The red streaks crisscrossing the surface of Europa, one of Jupiter’s moons, are striking. Scientists suspect it is a frozen mixture of water and salts, but its chemical signature is mysterious because it matches no known substance on Earth.
An international team led by the University of Washington may have solved the puzzle with the discovery of a new type of solid crystal that forms when water and table salt combine in cold and high-pressure conditions.
In recent years, the idea of life on other planets has become less far-fetched. NASA announced June 27 that it will send a vehicle to Saturn’s icy moon Titan, a celestial body known to harbor surface lakes of methane and an ice-covered ocean of water, boosting its chance for supporting life.
On Earth, scientists are studying the most extreme environments to learn how life might exist under completely different settings, like on other planets.
At the base of the Transantarctic Mountains lies a geological oddity. Don Juan Pond is one of the saltiest bodies of water on the planet, filled with a dense, syrupy brine rich in calcium chloride that can remain liquid to minus 50 degrees Celsius, far below the freezing point of water. But the source of water and salt to this unusual pond remains a mystery — even as hints emerge that water in a similar form could exist on Mars.
By adding salt to marine clouds — called cloud brightening — scientists think we may be able to tame growing hurricanes and stop others from happening. Atmospheric Sciences’ Rob Wood is quoted. Read more here.
In 2017, nearly half the population of Umtanum Desert buckwheat (Eriogonum codium) was destroyed by a wildfire in Washington’s Hanford Reach National Monument. This unassuming perennial plant is not found anywhere else in the world — meaning catastrophic events such as this could eventually spell extinction for its corner of Washington’s rich biodiversity.
How do we protect rare, endemic plants as they come under increasing pressure from intensifying wildfires and habitat disruption?
Researchers from the University of Washington and the University of California, Berkeley have conducted experiments that measured the physical limits for the existence of liquid water in icy extraterrestrial worlds. This blend of geoscience and engineering was done to aid in the search for extraterrestrial life and the upcoming robotic exploration of oceans on moons of other planets.
The results were recently published in Cell Reports Physical Sciences.
One of the facts of life for humans is the replacement of baby teeth with permanent adult teeth. Whether pulled out prematurely, wiggled loose by eager hands or naturally falling out unexpectedly, this occasion marks an important milestone in the maturation process that is shared amongst all vertebrates in some form.
Imagine, though, losing and replacing a tooth every single day.
University of Washington oceanographer Parker MacCready is one of 59 new fellows elected this year by the American Geophysical Union. The scientific organization recognizes only 1 in 1,000 of its members as global leaders and experts who have propelled our understanding of the geosciences.
MacCready, a professor in the UW School of Oceanography, was recognized for his work to advance fundamental understanding of ocean coasts and estuaries, or marine environments where freshwater and saltwater mix.
Friday Harbor Laboratories (FHL) recently established the Friday Harbor Laboratories Ocean Observatory (FHLOO), vastly expanding their capabilities to collect and share real-time data about the surrounding marine environment. Connected to the larger Northwest Association of Networked Ocean Observing Systems (NANOOS), FHLOO takes continuous seawater measurements such as salinity, temperature, CO2, oxygen and chlorophyll, in addition to monitoring microplankton. While the system has been taking measurements since the summer of 2020, the ability to live-stream its data is new, providing a window into the Salish Sea accessible to researchers, students and the public.

Jump in and get your hands dirty with field work or learn how to communicate about complex environmental issues—we have something for everyone. These courses have no prereqs and are open to all majors.
How do environmental scientists unearth new discoveries about our planet? Many of us might imagine scientists observing the world around them, wading through tide pools or digging up soil. But what about questions surrounding the origins of life on Earth, or questions about microbes deep, deep within the ocean? Big questions like these require big investments, and the Simons Foundation is supporting University of Washington (UW) researchers to find some of the answers.
Sailing into Friday Harbor, you can’t miss the set of long, low-slung buildings along the water’s northern edge. They are home to the famed Friday Harbor Laboratories (FHL), a research outpost housed within the larger University of Washington College of the Environment. The labs have operated over one hundred years, first gaining notoriety for their impact in evolutionary and neuroscience. Over the decades, the labs have added marine ecology, seawater chemistry, biomechanics and all flavors of oceanography to their research repertoire.
When looking at a periodic table, potassium might not be the first element you’re drawn to – distracted instead by gold, copper or silver. But a new paper published in Science Advances suggests we should be paying more attention to this abundant substance.
The study – with first author Yan Hu, a recent graduate student and postdoctoral researcher in the UW Department of Earth and Space Sciences and now at Institut de Physique du Globe de Paris – advances our ability to trace potassium isotopes at high precision, unleashing a suite of potential applications ranging from measuring past climates to further understanding ocean chemistry.
You might not know it, but danger for saltwater plants and animals lurks on every single beach — from the white sand beaches of the Caribbean to the rockier beaches found along the Washington coastline, and every beach in between. Plastic debris and other trash left behind by beachgoers ends up in the sand and water, eventually making their way into the stomachs or around the necks of our favorite marine animals.
The UW College of the Environment is pleased to announce that Megan Dethier has agreed to serve as director of the Friday Harbor Laboratories, effective May 1, 2020 through June 30, 2022. Dethier has been serving as the Interim Director of Friday Harbor Laboratories.
Dethier is a research professor in the Biology Department at the University of Washington and works full-time at the College’s Friday Harbor Laboratories on San Juan Island.
