Chemical probe confirms that body makes its own rotten egg gas, H2S, to benefit health Posted: 18 Jun 2013 10:18 AM PDT A new study confirms directly what scientists previously knew only indirectly -- that poisonous "rotten egg" gas hydrogen sulfide is generated by the body's blood vessel cells. Researchers made the confirmation by developing a chemical probe that lights up in reaction to rotten egg gas. The scientists observed the process in real-time through a microscope.

Fiber-optic pen helps see inside brains of children with learning disabilities Posted: 18 Jun 2013 10:18 AM PDT For less than $100, researchers have designed a computer-interfaced drawing pad that helps scientists see inside the brains of children with learning disabilities while they read and write.

Getting enough sleep could help prevent type 2 diabetes Posted: 18 Jun 2013 10:18 AM PDT Getting more sleep increases insulin sensitivity and reduces the risk of type 2 diabetes.

Early-life air pollution linked with childhood asthma in minorities Posted: 18 Jun 2013 10:18 AM PDT Scientists have found that exposure in infancy to nitrogen dioxide (NO2), a component of motor vehicle air pollution, is strongly linked with later development of childhood asthma among African Americans and Latinos.

Herbal extract boosts fruit fly lifespan by nearly 25 percent Posted: 18 Jun 2013 09:51 AM PDT The herbal extract of a yellow-flowered mountain plant long used for stress relief was found to increase the lifespan of fruit fly populations by an average of 24 percent, according to researchers.

Timing of calcium and vitamin D supplementation may affect how bone adapts to exercise Posted: 18 Jun 2013 09:50 AM PDT Taking calcium and vitamin D before exercise may influence how bones adapt to exercise, according to a new study.

Beliefs about causes of obesity may impact weight, eating behavior Posted: 18 Jun 2013 08:38 AM PDT Whether a person believes obesity is caused by overeating or by a lack of exercise predicts his or her actual body mass, according to new research.

New resistance mechanism to chemotherapy in breast and ovarian cancer Posted: 18 Jun 2013 08:38 AM PDT A new study explains why tumors with BRCA1 and BRCA2 mutations stop responding to PARP inhibitor drugs.

Nanog protein promotes growth of head and neck cancer Posted: 18 Jun 2013 08:38 AM PDT Researchers have identified a biochemical pathway in cancer stem cells that is essential for promoting head and neck cancer. The study shows that a protein called Nanog, which is normally active in embryonic stem cells, promotes the growth of cancer stem cells in head and neck cancer. The findings provide information essential for designing novel targeted drugs that might improve the treatment of head and neck cancer.

Storytelling program helps change medical students' perspectives on dementia Posted: 18 Jun 2013 08:38 AM PDT Treating patients with dementia can be viewed as a difficult task for doctors, but researchers say that storytelling may be one way to improve medical students' perceptions of people affected by the condition. Participation in a creative storytelling program called TimeSlips creates a substantial improvement in student attitudes.

New approach to battling tuberculosis Posted: 18 Jun 2013 08:36 AM PDT Scientists have discovered a drug that cripples tuberculosis bacteria (Mycobacterium tuberculosis) in a novel way, by dissolving the protecting fatty coating of the bacteria. The drug killed the bacterium in culture without the emergence of drug resistance.

Parenting and home environment influence children's exercise and eating habits Posted: 18 Jun 2013 08:36 AM PDT Kids whose moms encourage them to exercise and eat well, and model those healthy behaviors themselves, are more likely to be active and healthy eaters, according to researchers. Their findings remind parents that they are role models for their children, and underscore the importance of parental policies promoting physical activity and healthy eating.

Iodine in bread not enough for pregnant women Posted: 18 Jun 2013 08:36 AM PDT Iodized salt used in bread is not enough to provide healthy levels of iodine for pregnant women and their unborn children, new research shows.

New virus isolated from patients with severe brain infections Posted: 18 Jun 2013 07:17 AM PDT A new study describes a new virus isolated from patients with severe brain infections. Further research is needed to determine whether the virus is responsible for the symptoms of disease.

Exposure to high pollution levels during pregnancy may increase risk of having child with autism Posted: 18 Jun 2013 07:17 AM PDT Women in the US exposed to high levels of air pollution while pregnant were up to twice as likely to have a child with autism as women who lived in areas with low pollution.

Whooping cough has lifelong health impact, study finds Posted: 18 Jun 2013 07:16 AM PDT People born during whooping cough outbreaks are more likely to die prematurely even if they survive into adulthood, new research has found. Women had a 20% higher risk of an early death, and men a staggering 40%. Women also suffered more complications during and after pregnancy, with an increased risk of miscarriage as well as infant death within the first month of life.

Chemical nanoengineering: Designing drugs controlled by light Posted: 18 Jun 2013 07:15 AM PDT A new breakthrough will help with the development of light-regulated therapeutic molecules.

Potential genetic drivers behind male heart disease risk Posted: 18 Jun 2013 07:15 AM PDT University of Leicester scientists have discovered a potential genetic contributor to the increased risk of heart disease among men.

Aspirin may fight cancer by slowing DNA damage Posted: 18 Jun 2013 07:11 AM PDT Aspirin is known to lower risk for some cancers, and a new study points to a possible explanation, with the discovery that aspirin slows the accumulation of DNA mutations in abnormal cells in at least one pre-cancerous condition.

IQ link to baby's weight gain in first month Posted: 18 Jun 2013 07:11 AM PDT New research shows that weight gain and increased head size in the first month of a baby's life is linked to a higher IQ at early school age.

Rotavirus vaccine given to newborns in africa is effective Posted: 17 Jun 2013 11:20 AM PDT Scientists have shown that a vaccine given to newborns is at least 60 percent effective against rotavirus in Ghana. Rotavirus causes fever, vomiting and diarrhea, which in infants can cause severe dehydration. In developed nations, the condition often results in an emergency room visit or an occasional hospitalization, but is rarely fatal. In developing countries, however, rotavirus-related illness causes approximately 500,000 deaths per year.
