New study possibly links cognitive and motor delays with 'flat head syndrome' in young babies

In a new study, infants averaging six months of age who exhibited positional plagiocephaly (flat head syndrome) had lower scores than typical infants in observational tests used to evaluate cognitive and motor development. Positional or deformational plagiocephaly may occur when external forces shape an infant's skull while it is still soft and malleable, such as extended time spent lying on a...

Severe sleep apnea decreases frequency of nightmare recall

A study in the Feb. 15 issue of the Journal of Clinical Sleep Medicine shows that patients with severe obstructive sleep apnea (OSA) report a significantly lower frequency of nightmares than patients with mild or no sleep apnea, indicating that OSA suppresses the cognitive experience of nightmare recall.

Treatment for herpes in patients co-infected with herpes and HIV could delay HIV disease progression

Most people who are infected with HIV-1 are dually infected with herpes simplex virus type 2 (HSV2). New research shows that aciclovir, used to treat HSV2, could delay HIV-1 disease progression in patients co-infected with both conditions. The findings are published in an Article Online First and in an upcoming edition of The Lancet--written by Dr Jairam Lingappa, University of Washington,...

Drama or reality TV: Do medical shows depict proper first aid for seizures?

Watching TV medical shows might not be the best way to learn what to do when someone has a seizure. Researchers screened the most popular medical dramas and found that doctors and nurses on the shows responded inappropriately to seizures almost half the time, according to a study released today that will be presented at the American Academy of Neurology's 62nd Annual Meeting in Toronto April 10 to...

Greenland ice loss driven by warming seas: study

Greenland's continent-sized icesheet is being significantly eroded by winds and currents that drive warmer water into fjords, where it carves out the base of coastal glaciers, according to studies released Sunday.

Defective signaling pathway sheds light on cystic fibrosis

In a study that could lead to new therapeutic targets for patients with the cystic fibrosis, a research team from the University of California, San Diego School of Medicine has identified a defective signaling pathway that contributes to disease severity. In the study, published in the journal Nature Medicine, the researchers report that defective signaling for a protein called the peroxisome...

Dental researcher finds switch that turns on the spread of cancer

Reporting in Nature Cell Biology, researchers describe the discovery of a specific protein called disabled-2 (Dab2) that switches on the process that releases cancer cells from the original tumor and allows the cells to spread and develop into new tumors in other parts of the body.

Frictionless supersolid a step closer

Superfluid mixtures of atoms can boil and freeze at ultra-low temperatures - about a billion times lower than room temperature. This freezing can result in the formation of supersolids of atoms that can flow alongside each other without friction, but are still set in a fixed structure, says Dutch researcher Koos Gubbels. His research results are contributing to the understanding of superconductors...

Shifting cellular energy metabolism may help treat cardiovascular disease

Drugs that target the way cells convert nutrients into energy could offer new approaches to treating a range of conditions including heart attack and stroke. Using a new way to screen for potential drugs, a team led by Massachusetts General Hospital (MGH) researchers has identified several FDA-approved agents, including an over-the-counter anti-nausea drug, that can shift cellular energy...
