New circuit boards can be repeatedly recycled
A team led by researchers at the University of Washington developed a new PCB that performs on par with traditional materials and can be recycled repeatedly with negligible material loss. Researchers used a solvent that transforms a type of vitrimer — a cutting-edge class of polymer — into a jelly-like substance without damage, allowing solid components to be plucked out for reuse or recycling. With these “vPCBs” (vitrimer printed circuit boards), researchers recovered 98% of the vitrimer and 100% of the glass fiber.

Ice age climate analysis reduces worst-case warming expected from rising CO2
A detailed reconstruction of climate during the most recent ice age, when a large swath of North America was covered in ice, provides information on the relationship between CO2 and global temperature. Results show that while most future warming estimates remain unchanged, the absolute worst-case scenario is unlikely.

Q&A: How claims of anti-Christian bias can serve as racial dog whistles
A new University of Washington study showed that white and Black Christians perceived a politician concerned about anti-Christian bias as caring more about anti-white bias, being more willing to fight for white people and as less offensive than one concerned about anti-white bias.

New report ‘braids’ Indigenous and Western knowledge for forest adaptation strategies against climate change
Forests could also be potential bulwarks against climate change. But, increasingly severe droughts and wildfires, invasive species, and large insect outbreaks — all intensified by climate change — are straining many national forests and surrounding lands. A report by a team of 40 experts outlines a new approach to forest stewardship that “braids together” Indigenous knowledge and Western science to conserve and restore more resilient forestlands. Published March 25, the report provides foundational material to inform future work on climate-smart adaptive management practices for USDA Forest Service land managers.

Everyday social interactions predict language development in infants
In a study published April 8 in Current Biology, University of Washington researchers found that when the adult talked and played socially with a 5-month-old baby, the baby’s brain activity particularly increased in regions responsible for attention — and the level of this type of activity predicted enhanced language development at later ages.

Q&A: The growing trend of environmental, social and governance assurances in corporate America
Voluntary reports that discuss environmental, social and governance issues — or ESG issues — have become a major trend in corporate America over the past decade. Shawn Shi, University of Washington assistant professor of accounting in the Foster School of Business, is conducting ongoing research on the topic.

What four decades of canned salmon reveal about marine food webs
University of Washington researchers have shown that levels of anisakid worms — a common marine parasite — rose in two salmon species in the Gulf of Alaska and Bristol Bay over a 42-year period. The team discovered this by studying salmon caught, killed and canned from 1979 to 2021. Since anisakid worms have a complex life cycle involving multiple types of hosts, the researchers interpret their rising numbers as a potential sign of ecosystem recovery, possibly driven by rising numbers of marine mammals thanks to the 1972 Marine Mammal Protection Act.

Signs of life detectable in single ice grain emitted from extraterrestrial moons
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.

Citizen scientist group finds 15 rare ‘active asteroids’
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 University of Washington 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.

Scientists CT-scanned thousands of natural history specimens, which you can access for free
Natural history museums have entered a new stage of discovery and accessibility — 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 University of Washington 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.

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.”

How will climate change affect how predators hunt prey? Two UW professors teamed up to find out
Two UW 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.
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.
