An artificial intelligence (AI) tool that can tell if social media users are too young to use apps like Instagram and TikTok has been developed by a UK tech start-up. Yoti's'Age Estimation' system -- which may well soon be rolled out across social media -- can tell how old users between 6–18 are to a 1.5-year margin of error. The software works by comparing the user's facial features as captured via device camera against millions of other images of Yoti digital ID app users of known age. Social media firms such as Facebook have long struggled with how to handle minimum age verification without requests for passport details, which many see as intrusive.

Hundreds of newly-discovered ancient ceremonial sites in Mexico reveal how the Mayans adopted a mysterious design trait from the older Olmec civilization more than 3,000 years ago, a study shows. Researchers have revealed that there are 478 ceremonial complexes that can't be seen with the human eye in modern-day southern Mexico, but can be detected with lidar scanning technology. The hundreds of ceremonial complexes are a combination of Maya and older Olmec sites, according to the study authors. Originating around 2600 BC, the Maya civilization thrived in Central America for nearly 3,000 years, reaching its height between AD 250 to 900. The Olmecs, meanwhile, were another Mesoamerican civilization who occupied the land earlier, from around 2,500 to 400 BC.

Japanese researchers have built a robot with brain-like neurons that were grown in the lab, in order to teach it to'think like us'. In experiments at the University of Tokyo, the compact robotic vehicle on wheels, small enough to fit in a person's palm, was placed in a simple maze. The robot was connected to a culture of brain neurons, also known as nerve cells, that were grown from living cells. When these artificial neurons were electrically stimulated, the machine successfully reached its goal – a black circular box. A neuron, also known as nerve cell, is an electrically excitable cell that takes up, processes and transmits information through electrical and chemical signals.

In 1996 Nasa and the White House made the explosive announcement that the rock contained traces of Martian bugs. The meteorite, catalogued as Allen Hills (ALH) 84001, crashed onto the frozen wastes of Antarctica 13,000 years ago and was recovered in 1984. Photographs were released showing elongated segmented objects that appeared strikingly lifelike.

Madagascar's critically endangered'singing' lemurs -- Indri indri -- have a natural ability to keep a beat, just like us humans do, a study has concluded. Researchers from the Max Planck Institute for Psycholinguistics and the University of Turin studied the songs of indri in the rainforests of the island country. They found that the lemurs' strange, wailing songs have the same kinds of universal, categorical rhythms found across human musical cultures. Outside of humans, having rhythm is a rare trait in mammals -- although it can be found elsewhere in the animal kingdom, perhaps most notably in songbirds.

Tesla rolled out version 10.3 of its Full Self-Driving (FSD) Monday morning after CEO Elon Musk pulled the software over the weekend after discovering issues. The electric carmaker initially rolled out the system Saturday evening that improves the ability to detect turn signals, creeping speed and other features. However, Musk tweeted on Sunday morning that issues within the update were discovered and vehicles would be put back to version 10.2 temporarily. 'Please note, this is to be expected with beta software. It is impossible to test all hardware configs in all conditions with internal QA, hence public beta,' the CEO tweeted.

Billionaire entrepreneur Elon Musk has won approval to build a 29-mile tunnel system underneath the Las Vegas strip. It will allow up to 57,000 passengers to hitch rides in Teslas to and from casinos every hour, as well as to the city's airport and the Raiders football stadium. The SpaceX founder's Boring Company already operates a smaller version of the'Vegas Loop' system underneath the Las Vegas Convention Center, which opened earlier this year to lackluster reviews. Instead of futuristic cars zipping people from place to place at high speeds, it features regular Tesla vehicles being driven by humans trundling through a tunnel at just 35mph. However, a huge city-wide expansion of the tunnels, which was proposed by The Boring Company in December last year, has now been approved by Vegas officials.

As space tourism moves from science fiction to science fact, NASA is looking further into the future to when civilians will go far beyond Earth's orbit to visit distant worlds. The American space agency shared its'Visions of the Future' for such journeys in a new video that shows tourists kayaking on the waters of Saturn's moon Titan and free falling through the atmosphere of a distant exoplanet, 42 light-years from Earth. The video was inspired by a travel poster series created by NASA's Jet Propulsion Laboratory, which show several planets and moons that could one day be vacation destinations for humans living on Earth. 'While our robotic explorers have toured our solar system, the only place beyond Earth where humans have stood is the Moon,' NASA shared with the video. 'That's also the next place we'll send astronauts.

This allows for features like Live Translate that allows users to message people with different languages and have it automatically translate your words. It currently works with English, French, German, Italian and a beta version in Japanese, and detects whether a message in WhatsApp, Snap or chat app is different from your system language, and automatically translates it. This detection and processing happens entirely on-device, with no data leaving to be processes elsewhere, and ensuring it works even without data access.
