Short-term hormone therapy plus radiation therapy increases survival for men with early-stage prostate cancer
Short-term hormone therapy (androgen deprivation therapy: ADT) given in combination with radiation therapy for men with early-stage prostate cancer increases their chance of living longer and not dying from the disease, compared with that of those who receive the same radiation therapy alone, according to a Radiation Therapy Oncology Group study published in the July 14 issue of the New England Journal of Medicine.

Cortisol controls recycling of bile acids
Cortisol is responsible for the recycling of bile acids from the blood, discovered scientists of the German Cancer Research Center. If this recycling is disrupted, the animals develop gallstones and lose weight because they are no longer able to digest dietary fats. They also use more energy for heat production. The researchers assume that regulation of recycling serves the purpose of conserving energy efficiently in times of need.

Response to alcohol, peers, expectancies, and coping all contribute to adolescent drinking
A low level of response (LR) to alcohol is one of several genetically influenced characteristics that may increase an individual's risk for heavy drinking and alcohol problems. A new study has examined the LR model of risk among adolescents in the United Kingdom. Findings indicate that a low LR is related to more adverse alcohol outcomes through partial mediation by peer substance use, positive expectancies of the effects of alcohol, and using alcohol to cope with stress.

Scientists at Lawrence Berkeley National Laboratory and their colleagues at the University of California and Nanjing University have discovered a new relation among electric and magnetic fields and differences in temperature, which can result in swirling vortices of electrons and holes in semiconductor devices and emit sideways magnetic fields. Understanding the unusual new effect may lead to more efficient thermoelectric devices, which convert heat into electricity or electricity into heat.

Penn study finds a genetic basis for muscle endurance in animal study
Researchers have identified a gene for endurance, or more precisely, its negative regulator. Not having the gene relates to greater endurance in the knockout mice that were studied. The investigators also showed that the gene is linked to Olympic-level athletes in endurance sports such as swimming compared to athletes in sprint sports such as the 100-meter dash. The work has implications for improving muscle performance in disease states including metabolic disorders, obesity, and aging.

Think healthy, eat healthy: Caltech scientists show link between attention and self-control
Choosing what to have for dinner, it turns out, is a complex neurological exercise. But, according to researchers from Caltech, it's one that can be influenced by a simple shifting of attention toward the healthy side of life. And that shift may provide strategies to help us all make healthier choices -- not just in terms of the foods we eat, but in other areas, like whether or not we pick up a cigarette.
