Landmark study links 13 new genes to heart disease
Insight into the complex biological mechanisms that cause heart disease has taken a major step forward with the discovery of 13 new genes that increase the risk of coronary artery disease (CAD).

Zalutumumab significantly prolongs progression-free survival in patients with incurable head and neck cancer
Patients with incurable squamous-cell carcinoma of the head and neck whose chemotherapy is no longer working, who are given zalutumumab, survive significantly longer without the disease progressing than patients receiving best supportive care.

New role for an old molecule: protecting the brain from epileptic seizures
The aftermath of an epileptic seizure has some mysterious characters, including the molecule putrescine.

Elderly see pedestrians half as often as younger drivers, according to Ben-Gurion U. researchers
BGU researchers used two evaluation methods: driving in a traffic simulator while watching video of traffic scenes, and identifying hazardous situations.The video observation method showed that elderly drivers took longer to respond to pedestrian hazards.

Japanese scientists use alcoholic drinks to induce superconductivity
Japanese researchers have been immersing iron-based compounds in hot alcoholic beverages such as red wine, sake and shochu to induce superconductivity.

Newly identified cell population key to immune response
Scientists from the Walter and Eliza Hall Institute have identified the key immune cell population responsible for regulating the body's immune response.

Avoid risking children's health during home energy retrofits, renovations, experts urge
Home energy retrofits and renovations help fight climate change and can create healthier homes but greater training and caution during the process are needed to avoid the release of asbestos, volatile organic compounds, IQ-lowering lead dust and other toxic substances, according to a new report by the Canadian Environmental Law Association.

New report helps inform decisions about how science should be funded
A new study by researchers in the United Kingdom expands understanding of the different benefits provided to society by both clinical research and basic research.

New instrument keeps an 'eye' on nanoparticles
A UC Santa Barbara research team has developed a new instrument capable of detecting individual nanoparticles with diameters as small as a few tens of nanometers.

Gene responsible for severe osteoporosis disorder discovered
Scientists have identified a single mutated gene that causes Hajdu-Cheney syndrome, a disorder of the bones causing progressive bone loss and osteoporosis.

Institute for Health Metrics and Evaluation to launch new Global Health Data Exchange
The Institute for Health Metrics and Evaluation at the University of Washington has created a user-friendly, searchable data catalog for global health, public health, and demographic data.

International collaborative identifies 13 new heart-disease-associated gene sites
An international research collaboration has identified 13 new gene sites associated with the risk of coronary artery disease and validated 10 sites found in previous studies.

Rehabilitation within a day of knee replacement pays off
Starting rehabilitation sooner following knee arthroplasty surgery could pay dividends -- for both patients and hospitals.

Scientists probe the role of motor protein in hearing loss
From grinding heavy metal to soothing ocean waves, the sounds we hear are all perceptible thanks to the vibrations felt by tiny molecular motors in the hair cells of the inner ear.

The connection between a cell's cytoskeleton and its surface receptors
New findings from researchers at Harvard Medical School in Boston and the Hospital for Sick Children in Toronto may shed light on the mechanisms that regulate the organization of receptors on the cell surface, a critical aspect of cell signaling not well understood at this time.

New gene regions identified that predispose people to heart attacks, Stanford scientists say
Thirteen new gene regions have been convincingly linked to coronary atherosclerosis in a massive, new, international genetics study involving investigators from the Stanford University School of Medicine.

Cardiac catheter that can do it all
In an improvement over open-heart surgery, cardiologists now use catheters to eliminate damaged heart tissue in certain patients.
