Kids need at least seven minutes a day of 'vigorous' physical activity, but most aren't getting that Posted: 09 Nov 2012 01:20 PM PST Children need a minimum of seven minutes a day of vigorous physical activity, demonstrates a recent study.

Eating of soil and raw starch documented in Madagascar Posted: 09 Nov 2012 01:20 PM PST A new study provides the first population-level data of pica in Madagascar -- the urge to eat dirt, raw starches, chalk, ash and other non-foods. Across the entire sample in the prior year, 53.4 percent engaged in geophagy, eating specific types of earth, including a fine white clay subsoil, fine sand and red river sediment; 85.2 percent ate such raw starches as raw cassava, raw sweet potato, uncooked rice and another local wild root; and 19 percent ate other items considered locally to be nonfood, including rock salt, used coffee grounds, charcoal, rice chaff, blackboard chalk and ash.

New approach to combat viral infections identified Posted: 09 Nov 2012 01:20 PM PST When a virus such as influenza invades our bodies, interferon proteins are among the first immune molecules produced to fight off the attack. A study offers a new strategy for enhancing the effects of interferon in fighting off infection.

Scientists uncover a new pathway that regulates information processing in the brain Posted: 09 Nov 2012 01:20 PM PST Scientists have identified a new pathway that appears to play a major role in information processing in the brain. Their research also offers insight into how imbalances in this pathway could contribute to cognitive abnormalities in humans.

Novel metabolic programs found driving aggressive brain tumors Posted: 09 Nov 2012 10:24 AM PST Researchers have identified metabolic signatures that may pave the way for personalized therapy in glioma, a type of tumor that starts in the brain.

Precision-guided needle used to glue shut dangerous and disfiguring blood vessel growth Posted: 09 Nov 2012 10:23 AM PST Using a rarely performed technique, imaging specialists and surgeons have successfully used precision, image-guided technology to glue shut a tangle of abnormal blood vessel growths in a 43-year-old woman's upper lip, face and nose. Surgery had earlier been ruled out because traditional approaches were considered too risky.

ADHD medicine affects the brain's reward system Posted: 09 Nov 2012 08:15 AM PST Scientists have created a model that shows how some types of ADHD medicine influence the brain's reward system. The model makes it possible to understand the effect of the medicine and perhaps in the longer term to improve the development of medicine and dose determination.

Understanding antibiotic resistance using crystallography and computation Posted: 09 Nov 2012 08:15 AM PST Scientists have solved the structure of an enzyme that breaks down carbapenems , antibiotics 'of last resort' which, until recently, were kept in reserve for serious infections that failed to respond to other treatments.

Scientific explanation to why people perform better after receiving a compliment Posted: 09 Nov 2012 08:15 AM PST Scientists have found scientific proof that people doing exercises appear to perform better when another person compliments them.

How infection can trigger autoimmune disease Posted: 09 Nov 2012 08:15 AM PST Australian scientists have confirmed a 'weak link' in the immune system – identifying the exact conditions under which an infection can trigger an autoantibody response, a process not clearly understood until now.

Hunting neuron killers in Alzheimer's and traumatic brain injury Posted: 09 Nov 2012 08:15 AM PST Levels of the protein appoptosin in the brain skyrocket in Alzheimer's disease and traumatic brain injury. Appoptosin is known for helping the body make heme, the molecule that carries iron in the blood. Researchers discovered that excess heme leads to the overproduction of reactive oxygen species and triggers apoptosis, causing neurons to die.

Link found between child prodigies and autism Posted: 09 Nov 2012 08:12 AM PST A new study of eight child prodigies suggests a possible link between these children's special skills and autism.

Tracking post-Sandy sewage Posted: 09 Nov 2012 08:12 AM PST With millions of gallons of raw sewage dumping into New Jersey waterways following Hurricane Sandy, scientists are using satellites to help predict the sludge's track into the ocean.

Extra chromosome 21 removed from Down syndrome cell line Posted: 09 Nov 2012 06:12 AM PST Scientists succeeded in removing the extra copy of chromosome 21 in cell cultures derived from a person with Down syndrome. Persons with this condition have three copies of this chromosome. The method would not lead to a treatment for Down syndrome, but could lead to treatments for some conditions associated with it, such as leukemia. Comparing tissue development from cell cultures from the same individual, with and without the extra chromosome, could provide clues to developmental delays and early aging problems in Down syndrome.

High-quality personal relationships improve survival in women with breast cancer Posted: 09 Nov 2012 06:11 AM PST The quality of a woman's social networks -- the personal relationships that surround an individual -- appears to be just as important as the size of her networks in predicting breast cancer survival.

Drinking green tea with starchy food may help lower blood sugar spikes Posted: 09 Nov 2012 05:42 AM PST An ingredient in green tea that helps reduce blood sugar spikes in mice may lead to new diet strategies for people, according to food scientists.

Minimally invasive lymph node dissection in breast cancer has advantages over conventional surgery Posted: 09 Nov 2012 05:42 AM PST Axillary lymph node dissection is done in conjunction with lumpectomy or mastectomy to determine if breast cancer has spread to the adjoining lymph nodes. The conventional surgical approach leaves a surgical scar that is unattractive and can restrict range of motion in the shoulder joint. Also, squeezing and pulling the tumor during the breast operation can stimulate tumor cell metastases. A new study reports that an endoscopic technique, mastoscopic axillary lymph node dissection, can reduce these complications.

Total hip replacement surgery increases risk of stroke, study suggests Posted: 09 Nov 2012 05:40 AM PST An international study has shown people who undergo a total hip replacement are at a higher risk of a stroke in the first two weeks after surgery.

An egg a day to keep allergies away? Posted: 09 Nov 2012 05:37 AM PST Avoiding sweet treats like pumpkin bread and cookies this holiday season might not be necessary for children with egg allergies. New studies have found 56 percent of allergic children can tolerate baked hen's egg, while 55 percent outgrow their egg allergy entirely.

Lone star tick inhabiting central and southern U.S. is primary reason for meat induced alpha-gal allergic reaction, study finds Posted: 09 Nov 2012 05:37 AM PST Meat lovers living in the central and southern regions of the United States might be opting for a vegetarian lifestyle if meat comes with an unwanted side of a life-threatening allergic reaction. According to a new study, the lone star tick inhabiting these regions is the primary reason for what's known as a meat induced alpha-gal allergic reaction.

The year 2040: Double the pollen, double the allergy suffering? Posted: 09 Nov 2012 05:37 AM PST With this year's unseasonably warm temperatures and extended seasons, many have coined 2012 as being the worst for allergies. But if you thought your symptoms were worse than ever, just wait until the year 2040. According to a new study, pollen counts are expected to more than double by 2040.

Respiratory symptoms vary according to stage of menstrual cycle Posted: 09 Nov 2012 05:37 AM PST Respiratory symptoms vary significantly during different stages of the menstrual cycle, with higher frequencies during the mid-luteal to mid-follicular stages, according to a new study.
