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.

UW assessment finds fentanyl and methamphetamine smoke linger on public transit vehicles
Two years ago, as life regained its rhythm and public transit once again filled with people, train and bus operators spotted a troubling trend. Some operators reported instances of people smoking drugs on their vehicles, and worried that the haze it created could linger, potentially affecting workers’ physical and mental health. Spurred by operators’ concerns,…

REBURN: A new tool to model wildfires in the Pacific Northwest and beyond
Researchers with the University of Washington and the U.S. Forest Service have developed a new tool, REBURN, that can simulate large forest landscapes and wildfire dynamics over decades or centuries under different wildfire management strategies. The model can simulate the consequences of extinguishing all wildfires regardless of size, which was done for much of the 20th century and has contributed to a rise in large and severe wildfires, or of allowing certain fires to return to uninhabited areas to help create a more “patchwork” forest structure that can help lessen fire severity. REBURN can also simulate conditions where more benign forest landscape dynamics have fully recovered in an area.

Muon g-2 doubles down with latest measurement, explores uncharted territory in search of new physics
A particle physics experiment decades in the making — the Muon g-2 experiment — looks increasingly like it might set up a showdown over whether there are fundamental particles or forces in the universe that are unaccounted for in the current Standard Model. On Aug. 10, the international team of scientists behind Muon g-2 — pronounced “g minus 2” — released the world’s most precise measurement yet of the anomalous magnetic moment of the muon. Calculating the muon’s magnetic moment at a high precision will indicate whether it is interacting solely with the particles and forces known today, or if unknown particles or forces are out there.

New algorithm ensnares its first ‘potentially hazardous’ asteroid
An asteroid discovery algorithm — designed to uncover near-Earth asteroids for the Vera C. Rubin Observatory’s upcoming 10-year survey of the night sky — has identified its first “potentially hazardous” asteroid, a term for space rocks in Earth’s vicinity that scientists like to keep an eye on. The roughly 600-foot-long asteroid, designated 2022 SF289, was discovered during a test drive of the algorithm with the ATLAS survey in Hawaii. Finding 2022 SF289, which poses no risk to Earth for the foreseeable future, confirms that the next-generation algorithm, known as HelioLinc3D, can identify near-Earth asteroids with fewer and more dispersed observations than required by today’s methods. That is important because, though scientists know of more than 2,000 near-Earth asteroids, they estimate that another 3,000 await discovery!

With a new app, smart devices can have GPS underwater
A team at the University of Washington has developed the first underwater 3D-positioning app for smart devices. When at least three divers are within about 98 feet of each other, the app tracks each user’s location relative to the leader.

Researchers put a new twist on graphite
A team led by researchers at the University of Washington reports that it is possible to imbue graphite — the bulk, 3D material found in No. 2 pencils – with physical properties similar to graphite’s 2D counterpart, graphene. Not only was this breakthrough unexpected, the team also believes its approach could be used to test whether similar types of bulk materials can also take on 2D-like properties. If so, 2D sheets won’t be the only source for scientists to fuel technological revolutions. Bulk, 3D materials could be just as useful.

Researchers make a quantum computing leap with a magnetic twist
A team led by scientists and engineers at the University of Washington has announced a significant advancement in developing fault-tolerant qubits for quantum computing. In a pair of papers published June 14 in Nature and June 22 in Science, they report that, in experiments with flakes of semiconductor materials — each only a single layer of atoms thick — they detected signatures of “fractional quantum anomalous Hall” (FQAH) states. The team’s discoveries mark a first and promising step in constructing a type of fault-tolerant qubit because FQAH states can host anyons — strange “quasiparticles” that have only a fraction of an electron’s charge. Some types of anyons can be used to make what are called “topologically protected” qubits, which are stable against any small, local disturbances.

Phosphate, a key building block of life, found on Saturn’s moon Enceladus
An international team including a UW scientist found that the water on one of Saturn’s moons harbors phosphates, a key building block of life. The team used data from NASA’s Cassini space mission to detect evidence of phosphates in particles ejected from the ice-covered global ocean of Saturn’s moon Enceladus.
