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.

Gecko's latest superpower revealed

Geckos are renowned for their acrobatic feats on land and in the air, but a new discovery that they can also run on water puts them in the superhero category, says a University of California, Berkeley, biologist

Burst of morning gene activity tells plants when to flower

An international team of researchers has discovered that the gene FT -- the primary driver of the transition to flowering in plants each spring -- does something unexpected in Arabidopsis thaliana plants grown in natural environments, with implications for the artificial growing conditions scientists commonly used in the lab
