Monkeys in Gibraltar self-medicate with soil to help them digest tourists' junk food

Scientists have discovered unexpected water-ice clouds on a distant, Jupiter-like exoplanet, challenging current atmospheric models. By directly imaging Epsilon Indi Ab with the James Webb Space Telescope, they found less ammonia than expected—likely hidden by thick, patchy clouds. The finding reveals new layers of complexity in giant planets and shows how much we still have to learn.

A vivid green pitviper hiding in Sichuan’s misty mountains has been revealed as a completely new species. Scientists had overlooked it for decades, assuming it was a common snake—until DNA analysis proved otherwise. Named after Laozi, it features striking differences between males and females, including bold stripes and eye colors. The discovery highlights just how many unknown species may still be lurking in well-studied regions.

Fluorescent probes have transformed modern biology by allowing researchers to tag and visualize individual molecules in living cells, tissues, and animals. Using these tools, researchers can watch viruses infect cells in real time, observe cellular trash collection, and track the signaling that spurs tumor growth. Now, scientists at Albert Einstein College of Medicine and the Salk Institute for Biological Studies have developed a new molecular imaging technology that illuminates proteins inside

At more than one million degrees, the sun's atmosphere—the corona—is incredibly hot; but not everywhere. Time and again, huge structures of significantly cooler solar plasma—about 10,000 degrees—appear within the corona. These structures are known as prominences. They span up to several thousand kilometers and often resemble flickering flames that can take on a wide variety of shapes. Despite their delicate appearance, they are massive "chunks of matter": their density exceeds that of the surrou
