How key enzyme repairs sun-damaged DNA

Researchers have long known that humans lack a key enzyme that reverses severe sun damage. For the first time, researchers have witnessed how this enzyme works at the atomic level to repair sun-damaged DNA. In the early online edition of the journal Nature, Ohio State University physicist and chemist Dongping Zhong and his colleagues describe [...]

Antibody may be effective against Influenza outbreaks

Researchers have discovered a monoclonal antibody that is effective against "Avian" H5N1, seasonal H1N1 and the 2009 "Swine" H1N1 influenza. A team of scientists from Sea Lane Biotechnologies, LLC, in collaboration with Mt. Sinai School of Medicine, St. Jude Research Hospital and the Scripps Research Institute, have shown that this antibody potently prevents and treats [...]

Heart Patients with Anxiety Disorder face more Heart Attacks and Deaths

Among patients with heart disease, anxiety disorders appear to be associated with a higher risk of stroke, heart attack, heart failure and death, according to a report in the July issue of Archives of General Psychiatry, one of the JAMA/Archives journals. As many as 24 percent to 31 percent of patients with heart disease also [...]

Mechanism that may trigger Degenerative Disease identified

A mechanism that regulates stem-cell differentiation in mice testes suggests a similar process that may trigger degenerative disease in humans, according to a Penn State College of Agricultural Sciences reproductive physiologist. Research involved manipulating a protein called STAT3 that signals stem cells to decide whether to differentiate into a specialized type of cell or self-renew [...]

Identification of protein that modulates metabolic dysfunction in obesity

(Boston) – Researchers from Boston University School of Medicine (BUSM) have discovered that Sfrp5, which refers to secreted frizzled-related protein 5, is an anti-inflammatory adipokine whose expression is disrupted in animal models of obesity and type 2 diabetes. The findings, which currently appear on-line in Science, may provide a new way of targeting metabolic disease, [...]

Cold Sore Virus linked to Schizophrenia

Exposure to the common cold sore virus may be partially responsible for shrinking regions of the brain and the loss of concentration skills, memory, coordinated movement and dexterity widely seen in patients with schizophrenia, according to research led by Johns Hopkins scientists. The research, described in the May Schizophrenia Research, could lead to new ways [...]

Response to Vaccines change with Gender

Biological differences between the sexes may significantly affect responses to vaccines, according to the researchers at the Johns Hopkins Bloomberg School of Public Health. The researchers examined published data from numerous adult and child vaccine trials and found that sex is a fundamental, but often overlooked predictor of vaccine response. The findings, published in the [...]

ADHD linked to interaction of Genetics and Psychology

Attention-Deficit Hyperactivity Disorder (ADHD) may be caused by alterations in the serotonin neurotransmission system combined with a tendency to experience psychosocial distress. Researchers writing in BioMed Central’s open access journal Behavioral and Brain Functions found that ADHD behaviors in children and adolescents were associated with interactions between low and high serotonin activity and self-blame in [...]

Discovery of 9 new planets challenges the theory of Planet Formation

A team of astronomers have discovered 9 new planets outside our solar system! The nine planets are called "Hot Jupiters." Unlike the planets in our solar system, two of the newly discovered planets are orbiting in the opposite direction to the rotation of their host star. This, along with a recent study of other exoplanets, [...]

Discovery of World’s Deepest Undersea Volcanic Vents

A British scientific expedition has discovered the world’s deepest undersea volcanic vents, known as ‘black smokers’, 3.1 miles (5000 metres) deep in the Cayman Trough in the Caribbean. Using a deep-diving vehicle remotely controlled from the Royal Research Ship James Cook, the scientists found slender spires made of copper and iron ores on the seafloor, [...]
