Scientists at the University of North Carolina at Chapel Hill have identified a gene crucial to the final step of the formation of a functional sperm cell.   view more (2007-10-18)

How schizophrenia develops: Major clues discovered
Schizophrenia may occur, in part, because of a problem in an intermittent on/off switch for a gene involved in making a key chemical messenger in the brain, scientists have found in a study of human brain tissue.   view more (2007-10-17)

Study identifies pathway required for normal reproductive development
Massachusetts General Hospital (MGH) clinical researchers, in collaboration with basic scientists from the University of California, Irvine (UC Irvine) have identified a new molecular pathway required for normal development of the reproductive, olfactory and circadian systems in both humans and... view more (2007-10-16)

Enhanced DNA-repair mechanism can cause breast cancer
Although defects in the "breast cancer gene," BRCA1, have been known for years to increase the risk for breast cancer, exactly how it can lead to tumor growth has remained a mystery.   view more (2007-10-15)

Researchers reveal repressor protein blocks neural stem cell development
A protein known to repress gene transcription at the molecular level in a variety of processes also blocks embryonic neural stem cells from differentiating into neurons.   view more (2007-10-11)

CU-Boulder worm study sheds light on human aging, inherited diseases
Microscopic worms used for scientific research are living longer despite cellular defects, a discovery that is shedding light on how the human body ages and how doctors could one day limit or reverse genetic mutations that cause inherited diseases.   view more (2007-10-02)

EURYI project to understand how the brain wires during embryogenesis
One of the great questions of neurobiology, how the brain is built up during embryonic development, could be resolved by a young French scientist in an award winning project organised by the European Science Foundation (ESF) and the European Heads of Research Councils (EuroHORCS).   view more (2007-09-24)

Cell-surface sugar defects may trigger nerve damage in multiple sclerosis patients
Defects on cell-surface sugars may promote the short-term inflammation and long-term neurodegeneration that occurs in the central nervous system of multiple sclerosis patients, according to University of California, Irvine researchers.   view more (2007-09-21)

Toward a faster prenatal test for Down syndrome
Scientists in California are reporting an advance toward rapid testing for pre-natal detection of Down syndrome and other birth defects that involve an abnormal number of chromosomes.   view more (2007-09-19)

Bats add their voice to the FOXP2 story
When it comes to the FOXP2 gene, humans have had most to shout about. Discoveries that mutations in this gene lead to speech defects and that the gene underwent changes around the time language evolved both implicate FOXP2 in the evolution of human language.   view more (2007-09-19)

Women prescribed drugs linked to birth defects not often advised to use birth control
Although prescription medications that may increase the risk of birth defects are commonly used by women in their childbearing years, only about half receive contraceptive counseling from their health care providers.   view more (2007-09-18)

A molecule that protects from neuronal disorders
Many neuronal disorders, including epilepsy, schizophrenia and lissencephaly - a form of mental retardation -, result from abnormal migration of nerve cells during the development of the brain.   view more (2007-09-17)

Zebrafish to shed light on human mitochondrial diseases
Zebrafish can now be used to study COX deficiencies in humans, a discovery that gives scientists an unprecedented window to view the earliest stages of mitochondrial impairments that lead to potentially fatal metabolic disorders.   view more (2007-09-14)

Mice provide important clues to obsessive-compulsive disorder
Mice born without a key brain protein compulsively groom their faces until they bleed and are afraid to venture out of the corner of their cages.   view more (2007-08-23)

Gene triggers obsessive compulsive disorder-like syndrome in mice
Using genetic engineering, researchers have created an obsessive-compulsive disorder (OCD) - like set of behaviors in mice and reversed them with antidepressants and genetic targeting of a key brain circuit.   view more (2007-08-23)

NYC-area 1st: Morgan Stanley Children's Hospital performs transcatheter pulmonary valve replacement
A breakthrough new procedure may improve quality of life for children and adults with a common type of congenital heart defect that interferes with the body's ability to oxygenate blood through the lungs.   view more (2007-08-23)

Water, air and soil pollution causes 40 percent of deaths worldwide, Cornell research survey finds
About 40 percent of deaths worldwide are caused by water, air and soil pollution, concludes a Cornell researcher. Such environmental degradation, coupled with the growth in world population, are major causes behind the rapid increase in human diseases, which the World Health Organization has... view more (2007-08-14)

Defects in critical gene lead to accelerated lung tumor growth
Cancer causing mutations occur in our bodies every day - but luckily, we have specific genes that recognize these malignant events and keep cells from growing out of control. Only a few of these genes - called tumor suppressors - are currently known.   view more (2007-08-06)

New data reveal pregnancies exposed to accutane despite risk management program
Despite a mandatory program designed to prevent pregnant women from being exposed to the anti-acne medication Accutane and similar medications containing isotretinoin (a known teratogen or birth defect-causing agent), 122 pregnancies were exposed during the first year of the program, known as... view more (2007-08-01)

Hopkins team develops first mouse model of schizophrenia
Johns Hopkins researchers have genetically engineered the first mouse that models both the anatomical and behavioral defects of schizophrenia, a complex and debilitating brain disorder that affects over 2 million Americans.   view more (2007-07-31)

Nottingham biosciences million pound injection
Nottingham's strength as a UK Science City is further underlined today, with news that the Wellcome Trust, the UK's largest medical research charity, has awarded almost £1 million to an innovative biosciences company.   view more (2007-07-30)

Hidden order found in a quantum spin liquid
An international team, including scientists from the London Center for Nanotechnology, has detected a hidden magnetic "quantum order" that extends over chains of 100 atoms in a ceramic without classical magnetism. The findings, which are published today, July 26, by Science, have... view more (2007-07-27)

Researchers at the University of Michigan Comprehensive Cancer Center have identified a gene linked to the development of an aggressive form of breast cancer.   view more (2007-07-27)

Discovery of 'hidden' quantum order improves prospects for quantum super computers
An international team of scientists, including several at The Johns Hopkins University, has detected a hidden magnetic "quantum order" that extends over chains of nearly 100 atoms in a material that is otherwise magnetically disordered.   view more (2007-07-27)

Study finds HIV protease inhibitor drugs may adversely affect the scaffolding of the cell nucleus
UCLA scientists, along with collaborators from Purdue University, have demonstrated that HIV protease inhibitors - crucial drugs for HIV treatment - block a cellular enzyme important for generating the structural scaffolding for the cell nucleus.   view more (2007-07-17)
