A UW Biology study finds Argentinian hunter-gatherers without electricity sleep longer than those with power.

Science confirms what we know to be true: Making a dude feel "feminine" is probably going to make him defensive

Department of Astronomy Professor Andrew Connolly discusses innovation, big data, and answering the biggest questions of the universe.

Four students who earned graduate degrees this year have been named A&S Graduate Medalists for 2015.

Researcher from the UW's Virtual Planetary Laboratory asks "what does life look like on other planets?"

New University of Washington research finds that men who believe they fall short of those ideals might be prompted to reassert their masculinity in small but significant ways.

The root cause of why we get less sleep now than our ancestors could come down to a very simple reason: artificial light.

To stop elephant slaughter in Africa, zoologist Sam Wasser spent years extracting DNA from elephant dung and tissue. Much of the world's poached ivory, he discovered, comes from just three places.

UW biologist Samuel Wasser's pioneering work is helping stop illegal ivory trade that's decimating the African elephant population.

Biologists estimate the business kills roughly one out of every ten African elephants each year.

Most illegally poached African elephant ivory can be traced back to just two areas of Africa, research shows.

The key to saving elephants from poachers could be locked up in the animals' DNA, according to the results of a new study.

Most illegal ivory comes from animals killed in two areas in Africa: Tanzania and a protected area that spans Gabon, Republic of Congo, Cameroon and the Central African Republic.

Investigators who collected DNA from the tusks of slain elephants have identified two large areas where the slaughter has been occurring

Biology Professor Keiko Torii and her team have identified a mechanism that some plant cells use to receive complex and contradictory messages from their neighbors.
