Moderate alcohol intake of at least 5 units every week is linked to poorer sperm quality in otherwise healthy young men, suggests research. And the higher the weekly tally of units, the worse the sperm quality seems to be, the findings indicate, prompting the researchers to suggest that young men should be advised to steer clear of habitual drinking.

Strong working memory puts brakes on problematic drug use

Posted: 02 Oct 2014 09:37 AM PDT

Scientists come one step closer to understanding why joint infections are difficult to treat. Biofilms play a role. "Biofilm formation has been suspected to play a key role during septic arthritis and prosthetic joint infection." said one expert. "This study could help explain why these infections have been so difficult to treat and point to therapeutic approaches that could make antibiotics more effective."

Could there be an end in sight for AIDS?

South Africa is the epicentre of the HIV and AIDS epidemic with a staggering 6.4 million HIV infected citizens. In 1990 the WHO reported just 386 cases in South Africa. Over the next 15 years, despite warnings from scientists and policy makers, a tidal wave of infections ensued.  How can policy and health provision cope to improve the outlook?  A new article strategically examines the whole epidemic and identifies economic, epidemiological, and programmatic points for transition and future improvement.

Diet affects mix of intestinal bacteria, risk of inflammatory bone disease

Posted: 02 Oct 2014 09:32 AM PDT

Diet-induced changes in the gut's bacterial ecosystem can alter susceptibility to an autoinflammatory bone disease by modifying the immune response, scientists have reported. The research provides insight into how the thousands of bacteria and other microorganisms that live in the intestines affect health.
