Scientists are challenging the way many people think about ancient hunter gatherers, after finding that women may have been better hunters than men. New findings have shown that while there are clear differences between the sexes when it comes to biology, the idea of men being naturally better suited to hunting is a myth. New research from professor Cara Ocobock points to women being metabolically better placed to hunt. Ocobock is an assistant professor in the Department of Anthropology and director of the Human Energetics Laboratory at the University of Notre Dame. She published a study on the subject alongside anthropologist Sarah Lacy at the University of Delaware. The research also points to female hunters dating back to the Holocene period which were uncovered buried with hunting tools – and they’re challenging widely held assumptions over gender roles with the study. Ocobock said in a statement: "This was what everyone was used to seeing. This was the assumption that we've all just had in our minds and that was carried through in our museums of natural history." “Here we review and present emerging physiological evidence that females may be metabolically better suited for endurance activities such as running, which could have profound implications for understanding subsistence capabilities and patterns in the past,” the pair wrote. That’s due to the fact that the presence of the hormones estrogen and adiponectin give women the upper hand when it comes to endurance – a factor which would have been “critical in early hunting because they would have had to run the animals down into exhaustion before actually going in for the kill”. The presence of those hormones is better for modulating fat and glucose. As such, estrogen makes the body use stored fats for energy before turning to carbohydrates. “Since fat contains more calories than carbs do, it’s a longer, slower burn, which means that the same sustained energy can keep you going longer and can delay fatigue,” Ocobock said. “Estrogen is really the unsung hero of life, in my mind. It is so important for cardiovascular and metabolic health, brain development and injury recovery.” “With the typically wider hip structure of the female, they are able to rotate their hips, lengthening their steps. The longer steps you can take, the ‘cheaper’ they are metabolically, and the farther you can get, faster.” “When you look at human physiology this way, you can think of women as the marathon runners versus men as the powerlifters.” Sign up for our free Indy100 weekly newsletter How to join the indy100's free WhatsApp channel Have your say in our news democracy.

Peloton has apologised to its customers after technical issues kept them from joining its special Thanksgiving ride. The rides had been held to break the Guinness World Records for the largest live streamed cycling and running classes. But they also had the effect of breaking Peloton’s systems, with riders unable to join the “Turkey Burn” class with instructor Robin Arzón for the first 20 minutes. Peloton’s relatively new chief executive, Barry McCarthy, apologised for the experience on the company’s official Facebook page. “We set out to create an amazing annual Turkey Burn Ride experience, and we let you down,” he wrote on the page. The number of riders “overwhelmed our technical infrastructure”, he said. “I know for many of you, this has become an annual tradition, and we owe you the best possible Member experience,” he wrote. “On behalf of the team, we apologise.” Despite the issues, Peloton was able to set the records for the largest live streamed cycling and running class. The company brought in Guinness World Records officials to verify the count, and were given the record for the ”Most viewers of a static cycling lesson live stream on a Bespoke platform”, as well as for running. The cycling class had 27,550 live participants, a spokesperson said. That was lower than the number that had been seen on the leaderboard, though it is not clear whether the discrepancy was the result of the technical problems. Despite the official recognition, the ride and run is not actually Peloton’s biggest live ride: 2021 and 2020 saw more, with the latter seemingly setting the record at more than 50,000 people, according to Peloton news website Pelobuddy. Peloton saw rapid growth through 2020 and 2021, spurred in large part by the move to work out at home during lockdowns. But it has experienced a number of issues since, including recalls of its bikes and seemingly lower interest as people head back to gyms. It has lost around 80 per cent of its share price value since it was listed towards the end of 2019. And its stock has fallen almost 97 per cent since its record highs in late 2020.

A new lawsuit filed against Nvidia alleged that a file accidentally left on display by one of its employees during a video conference contains data stolen from the car tech company Valeo. The lawsuit alleged that employee Mohammad Moniruzzaman downloaded the “entirety of Valeo’s advanced parking and driving assistance systems source code” in early 2021 without authorization. It says he also downloaded “scores of Valeo Word documents, PowerPoint presentations, PDF files, and Excel spreadsheets explaining various aspects of the technology” before leaving to join Nvidia in August of that year. Valeo is accusing Nvidia of having benefited from the stolen trade secrets. “Mr Moniruzzaman ended his employment at Valeo and took the stolen source code and technical documentation with him to Nvidia, receiving a promotion to a senior position working on the software development for the very same project,” the lawsuit alleged. The alleged data theft reportedly came to light the following year when staff from both Nvidia and Valeo were working over a Microsoft Teams video conference call on a joint parking assistance project. Nvidia was developing the software, while Valeo was providing ultrasonic sensor hardware in the collaborative project for an unnamed automotive parts manufacturer. “On March 8, 2022, one of these videoconference meetings was scheduled. Mr Moniruzzaman, now employed by Nvidia, attended the video conference call… and shared his computer screen during the call,” the lawsuit noted. “When he minimized the PowerPoint presentation he had been sharing, however, he revealed one of Valeo’s verbatim source code files open on his computer,” it said. Valeo participants on the conference call recognised the source code and took a screenshot of it, the company said. “So brazen was Mr Moniruzzaman’s theft, the file path on his screen still read ‘ValeoDocs,’” the lawsuit noted. Mr Moniruzzaman had admitted to stealing Valeo’s software and using it while employed at Nvidia when he was questioned by German police, according to Valeo’s lawsuit. Nvidia has responded that it has no interest in using the stolen code, according to The Verge. But Valeo alleged that its competitor has benefited from the data, which it says would save “millions of dollars in development costs”. Citing these reasons, Valeo is seeking recovery of damages and an injunction to stop Nvidia and its staff from using its trade secrets. The Independent has reached out to Mr Moniruzzaman through Nvidia for a comment.

Artificial intelligence is helping engineers build solar panels out of a “miracle material”. Scientists have long been excited about the possibility of new perovskite tandem solar cells, which could help bring the vastly improved efficiency of perovskite to mass production. They have an efficiency of more than 33 per cent, dramatically higher than conventional silicon solar cells. Those tandem solar cells come with a host of other benefits, too. They rely on inexpensive raw materials and can be made relatively easily. Engineers have faced a problem, however, in making them cheaply and at scale. To make them efficient, manufacturers need to make a very thin, high-grade layer of perovskite. Doing that is difficult. It relies on a complex process that varies significantly, seemingly with little explanation. Trying to improve that process has often relied on a gradual process of trying out new possibilities through trial and error. Now scientists have successfully built a new system that uses artificial intelligence to try and work out how to build those layers better. Instead of picking through video recordings to work out how different layers work, researchers were able to train a computer system to spot the hidden signs of good and bad coatings. After the system was built, it was able to be used better understand how to change the production to make it more efficient, researchers said. “These are extremely exciting results,” said Ulrich W Paetzold, a researcher from the Karlsruhe Institute of Technology, who worked on the new study. “Thanks to the combined use of AI, we have a solid clue and know which parameters need to be changed in the first place to improve production. “Now we are able to conduct our experiments in a more targeted way and are no longer forced to look blindfolded for the needle in a haystack. This is a blueprint for follow-up research that also applies to many other aspects of energy research and materials science.” An article describing the breakthrough, ‘Discovering Process Dynamics for Scalable Perovskite Solar Cell Manufacturing with Explainable AI’, is published in Advanced Materials.
