Glowing urine and shining bark: Scientists discover the secret visual language of deer

Glowing urine and shining bark: Scientists discover the secret visual language of deer

During mating season, when male white-tailed deer want to get noticed by the opposite sex and warn off rivals, they rub their antlers against trees and scrape the forest floor. Then they pee on these patches. But there is more to these physical and scent markers than meets the eye—or nose. According to a new study published in the journal Ecology and Evolution, they also glow so that other deer can see them when it's dark.

Africa's rarest carnivore: The story of the first Ethiopian wolf ever captured, nursed and returned to the wild

Africa's rarest carnivore: The story of the first Ethiopian wolf ever captured, nursed and returned to the wild

What's the value of one animal? When a wild animal is found badly injured, the most humane option is often euthanasia to prevent further suffering. That's what usually happens, and often for good reason. Even when the resources to rescue one animal are available, a rehabilitated animal brought back into the wild might be rejected by its group, or struggle to find food or escape predators. If it does survive, it may fail to reproduce, and leave no lasting mark on the population.

Observations catch galaxy cluster in the process of merging

Observations catch galaxy cluster in the process of merging

Astronomers have used the Keck Observatory's DEIMOS multi-object spectrograph to observe a nearby galaxy cluster designated RXC J0032.1+1808. As a result, they found that the cluster undergoes a major merging event. The finding was presented in a research paper published December 16 on the pre-print server arXiv.

New image sensor breaks optical limits

New image sensor breaks optical limits

Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to unlocking microscopic details inside living cells. Yet despite decades of innovation, a fundamental barrier has persisted: capturing high-resolution, wide-field images at optical wavelengths without cumbersome lenses or strict alignment constraints.

An AI-based blueprint for designing catalysts across materials

An AI-based blueprint for designing catalysts across materials

Hydrogen peroxide is widely used in everyday life, from disinfectants and medical sterilization to environmental cleanup and manufacturing. Despite its importance, most hydrogen peroxide is still produced using large-scale industrial processes that require significant energy. Researchers are thus seeking cleaner alternatives.

Mechanism for twisted growth of plant organs discovered

Mechanism for twisted growth of plant organs discovered

From morning glories spiraling up fence posts to grape vines corkscrewing through arbors, twisted growth is a problem-solving tool found throughout the plant kingdom. Roots "do the twist" all the time, skewing hard right or left to avoid rocks and other debris.
