Eating a low energy density diet can offset influence of obesity gene

Children who carry a gene strongly associated with obesity could offset its effect by eating a low energy density diet, according to new research from UCL (University College London) and the University of Bristol published in PLoS ONE.

Drugs that act on 'fasting signal' may curb insulin resistance in obese

A report in the March issue of Cell Metabolism , a Cell Press publication, has found that a signal known to play a role during fasting also switches on early in the fat tissue of obese mice as they progress toward type 2 diabetes.

Researchers discover structure-building role for 2 non-coding RNAs

Most of the DNA in the nucleus of each of our cells is converted into RNA, but only a small fraction of these RNA molecules serve as coding templates for the synthesis of proteins.

Diet and lifestyle choices influence cancer survival

Head and neck cancer patients who smoked, drank, didn't exercise or didn't eat enough fruit when they were diagnosed had worse survival outcomes than those with better health habits, according to a new study from the University of Michigan Comprehensive Cancer Center.

A new theory on autism put forward

Scientists at Albert Einstein College of Medicine of Yeshiva University have proposed a sweeping new theory of autism that suggests that the brains of people with autism are structurally normal but dysregulated, meaning symptoms of the disorder might be reversible.

Researchers develop mouse models of leukemia that predict response to chemotherapy

Being able to accurately predict how a given cancer will respond to chemotherapy would spare patients with non-responsive tumors the burden of undergoing toxic and ultimately unhelpful treatment.

CSHL neuroscientists propose project to comprehensively map mammalian brain circuits

Thirty-seven scientists from Cold Spring Harbor Laboratory (CSHL) and 20 other major research institutions in the U.S. and Europe have issued a major challenge to the neuroscience community.

Amniotic fluid may be a new source of stem cells

For the first time, scientists have shown that amniotic fluid (the protective liquid surrounding an embryo) may be a potential new source of stem cells for therapeutic applications. The study was prepublished online on February 12, 2009, in Blood, the official journal of the American Society of Hematology.

Moonlighting immune molecules found in the brain

Molecules assumed to be in the exclusive employ of the immune system have been caught moonlighting in the brain - with a job description apparently quite distinct from their role in immunity.

Hundreds of published studies on natural selection may have drawn incorrect conclusions

Scientists at Penn State and the National Institute of Genetics in Japan have demonstrated that several statistical methods commonly used by biologists to detect natural selection at the molecular level tend to produce incorrect results.

Eye cells believed to be retinal stem cells are misidentified

Cells isolated from the eye that many scientists believed were retinal stem cells are, in fact, normal adult cells, investigators at St. Jude Children's Research Hospital have found.

Environment plays role in hypoplastic left heart syndrome

A congenital heart disease that often leads to death in newborns is significantly more common during the summer, leading researchers to believe that the environment, and not just genes that affect the heart, may play a role in causing "mini-epidemics" of this disease.

New cancer genomics web-based tools provide researchers a powerful new to visualize and analyze data

A Cancer Genomics Browser developed by researchers at the University of California, Santa Cruz, provides a new way to visualize and analyze data from studies aimed at improving cancer treatment by unraveling the complex genetic roots of the disease.

Gene scan shows body's sleep cycle influences numerous physical functions

The pineal gland - integral to setting the body's sleep and wake cycles - may be involved in a broad range of bodily functions, according to a study by researchers at the National Institutes of Health and other institutions.

Gene linked to lupus might explain gender difference in disease risk

In an international human genetic study, researchers at UT Southwestern Medical Center have identified a gene linked to the autoimmune disease lupus, and its location on the X chromosome might help explain why females are 10 times more susceptible to the disease than males.
