Psychiatric researchers at The Zucker Hillside Hospital campus of The Feinstein Institute for Medical Research have uncovered evidence of a new gene that appears to increase the risk of developing schizophrenia, a disorder characterized by distorted thinking, hallucinations and a reduced ability to feel normal emotions..

Working in conjunction with researchers at the Harvard Medical School Partners Center for Genetics and Genomics in Boston, MA, the Zucker Hillside team utilized a cutting-edge technology called whole genome association (WGA) to search the entire human genome in 178 patients with schizophrenia and 144 healthy individuals.

Imagine the power of knowing the three-dimensional structures of all proteins. The 3D-structure can provide information about critical protein-protein interactions both from a global perspective as well as all the way down to the level of minuscule molecular and biochemical detail. In much the same way, structural information can reveal a lot about the protein’s evolutionary relationships and functions.

If you own a birdbath, chances are you’re hosting one of evolutionary biology’s most puzzling enigmas: bdelloid rotifers. These microscopic invertebrates—widely distributed in mosses, creeks, ponds, and other freshwater repositories—abandoned sex perhaps 100 million years ago, yet have apparently diverged into nearly 400 species. Bdelloids have remained an enduring enigma in part because biologists are still debating whether the species actually exist as true evolutionary entities. And if they do, what forces determine how they diverge? In the traditional view of species diversification, interbreeding promotes cohesion within a population—maintaining the species—and barriers to interbreeding (called reproduction isolation) promote species divergence.

In its early and most critical stages, human reproduction requires precise, vital functions. The role of one sperm-delivered protein, which is crucial to the process, is being closely observed by scientists from the United States and Canada.

In 2002, when astronomers first detected cosmic gamma rays – the most energetic form of light known – coming from the constellation Cygnus they were surprised and perplexed. The region lacked the extreme electromagnetic fields that they thought were required to produce such energetic rays. But now a team of theoretical physicists propose a mechanism that can explain this mystery and may also help account for another type of cosmic ray, the high-energy nuclei that rain down on Earth in the billions.

A newly discovered small molecule called IQ-1 plays a key role in preventing embryonic stem cells from differentiating into one or more specific cell types, allowing them to instead continue growing and dividing indefinitely, according to research performed by a team of scientists who have recently joined the stem-cell research efforts at the Keck School of Medicine of the University of Southern California.
