A University of Washington-led study found that social status in rhesus macaques affected how the animals responded to stress.Noah Snyder-Mackler/U. of Washington

What social stress in monkeys can tell us about human health

Even though stress is a normal physical reaction, it can sometimes have negative effects on your health. It wears down the body and compromises the...
This illustration shows the percentage of marine animals that went extinct at the end of the Permian era by latitude, from the model (black line) and from the fossil record (blue dots). A greater percentage of marine animals survived in the tropics than at the poles. The color of the water shows the temperature change, with red being most severe warming and yellow less warming. At the top is the supercontinent Pangaea, with massive volcanic eruptions emitting carbon dioxide. The images below the line represent some of the 96 percent of marine species that died during the event.

Global warming wiped out 95% of marine life 252 million years ago

A new study by the University of Washington has suggested that extreme global warming caused Earth's biggest ever mass extinction. The largest extinction in Earth's history...
The peptides in this highly ordered two-dimensional array avoid the expected nucleation barrier by assembling in a row-by-row fashion.PNNL

Two-dimensional materials skip the energy barrier by growing one row at a time

Scientists at the University of Washington in collaboration with Department of Energy’s Pacific Northwest National Laboratory and University of California, Los Angeles- have created new...
Alzheimer's is not one disease but six different conditions

Alzheimer’s is not one disease but six different conditions

A new study that involves 19 researchers from several institutions, has suggested a new way to classify patients with Alzheimer's disease. The study suggests that Alzheimer's,...
The small, cool M dwarf star TRAPPIST-1 and its seven worlds. New research from the University of Washington speculates on possible climates of these worlds and how they may have evolved.NASA

New climate models of small star TRAPPIST 1’s seven intriguing worlds

In a new study, scientists are modeling atmospheres, not just assuming that the things we see in the solar system will look the same...

Scientists engineered a functional optical lens out of 2D materials

Ultrathin materials are increasingly replacing traditional thick glass lenses used today in cameras and imaging systems. These engineered lenses — known as metalenses, consist of materials constructed at...

Prescience: Helping doctors predict the future

Scientists at the University of Washington have developed a new machine-learning system, Prescience to predict the likelihood that a patient will develop hypoxemia — a...
Galápagos penguins

How to tell the sex of a Galápagos penguin?

Galápagos penguins are the only penguins to live in a tropical locale. Like all penguin species and most birds, they need outside genitalia. Moreover,...
