A new study shows how our bodies try to minimize potential 'collateral damage' caused by our immune system when fighting infection. The research may also provide new clues to why cigarette smoke is a significant risk factor for developing diseases of the lung such as chronic bronchitis and emphysema.

A study carried out by cardiologists has investigated the risk of myocardial infarction (heart attack) amongst winter sports tourists to the Tyrolean Alps. The research shows that inadequate preparation for the intense physical exertion required, combined with the effects of altitude and low temperature, leads to an increase in heart attack incidents, particularly during the first two days of vacation.

Scientists have demonstrated the synthesis of nanosize biological particles with the potential to fight cancer and other illnesses. The research introduces new approaches that are considered "green" nanobiotechnology because they use no artificial compounds.

Girls eating a high-fat diet during puberty, even those who do not become overweight or obese, may be at a greater risk of developing breast cancer later in life, according to researchers. The implications -- that a high-fat diet may have detrimental effects independent of its effect to cause obesity -- could drive new cancer prevention efforts.

Researchers are exploring a "fusion strategy" for making improved vaccines to protect pigs and humans against some strains of E. coli.

Women at increased risk of breast and ovarian cancer because of inherited mutations of the BRCA1 or BRCA2 genes who had prophylactic mastectomy or salpingo-oophorectomy (removal of the fallopian tubes and ovaries) had an associated decreased risk of breast cancer and ovarian cancer, according to a new study.

The malaria mosquito needs more than one family of odor sensors to sniff out its human prey, new research suggests. New research provides striking new evidence that Anopheles gambiae -- the species of mosquito that spreads malaria that infects some 250 million and kills 900,000 people annually -- has a second set of olfactory sensors that are fundamentally different from the set of sensors that scientists have known about and have been studying for the last 10 years.

A new study looks at how female versus male rats fared after suffering a trauma and subsequent hemorrhagic shock who were given Estradiol (estrogen). In the study, the Estradiol prevented vascular permeability following hemorrhagic shock.

The DASH diet reduced the estimated risk of having a heart attack in the next ten years by 18 percent when compared to a typical American eating plan, according to a new study. Both whites and African-Americans benefited from the diet, but African-Americans had the greatest benefit. Researchers provided all the food to the participants in this eight-week study.

Adding a variety of vegetables to one's diet may help decrease the chance of getting lung cancer, and adding a variety of fruits and vegetables may decrease the risk of squamous cell lung cancer, especially among smokers.
