FSU research uncovers new pathways for diabetes research

A new Florida State University study is changing how researchers look at diabetes research and the drugs used to treat the disease. In the Proceedings of the National Academy of Sciences, Associate Professor of Chemistry Brian Miller and post-doctoral researcher Carl Whittington report that a key enzyme involved in the body’s response to glucose can [...]

One simple molecule regulates sexual behavior in Drosophila

The common vinegar fly Drosophila melanogaster is a very well-studied animal. For decades, the fly has been used as a model organism in genetic research; its genome was fully sequenced in 2000. However, until now researchers have failed to identify the specific pheromone in this species that leads to mating success. Although the pheromones that [...]

UCI study sheds new light on low-light vision, could aid people with retinal deficits

Brain handles day- and nighttime optical signals the same, reacts quickly to loss of input Driving down a dimly lit road at midnight can tax even those with 20/20 vision, but according to a recent UC Irvine study, the brain processes the experience no differently than if it were noon. The same study also reveals [...]

Deconstructing brain systems involved in memory and spatial skills

In work that reconciles two competing views of brain structures involved in memory and spatial perception, researchers at University of California, San Diego School of Medicine have conducted experiments that suggest the hippocampus – a small region in the brain’s limbic system – is dedicated largely to memory formation and not to spatial skills, such [...]

New drug stalls estrogen receptor-positive cancer cell growth and shrinks tumors

An experimental drug rapidly shrinks most tumors in a mouse model of human breast cancer, researchers report in the Proceedings of the National Academy of Sciences. When mice were treated with the experimental drug, BHPI, “the tumors immediately stopped growing and began shrinking rapidly,” said University of Illinois biochemistry professor and senior author David Shapiro.
