Why a New England city is building tunnels to protect an imperiled salamander

Keene, New Hampshire is constructing tunnels to help wood salamanders safely cross a street during their spring migration. The city deployed crews with flashlights to monitor the amphibians' movements on a rainy March night.

Smithsonian ornithologist John Rappole reconsidered why birds migrate

Ornithologist John Rappole challenged the view that migratory songbirds were temporary tropical visitors by examining their year-round ecology. He demonstrated that these birds spent significant time in tropical forests during winter months, warranting greater scientific attention to their non-breeding habitats.

Mapping Io’s Hidden Heat With NASA’s Juno

NASA's Juno spacecraft used its Microwave Radiometer instrument to map heat on Jupiter's moon Io during two close flybys in December 2023 and January 2024. The black lines show the instrument's footprints from the December 30 flyby that primarily covered the northern hemisphere, while blue lines represent the subsequent January flyby coverage.

NASA’s Juno Peers Beneath Io’s Surface

The Microwave Radiometer aboard NASA's Juno spacecraft detected heat rising from beneath Io's surface using low-frequency microwave channels at 0.6 and 1.25 gigahertz. These channels can penetrate approximately 6 to several kilometers below the moon's surface, unlike infrared instruments that only measure surface temperature.

Lab-grown mini brains may predict which Alzheimer’s treatments will work

Miniature brain models grown from patients' cells showed different responses to an antidepressant in Alzheimer's-related tissue. The organoids could guide personalized treatments and provide diagnostic clues through particles they release.

A strange quantum effect dramatically boosts energy transfer

A proton-assisted mechanism improves energy transfer between quantum dots and nearby molecules by briefly shifting position to coordinate electron movement. The proton returns to its original location after facilitating the triplet energy transfer through this quantum shuttle effect.
