Electric eel: most remarkable predator in animal kingdom

The electric eel may be one of the most remarkable predators in the entire animal kingdom.

That is the conclusion of Kenneth Catania, the Stevenson Professor of Biological Sciences at Vanderbilt University, who has spent the last three years studying the way this reclusive South American fish uses electric fields to navigate through the muddy waters of the Amazon and Orinoco basins where it lives, locate hidden prey and stun them into submission.

Professor Bordenstein on why the pronoun I is becoming obsolete

In PLOS Biology, Prof. Bordenstein and colleague Kevin Theis highlight that complex multicellular organisms are not and have never been autonomous individuals, but rather are biological units organized from numerous microbial symbionts and their genomes. Bordenstein and Theis  lay out ten principles that advance a unified theory of biology for hosts and their microbiomes.

Study reveals how protein helps cells tolerate DNA damage

Professor Brandt Eichman and graduate student Diana Chavez have discovered how the protein HLTF (helicase-like transcription factor) recognizes and remodels stalled replication “forks.” Their findings, reported in the June 18 issue of Molecular Cell, shed light on processes that help cells tolerate DNA and have implications for cancer therapies that target DNA replication and repair.

Locating the brain’s SAD center

Four to six percent of the American public suffer from seasonal affective disorder (SAD), a type of depression that occurs during the same season each year.

Biologists have known that variations in the amount of sunlight a person receives and her or his circadian clock play a role in the disorder. They have also proposed that the neurotransmitters serotonin and melatonin may be involved. However, they have not yet identified the underlying neurobiological mechanisms responsible.

Now, a team of Vanderbilt biologists has taken a major step toward this goal. In the May 7 issue of the journal Current Biology, they report that they have localized the seasonal light cycle effects that drive SAD to a small region in the mid-brain called the dorsal raphe nucleus in an experiment with mice, a common animal model for studying depression in humans.
