NASA is leveraging its expertise and enhancing its test facilities to help address a rare but persistent aviation hazard: icing that occurs when aircraft encounter unusually large, very cold water droplets in clouds. The problem, known as “supercooled large droplet icing,” occurs when aircraft fly through clouds containing unusually large drops of water that are very cold but remain liquid. When a plane passes through those drops, they can rapidly freeze to surfaces that are not protected from ice buildup.

Diligent sleuthing by astronomers has broken open a cold case in the data archive of NASA’s Hubble Space Telescope . In a study published Monday in Nature Astronomy, researchers report uncovering a surprising chemical clue that indicates the white dwarf star HS 0209+0832 may host a second-generation planet. A white dwarf is the remnant core of a low-mass star that has burned through all its nuclear fuel and lost its outer envelope of gas and dust to space. A second-generation planet is a world that forms around the stellar remnant from its cast-off material.

Scientists found that prolonged fasting triggers major changes throughout the body, but many of the most interesting effects only appeared after about three days without food. The results suggest fasting may influence health in ways that go beyond weight loss and could eventually inspire treatments that mimic its effects.
