Developmental delay could stem from nicotinic receptor deletion
The loss of a gene through deletion of genetic material on chromosome 15 is associated with significant abnormalities in learning and behavior, said a consortium of researchers led by Baylor College of Medicine (www.bcm.edu) in a report that appears online today in the journal Nature Genetics. view more (2009-11-09)
Breeding better broccoli
Carotenoids-fat-soluble plant compounds found in some vegetables-are essential to the human diet and reportedly offer important health benefits to consumers. 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)
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)
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)
New research provides new insight into age-related muscle decline
If you think the air outside is polluted, a new research report in the September 2009 issue of the journal Genetics might make you to think twice about the air inside our bodies too. view more (2009-09-23)
Racial Disparities in Diabetes Prevalence Linked to Living Conditions
The higher incidence of diabetes among African Americans when compared to whites may have more to do with living conditions than genetics, according to a study led by researchers at the Johns Hopkins Bloomberg School of Public Health. view more (2009-09-22)
Explaining why pruning encourages plants to thrive
Scientists have shown that the main shoot dominates a plant's growth principally because it was there first, rather than due to its position at the top of the plant. view more (2009-09-22)
Dartmouth researchers get personal with genetics
Two recent studies by Dartmouth researchers use individual genetic data to reveal the powers and limits of our current understanding of how the genome influences human health and what genes can reveal about the ancestry of the people of New Hampshire. view more (2009-09-16)
Sex talk revelations of the lonely Y chromosome
In the week that the University of Leicester celebrates the 25th anniversary of the discovery of DNA fingerprinting new findings from the world-renowned University of Leicester Department of Genetics reveal for the first time that the male and female do truly communicate -at least at the fundamental genetic level. view more (2009-09-11)
Michigan Tech Mathematicians Identify Genes Linked to Lou Gehrig's Disease
Michigan Technological University researchers have linked three genes to the most common type of amyotrophic lateral sclerosis (ALS), generally known as Lou Gehrig's disease. view more (2009-09-10)
Gene variation is 'major genetic determinant of psoriasis'
A specific genetic region that has been increasingly identified as the strongest genetic link to psoriasis has an even more significant role in the chronic skin disease than has been suspected, University of Utah medical researchers show in a new study. view more (2009-08-28)
Not only the gene itself, its abnormal regulation can also trigger short stature
A specific gene is particularly frequently involved in the development of short stature. Researchers in Heidelberg have now discovered that sequences of genetic material on the X and Y chromosome that regulate this gene are also crucial for growth in children. view more (2009-08-26)
Faster, cheaper way to find disease genes in human genome passes initial test
University of Washington (UW) researchers have successfully developed a novel genome-analysis strategy for more rapid, lower cost discovery of possible gene-disease links. view more (2009-08-18)
Technique enables efficient gene splicing in human embryonic stem cells
A novel technique allows researchers to efficiently and precisely modify or introduce genes into the genomes of human embryonic stem cells (ESCs) and induced pluripotent stem (iPS) cells, according to Whitehead scientists. view more (2009-08-14)
Genetic risk, not anesthesia exposure, impacts cognitive performance
A recent study of more than 2,000 identical twins found that medical problems early in life, rather than the neurotoxic effects of anesthesia, are likely linked to an individual's risk for developing learning disabilities. view more (2009-08-05)
Researchers Identify New Method to Selectively Kill Metastatic Melanoma Cells
An international team of researchers has identified a new method for selectively killing metastatic melanoma cells, which may lead to new areas for drug development in melanoma - a cancer that is highly resistant to current treatment strategies. view more (2009-08-04)
A genetic basis for schizophrenia
Schizophrenia is a severely debilitating psychiatric disease that is thought to have its roots in the development of the nervous system; however, major breakthroughs linking its genetics to diagnosis, prognosis and treatment are still unrealized. view more (2009-07-22)
Surprising new insights into the repair strategies of DNA
A microscopic single-celled organism, adapted to survive in some of the harshest environments on earth, could help scientists gain a better understanding of how cancer cells behave. view more (2009-07-16)
DNA variations linked to brain tumors
Mayo Clinic researchers and colleagues at the University of California San Francisco (UCSF) have found a connection between DNA alterations on human chromosome 9 and aggressive brain cancer known as glioblastoma. view more (2009-07-06)
