and health organizations to invest in pathogen surveillance and to improve health-care infrastructure.
The study is “a critical first step in understanding the future risk of climate and land-use change on the next pandemic”, says Kate Jones, who models interactions between ecosystems and human health at University College London.
The research predicts that much of the new virus transmission will happen when species meet for the first time as they move to cooler locales because of rising temperatures. And it projects that this will occur most often in species-rich ecosystems at high elevations, particularly areas of Africa and Asia, and in areas that are densely populated by humans, including Africa’s Sahel region, India and Indonesia. Assuming that the planet warms by no more than 2 °C above pre-industrial temperatures this century — a future predicted by some climate analyses — the number of first-time meetings between species will double by 2070, creating virus-transmission hotspots, the study says.
“This work provides us with more incontrovertible evidence that the coming decades will not only be hotter, but sicker,” says Gregory Albery, a disease ecologist at Georgetown University in Washington DC and a co-author of the study.
The challenges of modelling
To make their predictions, Albery and his colleagues developed and tested models, and ran simulations over a five-year period. They combined models of virus transmission and species distribution under various climate-change scenarios, focusing on mammals because of their relevance to human health.
Source: Ref. 1
The team built the species-distribution model to predict where mammals would move to find more liveable habitats as the planet warms. The virus-transmission model predicts the probability of a virus jumping between species for the first time, by taking into account where species might meet as their habitats shift and how closely related they are evolutionarily (viruses are most likely to transmit between related species).
The modelling seems “technically impeccable”, says Ignacio Morales-Castilla, a global-change ecologist at the University of Alcalá, Spain, although he points out that forecasting exercises such as this sometimes need to include unrealistic assumptions. But he adds that the breadth and scope of the research and its ability to identify which parts of the world might be most at risk “clearly stand out”.
One assumption the researchers had to make was about how far and wide species would spread as the climate changes. But factors such as whether mammals can adapt to local conditions or physically cross barriers in landscapes are difficult to predict.
Bats are projected to be involved in viral transmission regardless of these factors, the study found. Thought to be part of the origins of COVID-19, bats are known reservoirs of viruses and make up about 20% of mammals. The team says that — in part because bats can fly — they are less likely to experience barriers to shifting their habitats.
Spillovers to humans?
Although Jones applauds the study, she urges caution when discussing its implications for human health. “Predicting the risk of viral jumps from mammals into humans is more tricky, as these spillovers take place in a complex ecological and human socio-economic environment,” she says.
Many factors could reduce the risk to human health, including increased investment in health care or a virus being unable to infect humans for some reason, she adds.
But the researchers urge that there is no time to waste. Earth has already warmed by more than 1 °C above pre-industrial temperatures, and this is driving species migration and disease swapping. “It’s happening and it’s not preventable, even in the best climate-change scenarios,” Albery says.
Albery and one of his co-authors, Colin Carlson, a global-change biologist also at Georgetown University, say that even though some increase in disease transmission is inevitable, that is no excuse for inaction. The researchers call on governments and the international community to improve the monitoring and surveillance of wild animals and zoonotic diseases, particularly in future hotspots such as southeast Asia. Improving health infrastructure is also essential, they say.
As people begin to prepare for and adapt to global warming, most efforts focus on activities such as halting deforestation or reinforcing sea walls. But Carlson says pandemic preparedness and disease surveillance are climate-change adaptation, too.

All kinds of videos and photos of UFOs have been published on social networks, in which their authors claim to have seen the strange objects in the sky.
A few days ago we talked about Jeremy Corbell and the leak of a video by the US Navy. And we recently talked about the incredible sighting of a triangular craft coming out of the moon.
Now, we have before us something unusual and very clear. If they were “alien ships” this means that they are not hiding from anything, since this filming was made on September 18, 2013, supposedly east of Wittenberg, Germany.
If we are looking at terrestrial ships in the shape of a triangle, such as the TR3-B, they undoubtedly contain unknown technology, and that can be noticed and seen in a fragment of the recording.
Are we facing something real? Although this comes from the year 2013, such as the persecution of an object similar to the ‘tic tak’ of Puerto Rico, the dates have nothing to do, the important thing is to know the truth.
Two ships similar to the TR-3B , at first, can be noticed in the filming, an incredible display of high technology never seen before, by the dexterity they perform.
Without a doubt, if this is real, this is probably the best UFO recording we have ever seen.
The comments on this recording range from the speed that one of the ships takes, to which they say it cannot be human, until it may be a drone.
But does a drone have this shape? That is the big question. What are we facing? Real or fake from the year 2013?

Michio Kaku: 3 mind-blowing predictions about the future
What lies in store for humanity? Theoretical physicist Michio Kaku explains how different life will be for your descendants—and maybe your future self, if the timing works out.
Carl Sagan believed humanity needed to become a multi-planet species as an insurance policy against the next huge catastrophe on Earth. Now, Elon Musk is working to see that mission through, starting with a colony of a million humans on Mars. Where will our species go next?
Theoretical physicist Michio Kaku looks decades into the future and makes three bold predictions about human space travel, the potential of “brain net”, and our coming victory over cancer.
“[I]n the future, the word ‘tumor’ will disappear from the English language,” says Kaku. “We will have years of warning that there is a colony of cancer cells growing in our body. And our descendants will wonder: How could we fear cancer so much?”
Strangest Tree and Plant Species You Don't Believe are Real
Strangest Tree and Plant Species You Don't Believe are Real
Evolution has thrown up some odd but also some impressive looking plants and trees over time. Throughout the years, mother-nature has baffled us with her strange and unusual creations. With more than 298,000 species of plants on earth, we are surely going to find some bizarre plants among them.
IT HAS BEEN MORE THAN 10,000 years since the last fur-covered woolly mammoth feet lumbered across the Arctic tundra.
Once a keystone species of these frozen ecosystems, the legacy of mammoths now has to be painstakingly recovered from layers of ice and permafrost by anorak-clad scientists. But not for much longer.
On September 13, entrepreneur Ben Lamm and Harvard geneticist George Churchannounced the creation of Colossal, a new gene-editing company bent on “de-extincting” the woolly using CRISPR. The company claims that rewilding of this species in the Arctic tundra could revitalize the region's grasslands as a major source of carbon sequestration, which offers a crucial tool in the fight against climate change.
“IT ISN'T DE-EXTINCTION AT ALL.”
With starting capital of $15 million and four-to-six years of research, Lamm tells Inverse the company could produce a “herd” of woolly mammoths calves for the first time since the Ice Age. This means the first baby mammoths could roam the tundra by 2027 or earlier.
But other scientists aren’t so convinced, including Tori Herridge, an evolutionary biologist working as a fellow at the Natural History Museum in London and science communicator. Before the company’s announcement, Herridge was approached to join Colossal’s advisory board but declined.
Herridge tells Inverse that this project could easily blow past some crucial ethical barriers if Colossal isn't careful.
“If [this technology] genuinely does what they hope it's going to do, that will fundamentally alter the way that we as humans interact with the natural world,” says Herridge.
And there’s another issue: it may not be a true mammoth at all.

WHAT IS COLOSSAL?
Using cutting-edge technology to bring a species back from extinction might sound like Jurassic Park-level science fiction, but Colossal’s new project is actually not the first to attempt — or achieve this.
“COLOSSAL IS READY TO CHART THIS NEW FRONTIER OF SCIENCE AND BIOTECHNOLOGY.”
While the company’s use of CRISPR — a gene-editing tool that can snip and replace particular genes in an animal's DNA — is relatively novel, Herridge says that scientists accomplished small-level “de-extinction” years ago through cloning a recently extinct Pyrenean ibex.
What really sets Colossal apart from previous attempts, says Herridge, is their private funding.
Another secret weapon in their corner, according to Lamm, is geneticist and co-founder George Church. With a passionate interest in the woolly mammoth, a deep understanding of synthetic biology, and eight years of research on the topic under his belt, Church is a triple threat. Mix that expertise with $15 million, and Lamm is confident they’ve got a winning combination.
“De-extinction of the woolly mammoth will be the first time a species has been successfully brought back from extinction,” Lamm says. “Colossal is ready to chart this new frontier of science and biotechnology.”
ARE WE REALLY BRINGING BACK THE MAMMOTH?
While CRISPR technology can do miraculous things, Herridge warns that it is still by no means a time machine.
“It isn't de-extinction at all — you're never going to bring back an extinct creature,” says Herridge. “It is not the de-extinction of the mammoth; it is the genetic modification of an elephant you are creating an entirely new synthetic organism.”
When it comes to gene editing, just because it looks like a woolly mammoth and moves like a woolly mammoth doesn’t mean it actually is a woolly mammoth. These mammoth-like animals will instead be more of a hybrid of this ancient species and their modern cousin, the Asian elephant.Shutterstock
Instead of reintroducing so-called authentic woolly mammoths to the tundra, Herridge says that what Church and his team are really doing is tinkering with the DNA of modern-day elephants to create something very similar to a woolly mammoth.
To do this, Church’s team has isolated 60 genes that helped woolly mammoths adapt to cold environments, including developing a shaggy coat, growing smaller ears and tail, and producing extra body fat.
Lamm says that these precisely edited genes will be inserted into the genome of Asian elephants using CRISPR. These “mammoth-like cells” can then, in theory, be inserted into the egg cell of an Asian elephant in place of its full-elephant nucleus.
“Electrical pulses are applied to the egg cell, which will simulate fertilization, and the egg cell will start to divide and grow, becoming an embryo,” says Lamm. Such future embryos could then be implanted in a surrogate elephant or an artificial womb for their 18-22 months-long gestation.
The final result? The world’s first “woolly mammoth” calves in 10 millennia.
HOW IT COULD GO WRONG
But before we get there, Herridge says there’s still a lot that could go wrong along the way. For example, reintroducing species to their native environments without disrupting those ecosystems is tricky even with modern species, but rewilding a species that’s been gone as long as the woolly mammoth could be the most difficult yet — not to mention that the environment they’re being reintroduced to is rapidly changing as temperatures across the world rise.
But while these are points to consider carefully, Herridge says there’s an even more salient ethical issue that this project must keep in mind.
“The worst outcome for me in the short term would be a sort of gung ho approach to implantation and uses elephants as surrogates,” says Herridge.
Moving too quickly in this gene-editing process could have deadly consequences.Shutterstock
According to Herridge, the only way to find out if you’ve done the right tinkering to create a “mammoth,” instead of an animal that might have several abnormalities or deformities, would be to see what kind of calf it creates. In that case, jumping to surrogacy too quickly without significant lab-bench experimentation first would be “unethical,” she says.
One way to get this right is to increase transparency wherever possible, says Herridge. This means releasing data from the Church lab more readily than has been done so far, she says.
HOW IT COULD GO RIGHT
Despite her concerns, Herridge is still optimistic about what we might learn along the way to producing baby woolly mammoths — whether we ever get there or not.
“The best outcome would be amazing collateral advances in our knowledge about mammoths and the ice age ecosystem [and] the application of those biotechnology tools to really press conservation issues for species that are close to extinction today,” says Herridge. “That's what I think would be the most important stuff.”
The quake was so ruinous, humans fled the area for 1,000 years.
The earthquake sent waves as high as 66 feet 5000 miles across the Pacific Ocean.

Archaeologists have found evidence of the largest known earthquake in human history — a terrifying magnitude-9.5 megaquake that caused a 5,000-mile-long (8,000 kilometers) tsunami and prompted human populations to abandon nearby coastlines for 1,000 years, a new study finds.
The earthquake struck about 3,800 years ago in what is now northern Chile when a tectonic plate rupture lifted the region's coastline. The subsequent tsunami was so powerful, it created waves as high as 66 feet (20 meters) and traveled all the way to New Zealand, where it hurled car-size boulders hundreds of miles inland, the researchers found.
Until now, the largest earthquake ever recorded was the 1960 Valdivia earthquake, which hit southern Chile with a magnitude between 9.4 and 9.6, killing up to 6,000 people and sending tsunamis barreling across the Pacific Ocean. The rupture that caused the Valdivia earthquake was enormous, extending as far as 500 miles (800 km) in length. But, as scientists detail in research published April 6 in the journal Science Advances, the newly discovered ancient megaquake was even bigger, coming from a rupture roughly 620 miles (1,000 km) long.
"It had been thought that there could not be an event of that size in the north of the country simply because you could not get a long enough rupture," study co-author James Goff, a geologist at the University of Southampton in England, said in a statement.
Like the Valdivia earthquake, the ancient quake was a megathrust earthquake, the most powerful type of earthquake in the world. These earthquakes occur when one of Earth's tectonic plates gets forced, or subducted, underneath another. The two plates eventually get locked into place by friction, but the forces that caused the plates to collide continue to build. Eventually, so much strain gathers that the point of contact between the plates rips apart, creating a gigantic rupture and releasing energy in the form of devastating seismic waves.
Evidence for the giant quake was found in marine and coastal items — such as littoral deposits (boulders, pebbles and sand native to coastal regions) and marine rocks, shells and sea life — that the researchers discovered displaced far inland in Chile's Atacama Desert.
"We found evidence of marine sediments and a lot of beasties that would have been living quietly in the sea before being thrown inland," Goff said in the statement. "And we found all these very high up and a long way inland, so it could not have been a storm that put them there."
To get a better sense of what brought these deposits so far from the sea, the researchers used radiocarbon dating. This method involves measuring the quantities of carbon 14, a radioactive carbon isotope, found inside a material to determine its age. As carbon 14 is everywhere on Earth, deposits easily absorb it while they form. The half-life of carbon 14, or the time it takes for half of it to radioactively decay, is 5,730 years, making it ideal for scientists who want to peer back into the last 50,000 years of history by checking how much undecayed carbon 14 a material has.
After dating 17 deposits across seven separate dig sites over 370 miles (600 km) of Chile's northern coast, the researchers found that the ages of the out-of-place coastal material suggested that it had been washed inland some 3,800 years ago.
Further evidence also came in the form of ancient stone structures that the archaeologists excavated. These stone walls, built by humans, were found lying beneath the tsunami's deposits, and some were lying backward, pointing toward the sea, suggesting that they had been toppled by the strong currents of the tsunami's backwash.
"The local population there were left with nothing," Goff said. "Our archaeological work found that a huge social upheaval followed as communities moved inland beyond the reach of tsunamis. It was over 1,000 years before people returned to live at the coast again, which is an amazing length of time given that they relied on the sea for food.
As this is the oldest known discovery in the Southern Hemisphere of an earthquake and tsunami devastating human lives, the researchers are excited to probe the region further. They think their research could better inform us of the potential dangers of future megathrust quakes.
"While this had a major impact on people in Chile, the South Pacific islands were uninhabited when they took a pummeling from the tsunami 3,800 years ago," Goff said. "But they are all well-populated now, and many are popular tourist destinations. So when such an event occurs next time, the consequences could be catastrophic unless we learn from these findings."
A new global analysis of the last 19 million years of seafloor spreading rates found they have been slowing down. Geologists want to know why the seafloor is getting sluggish.
New oceanic crust forms continuously along rifts thousands of miles long on the seafloor, driven by plate tectonics. As subduction pulls old crust down, rifts open up like fissures in an effusive volcano, drawing hot crust toward the surface. Once at the surface, the crust begins to cool and gets pushed away from the rift, replaced by hotter, younger crust.
Painting of the Mid-Ocean Ridge with rift axis by Heinrich Berann based on the scientific profiles of Marie Tharp and Bruce Heezen (1977).
This cycle is called seafloor spreading, and its rate shapes many global processes, including sea level and the carbon cycle. Faster rates tend to cause more volcanic activity, which releases greenhouse gases, so deciphering spreading rates helps contextualize long-term changes in the atmosphere.
Dalton and her co-authors studied magnetic records for 18 of the world's largest spreading ridges, using seafloor ages and their areas to calculate how much ocean crust each ridge has produced over the last 19 million years. Each ridge evolved a little differently: some lengthened, some shrank; some sped up, but almost all slowed down. The overall result of Dalton's work is that average seafloor spreading slowed down by as much as 40% over that time.

Today, spreading rates top out around 140 millimeters per year, but peaked around 200 millimeters per year just 15 million years ago in some places, according to the new study. The study was published in the AGU journal Geophysical Research Letters, which publishes high-impact, short-format reports with immediate implications spanning all Earth and space sciences.
The slowdown is a global average, the result of varying spreading rates from ridge to ridge. The study examined 18 ridges, but took a particularly close look at the eastern Pacific, home to some of the globe's fastest spreading ridges. Because these slowed greatly, some by nearly 100 millimeters per year slower compared to 19 million years ago, they dragged down the world's average spreading rates.
It's a complex problem to solve, made more difficult by the seafloor's slow and steady self-destruction.
"We know more about the surfaces of some other planets than we do our own seafloor," said Colleen Dalton, a geophysicist at Brown University who led the new study. "One of the challenges is the lack of perfect preservation. The seafloor is destroyed, so we're left with an incomplete record."
The seafloor is destroyed in subduction zones, where oceanic crust slides under continents and sinks back into the mantle, and is reforged at seafloor spreading ridges. This cycle of creation and destruction takes about every 180 million years, the age of the oldest seafloor. The crust's magnetic record tracks this pattern, producing identifiable strips every time the Earth's magnetic field reverses.
Dalton and her co-authors studied magnetic records for 18 of the world's largest spreading ridges, using seafloor ages and their areas to calculate how much ocean crust each ridge has produced over the last 19 million years. Each ridge evolved a little differently: some lengthened, some shrank; some sped up, but almost all slowed down. The overall result of Dalton's work is that average seafloor spreading slowed down by as much as 40% over that time.
The driver here might be located at subduction zones rather than spreading ridges: for example, as the Andes grow along the western edge of the South American continent, the mountains push down on the crust.
"Think of it as increased friction between the two colliding tectonic plates," Dalton said. "A slowdown in convergence there could ultimately cause a slowdown in spreading at nearby ridges." A similar process could have operated underneath the Himalaya, with the rapidly growing range slowing spreading along the ridges in the Indian Ocean.
However, Dalton points out, this added friction can't be the only driver of the slowdown, because she found slowing rates globally and mountain growth is regional. Larger-scale processes, like changes in mantle convection, could also be playing a role. In all likelihood, she concludes, it's a combination of both. To learn more, Dalton hopes to collect absolute plate speeds, rather than the relative speeds used in this study, which will better allow her to determine the cause of the slowdown.
OCEANISCHE SPREIDING GAAT STEEDS LANGZAMER - EN WETENSCHAPPERS BEGRIJPEN ER NIETS VAN
OCEANISCHE SPREIDING GAAT STEEDS LANGZAMER - EN WETENSCHAPPERS BEGRIJPEN ER NIETS VAN

Tragere spreidingssnelheden kunnen leiden tot een daling van de uitstoot van broeikasgassen door vulkanen. En dus willen onderzoekers hier het fijne van weten.
Wetenschappers hebben ineen nieuwe studie de zogenaamde ‘oceanische spreiding’ gedurende de afgelopen 19 miljoen jaar geanalyseerd. Het leidt tot een frappante ontdekking. Want uit de analyse blijkt dat de oceanische spreiding tegenwoordig een stuk langzamer gaat. Maar waarom?
Oceanische spreiding Aangedreven door platentektoniek vormt zich voortdurend een nieuwe oceanische korst langs duizenden kilometers lange spleten op de zeebodem. In zekere zin zou je kunnen zeggen dat het aardoppervlak hier dus groeit. Maar onze planeet wordt niet groter, doordat de groei gecompenseerd wordt door subductie die elders plaatsvindt. Hierbij wordt de oude korst naar beneden getrokken. Uit de aardmantel komt warm materiaal omhoog in de vorm van magma, dat de ruimte die in de korst ontstaat, opvult. Dit magma zorgt vervolgens voor vulkanisme op de plaatgrens, waardoor er een nieuwe korst van gestold magma wordt gevormd. Eenmaal aan de oppervlakte koelt de korst af en wordt weggeduwd van de spleet waar vervolgens weer meer nieuwe korst kan ontstaan. En deze cyclus noemen we oceanische spreiding.

Snelheid De snelheid van de oceanische spreiding bepaalt veel mondiale processen, waaronder het zeeniveau en de koolstofcyclus. Wanneer de oceanische spreiding versnelt, kan dit leiden tot meer vulkanisme, waardoor er weer meer broeikasgassen vrijkomen. Wanneer de oceanische spreiding vertraagt, kan dit juist leiden tot een daling van de uitstoot van broeikasgassen door vulkanen. Kortom, het ontcijferen van de spreidingssnelheden helpt om langetermijnveranderingen in de atmosfeer in kaart te brengen.
Studie In het nieuwe onderzoek bestudeerde het team 18 verschillende oceanische ruggen waar oceanische spreiding plaatsvindt. In het bijzonder concentreerden de onderzoekers zich op ruggen in de oostelijke Stille Oceaan. De onderzoekers bepaalden de leeftijd van de zeebodem om zo te berekenen hoeveel oceaankorst elke rug in de afgelopen 19 miljoen jaar heeft gevormd.
Langzamer Uit de resultaten blijkt dat elke rug een beetje anders is geëvolueerd; sommige werden langer terwijl andere slonken. Maar opvallend genoeg was er één gemeenschappelijke deler: op bijna alle ruggen verloopt de oceanische spreiding tegenwoordig een stuk langzamer. De onderzoekers komen zelfs tot de verrassende ontdekking dat de gemiddelde oceanische verspreiding gedurende de laatste 19 miljoen jaar met maar liefst 40 procent is vertraagd.
Waarom? De prangende vraag is natuurlijk waarom de oceanische spreiding vertraagt. Dit is echter niet zo gemakkelijk te achterhalen, mede door de langzame en gestage zelfvernietiging van de zeebodem (in de eerder genoemde subductiezones). “We weten meer over de oppervlakken van sommige andere planeten dan over onze eigen zeebodem,” zegt onderzoeker Colleen Dalton. “Eén van de uitdagingen is het gebrek aan bewaring. De zeebodem wordt vernietigd, dus we beschikken niet over alle informatie.”
Subductiezones De onderzoekers hebben wel een theorie. Zo vermoeden ze dat we het antwoord in de subductiezones moeten zoeken. Als de Andes bijvoorbeeld groeit aan de westelijke rand van het Zuid-Amerikaanse continent, dan drukken de bergen op de korst. “Zie het als een verhoogde wrijving tussen twee botsende, tektonische platen,” legt Dalton uit. “Een vertraging van de convergentie zou daar uiteindelijk een vertraging van de verspreiding op nabijgelegen bergkammen kunnen veroorzaken.”
Combinatie Dalton wijst er echter op dat deze extra wrijving niet de enige oorzaak van de vertraging hoeft te zijn. Ook grootschaligere processen, zoals veranderingen in mantelconvectie, kunnen een rol spelen. “Naar alle waarschijnlijkheid is het een combinatie van beide,” zo concludeert ze.
Waarom de oceanische verspreiding dus vertraagt? Vooralsnog moeten onderzoekers ons het antwoord schuldig blijven. Om het mysterie te onthullen, hoopt Dalton in vervolgonderzoek absolute, plaatselijke spreidingssnelheden te verzamelen. Hierdoor denkt ze de oorzaak van de vertraging beter te kunnen bepalen.
