Genetic Switches Behind Human Brain Evolution

The human brain differs from that of mice and monkeys because of its large cerebral cortex. The organ's most highly developed part, the cerebral cortex is responsible for thinking, perceiving and sophisticated communication. Scientists are just beginning to understand the molecular and cellular mechanisms that drive the growth of the

New Structure of Key Protein Holds Clues for Better Drug Design

odies. In addition to Wthrich and Eddy, authors of the study, "Allosteric Coupling of Drug Binding and Intracellular Signaling in the A2a Adenosine Receptor," were Tatiana Didenko and Pawel Stanczak of The Scripps Research Institute; Reto Horst of The Scripps Research Institute and Pfizer Worldwide Research and Development; Zhan-Guo Gao and

New Method Maps Chemicals in the Skin

More and more chemicals are being released into our environment. For example, parabens and phthalates are under discussion as two types of chemicals that can affect us. But so far it has not been possible to find out how they are absorbed by the skin. A new study from Chalmers

Kill Switches for Engineered Microbes Gone Rogue

Past efforts at Harvard's Wyss Institute for Biologically Inspired Engineering led by Core Faculty members Pamela Silver and James Collins have created "kill switches" in bacteria that cause them to commit suicide in laboratory conditions when they are not wanted anymore. "We needed to take our previous work further and

In the Fight Against Viral Infection, Spelling Counts

Now, scientists have found that a key similarity between our genes and those of many viruses -- a way of spelling out the genetic code -- has likely allowed viruses to evade our cellular defenses. Paul Bieniasz, a Rockefeller professor and Howard Hughes Medical Institute Investigator who led the work,

First Draft cell Atlas of the Small Intestine

This census, published in Nature, comprises a first-draft atlas of the small intestine's cellular composition, providing a reference for studying the biology of a host of conditions affecting or involving the gut, such as inflammatory bowel disease, cancers of the small intestine, celiac disease, and food allergies. The study also enhances
