DNA evidence is in, newly discovered species of fish dubbed H. psychedelica

"Psychedelica" seems the perfect name for a species of fish that is a wild swirl of tan and peach zebra stripes and behaves in ways contrary to its brethren. So says University of Washington's Ted Pietsch, who is the first to describe the new species in the scientific literature and thus the one ...

UC Davis research shows that newly discovered drug reduces heart enlargement

DAVIS--Researchers at the University of California, Davis have discovered that a prototype drug reduces heart enlargement, one of the most common causes of heart failure. Heart failure, which occurs when the heart can't pump enough blood throughout the body, affects 5 million people in the Un...

Obesity starts in the head? 6 newly discovered genes for obesity have a neural effect

Leatherback turtles' newly discovered migration route may be roadmap to salvation

With a name like "Leatherback Turtle" you might think the sea turtles could stand up to just about anything the ocean can throw at them, and for more than a hundred million years, they have. But tough, long-lived critters though they are, the population of leatherbacks in the eastern Pacific Ocean...

Death, division or cancer? Newly discovered checkpoint process holds the line in cell division

Each day, a staggering number of cells perform a feat that still amazes researchers with its complexity: they divide to produce perfect replicas of each other. The process is called mitosis, and an inability to control it is one of the hallmarks of cancer. Little is known about the biochemica...

Study shows enzyme builds neurotransmitters via newly discovered pathway

The study, which was directed by Scripps Research Professor Benjamin Cravatt, Ph.D., is being published in the September 8 issue of The Journal of Biological Chemistry.
