Life Sciences

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.

How wood frogs survive extreme temperatures

Freezing feats of wood frogs. University of Alaska Fairbanks graduate student Don Larson and UAF Institute of Arctic Biology Director Brian Barnes search for Alaska wood frogs for their research project on extreme temperature survival.

Forest plant genetics

Matias Kirst, an associate professor in quantitative genetics at the University of Florida, explains how researchers study tree genetics to identify species best suited for forest plantations and those able to adapt to climate change.

The blanc conundrum

The siphonophore Hippopodius hippopus is usually transparent, but when disturbed it suddenly becomes milky white.

Crab research

Gustav Paulay, curator of marine malacology at the Florida Museum of Natural History, talks about larval crab development and how DNA analysis and comparisons of larval and adult crabs helps increase our understanding of different crab species.

Frozen fruit bats

NSF Science Now: Episode 24

In this week's episode we discover secrets in buried soils. We learn how elephant seals protect their organs when diving. We learn about Amulet- the future in wearable technology and finally we explore the fast-moving Thwaites glacier in Antarctica.

Two urchins

The green urchin and the pencil urchin are alike in many ways, but their differences matter in a big way when it comes to their ecological impacts.

Evolutionary ecology

Evolutionary ecologist, Christine Miller, studies the relationship between insects' genes and environment
