First genome-wide mapping of DNA modification in embryonic stem cells

Stem cell researchers at UCLA have generated the first genome-wide mapping of a DNA modification called 5-hydroxymethylcytosine (5hmC) in embryonic stem cells, and discovered that it is predominantly found in genes that are turned on, or active.

Neogen develops new pathogen DNA detection method for E. coli strains

Neogen Corporation has announced the development of a breakthrough pathogen detection and identification technology that provides next day, DNA-specific test results for seven pathogenic E. coli strains. The technology could be adapted to target almost any bacterium of concern in almost any food sample type.

Researchers discover novel combination of two mutations in a patient with ADHD

Often enough, in science as in life, unexpected knowledge has a personal impact. Researchers seeking rare gene variants in just a few individuals with attention-deficit hyperactivity disorder (ADHD) discovered that one patient had a novel combination of two mutations.

World's best genetic map now built in African-Americans

A group of researchers from the University of Oxford, Harvard Medical School and the University of Mississippi Medical Center has constructed the world's most detailed genetic map, a tool scientists can use to better understand the roots of disease and how DNA is passed generationally to create diversity in the human species.

Researchers develop mouse model of rare human birth defect

A team of researchers from the University of Utah and Brigham Young University has developed a mouse model of focal dermal hypoplasia, a rare human birth defect that causes serious skin abnormalities and other medical problems. This animal model not only provides insight into studying the cause of focal dermal hypoplasia (FDH), but also offers a novel way to study a signaling pathway that is crucial for embryonic development.

Receptor GPR56 could have a critical role in cancer progression

Melanoma is devastating on many fronts: rates are rising dramatically among young people, it is deadly if not caught early, and from a biological standpoint, the disease tends to adapt to even the most modern therapies, known as VEGF inhibitors.

Loss of critical male development gene causes male cells to become female

University of Minnesota Medical School and College of Biological Sciences researchers have made a key discovery showing that male sex must be maintained throughout life.

Computer modeling to predict how peripheral nerve axon responds to electrical stimuli

Researchers at Case Western Reserve University have developed a computer modeling method to accurately predict how a peripheral nerve axon responds to electrical stimuli, slashing the complex work from an inhibitory weeks-long process to just a few seconds.

Humans and zebrafish share mechanisms that regulate the circadian system

Circadian rhythms - the natural cycle that dictates our biological processes over a 24-hour day - does more than tell us when to sleep or wake. Disruptions in the cycle are also associated with depression, problems with weight control, jet lag and more. Now Prof. Yoav Gothilf of Tel Aviv University's Department of Neurobiology at the George S. Wise Faculty of Life Sciences is looking to the common zebrafish to learn more about how the human circadian system functions.

Babies of stressed pregnant mums may have lasting effects

According to a new study high levels of stress during pregnancy can cause an unborn child to have lifelong mental scars. Researchers have found that a mother facing unnecessary crises can leave an imprint in the brains of her children, making them less able to cope as they get older.

Male infertility cause found in defective gene

Researchers have found a new cause of infertility that could allow millions of infertile couples around the world to have a child. The team found a common gene mutation that causes sperm to be far less able to swim through the mucus of the cervix and reach the egg.

Diabetes gene linked to Alzheimer’s

Researchers from Mount Sinai School of Medicine have identified a gene that causes diabetes kills nerve cells in the brain, possibly resulting in Alzheimer’s disease.

Latest advances in Alzheimer's research presented at AAIC 2011

This week, more than 5,000 scientists from around the world gathered in Paris to report the latest advances in Alzheimer's research at the Alzheimer's Association International Conference 2011.

Scientists discover new dominant gene linked to Parkinson's

The newly discovered gene is known as VPS35, the sixth one which has been associated with Parkinson's disease and the third dominant gene.

LLS awards new SCOR grants valued at $12.5M for research in lymphoma and myeloproliferative neoplasms

The Leukemia & Lymphoma Society (LLS) today announced it has awarded two new Marshall A. Lichtman Specialized Center of Research (SCOR) grants to Frederick W. Alt, Ph.D., Harvard Medical School, and Anthony Green, M.D., Ph.D., University of Cambridge. Each SCOR is valued at $1.25 million a year for five years for a total of $6.25 million.

Global research initiatives to standardize Alzheimer's biomarkers

As the Alzheimer's field moves closer to new and earlier tests for the disease, innovative global research initiatives are taking the first important steps to standardize Alzheimer's biomarkers, as evidenced by two presentations made today at the Alzheimer's Association(R) International Conference 2011 (AAIC 2011) in Paris.

Experimental online tool launched to guide HIV treatment decisions without the need for resistance testing

A new free online service with the potential to help HIV treatment in countries with limited healthcare resources was launched today. The system accurately predicts how patients will respond to different combinations of drugs without the need for expensive tests to read the viral genetic code. Data presented today at the 6th IAS Conference on HIV Pathogenesis, Treatment and Prevention (IAS 2011) demonstrated the accuracy of the system for patients in Romania and South Africa whose treatment was failing (abstract MOPE146).

Researchers discover new gene mutation associated with Parkinson's

Researchers have discovered a new gene mutation they say causes Parkinson's disease. The mutation was identified in a large Swiss family with Parkinson's disease, using advanced DNA sequencing technology.
