Reaching for neutron stars

A cross-disciplinary team from chemistry and physics in Arts & Sciences at Washington University in St. Louis has discovered both a framework to predict where neutrons will inhabit a nucleus and a way to predict the skin thickness of a nucleus.

Oxygen levels link to ancient explosion of life

A team of researchers, including a faculty member and postdoctoral fellow from Washington University, found that oxygen levels appear to increase at about the same time as a three-fold increase in biodiversity during the Ordovician Period, between 445 and 485 million years ago, according to a study published Nov. 20 in Nature Geoscience.

Water world

Three Washington University in St. Louis scientists studied the great granddaddy of all photosynthetic organisms — a strain of cyanobacteria — to develop the first experimental map of that organism’s water world.
Barley continues to be the staple diet of people living in this Dolpo Valley of Nepal, a harsh environment at 4.000 meters above sea level.

How barley reached China: A story of food globalization

First domesticated 10,000 years ago in the Fertile Crescent of the Middle East, wheat and barley took vastly different routes to China, with barley switching from a winter to both winter and summer crop during a thousand-year detour along the southern Tibetan Plateau, suggests new research from Washington University in St. Louis.

Bear or chipmunk? Engineer finds how brain encodes sounds

When you are out in the woods and hear a cracking sound, your brain needs to process quickly whether the sound is coming from, say, a bear or a chipmunk. In new research published in PLoS Biology, a biomedical engineer at Washington University in St. Louis has a new interpretation for an old observation, debunking an established theory in the process.
