Omegle, a popular website used to video chat with strangers, is shutting down after almost 15 years. The closure comes amid increasing criticism that the site endangered its users, with reports of child sexual abuse and other crime on the platform. Omegle allowed users to sign up and then be launched into a video chat with another stranger using the site. The two could chat for as long as they wished – until they ended that conversation and embarked on a new one. The app was launched in 2009, and became popular almost straight away. Its founder said that its popularity was a result of “meeting new people being a basic human need”. Quickly, however, it became known for explicit and other criminal content. Leif K-Brooks, the company’s founder, admitted that Omegle had been misused, “including to commit unspeakably heinous crimes”. The site attempted to introduce new features to stop that misuse, such as “monitored chats” that would allow moderators to try and stop criminals using the site. But they did not work, and the site continued to receive criticism for its lack of safety. Now Mr K-Brooks has said that the criticism has become too much, and Omegle will shut down. The intensity of the fight over use of the site had forced him to decide to shut it down, he said, and it will stop working straight away. “As much as I wish circumstances were different, the stress and expense of this fight – coupled with the existing stress and expense of operating Omegle, and fighting its misuse – are simply too much. Operating Omegle is no longer sustainable, financially nor psychologically. Frankly, I don’t want to have a heart attack in my 30s,” wrote Leif K-Brooks, who has run the website since founding it. Omegle saw a huge surge in popularity during the pandemic, as people not only flocked to the site but recorded their interactions and shared them on social media. But that popularity also brought more awareness of the problems on the site, and increased criticism of it. Mr K-Brooks acknowledged that criticism. But he also suggested that at least some of it was in bad faith, and that it was intended to force the site to shut down. “In recent years, it seems like the whole world has become more ornery. Maybe that has something to do with the pandemic, or with political disagreements. Whatever the reason, people have become faster to attack, and slower to recognize each other’s shared humanity. One aspect of this has been a constant barrage of attacks on communication services, Omegle included, based on the behavior of a malicious subset of users,” he wrote. He said that the site had been shut down on the basis of “fear”. “If something as simple as meeting random new people is forbidden, what’s next?”, he wrote, comparing the end of Omegle to “shutting down Central Park because crime occurs there – or perhaps more provocatively, destroying the universe because it contains evil”. The decision to shut down Omegle comes amid increasing concern about regulation of the internet and how best to protect its users. It comes just days after the introduction of the UK’s Online Safety Act, for instance, which aims to hold platforms to account for crimes on their platform, including online grooming.

A 200 million-year-old parasite has been discovered in fossilised poo, in the latest not-at-all-scary instance of scientists unearthing a species which blighted the Earth in ancient times. Researchers found that the earliest predators on the planet were infested with roundworm, also known as nematodes, among multiple other parasites. The fossilised poo, which is known to palaeontologists as coprolite, is thought to belong to a type of semi-aquatic phytosaur, which was a crocodile-like predator. Sign up to our free Indy100 weekly newsletter It comes weeks after another team revived a prehistoric worm – the catchily named Panagrolaimus kolymaensis – which was found dormant in the Siberian permafrost in a state of “cryptobiosis”. The latest study saw researchers from Mahasarakham University, Thailand, analyse a three-inch-long portion of ancient poo and discover five types of parasitic remnants. The group sliced open the parasitic egg fossils with a diamond saw using a “standard thin section method,” their report said. The ultra-thin slices allowed the palaeontologists to look at cross-sections of the ancient infectious microbes under a microscope. One was identified as a nematode worm egg, while the others are thought to be either more eggs, protozoan cysts or spores from moss and ferns. While modern parasites are often an important part of ecosystems, it is usually more difficult to work out what their ancient equivalents did, because there are so few examples in the fossil record. The creatures often inhabited the soft tissues of their hosts, but are rarely preserved as fossils, making the latest discovery all-the-more significant. This fossilised late Triassic-era coprolite (the poo), was shielded from the elements in the Huai Hin Lat geological formation in Thailand, which is over 200 million years old. It was found by local villagers, according to the study's lead author, paleontologist Thanit Nonsrirach. “The peculiar appearance of these findings intrigued the villagers, who considered them potentially auspicious and capable of bestowing good luck if repurposed as talismans,” Nonsrirach told news outlet Inverse. “In 2010, our team received word of this discovery and embarked on a field expedition, guiding the villagers to the actual fossil site.” The discovery is the first record of parasites in a terrestrial vertebrate host from the late Triassic period in Asia, and provides a rare look at the life of an ancient creature that was infected by multiple species. This discovery also adds to the few known examples of nematode eggs preserved within the coprolites of Mesozoic animals. “Parasites of several species, including Ascaridida (roundworm) eggs were found in a coprolite, probably produced by a crocodile-like reptile and possibly a phytosaur,” said Nonsrirach, who works at Mahasarakham University's Palaeontological Research and Education Center. “This is therefore the first discovery of Ascaridida eggs and evidence of multi-infection in a host assignable to the Crurotarsi from the Late Triassic of Asia. “Coprolite is a significant palaeontological treasure trove, containing several undiscovered fossils and expanding our understanding of ancient ecosystems and food chains. “These findings are therefore a significant contribution to scientific understanding of the distribution and ecology of parasites of the distant past.” Have your say in our news democracy.

Scientists have built a breakthrough device that can clean dirty water and turn it into clean hydrogen fuel. The “simple” device could be used in areas without resources or places where people live off the grid. And it is just one example of the many solutions that will be required to respond to pollution and give people access to both clean fuel and water, the researchers behind it say. The system is inspired by photosynthesis, the process where plants turn light into food. But previous versions of those “artificial leaves” have required clean water sources – whereas the new device can be used with polluted water and even produce clean drinking water at the same time. As such, scientists believe that it could help solve two problems at once: making green fuel and cleaning water so that it is ready to drink. “Bringing together solar fuels production and water purification in a single device is tricky,” said Chanon Pornrungroj from the University of Cambridge, the paper’s co-lead author. “Solar-driven water splitting, where water molecules are broken down into hydrogen and oxygen, need to start with totally pure water because any contaminants can poison the catalyst or cause unwanted chemical side-reactions.” The system uses a carbon mesh to absorb light and heat, creating water favour that is then turned into hydrogen for fuel by a photocatalyst. That carbon mesh also repels water, so that the system can float and its important parts can be kept from being damaged by water. The device is also able to harness more of the Sun’s energy than previous examples, which have used only a small portion of the spectrum of light. The new system has a white layer on top to absorb UV rays, with the rest being used lower down to vaporise the water. “This way, we’re making better use of the light – we get the vapour for hydrogen production, and the rest is water vapour,” said Dr Pornrungroj. “This way, we’re truly mimicking a real leaf, since we’ve now been able to incorporate the process of transpiration.” The researchers behind the breakthrough noted that the system was simple to make, and was especially able to deal with very polluted water. As such, it could be a key way of working towards a sustainable future, they said – even though it is just a proof of concept for now. “The climate crisis and issues around pollution and health are closely related, and developing an approach that could help address both would be a game-changer for so many people,” said Cambridge’s Erwin Reisner, who led the work. The device is described in a new paper, ‘Hybrid photothermal-photocatalyst sheets for solar-driven overall water splitting coupled to water purification’, published in Nature Water today.

A study of 150 stones dating back 1.4m years shows early humans were deliberately crafting spherical shapes – but nobody knows why. The Hebrew University of Jerusalem made findings after analysing the limestone balls which were unearthed in Ubeidiya, a dig site in Israel’s Jordan Rift Valley. Scientists have previously speculated that the stones, which were discovered in the 1960s and serve no discernable purpose, became round after being used as hammers. But the university’s team reconstructed the steps required to create the so-called spheroids and found they were part of a “preconceived goal to make a sphere”. The researchers used 3D analysis to retrace how they were made based on the markings and geometry of the spheroids. They concluded that the objects were intentionally “knapped”, the technique used to shape stone by hitting it with other objects. Antoine Muller, a researcher at the university’s Institute of Archaeology, said: “The main significance of the findings is that these spheroids from ‘Ubeidiya appear to be intentionally made, with the goal of achieving a sphere. “This suggests an appreciation of geometry and symmetry by hominins 1.4 million years ago.” Early humans clearly had some reason for making the balls, but what exactly that is remains a mystery. He said: “We still can’t be confident about what they were used for. A lot of work needs to be done to narrow down their functionality.” Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.

They may not be as stylish as a DeLorean or as sturdy as a blue police box, but wormholes in space could hold the key to real-life time travel – and a team of experts think they’ve figured out how. The trio of scientists delved deep into the laws of physics and discovered that it might be possible for humans to one day zip across galaxies in a matter of seconds, or journey through time itself. Now, this is all to do with the general theory of relativity and quantum physics, so don’t expect to get your head around it too easily. However, in their paper, Valeri P. Frolov and Andrei Zelnikov of Canada’s University of Alberta, and Pavel Krtouš of Prague’s Charles University proposed that a specific kind of wormhole would “inevitably” be “transformed into a time machine” if it was subject to particular conditions. Sign up for our free Indy100 weekly newsletter For the uninitiated, wormholes can be described as spacetimes in which a “kind of tunnel exists connecting distant parts in the universe”. The main problem with them is… they don’t actually exist. At least not in any tangible way. As Drs Eric Christian and Louis Barbier put it in an explainer for NASA: “Wormholes are allowed to exist in the math of ‘General Relativity’, which is our best description of the Universe. “Assuming that general relativity is correct, there may be wormholes. But no one has any idea how they would be created, and there is no evidence for anything like a wormhole in the observed Universe.” Still, numerous experts in the field of gravitation and general relativity have spent years or even decades working on them, including Stephen Hawking in his time. For their paper, Frolov, Krtouš, and Zelnikov explored what is known as a ring wormhole, which was first described in 2016 by theoretical physicist Gary Gibbons, of Cambridge University, and Mikhail Volkov of the University of Tours. Unlike the spherical contortions of spacetime we might attribute to black holes, the ring wormhole proposed by Gibbons and Volkov connects sections of the universe (or, indeed, different universes) which are generally described as “flat”, as ScienceAlert notes. Ring-shaped masses could potentially create some pretty remarkable distortions in what would otherwise be flat spacetime if you consider how their electrical and magnetic fields might interact. And so Frolov, Krtouš, and Zelnikov decided to consider two types of such wormholes: “a wormhole connecting to flat spaces; and a wormhole connecting two distant domains in the same space”. For the latter, they concluded that if a “massive thin shell” surrounded one of the mouths of the ring wormhole, a “closed timelike curve” would form. This, as the name suggests, would mean that any travelling object (or ray of light) would come back to the exact same point whence it began. In other words, you could travel in space and time and return to your point of departure. The most exciting aspect of ring wormholes, as the authors point out is that: “For the ring wormhole an observer passing through it moves in a flat (or practically flat spacetime), while in the case of ‘standard’ (spherical) wormholes he/she should pass a domain filled with the matter violating the null energy condition.” Even without knowing what the “null energy condition” is, you can appreciate that the first option sounds a lot simpler. Now, before you start calling yourself Marty McFly or making a list of all the past mistakes you’d like to correct, we should stress that we’re a long way off seeing the creation of a bonafide, buckle-your-seatbelt time machine. But at least, thanks to the efforts of experts like Frolov, Krtouš, and Zelnikov, we’re at least one step closer to going back in the future. Have your say in our news democracy.
