Record-high Arctic freshwater will flow through Canadian waters, affecting marine environment and Atlantic ocean currents
The Arctic Ocean’s Beaufort Sea has increased its freshwater content by 40% over the past two decades. When conditions change this freshwater will travel to the Labrador Sea off Canada, rather than through the wider marine passageways that connect to seas in Northern Europe. This has implications for local marine environments and global ocean circulation.
Scientists describe earliest primate fossils
A new study published Feb. 24 in the journal Royal Society Open Science documents the earliest-known fossil evidence of primates. These creatures lived less than 150,000 years after the Cretaceous-Paleogene mass extinction event that killed off non-avian dinosaurs and saw the rise of mammals.

Logging change in Puget Sound: Researchers use UW vessel logbooks to reconstruct historical groundfish populations
To understand how Puget Sound has changed, we first must understand how it used to be. But unlike most major estuaries in the U.S., long-term monitoring of Puget Sound fish populations did not exist until 1990. Now researchers have discovered an unconventional method to help fill in gaps in the data: old vessel logbooks.

In Brazil, many smaller dams disrupt fish more than large hydropower projects
A new University of Washington paper quantifies the tradeoffs between hydroelectric generation capacity and the impacts on river connectivity for thousands of current and projected future dams across Brazil. The findings confirm that small hydropower plants are far more responsible for river fragmentation than their larger counterparts due to their prevalence and distribution.
On nights before a full moon, people go to bed later and sleep less, study shows
Sleep cycles in people oscillate during the 29.5-day lunar cycle: In the days leading up to a full moon, people go to sleep later in the evening and sleep for shorter periods of time. The team, led by researchers at the University of Washington, observed these variations in both the time of sleep onset and the duration of sleep in urban and rural settings — from Indigenous communities in northern Argentina to college students in Seattle, a city of more than 750,000. They saw the oscillations regardless of an individual’s access to electricity, though the variations are less pronounced in individuals living in urban environments.
Purported phosphine on Venus more likely to be ordinary sulfur dioxide, new study shows
A University of Washington-led team has revisited and comprehensively reinterpreted the radio telescope observations underlying a widely reported 2019 claim that phosphine gas was present in the atmosphere of Venus. In a paper accepted to the Astrophysical Journal, they report that sulfur dioxide, a common gas in the atmosphere of Venus, is likely what was detected instead of phosphine.

Astronomers document the rise and fall of a rarely observed stellar dance
Astronomers have catalogued 126 years of changes to a binary star system called HS Hydrae. Analyzing observations from astro-photographic plates in the late 1800s to TESS observations in 2019, they show that the two stars in HS Hydrae began to eclipse each other starting around a century ago, peaking in the 1960s. The degree of eclipsing then plummeted over the course of just a half century, and will cease around February 2021.
Sexual harassment claims considered more credible if made by ‘prototypical’ women
A new UW study reveals people’s perceptions that sexual harassment primarily affects young, feminine and conventionally attractive women. Women who fall outside that prototype not only are perceived as unharmed by harassment, but also have a harder time convincing others that they have been harassed.
