Soldiers who desecrate the dead see themselves as hunters Posted: 20 May 2012 07:50 PM PDT Modern day soldiers who mutilate enemy corpses or take body-parts as trophies are usually thought to be suffering from the extreme stresses of battle. But, new research shows that this sort of misconduct has most often been carried out by fighters who viewed the enemy as racially different from themselves and used images of the hunt to describe their actions.

Good news for nanomedicine: Quantum dots appear safe in pioneering study on primates Posted: 20 May 2012 10:39 AM PDT A pioneering study to gauge the toxicity of quantum dots in primates has found the tiny crystals to be safe over a one-year period, a hopeful outcome for doctors and scientists seeking new ways to battle diseases like cancer through nanomedicine.

First, do no harm: Danger in standard treatment for a serious lung disease Posted: 20 May 2012 10:38 AM PDT A combination of three drugs used worldwide as the standard of care for a serious lung disease puts patients in danger of death or hospitalization, and should not be used together to treat the disease, called idiopathic pulmonary fibrosis, according to the surprising results of a rigorous independent study. The findings show the importance of testing treatments that doctors give for any condition -- to see if they truly help, and don't harm, patients.

Prenatal pollution exposure dangerous for children with asthma Posted: 20 May 2012 10:36 AM PDT The link between prenatal exposure to air pollution and childhood lung growth and respiratory ailments is well established, and now a new study suggests that these prenatal exposures can be especially serious for children with asthma.

Children Exposed to Smoking Face Long-Term Respiratory Risks Posted: 20 May 2012 10:36 AM PDT A new study shows that the health risks associated with exposure to environmental tobacco smoke among children whose parents smoke persist well beyond childhood, independent of whether or not they end up becoming smokers.

Experimental bariatric surgery controls blood sugar in rodents with diabetes via novel sensing signals in gut Posted: 20 May 2012 10:35 AM PDT For the first time, scientists have shown that an experimental bariatric surgery can lower blood sugar levels in rats with type 1 diabetes.

New target to battle rheumatoid arthritis Posted: 20 May 2012 10:35 AM PDT Scientists have identified the mechanism by which a cell signaling pathway contributes to the development of rheumatoid arthritis (RA).

Drug found for parasite that is major cause of death worldwide Posted: 20 May 2012 10:35 AM PDT An existing drug has been found to be effective against Entamoeba histolytica. This parasite causes amebic dysentery and liver abscesses and results in the death of more than 70,000 people worldwide each year.

Acid in the brain: New way to look at brain function Posted: 19 May 2012 06:32 PM PDT Researchers have developed an MRI-based method to detect and monitor pH changes in living brains. The new technique provides the best evidence so far that pH changes do occur with normal function in the intact human brain. The team hopes to use the method to investigate the role of pH changes in psychiatric disease, including anxiety and depression.

Indoor navigation system for blind Posted: 18 May 2012 10:27 AM PDT A computer science engineering team has developed an indoor navigation system for people with visual impairments. The researchers have explained how a combination of human-computer interaction and motion-planning research was used to build a low-cost accessible navigation system, called Navatar, which can run on a standard smartphone.

Common antibiotic carries heart risk, study suggests Posted: 16 May 2012 02:42 PM PDT Researchers have discovered a rare, but important risk posed by the antibiotic azithromycin, commonly called a "Z-pack." The study found a 2.5-fold higher risk of death from cardiovascular death in the first five days of taking azithromycin when compared with another common antibiotic or no antibiotics at all.

Brain injury to soldiers can arise from exposure to a single explosion Posted: 16 May 2012 12:24 PM PDT Scientists have found new evidence of chronic traumatic encephalopathy (CTE) in brain tissue from blast-exposed military service personnel. Laboratory experiments demonstrated that exposure to a single blast equivalent to a typical improvised explosive device results in CTE and long-term brain impairments that accompany the disease. They also found that the blast wind, not the shock wave, leads to traumatic brain injury and long-term consequences.

Protective molecule, ACE2, also proving its worth in diabetic patients Posted: 16 May 2012 09:03 AM PDT ACE2, a molecule that has been shown to prevent damage in the heart, is now proving to be protective of the major organs that are often damaged in diabetic patients.

Promising discovery in pursuit of effective lymphoma treatments Posted: 16 May 2012 09:03 AM PDT Researchers have identified a target for slowing the progression of multiple myeloma by using currently available drugs.

Breast cancer effectively treated with chemical found in celery, parsley, mouse study suggests Posted: 16 May 2012 06:38 AM PDT Apigenin, a natural substance found in grocery store produce aisles, shows promise as a non-toxic treatment for an aggressive form of human breast cancer, following a new study. Researchers found apigenin shrank a type of breast cancer tumor that is stimulated by progestin, a synthetic hormone given to women to ease symptoms related to menopause.
