Food like an addictive drug for some people

Researchers in the U.S. have found that the same brain circuits are involved when obese people fill their stomachs as when drug addicts think about drugs and the discovery they say suggests an association between overeating and addiction.

Research implicates brain circuits involved in drug craving and emotional response to food

Researchers at the U.S. Department of Energy's Brookhaven National Laboratory have found new clues to how the brain and the stomach interact with emotions to cause overeating and obesity.

NHGRI funds assessment of public attitudes about population-based studies on genes and environment

The National Human Genome Research Institute (NHGRI) has announced it has awarded $2 million to the Genetics and Public Policy Center of the Berman Bioethics Institute at Johns Hopkins University to conduct a public discussion about future potential large U.S. population-based studies examining the roles of genes and environment in human health.

Faulty gene linked to hair pulling disorder

An unusual and uncommon psychiatric disorder that compels people to pull out their hair is now thought to be caused by a mutant gene.

SUMO1 gene implicated in cleft lip and palate defects

Researchers supported by the National Institutes of Health report in the current issue of the journal Science that a much-studied gene called SUMO1, when under expressed, can cause cleft lip and palate, one of the world's most common birth defects.

New understanding of how cells defend themselves

Biologists at the EPFL (Ecole Polytechnique Federale de Lausanne) have unveiled a new twist in a metabolic pathway that cells use to defend themselves against toxins made by disease-causing bacteria.

Insulin receptor stops progression of Alzheimer's disease

Stimulation of a receptor in the brain that controls insulin responses has been shown to halt or diminish the neurodegeneration of Alzheimer's disease, providing evidence that the disease can be treated in its early stages, according to a study by researchers at Rhode Island Hospital and Brown Medical School.

Direct observations of DNA provides new insights into how genetic material is copied and repaired

"We can monitor the process directly, and that gives us a different perspective," said Roberto Galletto, a postdoctoral scholar at UC Davis and first author on a paper published Sept. 20 on the Web site of the journal Nature.

New target for cancer therapy identified by Australian researchers

A new target for cancer therapy has been identified by Monash University scientists investigating the cell signalling pathways that turn on a gene involved in cancer development.

Leptin could combat type 2 diabetes

University of Florida researchers have discovered the appetite-controlling hormone leptin could also combat type 2 diabetes, a disease that has become a growing problem in the United States as more Americans pack on extra pounds.

Women feel thin models are more elegant, interesting and pleasant

Thin fashion models help sell products because many women feel that putting on weight shows a lack of willpower, a new study says.

Researchers discover clues to the cause of T-cell acute lymphoblastic leukemia

Researchers' discovery of clues to the cause of T-cell acute lymphoblastic leukemia (T-ALL) - a form of pediatric cancer that has a very poor prognosis - could lead to the development of new targeted therapies for this extremely difficult disease.

Nanocantilever biosensors detect multiple genes

Using nanoscale cantilevers in a microfluidics device, a team of European researchers has developed a portable biosensor capable of detecting specific genetic sequences.

Racial discrimination can affect adolescents' development - lead to depression and behavior problems

Racial discrimination in the lives of African-American children can lead to depression and behavior problems in adolescence, but teens who have had close relationships with their parents, friendships focused on positive pursuits and good schooling experiences are less likely to experience these negative effects.

California Bill seeks to restrict payments to egg donors

A California bill seeks to extend to privately funded laboratories a provision under Proposition 71 that says scientists receiving state embryonic stem cell research funds can reimburse egg donors only for their expenses and cannot pay egg donors, the Los Angeles Times reports (Romney, Los Angeles Times, 9/13).

Study extends the number of antigenic peptides that can be produced from a single protein

Understanding medical research problems often relies on the direct, linear relationship between the sequence of a protein and the DNA encoding that protein. In fact, colinearity of DNA and protein sequences is thought to be a fundamental feature of the universal genetic code.
