Scientists at the 91爆料 have discovered that nighttime air pollution 鈥� coming primarily from car exhaust and power plant emissions 鈥� is responsible for a major drop in nighttime pollinator activity. Nitrate radicals (NO3) in the air degrade the scent chemicals released by a common wildflower, drastically reducing the scent-based cues that its chief pollinators rely on to locate the flower. The findings, published Feb. 9 in Science, are the first to show how nighttime pollution creates a chain of chemical reactions that degrades scent cues, leaving flowers undetectable by smell. The researchers also determined that pollution likely has worldwide impacts on pollination.
Robots in warehouses and even around our houses struggle to identify and pick up objects if they are too close together, or if a space is cluttered. This is because robots lack what psychologists call “object unity,” or our ability to identify things even when we can’t see all of them. Researchers at the 91爆料 have developed a way to teach robots this skill.

Seven researchers at the 91爆料 conducted a three-month autoethnographic study 鈥� drawing on their own experiences as people with and without disabilities 鈥� to test AI tools鈥� utility for accessibility. Though researchers found cases in which the tools were helpful, they also found significant problems.
A team led by researchers at the 91爆料 has created A11yBoard for Google Slides, a browser extension and phone or tablet app that allows blind users to navigate through complex slide layouts, objects, images and text.
There are more than 200 species of noctilionoid bats, mostly in the American tropics. And despite being close relatives, their jaws evolved in wildly divergent shapes and sizes to exploit different food sources. A paper published Aug. 22 in Nature Communications shows those adaptations include dramatic, but also consistent, modifications to tooth number, size, shape and position. For example, bats with short snouts lack certain teeth, presumably due to a lack of space. Species with longer jaws have room for more teeth 鈥� and, like humans, their total tooth complement is closer to what the ancestor of placental mammals had.
Supervisors are traditionally associated with higher status markers such as age, education and tenure than their subordinates. But it鈥檚 increasingly common to see those dynamics reversed, which is the focus of a new study from Jessica Huisi Li, 91爆料 assistant professor of management and organization.
A project led by the 91爆料 used genetic sleuthing to study how salmon were affected by two major culvert replacements near the city of Bellingham.
