Dry winters linked to seasonal outbreaks of influenza
Epidemiology
The seasonal increase of influenza has long baffled scientists, but a new study published this week in PLoS Biology has found that seasonal changes of absolute humidity are the apparent underlying cause of these wintertime peaks. The study also found that the onset of outbreaks might be encouraged by anomalously dry weather conditions, at least in temperate regions.

Remember magnesium if you want to remember
Neuroscience
Those who live in industrialized countries have easy access to healthy food and nutritional supplements, but magnesium deficiencies are still common. That's a problem because new research from Tel Aviv University suggests that magnesium, a key nutrient for the functioning of memory, may be even more critical than previously thought for the neurons of children and healthy brain cells in adults.

Scientists create tiny RNA molecule with big implications for life's origins
Molecular Biology
An extremely small RNA molecule created by a University of Colorado at Boulder team can catalyze a key reaction needed to synthesize proteins, the building blocks of life. The findings could be a substantial step toward understanding "the very origin of Earthly life," the lead researcher contends.

Ice shelves disappearing on Antarctic Peninsula
Environment
Ice shelves are retreating in the southern section of the Antarctic Peninsula due to climate change. This could result in glacier retreat and sea-level rise if warming continues, threatening coastal communities and low-lying islands worldwide.

Typhoid fever bacteria collect on gallstones to perpetuate disease
Agriculture
A new study suggests that the bacteria that cause typhoid fever collect in tiny but persistent communities on gallstones, making the infection particularly hard to fight in so-called "carriers" – people who have the disease but show no symptoms.

Tumor mechanism identified
Neuroscience
Researchers from the Peninsula Medical School in Plymouth (UK), the Memorial Sloan-Kettering Cancer Center in New York, Cornell University in New York, Weil Medical College in New York and the Center for Neural Tumour Research in Los Angeles, have for the first time identified a key mechanism that makes certain cells become tumorous in the brain. The resulting tumours occur most often spontaneously but can also occur in numbers as part of the inherited disease Neurofibromatosis type 2.

A Bird With a Big Air-Conditioning Bill
When it comes to keeping cool, toucans get top billing in the animal world. New research shows that the colorful bird uses its massive beak to rapidly radiate away heat, allowing it to chill out in tropical climates or when expending a lot of energy while flying. At its most efficient, the toucan is theoretically capable of jettisoning 100% of its overall body heat loss through its bill.
