Pill bugs don't just use the minerals they eat—they rebuild them inside their bodies

By analyzing peat cores, researchers have shown how populations of nesting seabirds have fluctuated on a sub-Antarctic island over 8,000 years. They found that bird numbers rose and fell alongside shifts in climate, offering new clues about how future climate change could impact seabird populations.

Researchers at The University of Osaka, in collaboration with ULVAC, Inc. and Ritsumeikan University, have developed a new LED structure that generates circularly polarized light from a single chip. By combining a semipolar InGaN light-emitting structure with a stripe-shaped silicon nitride metasurface, the team created a compact light source that reduces energy-conversion loss and operates at room temperature.

High in the forests of Hawai'i, songbirds are stealing twigs and moss from one another's nests. UC Riverside researchers found this quiet canopy crime is surprisingly common and could threaten species already struggling to survive.

Listen to this audio excerpt from Rebekah Tolatovicz, a mechanical technician lead supporting the Orion spacecraft’s main contractor Lockheed Martin: At NASA’s Kennedy Space Center in Florida, there is a fleet of Orion spacecraft in work, and Rebekah Tolatovicz’s hands have helped build each one. Tolatovicz works to build, integrate, and test the spacecraft used […]
