Discovery of mechanism that protects somatic cells against the behaviour of germ cells

An IRB Barcelona research team discovers the mechanism that favors the correct separation of germ cells -- future ovules and sperm -- from the rest of the cells during embryonic development

Discovery of unique 'DNA signature' in human sperm - unlocks egg's fertility

Drs David Miller and David Iles from the University of Leeds, in collaboration with Dr Martin Brinkworth at the University of Bradford, have found that sperm writes a DNA signature that can only be recognised by an egg from the same species. This enables fertilisation and may even explain how a species develops its own unique genetic identity.

New microchip technology may accelerate drug discovery for cancer, other diseases

Flasks, beakers and hot plates may soon be a thing of the past in chemistry labs. Instead of handling a few experiments on a bench top, scientists may simply pop a microchip into a computer and instantly run thousands of chemical reactions, with results - literally shrinking the lab down to the size of a thumbnail.

Discovery of novel tumor suppressor

La Jolla Institute for Allergy & Immunology researchers studying an enzyme believed to play a role in allergy onset, instead have discovered its previously unknown role as a tumor suppressor that may be important in myeloproliferative diseases and some types of lymphoma and leukemia. Myeloproliferative diseases are a group of disorders characterized by an overproduction of blood cells by the bone marrow and include chronic myeloid leukemia. Lymphoma and leukemia are cancers of the blood.

Selective method kills 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.

Tiny device to 'sniff out' disease, heart attacks, poison and environmental pollution

Like the sensitive seismographs that can pick up tremors of impending earthquakes long before they strike, a similar invention from Tel Aviv University researchers may change the face of molecular biology.

Number of uninsured California kids may double

A new deal to balance California's budget may have serious repercussions for the health of the state's children, while South Carolina grapples with health cuts of its own. Meanwhile, New Jersey may become one of the first states to publically disclose hospital errors.

Heavy consumption of beer and spirits to 6 different cancers

Heavy drinkers of beer and spirits face a much higher risk of developing cancer than the population at large, says a group of Montreal epidemiologists and cancer researchers. Their findings show that people in the highest consumption category increased their risk of developing oesophageal cancer sevenfold, colon cancer by 80% and even lung cancer by 50%.

Neck surgery for cervical spine disorders alleviates headaches

A new study published in the August 2009 issue of the Journal of Bone and Joint Surgery (JBJS) finds that two years after anterior cervical neck operations, patients who have arthroplasty (disc replacement) or arthodesis (spine fusion) can be expected to have significant improvement in their headache symptoms.

Neural correlates of impaired cognitive-behavioral flexibility in anorexia nervosa

Anorexic patients drastically reduce food intake and are often not capable of changing their behavior. This can lead to life-threatening weight loss. Using MRI technology, scientists at Heidelberg University Hospital have discovered for the first time processes in brain metabolism that explain this disturbed eating behavior.

Opportunities and risks posed by synthetic biology

The new research field of synthetic biology will, in the medium term, open up a great deal of potential for combining novel genetic methods with engineering principles. This will facilitate the development, not only of new vaccines and medicines, but also of fuels and new materials.

Metformin associated with reduced risk of pancreatic cancer in diabetics

The antidiabetic medication metformin is associated with a reduced risk of pancreatic cancer in diabetics, according to a new study in Gastroenterology, the official journal of the American Gastroenterological Association (AGA) Institute. However, other commonly used therapies, such as insulin or insulin secretagogues, may be associated with increased risk for the deadly disease.

Sleep heart health study

A study in the Aug. 1 issue of the journal Sleep indicates that self-reported worsening in initiating and maintaining sleep over a five-year period was significantly associated with poorer mental quality of life, and increasing daytime sleepiness symptoms were associated with both poorer physical and mental quality of life.

Success of GERD therapy hinges on medication type and physician bedside manner

Patient satisfaction with their medications and the quality of interactions with their doctor reflect the success of gastroesophageal reflux disease (GERD) therapy, according to a new study in Clinical Gastroenterology and Hepatology, the official journal of the American Gastroenterological Association (AGA) Institute.

Seven out of ten U.S. children low in vitamin D

Seven out of ten U.S. children have low levels of vitamin D, raising their risk of bone and heart disease, according to a study by researchers at Albert Einstein College of Medicine of Yeshiva University. The striking findings suggest that vitamin D deficiency could place millions of children at risk for high blood pressure and other risk factors for heart disease.
