Single microRNA fine-tunes innate immune response
A single microRNA, microRNA-223, in mice controls the production and activation of granulocytes, white blood cells essential for host defense against invading pathogens. view more (2008-02-20)
Master genetic switch found for chronic pain
In experiments with mice, researchers have found that eliminating what appears to be a master genetic switch for the development of pain-sensing neurons knocks out the animals' response to "neuropathic pain." view more (2006-01-26)
Technology identified could reduce the spread of rice virus
Building on plant virus research started more than 20 years ago, a biologist at Washington University in St. Louis and his colleague at the Donald Danforth Plant Science Center in St. Louis have discovered a technology that reduces infection by the virus that causes Rice Tungro Disease, a serious limiting factor for rice production in Asia. view more (2009-02-11)
Diabetes linked to male infertility; excess sugars in the body have direct effect on sperm quality
Diabetes in men has a direct effect on fertility, a scientist told the 24th annual conference of the European Society of Human Reproduction and Embryology today. view more (2008-07-09)
New Internet Music Phenomenon Paves The Way For Musical Web Search-engine
Embargoed until 00.01h, Thursday 17 October 2002 New research enables computers to name that tune A team of British and American scientists claim a world's first in online music recognition, paving the way for the musical equivalent of web search-engine Google; and the potential to resolve musical copyright disputes. Researchers at Queen Mary,... view more... (2002-10-14)
Newly discovered molecular switch helps decide cell type in early embryo development
Researchers have discovered a central molecular switch in fruit fly embryos that opens new avenues for studying the causes of birth defects and cancer in humans. Writing about their study in the Aug. 12 Developmental Cell, scientists at Cincinnati Children's Hospital Medical Center determined the switch to be a main tuning mechanism for... view more...

Targeting the dosage compensation complex
Three independent research papers in the April 1 issue of G&D detail the chromosome-wide binding of the Drosophila dosage compensation complex (DCC) to the single male X chromosome, shedding new light on the mechanism of DCC targeting. view more (2006-03-17)
Neural stem cell gene plays crucial role in eye development
Scientists at the University of North Carolina at Chapel Hill have demonstrated that normal development of the eye requires the right amount of a neural stem cell gene be expressed at the right time and place. view more (2006-05-16)
Salk scientists get to the root of plant cell fate
When Robert Burns compared his love to a red, red rose, he definitely wasn't referring to a topless mutant. That's because rather than being topped by a lovely, fragrant bloom, a rose mutant in the gene known as TOPLESS would be crowned by a homely second root. view more (2006-06-09)
Scientists solve structure of gene regulator that plays key role in cancer
Scientists at The Wistar Institute have collaborated on a major advance in understanding a gene regulator that contributes to some of the deadliest cancers in humans. The culmination of 10 years' work, their research paves the way for the development of new cancer therapies. view more (2008-02-14)
Adaptation to oxygen deprivation elucidates tumor physiology
Two new studies in the March Cell Metabolism reveal a survival mechanism by which cells adapt to oxygen starvation by ratcheting down their demand. view more (2006-03-08)
UCLA researchers reprogram normal tissue cells into embryonic stem cells
Researchers at the Institute for Stem Cell Biology and Medicine at UCLA were able to take normal tissue cells and reprogram them into cells with the same unlimited properties as embryonic stem cells, the cells that are able to give rise to every cell type found in the body. view more (2007-06-07)
Complexity constrains evolution of human brain genes
Despite the explosive growth in size and complexity of the human brain, the pace of evolutionary change among the thousands of genes expressed in brain tissue has actually slowed since the split, millions of years ago, between human and chimpanzee. view more (2006-12-26)
Dying of excitement
For neurons, overexcitement is deadly. To avoid this, brain cells must sop up unneeded neurotransmitters from the synapse through membrane-bound transporters. If these transporters fail, neurons and other brain cells get excited to death- a phenomenon that may contribute to brain damage during stroke and Alzheimer's disease. view more (2006-03-06)
Researchers discover new form of cancer gene regulation
The Quaking gene, first described as a mutation in mice that causes rapid tremor, is thought to suppress tumor formation and protect humans from cancer. view more (2005-11-08)
Lifestyle can alter gene activity, lead to insulin resistance
A Finnish study of identical twins has found that physical inactivity and acquired obesity can impair expression of the genes which help the cells produce energy. view more (2008-06-19)
Protein that controls hair growth also keeps stem cells slumbering
Like fine china and crystal, which tend to be used sparingly, stem cells divide infrequently. It was thought they did so to protect themselves from unnecessary wear and tear. view more (2008-01-25)

New Mount Sinai research tracks effects of addictive drugs on brain
Mount Sinai researchers may have unlocked the key to better understanding the effect addictive drugs have on the human brain. view more (2008-05-16)
Existing drugs show promise for treating end-stage renal disease in lupus
Studies in mice suggest that two drugs already approved by the U.S. Food and Drug Administration show promise for treating the complications of lupus. view more (2007-11-12)
