Researchers identify gene for osteoporosis

Researchers report the identification of a gene that may play a role in susceptibility to osteoporosis, the crippling disease that leads to bone fractures, especially of the hip and spine.

Discovery of new cell involved with cancer

Scientists have discovered a new type of cell that appears to play a role in the development of cancer – a highly volatile, precancerous stem cell that can either remain benign or become malignant, depending upon environmental cues.

Everyday plastics and pesticides may influence obesity

Obesity is generally discussed in terms of caloric intake (how much a person eats) and energy output (how much a person exercises).

Bladder urothelium in PBS/IC shows distinct differences in keratin profiles

Research groups from the Netherlands and Denmark led by Pilar Laguna studied urothelial involvement in PBS/IC by characterizing the keratin phenotype of bladder urothelium in 18 patients with the disorder.

Mice more complicated than humans when it comes to telomeres

In terms of their telomeres, mice are more complicated than humans. That's the finding from a recent Rockefeller University study.

Genetic link to community makeup and ecosystem evolution

Genes of one organism not only control the characteristics of that individual but also dictate the behavior of thousands of other organisms in a community.

The inability to recognize faces can be inherited

In the first study to examine whether the inability to recognize faces can be inherited, researchers found that it is in fact a common disorder that runs in families and is one of the most frequent disorders apparently controlled by a defect in a single gene.

Pituitary adenoma predisposition caused by germline mutations in the AIP gene

A recent Finnish study identifies a low-penetrance gene defect which predisposes carriers to intracranial tumors called pituitary adenomas. In particular individuals carrying the gene defect are susceptible to such tumors which secrete growth hormone.

Genetic variations impact sexual desire

New evidence that individual differences in human sexual desire can be attributed to genetic variations has been revealed by a research group headed by a professor of psychology at the Hebrew University of Jerusalem.

Genetic clues to longevity

In a new study, Drs. Gil Atzmon and Nir Barzilai at the Albert Einstein College of Medicine of Yeshiva University have found that people harbor alleles--alternative forms of a gene--that confer the same sort of longevity advantage.

Duke University biologists evolve complex trait in the laboratory

Duke University biologists have evolved a complex trait in the laboratory -- using the pressure of selection to induce tobacco hornworms to evolve the dual trait of turning black or green depending on the temperature during their development.

Aquaporin related to obesity

Dr. Gema Fruhbeck, director of the Metabolic Research Laboratory of the University Hospital of the University of Navarra, has published a commentary in the latest issue of Nature. The article presents aquaporin as a new modulator of the biology of the adipocyte.

HRAS mutation analysis in Costello Syndrome

Gene mutations in the HRAS sequence are present in most patients affected with Costello syndrome, according to a new study in the American Journal of Medical Genetics. The mutations occurred de novo in patients, meaning, they were not observed in their parents' genes.
