Some polar bears in far north are getting short-term benefit from thinning ice
The small subpopulation of polar bears in Kane Basin were doing better, on average, in recent years than in the 1990s. The bears are experiencing short-term benefits from thinning and shrinking multiyear sea ice that allows more sunlight to reach the ocean surface, which makes the system more ecologically productive.

Most landslides in western Oregon triggered by heavy rainfall, not big earthquakes
Researchers at the University of Washington, Portland State University and the University of Oregon have shown that deep-seated landslides in the central Oregon Coast Range are triggered mostly by rainfall, not by large offshore earthquakes. The open-access paper was published Sept. 16 in Science Advances. “Geomorphologists have long understood the importance of rainfall in triggering…
Marine animals live where ocean is most ‘breathable,’ but ranges could shrink with climate change
New research shows that a wide variety of marine animals — from vertebrates to crustaceans to mollusks — already inhabit the maximum range of breathable ocean that their physiology will allow. The findings provide a warning about climate change: Since warmer waters will harbor less oxygen, some stretches of ocean that are breathable today for a given species may not be in the future.

Frequently asked questions: torpor in Antarctic Lystrosaurus
This FAQ discusses evidence for a hibernation-like condition in Lystrosaurus, a mammal relative that lived in the Antarctic portion of Pangea about 250 million years ago. This discovery was enabled by high-resolution of incremental growth marks preserved in the tusks of Lystrosaurus.
Weathering the tough times: Fossil evidence of ‘hibernation-like’ state in 250-million-year-old Antarctic animal
University of Washington scientists report evidence of a hibernation-like state in Lystrosaurus, an animal that lived in Antarctica during the Early Triassic, some 250 million years ago. The fossils are the oldest evidence of a hibernation-like state in a vertebrate, and indicate that torpor — a general term for hibernation and similar states in which animals temporarily lower their metabolic rate to get through a tough season — arose in vertebrates even before mammals and dinosaurs evolved.

Mount Everest summit success rates double, death rate stays the same over last 30 years
A new study led by researchers at the University of Washington and the University of California, Davis, finds that the success rate of summiting Mount Everest has doubled in the last three decades, even though the number of climbers has greatly increased, crowding the narrow route through the dangerous “death zone” near the summit. However, the death rate for climbers has hovered unchanged at around 1% since 1990.

Failure to ‘flatten the curve’ may kill more people than we thought
New research by the University of Minnesota and the University of Washington finds that every six additional ICU beds or seven additional non-ICU beds filled by COVID-19 patients leads to one additional COVID-19 death over the following week. “A spike in hospitalization naturally leads to more deaths, but these deaths may not only come from…

Data omission in key EPA insecticide study shows need for review of industry analysis
For nearly 50 years, a statistical omission tantamount to data falsification sat undiscovered in a critical study at the heart of regulating one of the most controversial and widely used pesticides in America. Chlorpyrifos, an insecticide created in the late 1960s by the Dow Chemical Co., has been linked to serious health problems, especially in children….

New studies show how to save parasites and why it’s important
An international group of scientists has laid out an ambitious global conservation plan for parasites. A related paper led by the University of Washington found that responses of parasites to environmental change are likely to be complex, and that a changing world probably will see both outbreaks of some parasites and a total loss of other parasite species.

Deep-sea anglerfishes have evolved a new type of immune system
Deep-sea anglerfishes employ an incredible reproductive strategy. Tiny dwarfed males become permanently attached to relatively gigantic females, fuse their tissues and then establish a common blood circulation. Now scientists have figured out why female anglerfishes so readily accept their male mates. Their findings are published July 30 in Science.

Passing crucial, challenging introductory chemistry course gives biggest boost to underrepresented students
Researchers examined 15 years of records of student performance, education and demographics for chemistry courses at the University of Washington. They found that underrepresented students received lower grades in the general chemistry series compared to their peers and, if the grade was sufficiently low, were less likely to continue in the series and more likely to leave STEM. But if underrepresented students completed the first general chemistry course with at least the minimum grade needed to continue in the series, they were more likely than their peers to continue the general chemistry series and complete this major step toward a STEM degree.

Researchers use brain imaging to demonstrate weaker neural suppression in individuals with autism
In a paper published May 29 in Nature Communications, a team of scientists at the University of Washington, the University of Minnesota and the Johns Hopkins University reports that differences in visual motion perception in autism spectrum disorder are accompanied by weaker neural “suppression” in the visual cortex of the brain, which may help scientists understand sensory hypersensitivity in people with ASD.

Cosmic bursts unveil universe’s missing matter
An international team of astronomers has used mysterious fast radio bursts to solve a decades-old mystery of “missing matter,” material long predicted to exist in the universe but never detected — until now. The researchers have now found all of the missing “normal” matter in the vast space between stars and galaxies. The team, which includes scientists based in Australia, the United States and Chile, announced its findings in a paper published May 27 in the journal Nature.

Ocean ‘breathability’ key to past, future habitat of West Coast marine species
Historical observations collected off California since the 1950s suggest that anchovies thrive where the water is breathable — a combination of the oxygen levels in the water and the species’ oxygen needs, which are affected by temperature. Future projections suggest that the waters off Mexico and Southern California could be uninhabitable by 2100.
