80 mph speed record for glacier fracture helps reveal the physics of ice sheet collapse
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.

Foul fumes pose pollinator problems
Scientists at the University of Washington have discovered that nighttime air pollution — coming primarily from car exhaust and power plant emissions — 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.

Q&A: Helping robots identify objects in cluttered spaces
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 University of Washington have developed a way to teach robots this skill.
UW-developed smart earrings can monitor a person’s temperature
University of Washington researchers introduced the Thermal Earring, a wireless wearable that continuously monitors a user’s earlobe temperature. Potential applications include tracking signs of ovulation, stress, eating and exercise. The smart earring prototype is about the size and weight of a small paperclip and has a 28-day battery life.

Shallow soda lakes show promise as cradles of life on Earth
Field observations from an unusual lake show that in environments known as “soda lakes” phosphate can concentrate at the very high levels needed for the basic molecules of life to emerge. A shallow, salty lake in western Canada gives new support to Charles Darwin’s idea that life could have emerged in a “warm little pond.”

Scientists reveal superconductor with on/off switches
Researchers led by Jiun-Haw Chu, a University of Washington associate professor of physics, and Philip Ryan, a physicist at the U.S. Department of Energy’s 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.

North Atlantic’s marine productivity may not be declining, according to new study of older ice cores
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.

Fruit, nectar, bugs and blood: How bat teeth and jaws evolved for a diverse dinnertime
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 — and, like humans, their total tooth complement is closer to what the ancestor of placental mammals had.

Q&A: UW expert on rise of younger, less experienced bosses in the workplace
Supervisors are traditionally associated with higher status markers such as age, education and tenure than their subordinates. But it’s increasingly common to see those dynamics reversed, which is the focus of a new study from Jessica Huisi Li, University of Washington assistant professor of management and organization.

DNA shows where Washington culvert replacements helped spawning salmon
A project led by the UW 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 UW and NOAA are studying the use of eDNA in future environmental impact reporting.

UW announces four non-compliant items in recent USDA inspection of animal facilities in Seattle
The University of Washington’s animal facilities on the Seattle campus underwent a routine, unannounced inspection by the United States Department of Agriculture (USDA) between Sept. 12 and 14. The inspection identified four non-compliant items, all of which had previously been self-reported by the UW and rectified before the inspection took place.
Closing in on the elusive neutrino
In a paper published Sept. 6 in Physical Review Letters, an international team of researchers in the United States, Germany and France reported that a distinctive strategy they have used shows real promise to be the first approach to measure the mass of the neutrino. Once fully scaled up, their collaboration — Project 8 — could also reveal how neutrinos influenced the early evolution of the universe as we know it.
