When asked by WIRED about the origin of the bite-mark claim, Hatton replied, “The bite marks are very clear, and are not all straight punctures but lateral bites where you can clearly see the shape of the tooth. You can also tell from the edges of the hole whether the break is clean, or if ..

Credit: Wanqing Zhang Credit: Wanqing Zhang Scientists at Pennsylvania State University have developed a novel conductive ink that can be painted directly onto the skin in colorful custom designs, turning into a functional electrode for biomonitoring after drying. They described their work in a new paper published in the Proceedings of the National Academy of ..
Until about 60,000 years ago, diminutive hominin cousins, Homo floresiensis (affectionately nicknamed Hobbits for obvious reasons), shared the island of Flores with Komodo dragons, pygmy elephants, and giant rats. Based on the presence of hominin and pygmy elephant bones in the same layers of cave sediment, it originally looked like the Hobbits had hunted and ..
But flat-packed, stackable satellites allow operators to deliver more capability to orbit faster. Starship will take this to the next level with its capacity to launch SpaceX’s more powerful Starlink V3s. “On a Falcon 9, they can only launch 27 of these V2s,” Jones said. “The Starship can launch 60 of these larger V3s. What ..
“We basically work from the assumption that if we want data, then we need to obtain it ourselves,” Sapiezynski said of their account cloning approach. “Even if we did, for example, want to use the official TikTok researcher API, none of the user agency is covered there. You can see what content is available, but ..
The proliferation of nuclear power in space got a little more real Tuesday with the launch of a small satellite developed by a Florida-based company specializing in nuclear micro-power technology. It’s a long way from launching a bona fide nuclear reactor, a breakthrough that could help power a permanent Moon base and efficiently drive rockets ..
To replace ALARA, the NRC will start with a limit at which evidence clearly indicates radiation impacts would be apparent and set exposure thresholds below that. From lowest to highest exposure, these thresholds will require increasingly aggressive efforts to limit exposures. The language of the details is a bit confused, however. As its name implies, ..
NASA has a clear interest in saving the Swift mission. The $500 million observatory’s primary mission is detecting gamma-ray bursts, the most powerful explosions in the known Universe. Despite its age, astrophysicists still rely on Swift’s multi-wavelength instruments to identify and locate gamma-ray bursts for follow-up observations by other observatories. But part of the reason for ..
The new statistics released by PEER were made public as a result of a lawsuit PEER and other groups filed to compel the Chemical Safety Board to disclose industrial chemical releases as required by the Clean Air Act. A federal judge ruled in 2019 that communities have a right to know what hazardous chemicals are ..
The simulations that captured the localized effects of individual large impacts also produced wholesale recycling of crust back into the mantle, with material dripping down to depths of at least 600 kilometers. Johnson thinks this recycling explains why so little Hadean crust survived to the present. It also explains, he argues, the near-total absence of ..
