Science Study Profiles Over 600,000 Cells to Map Gene Activity Across Entire Adult Fish

Viewed from above, Danionella cerebrum offers a rare sight in a vertebrate: its brain, visible through the top of its head. Since the species was adopted for neuroscience research in 2018 and formally described in 2021, the tiny, transparent fish has drawn rapidly growing interest for its unique biology.

Newly Discovered Hair Cells on Squid May Offer Clues to Understand Hearing Loss in Humans

Scientists for years have known that squids have cells with bundles of tiny, hair-like protrusions on their heads and arms like those buried deep inside the human ear that allow us to hear.

High-Speed Microscope Captures Millisecond-Scale Brain Signaling Activity

Within the brain, neurons compute by generating electrical impulses. These signals travel throughout neurons, which are in turn connected in vast networks that control brain functions such as sensory perception, memory formation, and control of movement.

New Research Reveals Cellular Switches Driving Physical Adaptation in Marine Species

In the animal kingdom, only those who adapt to their environment will survive. This adaptation comes in a wide range of forms, from invisible internal shifts in gene expression to dramatic anatomical changes, such as tadpoles growing legs and transitioning to life on land as frogs.

Living Organisms Depend on Bacterial Production of Critical Vitamin B12

All living organisms need a little bit of it to form red blood cells and DNA, as well as to build and support brain and nerve cells. But it's hard to come by: Humans don't make it. Animals don't make it. Plants don't make it.
