Insights gained from growing cold-causing virus on sinus tissue
Using sinus tissue removed during surgery at University of Wisconsin Hospital and Clinics, researchers at the University of Wisconsin-Madison have managed to grow a recently discovered species of human rhinovirus, the most frequent cause of the common cold, in culture.

Scripps Research scientists uncover new DNA role in modifying gene function
For years, scientists have thought of DNA as a passive blueprint capable only of producing specific proteins through RNA transcription.

New 2 drug combination for obesity compares favorably with currently approved and emerging weight-loss drugs
A new two drug combination (phentermine and topiramate) achieves more than double the weight loss of orlistat, the only drug approved for the long-term treatment of obesity, and compares favorably with drugs in clinical development reported in Phase 3 trials.

Blueberries may inhibit development of fat cells
The benefits of blueberry consumption have been demonstrated in several nutrition studies, more specifically the cardio-protective benefits derived from their high polyphenol content.

Increased life expectancy discourages religious participation
Churches will continue to attract older congregations as increasing life expectancy encourages people to put off involvement in religion, according to new research.

Dr. Larissa Shimoda to discuss mechanisms of hypoxic pulmonary hypertension
When muscles and organs are deprived of an adequate supply of oxygen, the body's usual responses include increased circulation and slight drop in blood pressure in the blood vessels serving the affected tissue.

Big picture of how interferon-induced genes launch antiviral defenses revealed
For the first time, scientists have carried out a comprehensive, systematic evaluation of the antiviral activity of interferon-induced factors.

Green tea and tai chi enhance bone health and reduce inflammation in postmenopausal women
There is a favorable effect of modest green tea consumption on bone remodeling in this pre-osteoporotic population.

Experimental drug achieves unprecedented weight loss
An investigational combination of drugs already approved to treat obesity, migraine and epilepsy produced up to a 10 percent weight loss in obese individuals participating in a one-year clinical trial, according to researchers at Duke University Medical Center.

Accelerated lab evolution of biomolecules could yield new generation of medicines
Scientists at Harvard University have harnessed the prowess of fast-replicating bacterial viruses, also known as phages, to accelerate the evolution of biomolecules in the laboratory.

Flu helps spread pneumonia
Bacteria that cause pneumonia and meningitis are only able to spread when individuals are infected with flu, says a scientist reporting at the Society for General Microbiology's Spring Conference in Harrogate.

West Antarctic warming triggered by warmer sea surface in tropical Pacific
New research shows that rising sea surface temperatures in the central Pacific Ocean drive atmospheric circulation that has caused some of the largest shifts in Antarctic climate in recent decades.

Mapping the brain: New technique poised to untangle the complexity of the brain
Scientists have moved a step closer to being able to develop a computer model of the brain after developing a technique to map both the connections and functions of nerve cells in the brain together for the first time.

Drinking during pregnancy increases risk of premature birth
Drinking alcohol during pregnancy is associated with an increased risk of miscarriage, premature birth, and low birth weight.
