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.

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.

Jeff Lin (2012), obsessed with video games as a child, now leads teams of game developers at Horizon Metaverse — with the help of his UW PhD in psychology.

The College of Engineering and the College of Arts & Sciences researchers are helping to establish the UW as a global leader of the coming quantum age.

Learn about the sleep scientist and UW professor of biology, Horacio de la Iglesia, whose influential sleep research helped demonstrate the benefits of delaying school start times for Seattle high schoolers. Read writer Nicole Reeve-Parker's Faculty Friday, Spotlight.

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 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.

In a study published Dec. 8 in Nature Astronomy, an international research team, led by Orsola De Marco of Macquarie University in Sydney, Australia, analyzed 10 highly detailed exposures taken by the JWST of the Southern Ring Nebula. Their calculations show the central star that ejected the expanding nebula gas was originally three times the mass of the sun, and that unseen companions shaped the nebula's intricate features.

Astronomers at the DiRAC Institute have been preparing for a flood of data from the new Rubin Observatory. Now undergrads have joined the effort.

After committing to a new biology building in 2010, years of planning, relocation, and construction have culminated in the newly constructed greenhouse, and its doors are almost ready to open again. Taking the place of the old Botany Greenhouse, demolished in 2016, the new structure is located within the Life Sciences Building and, starting Dec. 1, will be open to the public on Thursdays from noon to 4 p.m.

A study led by Thure Cerling, a professor at the University of Utah, and co-authored by Sam Wasser, a University of Washington professor of biology, used carbon isotope science to show that tusks from a guarded government stockpile in Burundi have somehow made their way into the hands of illegal ivory traders.

A new study by researchers at the University of Washington shows that losing a particular group of endangered animals — those that eat fruit and help disperse the seeds of trees and other plants — could severely disrupt seed-dispersal networks in the Atlantic Forest, a shrinking stretch of tropical forest and critical biodiversity hotspot on the coast of Brazil.

A research team led by UW Electrical & Computer Engineering and UW physics professor Mo Li has developed a method of using soundwaves to move excitons farther than previously thought possible. This allows them to be used to create transistors, switches, and transducers — leading to faster and more energy-efficient computing and optical devices.
