Earth's most prominent rainfall feature creeping northward
The rain band near the equator that determines the supply of freshwater to nearly a billion people throughout the tropics and subtropics has been creeping north for more than 300 years.

New clue into how brain stem cells develop into cells which repair damaged tissue
The joint research, funded by the National Multiple Sclerosis Society and the UK MS Society as well as the National Institutes of Health and Howard Hughes Medical Institute, was conducted by scientists at the University of California San Francisco (UCSF) and University of Cambridge and was published today (01 July) in the journal Genes and Development.

ADA releases updated position paper on vegetarian diets
The American Dietetic Association has released an updated position paper on vegetarian diets that concludes such diets, if well-planned, are healthful and nutritious for adults, infants, children and adolescents and can help prevent and treat chronic diseases including heart disease, cancer, obesity and diabetes.

Desert rhubarb -- a self-irrigating plant
Researchers from the Department of Science Education-Biology at the University of Haifa-Oranim have managed to make out the "self-irrigating" mechanism of the desert rhubarb, which enables it to harvest 16 times the amount of water than otherwise expected for a plant in this region based on the quantities of rain in the desert.

NIST develops novel ion trap for sensing force and light
Miniature devices for trapping ions (electrically charged atoms) are common components in atomic clocks and quantum computing research. Now, a novel ion trap geometry demonstrated at the National Institute of Standards and Technology (NIST) could usher in a new generation of applications because the device holds promise as a stylus for sensing very small forces or as an interface for efficient transfer of individual light particles for quantum communications.

Alzheimer's research yields potential drug target
Scientists at UC Santa Barbara and several other institutions have found laboratory evidence that a cluster of peptides may be the toxic agent in Alzheimer's disease. Scientists say the discovery may lead to new drugs for the disease.

Blood stem cell growth factor reverses memory decline in mice
A human growth factor that stimulates blood stem cells to proliferate in the bone marrow reverses memory impairment in mice genetically altered to develop Alzheimer's disease, researchers at the University of South Florida and James A. Haley Hospital found.

Lap-band weight-loss surgery can reverse metabolic syndrome in obese teens
A new study of obese adolescents has shown that laparoscopic gastric banding surgery -- the "Lap-Band" procedure -- not only helps them achieve significant weight loss but can also improve and even reverse metabolic syndrome, reducing their risk for cardiovascular disease and diabetes.

Both good/bad movie characters who smoke influence teens to do the same
Dartmouth researchers have determined that movie characters who smoke, regardless of whether they are "good guys" or "bad guys," influence teens to try smoking.

Increasing age of mothers in Spain leads to rise in mortality rates
A new study examining the evolution of maternal mortality rates in Spain since 1996 shows a 17% increase in deaths. This trend is linked to the widespread increase in maternal age. The highest death rates are among foreign women and those who live in the province of Malaga.
