It feels like every day there’s a science story that comes along ready to blow our tiny minds, and today is no exception. A series of ancient interconnected cities have been discovered in the remote El Mirador jungle Guatemala, and it’s changing our entire understanding of the ancient civilisation. More than 400 settlements have been uncovered with some dating back as far as 1,000 BC. They’re linked by roads too, and it’s led them to be described as “the first freeway system in the world”. Sign up to our free Indy100 weekly newsletter Richard Hansen, a research professor at the University of Idaho, is an expert on the project and he’d called the findings a “game-changer”. It was previously thought that the Mayan peoples were nomadic, but these cities have changed the scientific community’s understanding. Speaking to the Washington Post, Hansen said: "We now know that the Preclassic period was one of extraordinary complexity and architectural sophistication, with some of the largest buildings in world history being constructed during this time.” On top of the 110 miles of interconnected roads, the discoveries also showed evidence of organised agriculture and even hydraulic systems. The findings are the result of work which first began in 2015, which saw lidar technology uncovered signs of ancient structures below the surface. Archaeologist Enrique Hernández, from San Carlos University said about the findings: “Now there are more than 900 [settlements]… We [couldn’t] see that before. It was impossible,” he said.

Scientists have been peering into the depths of space, looking right back at the early days of the universe, and they’ve found something very interesting indeed. Researchers using the James Webb Space Telescope have come across a discovery that indicates some of the very earliest stars to ever form in the universe were staggering in scale, measuring 10,000 times bigger than the Sun. "Today, thanks to the data collected by the James-Webb Space Telescope, we believe we have found a first clue of the presence of these extraordinary stars," says astrophysicist Corinne Charbonnel of the University of Geneva in Switzerland, in research published in Astronomy & Astrophysics. These features are huge collections of between 100,000 and 1 million stars known as globular clusters, which all feature similar properties. Scientists estimate that they were all formed at the same time. Sign up to our free Indy100 weekly newsletter They’re remnants of the ancient universe and have been described by researchers as "fossils". The cores of these stars are much hotter than those we see in stars today, and scientists suggest it could be down to an excess of hydrogen burning at high temperatures. It’s thought that smaller stars collided with the supermassive stars and relished their energy. However, now most of these global clusters are approaching the very end of their life spans. "Globular clusters are between 10 and 13 billion years old, whereas the maximum lifespan of superstars is two million years," said Mark Gieles, previously at the University of Surrey but now at the University of Barcelona, back in 2018. "They therefore disappeared very early from the clusters that are currently observable. Only indirect traces remain." The researcher states: "If the supermassive star scenario can be firmed up by future studies, this would provide an important step for our understanding of globular clusters and for the formation of supermassive stars in general, with numerous important implications.” Have your say in our news democracy.

Captcha is trying to get people using Discord a to identify objects that do not exist. As reported by Vice, multiple people using the platform are being shown a “Yoko,” which looks like a mix between a snail and a yoyo, and has been generated by AI, or other AI generated images like puzzle cubes. Meanwhile, two months ago, a Redditor noticed Discord was asking it to distinguish AI generated soccer players amidst a group of pictures of people playing hockey and golf. Sign up to our free Indy100 weekly newsletter Others have complained that images being generated are just 'awful.' Discord’s captchas are run by a company called hCaptcha. “The technology that generates these prompts is proprietary to our third-party partner and Discord does not directly determine what is presented to users,” Discord told Motherboard. “While most hCaptcha interactions do not result in a visual challenge, many variants are used at any given time. “This particular question was a brief test seen by a small number of people, but the sheer scale of hCaptcha (hundreds of millions of users) means that when even a few folks are surprised by a challenge this often produces some tweets.” Have your say in our news democracy.

Scientists have been left baffled by the discovery of the wreck of a 2,000-year-old “computer” that is amazingly complex. The Antikythera mechanism – an astronomical calendar – has been dubbed “‘the first computer” and has baffled scientists for generations after it was first discovered inside a Greek shipwreck in 1901. The device is a hand-powered time-keeping instrument that used a wing-up system to track the sun, moon and planets’ celestial time. It also worked as a calendar, tracking the phases of the Moon and the timing of eclipses. Despite sounding relatively simple, the mechanism was actually ahead of its time, being more technically sophisticated than any other tool that was invented over the next 1,000 years. In its current condition, the mechanism is in 82 separate fragments with only a third of its original structure remaining, including 30 corroded bronze gearwheels. Sign up to our free Indy100 weekly newsletter Research into the device from experts at University College London involved 3D computer modelling and helped them solve the mystery of how the device worked, revealing a “creation of genius”. Adam Wojcik, a materials scientist at UCL said at the time: “We believe that our reconstruction fits all the evidence that scientists have gleaned from the extant remains to date.” They theorised that the device tracked the movement of the sun, moon and planets on concentric rings, as the ancient Greeks believed that the sun and planets revolved around Earth, rather than the sun. The researchers explained in Scientific Reports: “Solving this complex 3D puzzle reveals a creation of genius—combining cycles from Babylonian astronomy, mathematics from Plato’s Academy and ancient Greek astronomical theories.” Have your say in our news democracy.

One unlucky guy lived out every man’s worst nightmare recently, after suffering a “triple penis fracture”. A man from Tanzania was hospitalised after hearing his penis “snap” during sex. Details of the grisly injury were recorded in the International Journal of Surgery Case Reports. The “snap” happened “when the penis slipped out, lost the way” and struck his female partner “as he was trying to reinsert it”. It’s enough to make anyone wince, and the extent of his injury was revealed after he took himself to hospital. Sign up to our free Indy100 weekly newsletter Doctors took a look and found the penis to be severely swollen and covered in blood. They diagnosed him with having a “fractured” penis, which refers to a rupture in the fibrous connective tissue, called the tunica albuginea. Not only that, but an MRI scan also showed that there were three clear points of injury along the tunica albugine, with the main “fractures” in the erectile tissues known as the corpora cavernosa and the corpus spongiosum. The man was taken into surgery before being discharged three days later. He also had a catheter fitted in his urethra which was removed after three weeks. “He was seen at the clinic six months post-operative where he reported having resumed his sexual life with no any difficulties and the penile shaft looked OK,” his doctors said in the report. It sounds like all kinds of pain, and it’s an injury that is becoming more and more common. The NHS revealed stats in 2020 that showed 38 percent rise in such injuries from 2014 to 2020. Doctors speculated at the time that it could be down to pornography viewing habits leading to more couples trying unusual sexual positions, as well as an increase in the use of Viagra.

Saturn’s rings might disappear pretty soon astronomically speaking, according to new research. A new analysis of data captured by NASA’s Cassini mission, which orbited the planet between 2004 and 2017, has revealed new insights into when the seven rings were formed and how long they might last. During Cassini’s Grand Finale, when the spacecraft completed 22 orbits in which it passed between Saturn and its rings, the researchers observed that the rings were losing many tons of mass per second, which means the rings will only be around another few hundred million years at most. “We have shown that massive rings like Saturn’s do not last long,” said Paul Estrada, research scientist at NASA’s Ames Research Center in Mountain View, California, and a coauthor of the studies, in a statement. “One can speculate that the relatively puny rings around the other ice and gas giants in our solar system are leftover remnants of rings that were once massive like Saturn’s. Maybe some time in the not-so-distant future, astronomically speaking, after Saturn’s rings are ground down, they will look more like the sparse rings of Uranus.” Sign up to our free Indy100 weekly newsletter Saturn’s rings are made mostly of ice but have a small amount of rocky dust created by broken asteroid fragments and micrometeoroids colliding with the rings. The research also found that the rings appeared long after Saturn’s initial formation, and were still forming when dinosaurs roamed the Earth. “Our inescapable conclusion is that Saturn’s rings must be relatively young by astronomical standards, just a few hundred million years old,” said Richard Durisen, professor emeritus of astronomy at Indiana University Bloomington and lead author of the studies in a statement. “If you look at Saturn’s satellite system, there are other hints that something dramatic happened there in the last few hundred million years. If Saturn’s rings are not as old as the planet, that means something happened in order to form their incredible structure, and that is very exciting to study.” Have your say in our news democracy.

Elon Musk’s brain chip company Neuralink said on Thursday that it now has regulatory approval in the US to test its implants in human subjects. Neuralink has been building chips to be implanted into the skull for a brain-computer interface, claiming their development has the potential to help restore vision in the blind, and even help paralysed people walk again. While Mr Musk has said on several occasions since 2019 that the company is ready to go for experiments in humans to treat paralysis and blindness, the US Food and Drug Administration (FDA) had however rejected proposals by the company to begin human clinical trials. For instance, in early 2022, when Neuralink applied for human testing, the FDA rejected the proposal saying there were “dozens of issues the company must address”. These issues flagged by the FDA included the use of lithium batteries in Neuralink’s device and the likelihood of the implant’s wires interfering with the brain. The federal agency also expressed concerns about whether the firm’s implants can be removed without causing brain damage. Neuralink has also come under the scanner of at least one US government probe after animal rights watchdogs accused the firm of “inadequate care” of its research monkeys. Reuters previously reported that the brain chip company killed about 1,500 animals, including over 280 sheep, pigs and monkeys since 2018. The US Department of Agriculture also began investigating Neuralink’s potential violations of the Animal Welfare Act. Responding to the animal abuse complaints, the company said in a blogpost that it was “absolutely committed to working with animals in the most humane and ethical way possible”. “The use of every animal was extensively planned and considered to balance scientific discovery with the ethical use of animals,” it said. In a tweet in November last year, Mr Musk said he was confident that Neuralink’s device was “ready for humans”, adding that the timing for beginning human trials was a “function of working through the FDA approval process”. “We want to be extremely careful and certain that it will work well before putting a device into a human but we’ve submitted I think most of our paperwork to the FDA and probably in about six months we should be able to upload Neuralink in a human,” the Tesla and SpaceX chief said. On Thursday, the company said it has finally received approval from the federal agency to begin trials in humans. “We are excited to share that we have received the FDA’s approval to launch our first-in-human clinical study!” the brain chip company said. The FDA approval “represents an important first step that will one day allow our technology to help many people”, Neuralink said, adding that it would soon announce more information on the recruitment of people for clinical trials. FDA hasn’t immediately responded to The Independent‘s queries on the Neuralink approval claim. Read More What is superintelligence?

Earth has received the first ever ‘alien message’ after a simulation of what extraterrestrial contact could look like was sent out by scientists. The SETI Institute produced the simulation of a radio wave from a Mars orbiter and gave hint of how alien contact would be received. The exercise was conducted to prepare experts for the “profoundly transformational experience for all humankind”. The signal was successfully decoded after taking just 16 minutes to travel through space and be picked up by telescopes on Earth. Sign up to our free Indy100 weekly newsletter It all took place as part of the A Sign in Space project led by Daniela dePaulis, who said during the live-streamed event: “It was very real. This is not the first time we have received a signal from TGO [ExoMars Trace Gas Orbiter], but this one is a real message.” The signal had to be decoded, as it couldn’t be heard on Earth without being altered. Victoria Catlett is the GBO software engineer and she explained: “A radio signal is not inherently sound, but a light wave. “When we receive it with something like a car radio, that light wave gets translated into the up and down movement in the speaker - and that is what you hear.” Of course, there’s no evidence that aliens exist at this point, but it’s good to know that we’re prepared. It comes after it was revealed that aliens could be mapping out the planet via the signals mobiles are emitting. It’s all to do with the radio transmission towers which are key to millions of people communicating around the world. These towers are constantly pumping out microwave signals as we call and message one another, and they’re found across a huge area of the Earth’s surface. Have your say in our news democracy.
