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.

An AI-powered analysis of 25 years of satellite images yields the surprising finding that methane emissions in Turkmenistan, a former Soviet republic and major oil-producing region, actually increased in the years following the dissolution of the Soviet Union.

Natural history museums have entered a new stage of discovery and accessibility 鈥 one where scientists around the globe and curious folks at home can access valuable museum specimens to study, learn or just be amazed. This new era follows the completion of openVertebrate, or oVert, a five-year collaborative project among 18 institutions to create 3D reconstructions of vertebrate specimens and make them freely available online. The team behind this endeavor, which includes scientists at the 91探花 and its Burke Museum of Natural History & Culture, published a summary of the project March 6 in the journal BioScience, offering a glimpse of how the data can be used to ask new questions and spur the development of innovative technology.

New research documents the fastest-known large-scale breakage along an Antarctic ice shelf. In 2012, a 6.5-mile crack formed in about 5 and a half minutes, showing that ice shelves can effectively shatter, though the speed of breakage is reduced by seawater rushing in. These results can help improve ice-sheet models and projections for future sea level rise.

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.

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探花 have developed a way to teach robots this skill.

Holly Barker, a 91探花 teaching professor of anthropology, and three current members of the 91探花football team 鈥 Ulumoo Ale, Makell Esteen and Faatui Tuitele 鈥 are studying how the skills they develop to maximize their chances of victory on the field have applications outside the stadium. Their work, which is ongoing, is showing that the research methods and analytical abilities of student-athletes are applicable in academic and research settings, as well as jobs in a variety of fields.

Two 91探花professors teamed up to study how climate change will affect predator-prey interactions in snowy landscapes. Together with a group of researchers, the two measured snow properties that led to a “danger zone,” where prey would sink but predators would not.

Researchers led by Jiun-Haw Chu, a 91探花 associate professor of physics, and Philip Ryan, a physicist at the U.S. Department of Energy鈥檚 Argonne National Laboratory, have found a superconducting material that is uniquely sensitive to outside stimuli, enabling the superconducting properties to be enhanced or suppressed at will. This discovery could enable new opportunities for switchable, energy-efficient superconducting circuits.

With several university athletic programs around the country 鈥 including the 91探花 鈥斅燼nnouncing moves to new conferences that will likely increase travel for student-athletes, a group of sleep and circadian scientists and physicians have published a white paper describing the significance of repeated, chronic jet lag on student-athlete health and performance 鈥 both in academics and in sports, and suggesting strategies to reduce the consequences of travel across time zones.

New research from Andrew Hafenbrack, associate professor of management and organization in the 91探花 School of Business, and other institutions examines the impact of leadership style on prospective Black employees who apply for jobs in less-diverse companies.

Currently, more than half of all cervical cancers diagnosed in the United States are in people who are overdue for screening or have never been screened. In a new study, researchers report that mailing HPV test kits significantly increased cervical cancer screening rates.

To paraphrase Mark Twain, reports of declining phytoplankton in the North Atlantic may have been greatly exaggerated. Analysis of a Greenland ice core going back 800 years shows that atmospheric chemistry, not dwindling phytoplankton populations, explains the recent ice core trends.

A team led by researchers at the 91探花 has developed deep-learning algorithms that let users pick which sounds filter through their headphones in real time. Either through voice commands or a smartphone app, headphone wearers can select which sounds they want to include from 20 classes, such as sirens, baby cries, speech, vacuum cleaners and bird chirps.

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探花 assistant professor of management and organization.
