According to a new study, children exposed to high levels of the common air pollutant naphthalene are at increased risk for chromosomal aberrations (CAs), which have been previously associated with cancer.

Text message reminders to parents about flu vaccinations may help boost the number of children vaccinated, according to researchers at Columbia University Medical Center and NewYork-Presbyterian Hospital.

Overall, 17% of children in the United States are obese, and in inner-city neighborhoods, the prevalence is as high as 25%. While poor diets and physical inactivity are the main culprits, there is new evidence that air pollution can play a role.

Drew Ramsey, coauthor of "The Happiness Diet," believes happiness is achieved when the brain is consistently fed the proper nutrients.

When a psychiatrist sets out to write a diet book, he doesn’t have a slimmer waistline in mind.

Inactivation of Foxo1, a gene important for metabolism generated insulin producing cells in small intestines of newborn mice, as detected by immunofluorescence in red.Drs. Talchai and Accili found that when they turned off a gene known to play a role in cell fate decisions—Foxo1—the progenitor cells also generated insulin-producing cells. More cells were generated when Foxo1 was turned off early in development, but insulin-producing cells were also generated when the gene was turned off after the mice had reached adulthood.

A study by Columbia researchers suggests that cells in the patient’s intestine could be coaxed into making insulin, circumventing the need for a stem cell transplant.

A patient who tested positive for the gene that leads to Huntington’s disease wrestled with a host of questions. Should she have children with her husband, knowing that each baby has a 50-50 chance of inheriting the mutation that causes the degenerative neurological illness?

Worldwide pandemics of influenza caused widespread death and illness in 1918, 1957, 1968, and 2009. A new study examining weather patterns around the time of these pandemics finds that each of them was preceded by La Niña conditions in the equatorial Pacific.
