Former Elon Musk employee speaks out on 'ridiclous' death of Neuralink's monkeys
Former Elon Musk employee speaks out on 'ridiclous' death of Neuralink's monkeys
A new report from Wired has alleged that Elon Musk's Neuralink - a neurotechnology company developing a brain-computer interface - euthanised the company's macaque subjects after they suffered various complications from the implant. The report comes after human-test subjects were recently approved for Neuralink's clinical trial. Elon Musk had claimed earlier this month that "no monkey has died as a result of a Neuralink implant, but public documents obtained by the Physicians Committee for Responsible Medicine (PCRM) and seen by Wired, suggest that the primate subjects suffered complications including "bloody diarrhoea, partial paralysis, and cerebral edema." Musk had acknowledged the deaths on September 10 on Twitter/X, denying the deaths were "a result of a Neuralink implant", and that researchers had selected subjects who were already "close to death." However an anonymous former employee called this "ridiculous" if not a "straight fabrication." However, the public records reviewed by Wired suggest a different story. The PCRM, a nonprofit aiming to abolish live animal testing, claim that Musk knew his comments about the primate subjects deaths "to be false". They write that investors deserve to hear the truth about the safety, "and thus the marketability," of Neuralink's product. A December 2019 experiment outlined in one of the documents mentioned a subject known as Animal 15. The documents said that the subject "began to press her head against the floor for no apparent reason" just days after receiving the implant. Her condition only worsened as she "began to lose coordination" and "would shake uncontrollably when she saw lab workers." Staff finally euthanised her months later. Last year, the PCRM filed a complaint with the US Department of Agriculture (USDA) alleging that Neuralink's practices violate the Animal Welfare Act. The US Department of Transportation is also investigating Neuralink over allegations contimanted devices that were removed from monkeys' brains were illegally transported.

A scientist has discovered when Earth's first continent was formed
A scientist has discovered when Earth's first continent was formed
A researcher has figured out that the Earth’s first continent was formed 3bn years ago, in a new paper that sheds fresh light on the early stages of the planet’s life. Jane Greaves, an astronomy professor in the School of Physics and Astronomy at Cardiff University in Wales, was examining continent formation on distant stars and planets. It is thought that exoplanets with continents that formed in a similar way to Earth’s are more likely to be habitable, and perhaps even contain alien life. In the process, she calculated when several distant planets’ continents were born, as well as those a little closer to home. Continents on Earth sit on top of the planet’s hot, viscous mantle. Heat from the inner core stops the mantle from solidifying. The reason the core is hot is because it contains radioactive elements that came from neutron star collisions billions of years ago such as forms of Uranium, Thorium and Potassium. By analysing how many materials like this are present on Earth and on other planets, we are also able to estimate when the continents formed. On Earth, that was about 9.5 billion years since the beginning of the universe. Meanwhile, in Greaves' sample, the first continents appeared 2bn years before Earth’s on the exoplanets of younger, so-called thin disk stars. Older, thick disk stars analysed in her work produced rocky planets with continents that appeared even earlier: about 4 to 5bn years before Earth’s. “The outlook seems very promising for finding rocky exoplanets with continents, given that nearby Sun-like stars have already produced a few candidate hosts,” she wrote. The study, “When were the First Exocontinents?” is published in Research Notes of the American Astronomical SocietySign up to our free Indy100 weekly newsletter Have your say in our news democracy.

Scientists confirm that one of Mexican aliens is 'alive' after controversial research
Scientists confirm that one of Mexican aliens is 'alive' after controversial research
Scientists in Mexico have given their verdict on the supposed 'aliens' that were presented to the country's congress last week. Much controversy existed around the aliens who were presented by a man named Jaime Maussan who has previously been accused of using the mummified beings, apparently found in Peru, as part of an elaborate hoax. Despite spawning dozens of memes, the aliens are apparently being treated seriously enough that they have now been studied by scientists who have said that the figures are ‘single skeletons’ and also have 'eggs' inside of them. The two aliens have been named Clara and Mauricio and have reportedly been studied in a lab at the Noor Clinic in Mexico. Lead researcher Dr Jose de Jesus Zalce Benitez, a former navy forensics doctor, who added that as well as being "a single skeleton" the aliens are also a "complete organic being." He also denied that the aliens were part of a hoax and even said that Clara was "alive, was intact, was biological and was in gestation." However, much like the alien bodies themselves, the research has been clouded in controversy and scepticism as the research has yet to be officially verified, with Nasa scientist Dr David Spergel questioning why the findings haven't been made public, as per the BBC. Spergel said: "He said: "If you have something strange, make samples available to the world scientific community and we'll see what's there." Benitez did add in his address at the press conference: "We are facing the paradigm of describing a new species or given the opportunity to accept that there has been contact with other beings, non-humans, that were drawn and marked in the past by diverse cultures throughout the world."

Scientists have discovered a new fly that fails its one job
Scientist have discovered a fly that... can't fly. In December 2021, the John Midgley and Burgert Muller from the Diversity of Pollinating Diptera in South African Biodiversity Hotspots project went to Lesotho, the only country in the world that has its entire territory located at an altitude of 1,000 metres and higher to see what they could find. At the Afriski mountain resort, they found 51 male specimens of Atherimorpha latipennis (a species discovered in 1956 but whose female had never been described) and a for the first time a female belonging to the same species which couldn't get off the ground. “It’s not unheard of for only the female of a species to be flightless,” says Midgley. “But there were no examples in this fly’s family, let alone its genus.” Martin Hauser, a senior dipterologist at the California Department of Food and Agriculture, who was not involved in the research, told the Guardian: “Active flight has only originated four times in the last three billion years, so it’s always interesting when a species loses the ability to fly. It isn’t super surprising to find flightless species. But it is remarkable when the first case of flightlessness is reported in a family.” Scientists could only make educated guesses about why the female had lost the ability to fly. Despite it being much faster than walking, allowing flies to escape predators. “flight is also costly,” said Midgley. “You have to grow wings, and it uses a lot more energy than walking.” “For the males it is worth flying around and being able to search a larger area for females,” said Hauser. “Even if, while flying, they are exposed to birds and other predators, and risk being blown off the mountain and ending up in a hot valley with no females.” Meanwhile, there are other species that can't fly like ostriches, kiwi and emus. It is thought they evolved to lose flight after the dinosaurs became extinct because there were no predators big enough to hunt them. Fly - you had one job...

Man who stayed awake for 11 straight days shares how his brain ‘broke down’
Man who stayed awake for 11 straight days shares how his brain ‘broke down’
A man who stayed awake for 11 straight days to set a world record has spoken about how he experienced his brain starting to ‘break down’. Englishman Tony Wright went an incredible 266 hours without sleep back in 2007 and set a new record – only to see it broken by someone else just a month later. Wright spoke about his experience in a clip posted by the YouTube channel Sleep Gods, saying that an entirely different part of his brain was activated during his record attempt. "Basically, you're starving the rational mind, the egotistical mind of sleep, and it's battery is running down. And of course, it doesn't feel very good, it feels tired. Wright added: "But if you push beyond that, its ability to stay in charge starts to break down as well. And that's where you can start to get glimpses of access to the other side of the brain, the other self." Man Who Didn't Sleep For 11 Days Explains Sleep Deprivation www.youtube.com "I've spoken to a lot of people about this. Most people have recollections where they've been partying, or they've been working hard, and sure they get tired, but within that they get glimpses of something else.” He went on to say: "That kind of softness, or a more relaxed state - often more emotional, because again, there's more access to that emotional side of the brain. "Even feeling quite good, quite an altered state for brief windows, or getting a second wind even. You know, be really, really tired, no sleep, and then suddenly feeling fine for half an hour or an hour. "So all I really did, or what I was interested in, is making sense of that. And is it possible to exploit that and bring in combining techniques to tie the left side of the brain up, which initially doesn't feel great, but the reward on the other side of that makes it worth the effort."

What is Mercury in retrograde and why do so many people believe it impacts their lives?
What is Mercury in retrograde and why do so many people believe it impacts their lives?
Having a bad day? Mercury in retrograde. Broken your phone this morning? Mercury in retrograde. Had a sudden and unexpected breakup? Mercury in retrograde. It only takes a quick swipe through social media to see this cosmic event taking the blame for pretty much everything – and according to the age-old astrological theory, we are all influenced by its effects. Astrologers have been examining Mercury retrograde for thousands of years, but it wasn't until 2010 when Google searches started to spike. Now, with the help of Instagram and the drive towards self-care and mindfulness, interest in astrology has heightened to a whole new level. While Mercury retrograde is far too often viewed as a negative thing, it is also said to be the perfect time for self-reflection and growth. Laura Hayes, certified astrologer and founder of the online astrology community, @astrohuns, spoke with Indy100 to break down this astrological phenomenon. Sign up to our free Indy100 weekly newsletter What does Mercury retrograde mean? To put it simply, Mercury retrograde occurs when the planet Mercury – which takes 88 days to orbit the Sun, as opposed to Earth's 365 – appears to go backwards in its orbit. In Astrology, Mercury – named after the Roman deity who served as a messenger to the gods – is the planet of communication and the mind. Hayes explained: "Its placement in your birth chart affects how you think and communicate. Additionally, Mercury's transits at any given time will also have an impact on our thoughts and way of communicating." How long does it last? It tends to last around three to four weeks a time. However, there is also a "shadow period" – or retroshade – before and after Mercury Retrograde. This can apparently make things "a little rocky." "This Retroshade period lasts about 2-3 weeks and is almost like a diluted form of the retrograde itself," Hayes said. "Therefore, you may begin to feel the effects of Mercury retrograde a few weeks before it begins and still feel its lingering effects for a few weeks afterwards." How can it 'impact your life'? Astrologically speaking, when Mercury is in retrograde, the areas of life associated with the planet are said to be affected. "You are said to have verbal communication difficulties at this time, causing you to mishear someone or say the wrong thing, leading to arguments and misunderstandings," Hayes explained. People can find themselves "stumbling over their words, saying the wrong thing, or struggling to think coherently altogether." "Phones can lose signal; steamy texts to bae get sent to your boss instead, or your laptop breaks down when you're in the middle of writing your memoirs," she added. "Travel is another area that gets messed up during Mercury Retrograde, so be careful on the road and make sure to double-check flight details before you book." What can people do to deal with said 'effects'? According to KJ Atlas, consulting astrologer, writer, and artist of the human aura, you shouldn't put your life on hold purely because Mercury is retrograde. Instead, she says it is a time to significantly slow down. "You're more likely to make mistakes during this period, but if you listen to the call to take it easy, spend more time in self-care, go out less, and prioritize your mental and physical health, you'll be just fine," she explained. "If you need to sign contracts, purchase something significant, or have a deep talk, just do so mindfully and do your due diligence." Atlas acknowledged one positive rule of thumb: People are encouraged to do anything with the prefix 're'. "If you’re in a situation that you don’t enjoy, you can use this period for reevaluation or rekindling, but wait to take action until the cycle has ended. This includes the pre and post shadow periods. "People often jump right back into things that might be warnings during Mercury retrograde on the day that it’s technically over, but it’s good practice to wait a few days." When does Mercury retrograde occur? Mercury retrograde occurs three to four times per year. It tends to occur roughly around the same time each year. The dates* for this year are: January 14th - February 4th May 10th - June 3rd September 10th - October 2nd December 29th - January 18th (2023) *dates based on GMT, so they may vary slightly in other time zones. It's worth noting that astrology is not the same thing as astronomy. Astrology is a belief system that the stars and planets allow us to 'read a person', predict the future or have the ability to alter our daily lives, as above. Astrology can be important to some cultures, but it is not based on scientific evidence. Astronomy, however, is backed by data. David J. Helfand, Professor of Astronomy and Columbia University Chair, slammed the astrological theory as "arrant nonsense." Helfand explained that the retrograde motion of Mercury is a "simple consequence of the fact that we observe the sky from a moving platform we call Earth as it orbits the Sun. The other planets also orbit the Sun, all in the same direction." "The apparent motion of any planet as observed from Earth is a combination of the orbit of the planet and the orbit of Earth," he added. "Simple geometry shows that roughly three times a year (for Mercury – less often for other planets on longer orbits), these combined motions give the Earth-bound observer the illusion that the other planet has reversed its direction of motion compared to the background stars." He stated that the orbit of Mercury is governed by laws of gravity and is completely unchanged, which has "been well-understood for over 400 years – it's hardly a new idea." "But apparently, some people prefer 2000-year-old views of the world in which the planets govern their lives – no need to take any personal responsibility then, is there?" "In fact, the gravitational force of Mercury on an Earth-bound you is less than the force of your dog on you when you pat him or her on the head," Helfand explained. "Indeed, patting your dog on its head is likely to have a positive influence on your mood. Maybe people should try that instead of contemplating arrant nonsense about the planets."

Video of GoFast UFO resurfaces after being mentioned in NASA report
Video of GoFast UFO resurfaces after being mentioned in NASA report
NASA lifted the lid on its unidentified anomalous phenomena study on Thursday (14 September) which aimed to identify "how data gathered by civilian government entities, commercial data, and data from other sources can potentially be analysed to shed light on UAPs." While the report was "not a review or assessment of previous unidentifiable observations," the briefing prompted a video of 'GoFast UFO' to resurface. The clip from 2014 was released by the pilots "to clear up any misconceptions by the public on whether or not the footage that has been circulating was real or whether or not there is more to the videos." The statement on the Department of Defense further went on to say at the time: "After a thorough review, the department has determined that the authorized release of these unclassified videos does not reveal any sensitive capabilities or systems, and does not impinge on any subsequent investigations of military air space incursions by unidentified aerial phenomena." The clip also got a mention in the recent 36-page report, published on the NASA website. "A well-known UAP event is the “GoFast” video, recorded by navy aviators from the USS Theodore Roosevelt," it read. @uapbrand GOFAST UAP - better known as the 'Tic Tac' UFO. 🛸 #UAP #UnidentifiedAerialPhenomena #UAPs #OVNI #OVNIs #UFO #UFOs #UFOvideo #UFOvideos "A still frame from this video is shown in the Figure below, where the infrared camera has locked onto a small object in the center. The video gives an impression of an object skimming above the ocean at a great velocity. But analysis of the numerical information on the display reveals a less extraordinary interpretation." Elsewhere, while the report disclaimed the galaxy "does not stop at the outskirts of the solar system," it stressed there is "no reason to conclude" that UFO sightings are alien. "Many of NASA's science missions are, at least in part, focused on answering the question of whether life exists beyond Earth," it read. "Those investigations include missions looking for biosignatures, perhaps on Mars or the icy moons orbiting Jupiter and Saturn - as well as farther afield, in the ratios of molecules present in exoplanet atmospheres. "Searching for signs of alien technology is a natural extension of those investigations." It added: "If we recognise the plausibility of any of these, then we should recognise that all are at least plausible."

Study discovers vast numbers of women experience mental health issues because of period pain
Study discovers vast numbers of women experience mental health issues because of period pain
A study has shown that millions of women and girls experience debilitating periods, that even cause mental health problems. A survey of 3,000 women and girls in the UK aged 16 to 40 for the Wellbeing of Women charity found that 86 per cent had had mental health problems, such as depression, anxiety and mood changes, in relation to their period, Meanwhile, of those surveyed, 96 per cent had experienced period pain, with 59 per cent saying their pain was severe. 91 per cent had experienced heavy periods, with 49 per cent saying their bleeding was severe. Even though these are common symptoms in women and girls with gynaecological conditions such as endometriosis, adenomyosis, fibroids and polycystic ovary syndrome, the report found that 51 per cent of respondents felt their healthcare professional had failed to take their problems seriously, and 82 per cent said they needed better access to accurate information on period problems. A further one-third never seek medical help, and more than half say their symptoms are not taken seriously, despite other symptoms including pain, heavy bleeding and irregular cycles. Prof Dame Lesley Regan, the chair of Wellbeing of Women, said: “It’s simply unacceptable that anyone is expected to suffer with period symptoms that disrupt their lives, including taking time off school, work, or their caring responsibilities, all of which may result in avoidable mental health problems. “Periods should not affect women’s lives in this way. If they do, it can be a sign of a gynaecological condition that requires attention and ongoing support – not dismissal.” Wellbeing of Women has launched its “Just a Period” campaign, which Regan said aims to address “the many years of medical bias, neglect and stigma in women’s health”. This includes tips on how to get the most out of seeing your GP and what women should do if they feel they have been dismissed by health professionals. Responding to the findings, Dr Ranee Thakar, the president of the Royal College of Obstetricians and Gynaecologists, said: “All too often women are living with debilitating symptoms, waiting to receive support or treatment for far longer than they should. “Access to high-quality information and support about periods, gynaecological conditions and their symptoms is vital to ensuring that women and girls get the help that they need at the right time.” Caroline Nokes, the Conservative MP and chair of the women and equalities committee, which is conducting an inquiry into reproductive and gynaecological health, said: “There is a terrible phrase: ‘Well, it’s just a period, why are you making a fuss about that? Can’t you just get on with it?’ Yet many women and girls are experiencing horrendous period symptoms and gynaecological conditions. Endometriosis alone affects 1.5 million women in the UK and costs the economy £8.2bn. Now is the time for change.” Anneliese Dodds, the shadow secretary of state for women and equalities, said: “Over the past few years, we have opened up the conversation around the menopause, and now we need to see this change with periods as well.” Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.

'Earthquake lights' video seen moments before Morocco tragedy fuel age-old theory
'Earthquake lights' video seen moments before Morocco tragedy fuel age-old theory
With the tragedy and horror wreaked in Morocco last week, it's unsurprising that people’s focus hasn’t been on the skies. And yet, Friday’s devastating earthquake, has also sparked renewed interest in a mysterious aerial phenomenon. Footage shared to social media just moments before the 6.8-magnitude tremor struck the High Atlas mountains appears to show blinding lights flashing across the sky. Experts have suggested that the jaw-dropping sight is evidence of an enigmatic natural occurrence called “earthquake lights”. Reports of these bright flashes go back centuries. And yet, very little is known about them, to the point that scientists aren’t even sure they’re real. Indeed, some experts have concluded that there isn’t sufficient proof to support their existence, the United States Geological Survey notes. Nevertheless, “people have wondered about them forever," Karen Daniels, a physicist at North Carolina State University, told the New York Times. "It's one of those persistent mysteries that hang around and never quite get nailed." The issue with studying earthquake lights is that since earthquakes are impossible to predict, so are any preceding celestial pyrotechnics. Not knowing when or where they will occur means researchers can’t preemptively install the necessary equipment needed to detect them. Essentially, the only evidence we have comes from eyewitness accounts and, more recently, video recordings. And there is an abundance of the former, with a 2014 study noting that aerial luminous phenomena were reported in relation to 65 earthquakes which occurred in Europe and America over a period of 200 years. These descriptions of earthquake lights vary in their details, with some recalling on-and-of lightning-style flashes, and others minutes-long glows of different colours. “All of these have been reported by observers,” John Ebel, a seismologist at Boston Collegel told the NYT. “Which ones are actually true, and which ones are products of their imagination, we can’t really say.” One theory behind the formation of earthquake lights is that they are the result of friction between tectonic plates generating electricity. However, most experts are unconvinced by this hypothesis, including Dr Daniels. She told the NYT: “Rock on rock is not a situation where people have been able to generate large charge separation. And so it just doesn’t seem like a very good explanation for what people see.” Other scientists have suggested electrical arcing from power lines shaken by earthquakes could be responsible for the sky flares. But Dr Daniels acknowledged it’s still possible that there’s no link at all between the lights and tectonic events. “We’re comforted by things that we can understand, and we’re scared by things we don’t,” she pointed out. “I think that’s part of the reason we’re so fascinated by this phenomenon.” Sign up for our free Indy100 weekly newsletter Have your say in our news democracy.

Scientists discover new Black holes that could be creeping up on Earth
Scientists discover new Black holes that could be creeping up on Earth
A new study has revealed that black holes could be lurking much closer to Earth than anticipated. A black hole in space is when "gravity pulls so much that even light can not get out," NASA explains. "The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying." Due to no light being present, they are invisible. Only special tools can pick up on them. There are said to be around 10 million to 1 billion mass black holes in the Milky Way, according to Science Alert. However, astrologers only know of about 20 of them. Now, a recent study has revealed that they could be a lot closer to Earth than previously thought after investigating the Hyades cluster, "a group of stars located 150 light-years away". In a statement, astrophysicist Stefano Torniamenti of the University of Padua explained: "Our simulations can only simultaneously match the mass and size of the Hyades if some black holes are present at the centre of the cluster today (or until recently). The Hyades with hundreds of stars is said to be approximately 625 million years old. Due to its packed environment, "higher rates of collisions and mergers" are expected. At 153 light-years away, it is considered the closest star cluster to Earth. Researchers were able to observe two or three black holes in the Hyades, which are either still present or ejected less than 150 million years ago and hovering around the outskirts. "This observation helps us understand how the presence of black holes affects the evolution of star clusters and how star clusters in turn contribute to gravitational wave sources," Professor Mark Gieles of the University of Barcelona said.
