How body size is regulated: International study discovers ten new genes related to human growth
Scientists are beginning to unravel the question why people distinctly vary in size.

New technique determines that the number of fat cells remains constant in all body types
The radioactive carbon-14 produced by above-ground nuclear testing in the 1950s and '60s has helped researchers determine that the number of fat cells in a human's body, whether lean or obese, is established during the teenage years. Changes in fat mass in adulthood can be attributed mainly to changes in fat cell volume, not an increase in the actual number of fat cells.

A new gene trigger for pregnancy disorder identified
The COMT gene - known already for its role in schizophrenia - has been found to play a role in preeclampsia, according to a report in today's advance on-line issue of Nature.

Men are more likely than women to crave alcohol when they feel negative emotions
Women and men tend to have different types of stress-related psychological disorders. Women have greater rates of depression and some types of anxiety disorders than men, while men have greater rates of alcohol-use disorders than women.

Scientists dig deeper into the genetics of schizophrenia by evaluating microRNAs
Researchers at Columbia University Medical Center have illuminated a window into how abnormalities in microRNAs, a family of molecules that regulate expression of numerous genes, may contribute to the behavioral and neuronal deficits associated with schizophrenia and possibly other brain disorders.

Fruit fly avoidance mechanism could lead to new ways to control pain in humans
At first, fruit flies eat like horses. Hatching inside over-ripe fruit where they were laid, they feed wildly in the sugar-rich environment until nature sends them an offer they can't refuse.

Researchers uncover mechanism of action of antibiotic able to reduce neuronal cell death in brain
Virginia Commonwealth University researchers have discovered how an antibiotic works to modulate the activity of a neurotransmitter that regulates brain functions, which eventually could lead to therapies to treat Alzheimer's disease, Huntington's disease, epilepsy, stroke, dementia and malignant gliomas.

Suspected cause of type 1 diabetes caught
Scientists at Washington University School of Medicine in St. Louis working with diabetic mice have examined in unprecedented detail the immune cells long thought to be responsible for type 1 diabetes.

Study supports reason for concern in childhood and adolescent obesity
Study findings presented at the May 2008 Pediatric Academic Societies and Asian Society for Pediatric Research Joint Meeting indicate that childhood and adolescent obesity negatively impacts vascular endothelial function, which relates to cardiac health.

Feedstock makes a difference in feeding distiller's grains
When it comes to using distiller's grains in finishing rations of High Plains cattle, a Texas AgriLife Research scientist says the type of grain used makes all the difference.

heic0812: The Antennae Galaxies move closer
New research on the Antennae Galaxies using the Advanced Camera for Surveys onboard the NASA/ESA Hubble Space Telescope shows that this benchmark pair of interacting galaxies is in fact much closer than previously thought - 45 million light-years instead of 65 million light-years

Scientists endure Arctic for last campaign prior to CryoSat-2 launch
An international group of scientists has swapped their comfortable offices for one of the most inhospitable environments on the planet to carry out a challenging field campaign that is seen as the key to ensuring the data delivered by ESA's ice mission CryoSat will be as accurate as possible.

Model shows how mutation tips biochemistry to cause Alzheimer's
Your fate can be determined by tiny events. Imagine you live in the city and you walk everywhere to get exercise - you are healthy and not afraid of getting mugged.

Binge drinkers have a disconnect between assessing their driving abilities and reality
While many people believe that alcohol-impaired (AI) drivers are usually alcoholics, in fact, 80 percent of AI incidents are caused by binge drinkers.

Is divorce bad for the parents?
The elderly are cared for by their adult children regardless of their marital status. In a unique study funded by the Economic and Social Research Council, researchers found British adult children help their elderly parents according to current need (i.e. health) rather than past behaviour.

American Pain Society's low back guideline expanded to cover interventional procedures
For low-back pain patients and their doctors, the American Pain Society, www.ampainsoc.org, said today it is expanding its evidence-based, clinical practice guideline on diagnosis and treatment of chronic low back pain to include recommendations on surgery and other interventional treatments.

Female concave-eared frogs draw mates with ultrasonic calls
Most female frogs don't call; most lack or have only rudimentary vocal cords. A typical female selects a mate from a chorus of males and then -silently - signals her beau.

Productivity rises when companies are facing closure
In companies that are slated to be shut down, productivity increases during the phase-out period itself. When management is busy dealing with matters other than daily operations, employees shoulder a greater responsibility for their work-and efficiency is enhanced.
