Permanent Daylight Saving Time Would Reduce Deer-Vehicle Collisions, Study Shows

In much of the United States, there is a twice-yearly shift in timekeeping between standard time and daylight saving time, or DST, which delays both sunrise and sunset to make mornings darker and evenings brighter.

Endangered Fruit-Eating Animals Play An Outsized Role In A Tropical Forest — Losing Them Could Have Dire Consequences

A new study by researchers at the University of Washington shows that losing a particular group of endangered animals — those that eat fruit and help disperse the seeds of trees and other plants — could severely disrupt seed-dispersal networks in the Atlantic Forest, a shrinking stretch of tropical forest and critical biodiversity hotspot on the coast of Brazil.

These Female Hummingbirds Evolved To Look Like Males — Apparently To Evade Aggression

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.

New Study Challenges Old Views On What’s ‘Primitive’ In Mammalian Reproduction

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.

Top Predators Could ‘Trap’ Themselves Trying To Adapt To Climate Change, Study Shows

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.

Northern And Southern Resident Orcas Hunt Differently, Which May Help Explain The Decline Of Southern Orcas

In the Pacific Northwest and British Columbia, scientists have been sounding the alarm about the plight of southern resident orcas.

Human-Wildlife Conflicts Rising Worldwide With Climate Change

Research on the impacts of climate change often considers its effects on people separately from impacts on ecosystems.

Lasers Trigger Magnetism In Atomically Thin Quantum Materials

Researchers have discovered that light — in the form of a laser — can trigger a form of magnetism in a normally nonmagnetic material.

DNA Testing Exposes Tactics Of International Criminal Networks Trafficking Elephant Ivory

A team led by scientists at the University of Washington and special agents with the U.S.

Mosquitoes Are Seeing Red: Why New Findings About Their Vision Could Help You Hide From These Disease Vectors

Beating the bite of mosquitoes this spring and summer could hinge on your attire and your skin.

Hungry Yeast Are Tiny, Living Thermometers

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.

Fast, Cheap Test Can Detect COVID-19 Virus’ Genome Without Need For PCR

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.

Mass Die-Off Of Magellanic Penguins Seen During 2019 Heat Wave

In June 2021, an unprecedented heat wave hit the Pacific Northwest and Canada, killing an estimated 1,400 people.

Northern And Southern Resident Orcas Hunt Differently, Which May Help Explain The Decline Of Southern Orcas

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.

Human-Wildlife Conflicts Rising Worldwide With Climate Change

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 ‘Presses’ And ‘Pulses’ Impact Magellanic Penguins — A Marine Predator — With Guidance For Conservationists

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.”

Trouble Falling Asleep At Night? Chase That Daytime Light, Study Shows

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.

New Blood Test Can Detect ‘Toxic’ Protein Years Before Alzheimer’s Symptoms Emerge, Study Shows

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.
