Discovery of organic compounds bolsters case that Saturn’s moon Enceladus could support life
A new analysis of data from the Cassini space probe has identified organic compounds within jets of water ice erupting from Saturn’s moon Enceladus. Some of the compounds, which likely originated in Enceladus’ subsurface ocean, have never before been identified on another world beyond Earth. The study, conducted in part by a UW researcher, contributes to mounting evidence that Enceladus could support life.

More bees please: 8 new-to-Washington species identified
Bee experts wouldn’t have previously expected to find the likes of Osmia cyaneonitens, Dufourea dilatipes and Stelis heronae in Washington. But this year, while collecting pollinators in Chelan County to study how climate and wildfires affect native bee populations, Autumn Maust, a University of Washington research scientist of biology, discovered eight bee species never recorded in Washington.
Longer body size means more female calves for baleen whale moms
University of Washington researchers found, in historical whaling data, that longer baleen whale mothers were more likely to birth female calves than males. These results run contrary to a leading evolutionary theory that suggests that fit mothers will benefit more from male offspring.

This common fish has an uncommon feature: Forehead teeth, used for mating
New findings call into question one of the core assumptions about teeth. Adult male spotted ratfish, a shark-like species native to the eastern Pacific Ocean, have rows of teeth on top of their heads, lining a cartilaginous appendage called the tenaculum, in addition to those in their jaws. They used their tenaculum teeth to grip females while mating in water.

Study projects that increasing wildfires in Canada and Siberia will actually slow global warming
A new University of Washington–led study projects that in the next 35 years increasing boreal fires will actually slow global warming by 12% globally and 38% in the Arctic. Because the aerosols in smoke reflect more sunlight and make clouds brighter, summer temperatures during fire season drop, leading to reduced sea ice loss and cooler winter temperatures.
Iron from coal, steel industries alters North Pacific ecosystem

Atlantic Ocean current expected to undergo limited weakening with climate change, study finds
The Atlantic Meridional Overturning Circulation, or AMOC, is a system of ocean currents that plays a crucial role in regulating Earth’s climate by transporting heat from the Southern to Northern Hemisphere. Climate models have long predicted that global warming will cause the AMOC to weaken, with some projecting what amounts to a near-collapse relative to the AMOC strength in observations today. But a new study from a team of researchers that included the University of Washington shows that the AMOC is likely to weaken to a much lesser extent than current projections suggest.

Whale poop contains iron that may have helped fertilize past oceans
A recent theory proposes that whales weren’t just predators in the ocean environment: Nutrients that whales excreted may have provided a key fertilizer to these marine ecosystems. Research led by University of Washington oceanographers finds that whale excrement contains significant amounts of iron, a vital element that is often scarce in ocean ecosystems, and nontoxic forms of copper, another essential nutrient that in some forms can harm life.

Q&A: How rate of CO2 rise can affect a global ocean current
How fast the level of atmospheric carbon dioxide — and with it, the temperature — goes up matters for the ability of humans and ecosystems to adjust. A slower increase gives humans time to move away from low-lying coasts and animals time to move to new habitats. It turns out the rate of that increase matters for non-living systems, too. Camille Hankel, a postdoctoral researcher at the Cooperative Institute for Climate, Ocean and Ecosystem Studies, talks about her research on the Atlantic Ocean circulation.

Surveys show full scale of massive die-off of common murres following the ‘warm blob’ in the Pacific Ocean
Colony surveys of common murres, an Alaskan seabird, show the full effects of the 2014-16 marine heat wave known as “the blob.” Analysis of 13 colonies surveyed between 2008 and 2022 finds that colony size in the Gulf of Alaska dropped by half after the marine heat wave. In colonies along the eastern Bering Sea, west of the peninsula, the decline was even steeper, at 75% loss. No recovery has yet been seen.

Record-low Antarctic sea ice can be explained and forecast months out by patterns in winds
University of Washington researchers show that the all-time record low in winter sea ice extent in 2023 can be explained by warm Southern Ocean conditions and patterns in the winds that circled Antarctica months earlier, allowing forecasts for sea ice coverage around the South Pole to be generated six or more months in advance. This could support regional and global weather and climate models.

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.
