What’s for dinner? Scientists unearth key clues to cuisine of resident killer whales
Scientists have discovered the cuisine preferences of two resident killer whale populations, also known as orcas: the Alaska residents and the southern residents, which reside primarily in the Salish Sea and off the coast of Washington, British Columbia, Oregon and northern California. The two populations show broad preference for salmon, particularly Chinook, chum and coho. But they differ in when they switch to hunting and eating different salmon species, as well as the other fish species they pursue to supplement their diets. This information could aid conservation efforts for southern resident killer whales, which remain critically endangered due to pollution, loss of salmon habitat and other human-caused factors that disrupt their hunting and reproductive capabilities.

Explaining dramatic planetwide changes after world’s last ‘Snowball Earth’ event
Some of the most dramatic climatic events in our planet’s history are “Snowball Earth” events that happened hundreds of millions of years ago, when almost the entire planet was encased in ice up to 0.6 miles thick. New research from the University of Washington provides a more complete picture for how the last Snowball Earth event ended, and suggests why it preceded a dramatic expansion of life on Earth, including the emergence of the first animals.

UW researchers develop a stretchable, wearable device that lights up an LED using only the warmth of your skin
UW researchers have developed a flexible, durable electronic prototype that can harvest energy from body heat and turn it into electricity that can be used to power small electronics, such as batteries, sensors or LEDs. This device is also resilient — it still functions even after being pierced several times and then stretched 2,000 times.
Thanks to humans, Salish Sea waters are too noisy for resident orcas to hunt successfully
New research led by the University of Washington and the National Oceanic and Atmospheric Administration has revealed how underwater noise produced by humans may help explain why southern resident orca populations have not recovered from historic lows. In a paper published Sept. 10 in Global Change Biology, the team reports that underwater noise pollution — from both large and small vessels — forces northern and southern resident orcas to expend more time and energy hunting for fish. The din also lowers the overall success of their hunting efforts. Noise from ships likely has an outsized impact on southern resident orca pods, which spend more time in parts of the Salish Sea with high ship traffic.

Galaxies in dense environments tend to be larger, settling one cosmic question and raising others
A new study has found galaxies with more neighbors tend to be larger than their counterparts that have a similar shape and mass, but reside in less dense environments. In a paper published Aug. 14 in the Astrophysical Journal, the team, which used a machine-learning algorithm to analyze millions of galaxies, reports that galaxies found in denser regions of the universe are as much as 25% larger than isolated galaxies. The findings resolve a long-standing debate among astrophysicists over the relationship between a galaxy’s size and its environment, but also raise new questions about how galaxies form and evolve over billions of years.

How iBuyers are changing real estate racial disparities and individual homeownership rates in one major city
University of Washington researchers investigated how iBuyers — companies that use automated algorithms to quickly buy and sell homes — have affected the well-documented racial bias against Black home sellers. Looking at Mecklenburg County, North Carolina, they found that on average iBuyers paid more equal prices to Black and white home sellers than individual buyers, largely because iBuyers paid white sellers significantly less on average than an individual buyer. They also discovered that iBuyers were significantly more likely to resell homes to institutions, such as large rental companies that’ve been tied to high eviction rates and rent-gouging.

Wolves’ return has had only small impact on deer populations in NE Washington, study shows
Wolves returned to Washington state in 2008. A new study shows that, despite their rising numbers, wolves are not having much of an impact on white-tailed deer, one of their primary prey. In a paper published June 18 in Ecological Applications, scientists from the University of Washington and the Washington Department of Fish & Wildlife report that the biggest factor shaping white-tailed deer populations in northeast Washington is the quality of habitat available, which is largely determined by human activity. Cougars were second in their impact. Wolves were a distant third.
