Small seabirds rely on crosswinds to navigate the open ocean

Daphnia, also known as water fleas, are artists of defense. When their predators live nearby, the water fleas change their body structure to make themselves more difficult to eat. Professor Linda Weiss from Ruhr University in Bochum, Germany and her team have identified a chemoreceptor gene family that encodes the corresponding receptors, and is thus involved in detecting predators' signals.

We hardly give them a second thought, but everyday objects like bags and backpacks belong to a long technological tradition that may stretch back hundreds of thousands of years.

The Southwest Research Institute-led Ultraviolet Spectrograph (UVS) instruments aboard ESA's Jupiter Icy Moons Explorer (Juice) spacecraft and NASA's Europa Clipper made unique observations of interstellar comet 3I/ATLAS in late 2025. SwRI leads the UVS instruments on both spacecraft, simultaneously imaging both hemispheres of the comet and detecting the comet's ultraviolet emissions.
