A new analysis of rocks thought to be at least 2.5 billion years old helps clarify the chemical history of Earth's mantle -- the geologic layer beneath the planet's crust. The findings hone scientists' understanding of Earth's earliest geologic processes, and they provide new evidence in a decades-long scientific debate about the geologic history of Earth. Specifically, the results provide evidence that the oxidation state of the vast majority of Earth's mantle has remained stable through geologic time and has not undergone major transitions, contrary to what has been suggested previously by other researchers.

Researchers analyzed the financial and environmental costs and benefits of four biofuels crops used to produce sustainable aviation fuels in the U.S. They found that each feedstock -- corn stover, energy sorghum, miscanthus or switchgrass -- performed best in a specific region of the rainfed United States. Their study will help growers and policymakers select the feedstocks most suited to meeting goals like reducing production costs, lowering greenhouse gas emissions and building soil carbon stocks.

Large language models may pass medical exams with flying colors but using them for diagnoses would currently be grossly negligent. Medical chatbots make hasty diagnoses, do not adhere to guidelines, and would put patients' lives at risk. A team has systematically investigated whether this form of artificial intelligence (AI) would be suitable for everyday clinical practice. Despite the current shortcomings, the researchers see potential in the technology. They have published a method that can be used to test the reliability of future medical chatbots.

An international team of researchers has discovered that metallic minerals on the deep-ocean floor produce oxygen -- 13,000 feet below the surface. Discovery challenges long-held assumptions that only photosynthetic organisms generate Earth's oxygen. Minerals at the abyssal seafloor appear to act like geobatteries to produce oxygen in a process that does not require sunlight.

Engineers have shown that using a type of AI that revolutionized computer vision can greatly enhance modern adaptive radar systems. And in a move that parallels the impetus of the computer vision boom, they have released a large dataset of digital landscapes for others to build on their work.

A new study describes a chemical reaction that can convert Styrofoam into a high-value conducting polymer known as PEDOT:PSS. Researchers also noted that the upgraded plastic waste can be successfully incorporated into functional electronic devices, including silicon-based hybrid solar cells and organic electrochemical transistors.
