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 rocks move

Thin sheets of ice push rocks across the desert when conditions are just right

Parasitic plant timelapse

This video shows the relationship between a parasitic plant, dodder, and two host plants, Arabidopsis and tomatoes.

C-DEBI

The mission of C-DEBI is to explore life beneath the seafloor and make transformative discoveries that advance science, benefit society, and inspire people of all ages and origins.

Surprising new role for calcium in sensing pain

Researchers have made a surprising discovery in worms about the role of calcium in pain signaling. They have built a structural model of the molecule that allows calcium ions to pass into a neuron, triggering a signal of pain. These discoveries may help direct new strategies to treat pain in people.

Why Science: forestry

In this video, University of Florida professor Tim Martin explains his work in the woods.

Jellyfish swarms and environmental change

Jellyfish swarms in the Gulf of Mexico help researchers identify environmental changes in the water. Dr. Monty Graham at the University of Southern Mississippi studies these massive jellyfish swarms that can stretch for many, many miles.

Quest field notes: Dan Costa in Antarctica

In this video, Professor Costa describes his work studying the winter foraging ecology of weddell seals in Antarctica through the use of sophisticated satellite tags and physical examinations.

Unlocking ice sheets' mysteries

A University at Buffalo-led research team reports that prehistoric glaciers reacted rapidly to a brief cold snap, providing a rare glimpse of glaciers' response to past climate change.
