Soybean oil, the most widely consumed cooking oil in the United States and a staple of processed foods, contributes to obesity, at least in mice, through a mechanism scientists are now beginning to understand.

Electric discharges have for the first time been recorded within the storms and whirlwinds of dust – known as dust devils – that sweep across the surface of Mars. Captured by the microphone of the SuperCam instrument on board NASA's Perseverance rover, the signals were analysed by a team of scientists from the CNRS, Université de Toulouse and the Observatoire de Paris – PSL, working as part of an international team. The discharges represent a major discovery with immediate implications for our understanding of the atmospheric chemistry, climate and habitability of Mars, as well as for future robotic and manned missions there. These findings are published in the journal Nature on November 26, 2025.

The method uses common household items and reduces toxic substances to identify both the type and quantity of illicit drugs.
