When we use a mental shortcut to decide which product we want, we don't always end up with our ideal choice, according to a new study in the Journal of Consumer Research.

In the United States, nearly 13 percent of adults age 20 and older have diabetes, but 40 percent of them have not been diagnosed, according to epidemiologists from the National Institutes of Health (NIH) and the Centers for Disease Control and Prevention (CDC), whose study includes newly available data from an Oral Glucose Tolerance Test (OGTT). Diabetes is especially common in the elderly: nearly one-third of those age 65 and older have the disease. An additional 30 percent of adults have pre-diabetes, a condition marked by elevated blood sugar that is not yet in the diabetic range.

Tampa, FL (Jan. 26, 2009) – There is hope that the drug rasagiline can do what no other medication for Parkinson's disease now does -- slow the progression of a devastating degenerative brain disease that eventually robs people of their ability to move and function.

A new study by researchers at NYU Langone Medical Center found a high desire for additional genetic testing among consumers for life altering and threatening medical conditions including mental retardation, blindness, deafness, cancer, heart disease, dwarfism and shortened lifespan from death by 5 years of age. Consumers, however, are less interested in prenatal genetic testing for traits including tall stature, superior athletic ability and superior intelligence.

A new psychodynamic approach to bullying in schools has been successfully trialled by UCL (University College London) and US researchers. CAPSLE (Creating a Peaceful School Learning Environment) is a groundbreaking method focused more on the bystander, including the teacher, than on the bully or the victim. The study, published in the Journal of Child Psychology and Psychiatry, shows that an easily implemented school-wide intervention focussing on empathy and power dynamics can reduce children's experiences of aggression in school and improve classroom behaviour.

DALLAS – Jan. 25, 2009 – Individual nerve cells in the front part of the brain can hold traces of memories on their own for as long as a minute and possibly longer, researchers at UT Southwestern Medical Center have found.

New Haven, Conn. — The movement of facial skin and muscles around the mouth plays an important role not only in the way the sounds of speech are made, but also in the way they are heard according to a study by scientists at Haskins Laboratories, a Yale-affiliated research laboratory.

"How your own face is moving makes a difference in how you 'hear' what you hear," said first author Takayuki Ito, a senior scientist at Haskins.

A joint team of researchers at CIC nanoGUNE (San Sebastian, Spain) and the Max Planck Institutes of Biochemistry and Plasma Physics (Munich, Germany) report the non-invasive and nanoscale resolved infrared mapping of strain fields in semiconductors. The method, which is based on near-field microscopy, opens new avenues for analyzing mechanical properties of high-performance materials or for contact-free mapping of local conductivity in strain-engineered electronic devices (Nature Nanotechnology, advanced online publication, 11 Jan. 2009).

New research from Monash University bee researcher Adrian Dyer could lead to improved artificial intelligence systems and computer programs for facial recognition.

Dr Dyer is one of Australia's leading bee experts and his latest research shows that honeybees can learn to recognise human faces even when seen from different viewpoints.

Dr Dyer said the research could be applied in the areas of new technology, particularly the development of imaging systems.

ATLANTA--Since the introduction of the life-saving clot-busting drug tPA more than a decade ago, evidence has been accumulating that tPA (tissue-type plasminogen activator) can be a double-edged sword for a brain affected by stroke. Although it remains the only FDA-approved treatment for acute stroke, tPA can also contribute to inflammation and brain cell damage.

Non-verbal communication, in the form of facial expressions, may be impaired in people with schizophrenia. Researchers writing in BioMed Central's open access journal Behavioral and Brain Functions have shown that deficits in non-verbal expressivity in schizophrenia are linked to poor social skills and an unawareness of the thoughts and intentions of others.

PHILADELPHIA –- Living with a female mouse can extend the reproductive life of a male mouse by as much as 20 percent, according to a study conducted by Ralph Brinster and a team of other researchers at the University of Pennsylvania School of Veterinary Medicine. The study was reported online today in the journal Biology of Reproduction.

PROVIDENCE, R.I. [Brown University] — Brown University researchers have identified a cellular mechanism that could someday help fight the aging process.

The finding by Stephen Helfand and Nicola Neretti and others adds another piece to the puzzle that Helfand, a professor of biology, molecular biology, cell biology and biochemistry, first discovered in 2000. Back then, he identified a mutation in the Indy ("I'm Not Dead Yet") gene that can extend the life span of fruit flies.

SALT LAKE CITY – University of Utah scientists identified a worm gene that is essential for damaged nerve cells to regenerate, and showed they could speed nerve regeneration by over-activating the gene – a step toward new treatments for nerves injured by trauma or disease.

Oddly, the gene and a related "pathway" – a chain of molecular events – is not required for normal nerve development in embryos, the researchers report in the Jan. 22 issue of Science Express, the online edition of the journal Science.

New research into language evolution suggests most Pacific populations originated in Taiwan around 5,200 years ago.

Scientists at The University of Auckland have used sospisticated computer analyses on vocabulary from 400 Austronesian languages to uncover how the Pacific was settled.
