Northern Eurasian snowpack could be a predictor of winter weather in US, team from UGA reports

Every winter, weather forecasters talk about the snow cover in the northern U.S. and into Canada as a factor in how deep the deep-freeze will be in the states. A new study by researchers at the University of Georgia indicates they may be looking, at least partially, in the wrong place.

It turns out that snow piling up over a band of frozen tundra from Siberia to far-northern Europe may have as much effect on the climate of the U.S. as the much-better-known El Niño and La Niña.

Safer and more effective diabetes control with basal insulin analogs

New Rochelle, NY, June 24, 2011—Basal insulin analogs have revolutionized diabetes care, and especially the treatment of type 2 diabetes, enabling patients to achieve better control of blood glucose levels while reducing hypoglycemic episodes. These revolutionary, long-acting basal insulin analogs, intended to replace the natural insulin missing in diabetes, and infusion pumps that provide subcutaneous, continuous delivery of insulin to mimic the function of a normal pancreas, are described in a special supplement to Diabetes Technology & Therapeutics./p>

Deep history of coconuts decoded

The coconut (the fruit of the palm Cocos nucifera) is the Swiss Army knife of the plant kingdom; in one neat package it provides a high-calorie food, potable water, fiber that can be spun into rope, and a hard shell that can be turned into charcoal. What's more, until it is needed for some other purpose it serves as a handy flotation device.

Invest in children's health, urges former US Surgeon General

New Rochelle, NY, June 24, 2011—David Satcher, MD, PhD, former U.S. Surgeon General, describes childhood obesity as "one of the greatest threats to child and adult health that we are facing today," calling for an intensive effort to promote child health, in an editorial in the June issue of Childhood Obesity, a peer-reviewed journal published by Mary Ann Liebert, Inc. The editorial is available online.

Ancient species of mayfly had short, tragic life

CORVALLIS, Ore. – About 100 million years ago, a tiny mayfly had a problem.

Like most adult mayflies, she only had that one day to live anyway, so there was no time to waste. She took her mating flight, got fertilized, and was about to lay her eggs when something went horribly wrong. She got stuck in some oozing tree sap and died, preserved for all time in the magic of amber. There would be ho hatchlings.

New genetic risk factors of lupus found in study of African-American women

(Boston) - Researchers from Boston University's Slone Epidemiology Center have found four new genetic variants in the major histocompatibility complex (MHC) that confer a higher risk of systemic lupus erythemathosus ("lupus") in African American women. The study, which currently appears on-line in Human Genetics, is believed to be the first to comprehensively assess the association between genetic variants in the MHC region and risk of lupus in African American women.

The mechanics of speciation

Mate choice, competition, and the variety of resources available are the key factors influencing how a species evolves into separate species, according to a new mathematical model that integrates all three factors to reveal the dynamics at play in a process called sympatric speciation.

Titled "Factors influencing progress toward sympatric speciation," the paper appears in today's edition of the Journal of Evolutionary Biology.

Mantis shrimp eye could improve high-definition CDs, DVDs

The eye of the peacock mantis shrimp has led an international team of researchers to develop a two-part waveplate that could improve CD, DVD, blu-ray and holographic technology, creating even higher definition and larger storage density.

Peacock mantis shrimp are one of only a few animal species that can see circularly polarized light -- like the light used to create 3-D movies. Some researchers believe the mantis shrimp's eyes are better over the entire visual spectrum than any man-made waveplates.

Pollinators make critical contribution to healthy diets

Fruits and vegetables that provide the highest levels of vitamins and minerals to the human diet globally depend heavily on bees and other pollinating animals, according to a new study published in the international online journal PLoS ONE.

Singapore scientists discover how to control fate of stem cells

Scientists from the Genome Institute of Singapore (GIS), an institute of the Agency for Science, Technology and Research (A*STAR), in collaboration with the Cancer Science Institute of Singapore (CSI), have discovered how the body uses a single communication system to decide the fate of stem cells. The study, published in the scientific journal PLoS Genetics on 23rd June 2011, paves the way for the development of new methods of stem cell therapy with fewer side effects.

Menthol cigarettes marketed in 'predatory' pattern, Stanford study shows

STANFORD, Calif. - Tobacco companies increased the advertising and lowered the sale price of menthol cigarettes in stores near California high schools with larger populations of African-American students, according to a new study from the Stanford School of Medicine.

Although cigarette makers have denied using race or ethnicity to target customers, the lead researcher for the study said the data shows a "predatory" marketing pattern geared to luring young African Americans into becoming smokers.

Adolescents' dieting and disordered eating behaviors continue into young adulthood

Philadelphia, PA, June 24, 2011 – Adolescents who diet and develop disordered eating behaviors (unhealthy and extreme weight control behaviors and binge eating) carry these unhealthy practices into young adulthood and beyond, according to a study conducted by University of Minnesota researchers and published in the July 2011 issue of the Journal of the American Dietetic Association.

Exposure to parental stress increases pollution-related lung damage in children

Psychosocial stress appears to enhance the lung-damaging effects of traffic-related pollution (TRP) in children, according to new research from the Keck School of Medicine of the University of Southern California (USC) in Los Angeles.

The results will appear online ahead of the print edition of the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.

Rotavirus vaccine greatly reduced gastroenteritis hospitalizations in children

[EMBARGOED FOR JUNE 24, 2011] Vaccination against rotavirus, a major cause of severe acute gastroenteritis in children, dramatically decreased hospitalization rates for the infection among infants in three U.S. counties, according to a new study published in Clinical Infectious Diseases and now available online (http://www.oxfordjournals.org/our_journals/cid/prpaper.pdf).

Oxytocin promises hope in Prader-Willi syndrome

Prader-Willi syndrome is a rare genetic disorder which affects one child in 25,000. Children born with this syndrome have a range of complex neurological and developmental problems which continue into adult life. These can manifest as cognitive and behavioral difficulties, weight gain, problems in controlling their temper and attendant difficulties in socialization.
