Twitter has been a powerful tool for social movements. But since Elon Musk acquired the platform last year, some organizers and digital media experts have been bracing for the impact that his controversial policy changes and mass layoffs may have on social activism.

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.

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.

Is there life on Mars? Well, according to new research, an alien crash landing there could explain puzzling new findings on the surface of the Red Planet. It comes after Nasa’s Curiosity Rover captured images of spiked protrusions on the surface back in April. The strange formations captured in the pictures seem to show a row of spikes and sharp angles emerging from rocks at the base of the Gale Crater, which is 154km long. The odd discovery has put scientists on high alert and it marks one of the most peculiar things ever recorded on the surface of Mars. Sign up to our free Indy100 weekly newsletter Astrobiologist Dr Nathalie Cabrol, who is from the NASA Ames Research Centre and Search for Extraterrestrial Intelligence (SETI) Institute, even said that it’s the “most bizarre” rock she’s seen in 20 years of studying the planet. The findings are so irregular, in fact, that experts cannot rule out the idea that they’re extraterrestrial in origin. “A fragment from an extraterrestrial or terrestrial spacecraft cannot be discounted with absolute certainty” the authors of new research published in the Journal of Astrobiology stated. The odd protrusions could be “sand spikes”, which form in certain sands as a result of strong earthquakes. Another theory posits that the formation could be debris from crashed spacecraft, and authors of the study have not ruled out that it could be the result of crafts launched by humans landing on the surface. "Given that possibly 10 or more craft have crashed upon the surface, coupled with the jettison of equipment associated with landing the rovers, it is possible the spikes and its substrate are human-made and consist of debris that fell onto the surface of Gale Crater," the paper reads. “Nevertheless, no debris field is evident and no evidence of any additional debris that may have originated on Earth. “Given its small size and that there are no known human-made analogs and no logical explanation as to what purpose these spikes may serve, it does not seem likely these specimens are the remnants of craft or equipment that fell into Gale Crater. One can only speculate about extraterrestrial origin." However, speaking to The Telegraph, Prof Richard Armstrong, of Aston University, Birmingham said: “There is no way of proving for certain what the spikes are but the balance of the evidence would suggest ‘sand spikes’ resulting from seismic activity on Mars.” Have your say in our news democracy.

Pokémon Sleep, a game in which players go to bed in real life to win, is rocketing up the App Store charts. The app is now sixth in Apple’s charts, suggesting that makers The Pokémon Company may have found a way to replicate some of the success of their previous hit Pokemon Go. To play the game, people download the app onto their iPhone – or use a separate, paid-for accessory that the company says can be used to track sleep as well as make it easier. Once that is done, users mostly play by going to sleep. When they wake up in the morning, they will receive information about their sleep patterns – how long they slept, what kind of sleep that was, and whether players made any noises during the night – and receive rewards of Pokémon that will be caught based on that data. The game has received some negative reviews: on the iOS App Store, one player called it “deeply flawed and predatory”, criticising the fact that tracking sleep with the iPhone app means sleeping with it and leaving the screen on. While players can use the Pokémon Go Plus +, which has been given a confusing name presumably to separate it from the existing Pokémon Go Plus, that costs $60. It also received a critical review in The Verge, which said that while it was “incredibly cute”, it came with some drawbacks, including the fact that it requires players to undertake dull tasks during the day and offered few meaningful ways to actually improve sleep. Nonetheless, the game appears to have proven incredibly successful on the iPhone’s App Store and Android’s Google Play Store, where it has been downloaded millions of times. The game comes amid a growing interest in the benefits of sleep, and the technology that can help promote it. Multiple wearables such as those made by Apple, Garmin and Whoop all track the sleeping habits of their wearers, and other companies have promoted cooling and massaging technologies that are aimed at helping people get more restful sleep.
