From June 29 onward, Switzerland's glaciers will have exhausted their snow reserves. Every liter of meltwater now causes them to lose mass—this is Glacier Loss Day. Between the extreme years of 2003 and 2022 alone, 200 square kilometers of ice—an area almost as large as the
When biologists study cooperation in animals, they usually offer just a single task at a time. But what happens when animals can choose among several opportunities to work together? Biologists at Utrecht University discovered that this can make a remarkable difference.
The first empirical evidence of how A-level grading in the pandemic affected university applications corroborates concerns about disproportionate benefits for private schools. Disadvantaged students also benefited, however, and the long-term effects for these groups could
A global team has cracked a decades-old mystery, revealing the atomic structures of the molecules in our eyes that allow us to see colors. "To understand how we detect light and perceive colors, we need to know the exact structure of light-sensitive molecules in our eyes," said
