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!

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.

Out of the frying pan: Coyotes, bobcats move into human-inhabited areas to avoid apex predators — only to be killed by people
New research shows that in Washington state, the presence of two apex predators — wolves and cougars — does indeed help keep populations of two smaller predators in check. But by and large the apex predators were not killing and eating the smaller predators, known as mesopredators. Instead, they drove the two mesopredator species — bobcats and coyotes — into areas with higher levels of human activity. And people were finishing the job.

Africa’s grassy habitats emerged 10+ million years earlier than previously thought
A pair of studies published April 14 in the journal Science paint a new picture about apes, ancient Africa and the origins of humans. Many scientists had once hypothesized that the first apes to evolve in Africa more than 20 million years ago ate primarily fruit and lived within the thick, closed canopy of a nearly continent-wide forest ecosystem. Instead, the new research indicates that early apes ate a leafy diet in a more arid ecosystem of varyingly open woodlands with abundant grasses.

Northern and southern resident orcas hunt differently, which may help explain the decline of southern orcas
In the Pacific Northwest and British Columbia, southern resident orcas have experienced no net population growth since the 1970s, with just 73 left at the most recent count. But northern resident orcas, which have a similar diet, territory and social structure, have grown steadily, now numbering more than 300. A new study led by scientists at the University of Washington and NOAA Fisheries may help explain why: The two populations differ in how they hunt for salmon, their primary and preferred food source, a key difference that conservationists will have to take into account when designing interventions to help southern residents.
