For the past decade and a half, a crew of about 20 entomologists, water ecologists, and other specialists converges on the shorelines of Mongolia’s lakes, rivers, and streams, just when swarms of aquatic insects do the same.
Satellite imagery is giving biologists a whole new perspective on the phenomena they study.
Yeast selected to settle more quickly through a test tube evolved into multicellular, snowflake-like clusters in just 2 weeks, or about 100 generations. The clusters evolved to be larger, produce multicellular progeny, and even show differentiation o
In July 1587, a British colonist named John White accompanied 117 people to settle a small island sheltered within the barrier islands of what would become North Carolina’s Outer Banks. When conditions proved harsher than anticipated, White agreed to
Not all inflammation leads to pain. Despite widespread infection followed by fever, colds rarely cause pain. But when some cytokines and certain immune cells are active near pain-sensing nerves, they trigger receptors that convey pain sensations to t
In its brief, 4-year history, The Scientist’s annual Top 10 Innovations contest has become a showcase of the coolest life science tools to emerge in the previous year. This year’s installment is no exception.
