Researchers say type of helmet not associated with lower risk of concussion

40,000 high school football kids get a concussion every year, but contrary to equipment manufacturers' claims, the specific brand of helmet and helmet age were not associated with lower risk of concussion, say researchers presenting their work today at the American Orthopaedic Society for Sports Medicine's Annual Meeting in Chicago, IL.

Scientists discover new details of biochemical interactions necessary for cell division

Building on earlier work exploring the complex choreography by which intricate cellular proteins interact with and copy DNA prior to cell division, scientists at the U.S. Department of Energy's Brookhaven National Laboratory and collaborators have captured a key step-molecular images showing how the enzyme that unwinds the DNA double helix gets drawn to and wrapped around its target.

Infrared light allows characterization of pathogens

The bacterium Staphylococcus aureus (S. aureus) is commonly found in nature and frequently colonizes the skin and the upper respiratory tract of humans. A healthy immune system can fight the microorganism but once the immune system is weakened the pathogen can spread and lead to life-threatening diseases of the lungs, the heart and other organs.

High folate intake during pregnancy may have undiscovered later-life effect in progeny

During pregnancy, women are normally advised to take high amounts of multivitamin supplements. In particular, folate is recommended to reduce the risk of neural tube defects in newborns. The problem is that, although vitamins are critical in fetal development, high vitamin doses during pregnancy may cause undesired effects on the offspring later in life.

Scientists successfully transplant insulin-producing cells from one species to another

In the first step toward animal-to-human transplants of insulin-producing cells for people with type 1 diabetes, Northwestern Medicine- scientists have successfully transplanted islets, the cells that produce insulin, from one species to another. And the islets survived without immunosuppressive drugs.

Scientists discover novel method to kill cancer cells

A University of Southampton Professor, in collaboration with colleagues at the BC Cancer Agency Research Centre, have discovered a novel way of killing cancer cells. The research, recently published in the journal Cell, has found a new potential treatment for cancer, which leaves the body's healthy cells undamaged, unlike traditional therapies such as radiotherapy

Research shows throwing mechanics of baseball pitcher can increase risk for elbow injuries

Certain elements of a pitcher's throwing mechanics can increase the risk for elbow injuries, according to information presented by researchers at the American Orthopaedic Society for Sports Medicine's Annual Meeting today in Chicago, IL.

New discovery reveals how RNA moves genetic information from DNA to create proteins

The discovery cracks the "RNA control code," which dictates how RNA - a family of molecules that mediates DNA expression - moves genetic information from DNA to create proteins.

Researchers discover potential markers for severity of juvenile idiopathic arthritis

Children who suffer from arthritis could one day receive more targeted treatment thanks to potential markers for the severity of the disorder discovered by researchers at the University of Adelaide and Women's and Children's Hospital.

Patients with early AD also have undiagnosed pre-diabetes, says Georgetown neurologist

When Georgetown University neurologist R. Scott Turner, MD, PhD, began enrolling people with mild to moderate Alzheimer's disease into a nationwide study last year, he expected to find only a handful of participants with undiagnosed glucose intolerance, as all the patients were already under a doctor's care and those with known diabetes were excluded.

New theory challenges orthodox view that cancer develops in each host by mutational accidents

A new way to look at cancer -- by tracing its deep evolutionary roots to the dawn of multicellularity more than a billion years ago -- has been proposed by Paul Davies of Arizona State University's Beyond Center for Fundamental Concepts in Science in collaboration with Charles Lineweaver of the Australian National University.

Genetic abnormality linked to cancer four times more common in people with type 2 diabetes

A type of genetic abnormality linked to cancer is more common in people with type 2 diabetes than the rest of the population, a new study has found.

Researchers identify important component for regulating stem cell niches

Proper tissue function and regeneration is supported by stem cells, which reside in so-called niches. New work from Carnegie's Yixian Zheng and Haiyang Chen identifies an important component for regulating stem cell niches, with impacts on tissue building and function. The results could have implications for disease research. It is published by Cell Stem Cell.

NeuRA study demonstrate that FTD patients lose emotional content/colour of memories

A study by researchers at Neuroscience Research Australia is the first to demonstrate that patients with frontotemporal dementia lose the emotional content/colour of their memories. These findings explain why FTD patients may not vividly remember an emotionally charged event like a wedding or funeral.

UC Riverside study finds that married men are less likely to die of HIV/AIDS

At the height of the AIDS epidemic in the 1980s men who were married were significantly less likely to die of HIV/AIDS than their divorced or otherwise single counterparts, according to a University of California, Riverside analysis of new mortality data for that era.
