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.

What’s in a name? Sometimes, the climate
By analyzing records from the U.S. Social Security Administration, two scientists at the University of Washington and Ohio University have discovered that the popularity of certain month and season names for girls varies by geographic region in the continental United States. The name April dominates monthly names in southern states where spring arrives early in the year. June is more popular in northern states where spring blooms later. Autumn is also more prevalent in the northern U.S., a region known for its brilliant fall foliage.

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.

Warm liquid spewing from Oregon seafloor comes from Cascadia fault, could offer clues to earthquake hazards
UW oceanographers discovered warm, chemically distinct liquid shooting up from the seafloor about 50 miles off Newport. They named the unique underwater spring “Pythia’s Oasis.” Observations suggest the spring is sourced from water 2.5 miles beneath the seafloor at the plate boundary, regulating stress on the offshore subduction zone fault.

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.

Human-wildlife conflicts rising worldwide with climate change
Research led by scientists at the University of Washington’s Center for Ecosystem Sentinels reveals that a warming world is increasing human-wildlife conflicts globally. They show that climate shifts can drive conflicts by altering animal habitats, the timing of events, wildlife behaviors and resource availability. It also showed that people are changing their behaviors and locations in response to climate change in ways that increase conflicts.

Newly discovered form of salty ice could exist on surface of extraterrestrial moons
Scientists suspect that the red streaks crossing the surface of Jupiter’s moon Europa is a frozen mixture of water and salts, but its chemical signature matches no known substance on Earth. Now researchers have discovered a new type of solid crystal that forms when water and table salt combine in cold, pressurized conditions. Researchers believe the new substance created in a lab on Earth could form at the surface and bottom of these worlds’ deep oceans.

Ice cores show even dormant volcanoes leak abundant sulfur into the atmosphere
Non-erupting volcanoes leak a surprisingly high amount of sulfur-containing gases. A Greenland ice core shows that volcanoes quietly release at least three times as much sulfur into the Arctic atmosphere than estimated by current climate models. Aerosols are the most uncertain aspect of current climate models, so better estimates could improve the accuracy of long-term projections.

How did the Butterfly Nebula get its wings? It’s complicated
Something is amiss in the Butterfly Nebula. When a team led by astronomers at the University of Washington compared two exposures of this planetary nebula that had been taken by the Hubble Space Telescope in 2009 and 2020, they saw dramatic changes in the material within its “wings.” As the team will report on Jan. 12 at the 241st meeting of the American Astronomical Society in Seattle, powerful winds are apparently driving complex alterations of material within the Butterfly Nebula, behavior not seen in planetary nebulae to date. The researchers want to understand how such activity is possible from what should be a “sputtering, largely moribund star with no remaining fuel.”

The seven-year photobomb: Distant star’s dimming was likely a ‘dusty’ companion getting in the way, astronomers say
University of Washington astronomers were on the lookout for “stars behaving strangely” when an automated alert from pointed them to Gaia17bpp, a star that had gradually brightened over a 2 1/2-year period. But follow-up analyses indicated that Gaia17bpp wasn’t changing. Instead, the star is likely part of a rare type of binary system. Its apparent brightening was the end of a years-long eclipse by an unusual, “dusty” stellar companion.
Plastic pollution in the oceans is an equity issue, says UW-led report
A recent report and upcoming virtual event looks at the unequal effect of marine plastics on different communities. The international report led by UW’s Yoshitaka Ota covers topics ranging from the COVID-19 pandemic’s impact on plastic pollution to a critique of Coca-Cola’s waste initiative.

Climate ‘presses’ and ‘pulses’ impact Magellanic penguins — a marine predator — with guidance for conservationists
Climate change will reshape ecosystems through two types of events: short-term, extreme events — or “pulses” — and long-term changes, or “presses.” Understanding the effects of presses and pulses is essential as conservationists and policymakers try to preserve ecosystems and safeguard biodiversity. Researchers at the University of Washington have discovered how different presses and pulses impacted Magellanic penguins — a migratory marine predator — over nearly four decades and found that, though individual presses and pulses impacted penguins in a variety of ways, both were equally important for the future survival of the penguin population. They also found that these types of climate changes, taken together, are leading to an overall population decline at their historically largest breeding site.
Warming oceans have decimated marine parasites — but that’s not a good thing
Save the … parasites? Analyzing 140 years of parasite abundance in fish shows dramatic declines, especially in parasites that rely on three or more host species. The decline is linked to warming ocean temperatures. Parasitic species might be in real danger, researchers warn — and that means not just fewer worms, but losses for the entire ecosystem.

Signals from the ionosphere could improve tsunami forecasts
An underwater volcanic eruption in January 2022 created ripple effects throughout the world’s atmosphere and oceans. University of Washington scientists analyzed that event to show how GPS signals could help monitor future volcanoes and tsunamis.
Trouble falling asleep at night? Chase that daytime light, study shows
A study measuring the sleep patterns of students at the University of Washington found that students fell asleep later in the evening and woke up later in the morning during winter, when daylight hours on the UW’s Seattle campus are limited and the skies are notoriously overcast. Researchers believe the students’ natural circadian clocks were being “pushed back” or delayed in winter because they were not getting enough exposure during the day to natural light, and that getting more daytime light exposure can help reverse this.

UW brings field geology to students with ‘Virtual Field Geology’
UW’s Virtual Field Geology project has many goals: to make geology field experiences accessible to more people; to document geological field sites that may be at risk from erosion or development; to offer virtual “dry run” experiences; and to allow scientific collaborators to do virtual visits to a field site together. While the pandemic brought new urgency to the project, its developers believe it’s part of a “new normal” for geology research and education.
