Biology

What is this thing called life? Biologists are life's detectives, discovering how life works and what makes animals, plants and microbes "alive." Organisms don't remain the same forever. Without change, life on Earth would stagnate. Species are in a constant dance with their environment. When an environment changes, the species that live within must change too, evolving to better adapt in order to survive. The end result is the diversity of life we see around us.

The role of the hippocampus in discerning memory

Without an intact hippocampus, forming new memories is impossible. Researchers from Arizona State University and Stanford University have found an equally important role for the hippocampus: feeding information to brain areas responsible for learning

Tomato crops hinge on adaptation and biodiversity

A team of researchers visits a seed bank, the Tomato Genetics Resource Center, where scientists try to preserve the genetic diversity available in wild tomato relatives and make it available for crop breeders

Crops versus wild

This video describes a food chain that extends from consumers, producers, breeders and the wild crop relatives that breeders depend on for crop improvement.

A whale of a ride

Barnacles are sticky little critters that hitch rides on the backs of humpback and gray whales. They hold a wealth of information that is helping scientists better understand how whales might respond to the current changes in Earth's climate

What you see is what you know

National Science Foundation-funded cognitive neuroscientists at George Washington University have found that a person's knowledge about the size of everyday objects impacts how our brains process and interact with the visual environment

How hard are these protein droplets?

University at Buffalo physicists are using innovative tools to study the properties of a bizarre class of molecules that may play a role in disease: proteins that cluster together to form spherical droplets inside human cells
