Gov't Creates Gene Database of Normal Human Tissues

...atabase as a crucial point of reference because it pinpoints which genes are expressed in many of the body's major organs under normal conditions, without known disease. Scientists can compare the genes from their own biological samples to this dictionary of normal expression. "Genes identified by the databas...

For first time, brain cells generated in a dish

...e body can on its own. In addition, the discovery pinpoints the cell that is truly what people refer to when they say "stem cell." Although the term is used frequently to describe immature cells that are the building blocks of bones, skin, flesh and organs, the actual stem cell as it exists in the brain has b...

A potential biological cause for sudden infant death syndrome

...ngs in a third population and, for the first time, pinpoints multiple defects in the serotonin system other than those in serotonin receptors: deficiencies in a particular type of serotonin receptor (called 5HT1A), an abnormally high number of serotonergic neurons (neurons that make and release serotonin), a p...

Scientists reveal structure of gateways to gene control

...iology and the study's lead investigator. The map pinpoints the locations of certain key gene-controlling nucleosomes -- spool-like structures that wrap short regions of DNA around a protein core. The research suggests how these nucleosomes, positioned at important transcription-promoter sites throughout the...

Do you hear what i see?

New research pinpoints specific areas in sound processing centers in the brains of macaque monkeys that shows enhanced activity when the animals watch a video. This study confirms a number of recent findings but contradicts classical thinking, in which hearing, taste, tou...

HIV and malaria combine to adversely affect pregnant women and their infants

...ished in PLoS Medicine (Public Library of Science) pinpoints how the virus targets the immune response in pregnant women. "PAM can be a deadly condition that leaves mothers and their children particularly vulnerable," says Professor Kevin Kain, an infectious disease specialist and lead author of the study. "We...
