Inspired by the aquatic wriggling of beetle larvae, a research team has designed a propulsion system that strips away paddles, sails, and motors and harnesses the energy within the water’s surface. The technique destabilizes the surface tension surrounding the object with an electric pulse and causes the craft to move via the surface’s natural pull.
New research on genetic basis of psoriasis may prove important for early diagnosis and prediction of an individual’s risk for this common chronic skin disease.

Researchers in Spain have found that football has changed so little during recent World Cups that, if shown action from matches, we would be incapable today of differentiating between a France ’98 game and another from Germany ’06.

Although primary prostate surgery or radiotherapy is successful in many cases of prostate cancer, some patients suffer a recurrence of the disease, which is most often first detected by a measurable PSA blood test — affecting 30 percent to 40 percent of patients after surgery. The presence of cancer potentially outside the prostate after surgery, [...]
The first study documenting methicillin-resistant Staphylococcus aureus (MRSA) in swine and swine workers in the United States has just been published. The investigators found a strain of MRSA known as ST398 in a swine production system in the Midwest.

In the year following Hurricane Katrina, the health of survivors 65 and over declined nearly four times that of a national sample of older adults not affected by the disaster, according to a new study.

Unchecked global warming would leave ocean dwellers gasping for breath. Dead zones are low-oxygen areas in the ocean where higher life forms such as fish, crabs and clams are not able to live. Scientists have now shown that unchecked global warming would lead to a dramatic expansion of low-oxygen areas zones in the global ocean [...]
Americans who use illegal diet pills from South America may be taking amphetamines without knowing it and seriously risking both their health and their jobs. Physicians need to be made aware of the range of serious side effects of these drugs to allow them to identify and treat those patients presenting with unexplained symptoms.

The rate of sudden deaths increased six-fold in the first year that California law enforcement agencies deployed the use of stun guns, according to a new study. Findings also showed a two-fold increase in the rate of firearm-related deaths during the same time period.
Scientists have shown that HIV faces a genetic “bottleneck” when the virus is transmitted heterosexually from one person to another, by way of the genital mucosa. The results explain why prior infection by other sexually-transmitted diseases (STDs) makes individuals more susceptible to HIV infection.
