A handful of 60,000-year-old arrow tips unearthed in a South African rock shelter are the oldest evidence of poison weapons in the world, a new study finds.The discovery pushes back the confirmed use of poison weapons by hunter-gatherers by over 50,000 years.In the new study, scientists chemically analyzed 10 arrow tips that had been found decades ago at Umhlatuzana rock shelter. They found that five still contained traces of slow-acting poisons. These substances, likely derived from a species of tumbleweed, would have weakened targeted prey and substantially cut down the time and energy required for persistence hunts, the authors wrote…

Every fall, dozens of maple and oak trees in my neighborhood shed their leaves. Thus begins the constant drone of gas-powered leaf blowers every day through early December. The noise is by far the most annoying thing about these yard tools, but I can appreciate it’s a necessary evil — unless you prefer to pick up a blister-inducing rake.Whisper Aero argues there’s a better way. The company is using aerospace tech to quiet the noisy devices, introducing the T1 leaf blower at CES 2026 under its sub-brand Tone Outdoors. The company promises the T1 is 80 percent quieter and 60…

It is never too late for you to develop a new skill and master it so well that you can’t help but stunt on at least 20,000 other people. Case in point: There is a 95-year-old grandmother out there who has never played an FPS game and might be a better shot than me, a 28-year-old who has played these games most of his life. As reported by Automaton, ZachsMaxed, a professional FPS player, recently shared a video on Twitter showing how his grandmother, Anne Krohley, is simply a better shot than many other players. In the clip, Krohley can…

Researchers from the Leonardo da Vinci DNA Project (LDVP) that by analyzing the drawing of Holy Child and other Renaissance artifacts, such as letters written by a da Vinci relative, they have recovered some Y chromosome DNA sequences that appear to belong to a genetic group of people with common ancestors in Tuscany, where the genius and Renaissance master was born in 1452. The findings, first reported in Science, could be the first time scientists have identified DNA from da Vinci himself.The DNAHistorical artifacts can accumulate DNA from the environment and potentially offer useful information about the people who created…

NASA’s Johnson Space Center was front and center Jan. 4, 2026, as the Houston Texans faced the Indianapolis Colts during Space City Day at NRG Stadium. Fans watched the Texans win while getting a close look at NASA’s Artemis II mission, the first crewed flight of the Artemis campaign.  The Artemis II mission will send four astronauts—NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, along with CSA (Canadian Space Agency) astronaut Jeremy Hansen—around the Moon and back to Earth to test Orion spacecraft systems in deep space and help lay the groundwork for future lunar missions.  NASA connected fans with the agency’s next giant leap, reinforcing Space City’s role in shaping the future…

If you’re off-roading, it’s a neat idea to use your engine to top up your battery, which prompted Bluetti to launch the Charger. You could hook it to your alternator and draw off energy as you drove to make sure you turned up to your campsite with full batteries. But if you’re also toting around solar panels on your roof, then it’s a shame you can’t also use that power to top up. This omission is what prompted Bluetti to turn up to CES 2026 with the Charger 2, which will take power from your engine and your solar panels…

Liminal spaces and the “backrooms” have become overused concepts on the internet, with people labeling any room or area that is even slightly off as some creepy space. It’s annoying and tiring. But I still like the idea of eerie, dead areas hidden in our world in places like forgotten hallways and empty hotel rooms. I also like fast-paced boomer shooters that feel great. So I’m a big fan of the newly released indie FPS Oddcore, which mashes all of this stuff up into one stylish game. Out now on Steam via early access, Oddcore doesn’t have much setup. One…

It does an excellent job of tuning out…

The U.S. government has officially resurrected the food pyramid — and flipped it on its head.The new food chart emphasizes meats, dairy and what it calls “healthy fats,” as well as fruits and vegetables. It accompanies new nutrition guidance that upholds some well-established diet recommendations while breaking with others.The Departments of Agriculture and Health and Human Services released the new dietary guidelines on Wednesday (Jan. 7), and in doing so, they retired MyPlate, a visual guide to healthy eating that replaced the food pyramid in 2011. The so-called New Pyramid is an inverted triangle with protein, dairy and “healthy fats”…
