MIT Researchers Propose New Model For Convective Circulation Within Earth's Mantle
Almost two years after convincing the scientific community that most of the Earth's mantle is uniform in composition, National Science Foundation (NSF)-funded researchers at the Massachusetts Institute of Technology propose a model that may explain why the mantle seems to comprise two dissimilar and separate sections.

Structure Of Fat-Depleting Protein Reveals Important Functional Clues
The three-dimensional structure of ZAG, a protein that revs up fat metabolism, offers new insights into clinical obesity and a wasting disorder that plagues breast cancer patients.

UW-Madison Center One Of Two Sites Nationwide Selected For Clinical Trial Of Cancer Drug
The University of Wisconsin Comprehensive Cancer Center has been chosen as one of two sites in the nation to conduct human tests of endostatin, a promising potential cancer treatment that seems to work in part by disrupting the growth of blood vessels that nourish tumor cells.

ONR Funded Experiments Launch New Field: Non-linear Atom Optics
ONR-funded physicists at the Commerce Department's National Institute of Standards and Technology have opened a new field of physics.

Women Smoking Menthol Cigarettes Have Greater Nicotine Exposure
Women who smoke menthol cigarettes may be more likely to inhale deeper with each drag on their cigarette and potentially take in more nicotine than do smokers of non- menthol cigarettes, new research shows.

New Genetic Findings In Attention Deficit Hyperactivity
Researchers from Trinity College, Ireland, studied a sample of children with attention deficit hyperactivity disorder (ADHD) and their parents and found preferential transmission of alleles at polymorphisms at the dopamine transporter gene (DAT1), dopamine-ß-hydroxylase (DBH) gene and the dopamine D5 receptor (DRD5) gene.

New Class Of Molecular Cues Guides Nervous System Wiring
Investigators in two HHMI laboratories have collaborated to discover new molecular road signs that direct nervous system development.

Lo-Cal Diet Slows Prostate Cancer In Animals, New Research Finds
A low-calorie diet slows the progress of prostate cancer in animals, new research shows.

Glowing Bacteria: DuPont And UD Scientists Detect Poultry Toxin And Other Environmental Contaminants
By harnessing glowing bacteria, scientists at the DuPont Co. and the University of Delaware have created inexpensive biosensors that rapidly detect a key toxin in poultry feed, as well as broad classes of other environmental contaminants, including herbicides and metals.

Statement Of The DFG Concerning "Questions Of Human Embryonic Stem Cells"
The Deutsche Forschungsgemeinschaft (DFG) has passed a statement concerning issues of human embryonic stem cells.

Exercise Is The Best Means Of Weight Control In Teenagers
The best means of tackling the increase in obesity in young people is to encourage them to take exercise rather than go on a diet, according to research by Professor George Patton and colleagues from the University of Melbourne and the Royal Children's Hospital Research Institute in this week's BMJ.
