It’s well known that all humans alive today can be traced back to a common ancestor but a study may have found where that ancestor originates. Researchers at the University of Oxford’s Big Data Institute mapped the entirety of genetic relationships among humans to create the largest human family tree ever. By combining modern and ancient human genomes data from eight different databases, the researchers were able to create a massive family tree. This allowed them to see how a person’s genetic sequence relates to another using the points of the genome. Sign up for our free Indy100 weekly newsletter “Essentially, we are reconstructing the genomes of our ancestors and using them to form a vast network of relationships,” Lead author Dr Anthony Wilder Wohns said. “We can then estimate when and where these ancestors lived.” Where they lived? Sudan, Africa. Dr Wohns told Reuters, "The very earliest ancestors we identify trace back in time to a geographic location that is in modern Sudan. “These ancestors lived up to and over 1 million years ago—which is much older than current estimates for the age of Homo sapiens—250,000 to 300,000 years ago. So bits of our genome have been inherited from individuals who we wouldn’t recognize as modern humans," Dr Wohns said. Researchers used 3,609 individual genome sequences from 215 populations and samples that ranged from 1,000s to over 100,000 years. By using a new method to compile the data, algorithms were able to predict where common ancestors were in evolutionary trees to explain some patterns of genetic variation. The results were a network of almost 27 million ancestors. “The power of our approach is that it makes very few assumptions about the underlying data and can also include both modern and ancient DNA samples,” Dr Wohns says. Not only does the data help us understand human geology better but the new method could help in other research, like medicine. “The underlying method could have widespread applications in medical research, for instance identifying genetic predictors of disease risk," Dr Wohns added.

Scientists have managed to simulate their very own black hole in their lab and witnessed how it began to glow. The black hole event horizon was created by a team of physicists from the University of Amsterdam, who used a chain of atoms in a single file to gain further understanding about the behaviour of a black hole. Its creation managed to prove Stephen Hawking's theory from 1974 where the black hole emitted a rare form of radiation. Sign up to our free Indy100 weekly newsletter They studied the properties of Hawking radiation through the creation of a black hole analog in the lab. According to Science Alert, Hawking radiation happens when "particles born from disturbances in the quantum fluctuations caused by the black hole's break in spacetime." The fact that the radiation exhibits a glow itself is in a strange space anomaly, as the event horizon of a black hole is supposed to be where neither light nor matter is able to get out. We all learn about the strength of a black hole in science class – and how we would all be inevitably sucked in as a result. This is possible due to its density within a certain range of the centre, so even an attempt at travelling beyond light speed (or any velocity in the universe for the matter) would not make this unavoidable. The fake black hole event also caused a rise in temperature that matched theoretical expectations of an equivalent black hole system, - but only when part of the chain extended beyond the event horizon, Science Alert reported. As a result, it is believed perhaps this entanglement of particles that straddle the event horizon plays a big role in generating Hawking radiation. Under simulations that began by mimicking spacetime thought of as "flat," scientists say the radiation was only thermal for a certain range of 'hop amplitudes'. So there may be certain situations where Hawking radiation can emit thermally - and could only be the case where gravity causes a change in the warp of space-time. "This can open a venue for exploring fundamental quantum-mechanical aspects alongside gravity and curved spacetimes in various condensed matter settings," the scientists wrote in their paper published by Physical Review Research.

It’s footage that’s fascinated conspiracy theorists for decades, but artificial intelligence is making people look at the most famous alleged sighting of ‘Bigfoot’ in a new light. Back in 1967, a clip known as the Patterson–Gimlin film claimed to show the mysterious creature, also known as ‘sasquatch’, walking through the Six Rivers National Forest in California. Roger Patterson and Robert Gimlin shot a figure moving in the woods in low resolution footage and claimed that they had discovered proof of the urban legend known as Bigfoot. The pair claimed at the time they tracked the figure before setting up filming equipment and capturing grainy video which looks briefly at the camera. Sign up to our new free Indy100 weekly newsletter While it was dismissed by the scientific community at the time and seen as a hoax by most people, it’s been poured over by conspiracy theorists ever since. It’s been analysed many times since, but new artificial intelligence has been used to present a clearer image than ever before. The clip has been stabilised and de-grained, and the results are clearer than ever. Social media user Rowan Cheung often shares the “latest developments in the world of artificial intelligence” and he posted the footage. Just as many conspiracists will have feared, the newly treated footage proves that it was clearly just a guy in a gorilla costume all along. Yes, we all knew that already, but this newly developed footage offers the clearest look at an infamous piece of footage yet – and people were quick to react on social media. “Nooppe! thats just a dude on his way to a costume party!” one wrote. Another said: “This is the ai work we needed.” One more said: “Just some bro out for a stroll.” “So it’s a dude in a gorilla suit?” a comment read. Artificial intelligence, it seems, has the power to surprise us when we least expect it. It’s not the first time ‘Bigfoot’ has made headlines this year, after people claimed to have discovered a sighting via Google Maps. Have your say in our news democracy.

The Moon has been a subject of awe and fascination for millennia, with its shape-shifting powers and enigmatic dark side. And though it’s the one celestial body on which man has taken (small) steps, we still have big leaps to go in understanding its potential and uncovering its secrets. However, one hidden feature of the Moon has been unearthed by scientists and it’s very, very big, and very, very heavy. Buried beneath its South Pole-Aitken basin – one of the largest preserved craters in the Solar System – is a structure which weighs at least 2.18 billion kilogrammes and measures more than 300km (186 miles) in depth and 2,000km (1,243 miles) in length. Sign up for our free Indy100 weekly newsletter The researchers who made the discovery, all based in the US, posited that the “anomaly” could be made out of metal from the core of an asteroid or oxides from the crystallisation of a magma ocean. "One of the explanations of this extra mass is that the metal from the asteroid that formed this crater is still embedded in the Moon's mantle,” lead author Peter B. James, from Houston’s Baylor University, said in a statement shared with IFLScience. Illustrating just how gigantic this thing is, he went on: "Imagine taking a pile of metal five times larger than the Big Island of Hawaii and burying it underground. That's roughly how much unexpected mass we detected.” The groundbreaking finding was made thanks to NASA’s Gravity Recovery and Interior Laboratory (GRAIL) mission, which measures changes in the Moon’s gravitational field. Data collected by GRAIL can then be used to study the internal composition of our cratered companion. The South Pole-Aitken Basin has been at the centre of numerous investigations because of just how unique it is. The region offers clues both on the interior composition of our closest satellite and its history, and who knows what other mysteries it holds... Have your say in our news democracy.
