Study is first to reveal hypogonadism as common complication of diabetes

Low testosterone production appears to be a common complication of type 2 diabetes in men, affecting 1 out of 3 diabetic patients, a new study has shown. Moreover, results of the investigation show that this condition, known clinically as hypogonadism, is caused not by a defect in the testes, where testosterone is produced, but by improper functioning of the pituitary gland, which controls production of tes

New research, headed by microbiologists from the University of Georgia, show for the first time that Salmonella – a widespread and often deadly bacterial pathogen – use molecular hydrogen to grow and become virulent. The discovery represents a way that diseases caused by Salmonella and other enteric infections could be lessened or even eliminated.

The research, just published in the journal Infection and Immunity, was led by Rob Maier, Georgia Research Alliance Eminent Scholar a

The American Chiropractic Association (ACA) is applauding a new study from the Medical Research Council (MRC) that shows that spinal manipulation – the primary form of care performed by doctors of chiropractic – combined with an exercise program offers effective treatment for those suffering from back pain. The study, published in the Nov. 19 issue of the British Medical Journal, found that a collective approach to back pain treatment provided “significant relief of symptoms and improvements in ge

Findings are disapointing, but some changes and more time could improve results

A new UCLA study released Nov. 26 reports higher arrest rates among drug offenders diverted to treatment during the first six months of California’s Substance Abuse and Crime Prevention Act (SACPA), commonly known as Proposition 36. The findings show SACPA clients were 48 percent more likely to be arrested for a drug offense within a year of admission than clients entering treatment through other c

Terrorist attacks like those on Sept. 11, large-scale industrial accidents like Three Mile Island, hurricanes like Andrew, or earthquakes like the one in Northridge, Calif., that killed 60 people–these are all what economists call low probability, high consequence events. Making economic decisions about how to prepare for such “extreme events” is a difficult process. Under what circumstances are the benefits of strengthening a building against explosions or earthquakes worth the costs? A new s

If you’ve ever been tempted to drop a friend who tended to freeload, then you have experienced a key to one of the biggest mysteries facing social scientists, suggests a study by UCLA anthropologists.

“If the help and support of a community significantly affects the well-being of its members, then the threat of withdrawing that support can keep people in line and maintain social order,” said Karthik Panchanathan, a UCLA graduate student whose study appears in Nature. “Our stud
