Do cash rewards for healthier habits work? Maybe, says a new study, if you add on one more condition -- peer pressure. A growing number of companies are offering employees an opportunity to boost earning power at work via cash incentives to stay healthy. Under the Affordable Care Act, employers will soon be able to offer even...

A multi-institution study has found that tying financial incentives to group weight loss led to significantly greater weight loss than cash awards based on an individual's success in losing weight on his or her own. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/m...

Risk prediction tools that estimate future risk of heart disease and stroke may be more useful predictors of future decline in cognitive abilities, or memory and thinking, than a dementia risk scores, according to a new study. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/m...

A randomized controlled trial finds that 12 weeks of physical plus mental activity in inactive older adults with cognitive complaints was associated with significant improvement in cognitive function but there was no difference between intervention and control groups. Fuente :...

Almost 4 million people die annually from household air pollution (HAP) caused by exposure to the combustion of biomass fuels, kerosene, or coal. A new article explains the need for studies into biomarkers of HAP exposure and predictors of respiratory disease. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/F...

Loop diuretics, more commonly known as water pills, are the most widely prescribed heart failure medications, but few studies had extensively compared their effectiveness until researchers examined three approved loop diuretics and found that even though one of them might offer more benefit, it is rarely prescribed.

Follow-up care after an emergency room visit for chest pain significantly reduced the risk of heart attack or death among high risk patients.  Chest pain is the most common reason patients go to the ER. However, one in four chest pain patients didn’t seek follow-up care within a month, as recommended. Fuente :...

Using the same strategy that a common virus employs to evade the human immune system, researchers have modified adult stem cells to increase their survival -- with the goal of giving the cells time to exert their natural healing abilities.

A research team has enhanced a device they developed to identify and "grab" circulating tumor cells, or CTCs, that break away from cancers and enter the blood, often leading to the spread of cancer to other parts of the body. If more studies confirm the technology's effectiveness, the NanoVelcro Chip device could enable...

An elusive step in the process of human DNA replication has been observed, for the first time, by scientists. The step, which is crucial for DNA replication in humans and other forms of life, had previously remained mysterious and had not been well studied in human DNA. Fuente :...

If you could peek at the inner workings of a computer processor you would see billions of transistors switching back and forth between two states. In optical communications, information from the switches can be encoded onto light, which then travels long distances through glass fiber. Researchers...
