Could life be found in frozen sea spray emitted from moons orbiting Saturn or Jupiter? New research finds that life can be detected in a single ice grain containing one bacterial cell or portions of a cell. The results suggest that if life similar to that on Earth exists on these planetary bodies, this life should be detectable by instruments launching in the fall.
In 2021, Colin Orion Chandler started Active Asteroids Citizen Science, a partnership between NASA, Zooniverse, astronomers and thousands of citizen scientist volunteers. The initiative is searching for so-called “active asteroids,” which have comet-like tails and could hold clues to the formation of our solar system, among other cosmic mysteries. Chandler, now a 91探花 researcher, and his team recently announced they have discovered 15 active asteroids, and are continuing the search for more of these unusual and rare objects.

In an experiment akin to stop-motion photography, an international team co-led by 91探花 scientists has isolated the energetic movement of an electron in a sample of liquid water 鈥� while 鈥渇reezing鈥� the motion of the much larger atom it orbits.
Scientists at the 91探花 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.

The New York Climate Exchange, a first-of-its-kind organization working to implement innovative climate solutions in New York City and across the globe, on Nov. 9 announced Stephen Hammer as its founding chief executive officer. The 91探花 is a core member of the exchange.
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.
A project led by the 91探花used genetic sleuthing to study how salmon were affected by two major culvert replacements near the city of Bellingham. One project, a major upgrade under Interstate-5, had a big impact, while the other old culvert may have been less of a barrier to fish. Authors from the 91探花and NOAA are studying the use of eDNA in future environmental impact reporting.
