It's a gas: New discovery may lead to heartier, high-yielding plants
In a research report published in the November 2009 issue of the journal GENETICS, scientists show how a family of genes (1-aminocyclopropane-1-carboxylate synthase, or ACS genes) are responsible for production of ethylene. view more (2009-11-23)
New research into the mechanisms of gene regulation
A team led by Penn State's Ross Hardison, T. Ming Chu Professor of Biochemistry and Molecular Biology, has taken a large step toward unraveling how regulatory proteins control the production of gene products during development and growth. view more (2009-11-20)
Maize cell wall genes identified, giving boost to biofuel research
Purdue University scientists have helped identify and group the genes thought to be responsible for cell wall development in maize, an effort that expands their ability to discover ways to produce the biomass best suited for biofuels production. view more (2009-11-20)
Faulty body clock may make kids bipolar
Malfunctioning circadian clock genes may be responsible for bipolar disorder in children. Researchers writing in the open access journal BMC Psychiatry found four versions of the regulatory gene RORB that were associated with pediatric bipolar disorder. view more (2009-11-12)
Iowa State University researcher discovers key to vital DNA, protein interaction
A researcher at Iowa State University has discovered how a group of proteins from plant pathogenic bacteria interact with DNA in the plant cell, opening up the possibility for what the scientist calls a "cascade of advances." view more (2009-11-11)
Discovery in worms by Queen's researchers points to more targeted cancer treatment
Researchers at Queen's University have found a link between two genes involved in cancer formation in humans, by examining the genes in worms. The groundbreaking discovery provides a foundation for how tumor-forming genes interact, and may offer a drug target for cancer treatment. view more (2009-11-11)
Taking aim at mysterious DNA structures in the battle against cancer
Designers of anti-cancer drugs are aiming their arrows at mysterious chunks of the genetic material DNA that may play a key role in preventing the growth and spread of cancer cells, according to an article in the current issue of Chemical & Engineering News, ACS' weekly newsmagazine. view more (2009-11-05)
Drunken fruit flies help scientists find potential drug target for alcoholism
A group of drunken fruit flies have helped researchers from North Carolina State and Boston universities identify entire networks of genes-also present in humans-that play a key role in alcohol drinking behavior. view more (2009-11-04)
UM Scientists Create Fruit Fly Model to Help Unravel Genetics of Human Diabetes
As rates of obesity, diabetes, and related disorders have reached epidemic proportions in the US in recent years, scientists are working from many angles to pinpoint the causes and contributing factors involved in this public health crisis. view more (2009-11-03)
The skeleton: Size matters
Vertebrates have in common a skeleton made of segments, the vertebrae. During development of the embryo, each segment is added in a time dependent manner, from the head-end to the tail-end: the first segments to be added become the vertebrae of the neck, later segments become the vertebrae with ribs and the last ones the vertebra located in the... view more...

CSHL-led team discovers rare mutation dramatically increasing schizophrenia risk
An international team of researchers led by geneticist Jonathan Sebat, Ph.D., of Cold Spring Harbor Laboratory (CSHL), has identified a mutation on human chromosome 16 that substantially increases risk for schizophrenia. view more (2009-10-26)
Female choice benefits mothers more than offspring
The great diversity of male sexual traits, ranging from peacock's elaborate train to formidable genitalia of male seed beetles, is the result of female choice. view more (2009-10-23)
Alcohol Tolerance Switch Found in Fruit Flies
Researchers at North Carolina State University have found a genetic "switch" in fruit flies that plays an important role in making flies more tolerant to alcohol. view more (2009-10-22)
A master mechanism for regeneration?
Biologists long have marveled at the ability of some animals to re-grow lost body parts. Newts, for example, can lose a leg and grow a new one identical to the original. Zebrafish can re-grow fins. view more (2009-10-20)
TraDIS technique tackles typhoid
For the first time, researchers are able to look at the need for every gene in a bacterial cell in a single experiment. The new method will transform the study of gene activity and the search for weaknesses in bacterial armouries. view more (2009-10-16)
New cancer gene discovered
A new cancer gene has been discovered by a research group at the Sahlgrenska Academy. The gene causes an insidious form of glandular cancer usually in the head and neck and in women also in the breast. The discovery could lead to quicker and better diagnosis and more effective treatment. view more (2009-10-14)
Self-sacrifice among strangers has more to do with nurture than nature
Socially learned behavior and belief are much better candidates than genetics to explain the self-sacrificing behavior we see among strangers in societies, from soldiers to blood donors to those who contribute to food banks. view more (2009-10-13)
Researchers identify genes associated with onset age of Parkinson's disease
Researchers from Boston University School of Medicine (BUSM) have identified genes which may influence the onset age of Parkinson's Disease (PD). view more (2009-10-08)
Study finds 231 new genes associated with head and neck cancer
A Henry Ford Hospital study has identified 231 new genes associated with head and neck cancer, one of the most deadly cancers responsible for 2.1 percent of all cancer deaths in the United States. view more (2009-10-05)
