Here in what is called the Anthropocene era, humans and our urban environments appear to be driving accelerated evolutionary change in plants, animals, fungi, viruses and more — changes that could affect key ecosystem functions and thus human well-being. These interactions between evolution and ecology are called “eco-evolutionary feedback.” The National Science Foundation has awarded a five-year, $500,000 grant to a multi-institution research network team headed by Marina Alberti, University of Washington professor of urban design and planning, to advance…

A study by an international team of researchers, including from the University of Washington, determines that carved stone tools, also known as Levallois cores, were used in Asia 80,000 to 170,000 years ago. With the find — and absent human fossils linking the tools to migrating populations — researchers believe people in Asia developed the technology independently, evidence of similar sets of skills evolving throughout different parts of the ancient world.

To better understand how state governments across the United States execute their diverse responsibilities, look at their internet footprint, says a new study by researchers at the University of Washington, Harvard University, and Northeastern University.

Researchers from the University of Washington have shown how Magellanic penguins fare during the winter months when they spend months at sea feeding. They have discovered that oceanographic features are more likely to negatively impact the body conditions of Magellanic penguin females, but not males, when the penguins return to their nesting grounds in spring.

A study led by the University of Washington is the first large-scale trial of hundreds of PTSD patients, including veterans and survivors of sexual assault, to measure whether patient preference in the course of treatment impacts the effectiveness of both cognitive behavioral therapy and use of selective serotonin reuptake inhibitors, a type of antidepressant often prescribed for PTSD.

Researchers at the University of Washington have developed a new machine-learning system, called Prescience, which uses input from patient charts and standard operating room sensors to predict the likelihood that a patient will develop hypoxemia — a condition when blood oxygen levels dip slightly below normal. Prescience also provides real-world explanations behind its predictions.

Engineers at the University of Washington have developed 3D printed devices that can track and store their use — without using batteries or electronics. Instead, this system uses a method called backscatter, through which a device can share information by reflecting signals that have been transmitted to it with an antenna.

A new study led by the University of Washington found that while dead whales are valuable sources of fat and protein for some polar bears, this resource will likely not be enough to sustain most bear populations in the future when the Arctic becomes ice-free in summers.

A new analysis that uses high-resolution data for 24 ocean regions in Africa, Europe, North and South America and Australasia shows that 14 percent of the overall seafloor shallower than 1,000 meters (3,280 feet) is trawled. The paper shows that the footprint of bottom-trawl fishing on continental shelves and slopes across the world’s oceans often has been substantially overestimated.

A new book by University of Washington history professor George Behlmer seeks to improve understanding of the British colonial era by “reconsidering the conduct of islanders and the English-speaking strangers who encountered them.”

Former Interior Secretary Sally Jewell brings a lifetime of experience in business, nonprofits, government and the outdoors to the University of Washington, where one of her tasks is to help shape the future of EarthLab, a new university-wide institute that seeks to connect scholars with community partners to solve our most difficult environmental problems.

When levels of carbon dioxide in the atmosphere rise, most plants do something unusual: They thicken their leaves. Now two University of Washington scientists have shown that this reaction by plants will actually worsen climate change by making the global “carbon sink” contributed by plants was less productive.

  For more than 2 million years, the native forests on the Pacific islands of Guam and Rota were home to several thousand crows, members of a species found nowhere else on Earth. But over the last 60 years, the Mariana crow — called the Aga in the Chamorro language — has completely disappeared from the island of Guam and rapidly declined on neighboring Rota. Today there are only about 175 Aga left in the wild. To ensure the survival…

A substantial gift from Lynn and Howard Behar will expand the University of Washington School of Social Work’s support for the next generation of oncology social work scholars by providing funds to launch a new Center for Integrative Oncology and Palliative Care Social Work.

The Center will take a social justice approach to oncology and palliative care services, with a commitment to addressing documented health disparities in cancer and end-of-life care based on race and ethnicity, disability, gender and sexual identity, geographic location, income or education.

For angiosperms — or flowering plants — one of the most important decisions facing them each year is when to flower. It is no trivial undertaking. To flower, they must cease vegetative growth and commit to making those energetically expensive reproductive structures that will bring about the next generation. Knowledge of this process at the cellular level is critical for understanding how plants allocate resources and produce the components we care most about — including the grains, tubers, leaves, nuts…

The international trade in elephant ivory has been illegal since 1989, yet African elephant numbers continue to decline. In 2016, the International Union for Conservation of Nature cited ivory poaching as a primary reason for a staggering loss of about 111,000 elephants between 2005 and 2015 — leaving their total numbers at an estimated 415,000. For media Download soundbites, b-roll and images In a paper published Sept. 19 in the journal Science Advances, an international team led by scientists at…

Margaret O’Mara, UW professor of history, explores the impact of a December 1968 computer presentation that came to be called “the mother of all demos” in an essay and podcast from the news website The Conversation.

Rapid deoxygenation in the Gulf of St. Lawrence is caused by shifts in two of the ocean’s most powerful currents: the Gulf Stream and the Labrador Current. A detailed model shows that large-scale climate change is causing oxygen to drop in the deeper parts of this biologically rich waterway.

The share of Washingtonians living below the federal poverty threshold declined slightly from 11.3 percent to 11 percent between 2016 and 2017, according to new Census data released Thursday. While this change was not statistically significant, the 2017 poverty rate remains below the post-recession high of 14.1 percent in 2013. Washington was one of 28 states and the District of Columbia where poverty rates remained statistically unchanged from the prior year. During that period, poverty rates declined in 20 states…

When Tony Greenwald and his colleagues developed the online Implicit Association Test two decades ago, it enjoyed quick success in the pre-laptop, pre-smartphone, nascent Internet world, with some 45,000 participants in the first month. The test, which requires classifying words and images rapidly according to their meanings, captures unconscious biases toward — depending on the test version — race, gender, age and dozens of other traits and preferences. Since its debut in 1998, the test has been taken online more…
