New screening test can determine whether children have a swallowing disorder
A simple test to swallow three ounces of water can help determine whether a child has the swallowing disorder oropharyngeal dysphagia, establishing for the first time a way to screen for the ailment in children, according to new research published in the February 2009 issue of Otolaryngology - Head and Neck Surgery.

New technology discovery at Mount Sinai Hospital holds promise for improved breast cancer treatment
In a study published by Nature Biotechnology online on Feb.

Daytime impairments in older men with obstructive sleep apnea are related to total sleep time
A study in the Feb. 1 issue of the journal Sleep shows that daytime functional impairments in older men with obstructive sleep apnea (OSA) are largely explained by total sleep time rather than OSA severity.

Single gene lets bacteria jump from host to host
All life -- plants, animals, people -- depends on peaceful coexistence with a swarm of microbial life that performs vital services from helping to convert food to energy to protection from disease.

Nanoscopic static electricity generates chiral patterns
Researchers at Northwestern University in the group of Monica Olvera de la Cruz, professor of materials science and engineering and chemical and biological engineering at the McCormick School of Engineering and Applied Science, have recently shown how electrostatic interactions -- commonly known as static electricity -- alone can give rise to helical shapes.

Study suggests that inflammation may be the link between extreme sleep durations and poor health
A study in the Feb. 1 issue of the journal Sleep shows that sleep duration is associated with changes in the levels of specific cytokines that are important in regulating inflammation.

Penn study finds link between Parkinson's disease genes and manganese poisoning
A connection between genetic and environmental causes of Parkinson's disease has been discovered by a research team.

Pregnancy-related hormonal changes linked to increased risk of restless legs syndrome
A study in the Feb. 1 issue of the journal Sleep shows that the elevation in estradiol levels that occurs during pregnancy is more pronounced in pregnant women with restless legs syndrome than in controls.

Results of the third school nutrition dietary assessment study published
A special supplement to the February 2009 issue of the Journal of the American Dietetic Association presents findings from the recently released Third School Nutrition Dietary Assessment Study (SNDA-III), conducted by Mathematica Policy Research, Inc., as well as research from other studies using SNDA-III data.

Stanford study prevents pancreatic tumor growth in mice by inhibiting key protein
Researchers at Stanford University School of Medicine have identified a protein critical for the growth of pancreatic cancer.

Removing some cloud seeds of doubt
A team of researchers at Monash University has released a new analysis of precipitation records from the long-term cloud seeding operation in Tasmania that shows a promising increase in rainfall during periods of seeding.

In India: A search for more effective tuberculosis drugs
Rajesh Gokhale has created a compound in his lab in India that stops tuberculosis by hitting four of the bacterium's crucial metabolic pathways at the same time, weakening and ultimately destroying the pathogen.

Ancient turtle migrated from Asia to America over a tropical Arctic
In Arctic Canada, a team of geologists from the University of Rochester has discovered a surprise fossil: a tropical, freshwater, Asian turtle.

Study finds genetic link between sleep disorders and depression in young children
A study in the Feb. 1 issue of the journal Sleep was the first to use twin data to examine the longitudinal link between sleep problems and depression.

Infliximab may help prevent post-operative Crohn's disease recurrence
The administration of infliximab after intestinal resective surgery was found to be effective at preventing endoscopic and histological recurrence of Crohn's disease.

Scientists uncover new class of nonprotein coding genes in mammals with key functions
Researchers have uncovered a vast new class of previously unrecognized mammalian genes that do not encode proteins, but instead function as long RNA molecules, and seem to play critical roles in both health and disease, including cancer, immune signaling and stem cell biology.

Australian first for Melbourne stem cell scientists
Melbourne scientists have created Australia's first induced pluripotent stem cell lines.
