White-necked jacobin hummingbirds sport a colorful blue-and-white plumage as juveniles. When they grow into adulthood, males retain this dazzling pattern, while females develop a more “muted” palette of green and white — at least, most females. Curiously, about 20% of females defy the norm and retain male-like plumage into adulthood.
It’s hard to imagine life on Earth without mammals. They swim in the depths of the ocean, hop across deserts in Australia and travel to the moon.
As climate change alters environments across the globe, scientists have discovered that in response, many species are shifting the timing of major life events, such as reproduction.
In the Pacific Northwest and British Columbia, scientists have been sounding the alarm about the plight of southern resident orcas.
Research on the impacts of climate change often considers its effects on people separately from impacts on ecosystems.
Researchers have discovered that light — in the form of a laser — can trigger a form of magnetism in a normally nonmagnetic material.

Beating the bite of mosquitoes this spring and summer could hinge on your attire and your skin.
Membranes are crucial to our cells. Every cell in your body is enclosed by one. And each of those cells contains specialized compartments, or organelles, which are also enclosed by membranes.
Researchers at the University of Washington have developed a new test for COVID-19 that combines the speed of over-the-counter antigen tests with the accuracy of PCR tests that are processed in medical labs and hospitals.
In June 2021, an unprecedented heat wave hit the Pacific Northwest and Canada, killing an estimated 1,400 people.
In the Pacific Northwest and British Columbia, scientists have been sounding the alarm about the plight of southern resident orcas. Annual counts show that population numbers, already precarious, have fallen back to mid-1970s levels. Most pregnancies end in miscarriage or death of the newborn. They may not be catching enough food.
Research on the impacts of climate change often considers its effects on people separately from impacts on ecosystems. But a new study is showing just how intertwined we are with our environment by linking our warming world to a global rise in conflicts between humans and wildlife.
Climate change will reshape ecosystems worldwide through two types of climate events: short-term, extreme events — like a heat wave — and long-term changes, like a shift in ocean currents. Ecologists call the short-term events “pulses,” and the long-term changes “presses.”
A study measuring the sleep patterns of students at the University of Washington has turned up some surprises about how and when our bodies tell us to sleep — and illustrates the importance of getting outside during the day, even when it’s cloudy.
Today, by and large, patients receive a diagnosis of Alzheimer’s only after they exhibit well-known signs of the disease, such as memory loss. By that point, the best treatment options simply slow further progression of symptoms.
