An international research team led by Tim Nilsen, Ph.D., a professor of medicine and biochemistry and the director of the School of Medicine's Center for RNA Molecular Biology, has discovered an unexpected mechanism governing alternative splicing, the process by which single genes produce different proteins in different situations.

They may never win an Oscar, but scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have developed techniques for creating accurate movies of biological and chemical molecules, a feat only theorized up until now.

Researchers at the University of Pennsylvania School of Medicine have provided, for the first time, a detailed look at the molecular pathways underlying sleep apnea, which affects more than twelve million Americans, according to the National Institutes of Health.

With unprecedented sensitivity, Carnegie Mellon University’s Mark Bier has characterized large viral particles and bulky von Willebrand factors using a novel mass spectrometer. These exciting results may lead to new biological discoveries and represent a step closer to rapid disease diagnosis using mass spectrometry.

The metamorphosis of biology into a science offering numerically precise descriptions of nature has taken a leap forward with a Princeton team's elucidation of a key step in the development of fruit fly embryos - discoveries that could change how scientists think not just about flies, but about life in general.

A basic scientist in the Department of Surgery at Jefferson Medical College and the Kimmel Cancer Center at Jefferson has shared a patent on what may someday be a ubiquitous tool in DNA analysis. The discovery could have a range of applications, from forensics to cloning to bioterrorism.

From heart disease to AIDS and cancer, Biochemist Frank H. Stephenson helps you understand how the tools of biotechnology are being used to combat our most common afflictions. This book is an approachable look at how the human genome project will eventually benefit humanity in ways we haven't yet contemplated.

With research backgrounds ranging from materials engineering to molecular biophysics, seventeen leading scientists issued a statement today announcing that, much as the discovery of DNA and creation of the transistor revolutionized science, there is a new scientific field on the brink of revolutionizing our approach to problems ranging from eco-safe energy to outbreaks of malaria.

Scientists have puzzled for years in understanding how plants pass signals of stress, due to lack of water or salinity, from chloroplast to nuclei. They know that chloroplasts -- the cellular organelles that give plants their green color - have at least three different signals that can indicate a plant is under stress.
