BOSTON – 2 August, 2011 – Obesity is the main culprit in the worldwide avalanche of type 2 diabetes. But how excess weight drives insulin resistance, the condition that may lead to the disease, is only partly understood. Scientists at Joslin Diabetes Center now have uncovered a new way in which obesity wreaks its havoc, by altering the production of proteins that affect how other proteins are spliced together. Their finding, published in Cell Metabolism, may point toward novel targets for diabetes drugs.

Older women who live in a lower socioeconomic status neighborhood are more likely to exhibit lower cognitive functioning than women who live in more affluent neighborhoods, according to a new RAND Corporation study.

The study, published online by the American Journal of Public Health, is the largest of its type to examine whether living in a poor neighborhood is associated with lower cognitive function.

ST. LOUIS, MO August 2, 2011— Researchers working at The Donald Danforth Plant Science Center have made an another advancement in their efforts to improve the root crop cassava which is a major source of calories to 700 million people worldwide, primarily living in the developing world. A study conducted by Dr. Narayanan N. Narayanan and Dr. Uzoma Ihemere, research scientists working in the lab of Dr. Richard T.

Changes in ocean chemistry due to increased carbon dioxide (CO2) emissions are expected to damage shellfish populations around the world, but some nations will feel the impacts much sooner and more intensely than others, according to a study by scientists at Woods Hole Oceanographic Institution (WHOI).

GALVESTON, Texas — Hydrogen sulfide is a foul-smelling gas with an odor resembling that of rotten eggs. Sometimes called "swamp gas," this toxic substance is generally associated with decaying vegetation, sewers and noxious industrial emissions. And — as odd as it may seem — it also plays a critical role in protecting blood vessels from the complications of diabetes, according to a new study from the University of Texas Medical Branch at Galveston.

PROVIDENCE, R.I. [Brown University] — For all the ills that result from bad parenting, new evidence from an epidemiological study of thousands of people suggests coronary heart disease (CHD) might be added to that list.

"We often think about how the early family psychosocial environment influences the mental health of kids," said Eric Loucks, assistant professor of epidemiology in the Warren Alpert Medical School of Brown University. "The fact that it may be important for chronic diseases, like heart disease, hasn't been thought of as much."

VIB researchers have developed a mouse model for Charcot-Marie-Tooth (CMT) neuropathy, a hereditary disease of the peripheral nervous system. They also found a potential therapy for this incurable disease. The treatment not only halted the damage to the nerves and the atrophy of the muscles, it even succeeded in reversing the symptoms. The research was conducted under supervision of Wim Robberecht en Ludo Van Den Bosch from VIB-K.U.Leuven, in collaboration with the team of Vincent Timmerman at VIB-University of Antwerp. The study was published in Nature Medicine.

Upper aero-digestive tract cancers (UADT), especially those of the oral cavity, pharynx, and larynx, are often referred to as alcohol-related cancers as it has been shown repeatedly that heavy drinkers, in particular, are at increased risk. The combination of heavy alcohol use and cigarette smoking is the key factor in increasing the risk of these cancers.

When it comes to satisfaction with body function and body appearance, older men and women have different opinions, although physical activity does improve satisfaction in both sexes, according to new study by a Baylor University researcher.

A new material that can retain and release heat according to specific temperature requirements could make a significant difference to the cost of heating and cooling buildings, scientists say.

Researchers based at The University of Nottingham Ningbo China (UNNC) believe their invention — which could be used in existing structures as well as new builds — could offer considerable energy savings.

A revolutionary biodegradable pellet which slowly releases antibiotics into the middle ear could transform the lives of thousands of children who suffer from glue ear.

An international team of molecular scientists have discovered that star ascidians, also known as sea squirts, have pacemaker cells similar to that of the human heart. The research, published in the JEZ A: Ecological Genetics and Physiology, may offer a new insight into the early evolution of the heart as star ascidians are one of the closest related invertebrates to mammals.

Marine researchers in New Zealand have identified the direct impact of fishing as the largest known human factor in the decline of the endangered native sea lion population. The team's findings, published in Mammal Review, discount non-human factors, such as disease and identifies resource competition and by-catch incidents as the most likely causes.

Eight out of ten Australians would radically change their behaviour if tests showed they had a genetic susceptibility to depression, a national study has found.

The study, conducted by researchers at the University of New South Wales (UNSW) and published online in the Journal of Affective Disorders, is the first population-wide analysis of Australian attitudes towards genetic testing for risk of mental illness.

Aging brings about a selective decline in the numbers and function of T cells – a type of white blood cell involved in the immune system's response to infection – and T cells that survive the longest may better protect against infections such as the flu, according to a study led by researchers from the University of Arizona College of Medicine – Tucson. The finding may lead to targeting these cells with vaccinations that increase their number and improve protection against disease in older adults.
