COLUMBUS, Ohio - Many women in doctoral degree programs in fields like engineering and physics are in a class of their own - and that's not a good thing.

A new study found that the fewer females who enter a doctoral program at the same time, the less likely any one of them will graduate within six years.

In the worst-case scenario - where there's just one woman in a new class - she is 12 percentage points less likely to graduate within six years than her male classmates, the study found.

CORVALLIS, Ore. - Requiring physical activity classes in college encourages sedentary students to become more active, while elective classes tend to draw those who are already motivated, new research from Oregon State University has found.

Patients with chronic lymphocytic leukemia (CLL) who feel more stress also have more cancer cells in their blood and elevated levels of three other markers of more advanced disease.

A new study of 96 patients is the first to link stress with biological disease markers in patients with CLL.

"All four variables we measured are related to prognosis in CLL patients, so they have a lot of relevance," said Barbara L. Andersen, lead author of the study and professor of psychology at The Ohio State University.

Shame on you. These three simple words can have devastating effect on an individual's psyche.

But why is that? How is the feeling of shame generated, and what is its purpose? Some theorists argue that feeling shame is a pathology, a condition to be cured. Others dismiss it as a useless, ugly emotion.

Utilizing new mobile application technology, researchers at The University of New Mexico found that medical cannabis provides immediate symptom relief across dozens of health symptoms with relatively minimal negative side effects.

WASHINGTON D.C. -- The number of deaths associated with the inhalation of wildfire smoke in the U.S. could double by the end of the century, according to new research.

A new study simulating the effects of wildfire smoke on human health finds continued increases in wildfire activity in the continental United States due to climate change could worsen air quality over the coming decades. The number of human deaths from chronic inhalation of wildfire smoke could increase to more than 40,000 per year by the end of the 21st century, up from around 15,000 per year today.

Scientists stunted the puberty of male worms by starving them before they underwent sexual maturation. In a study funded by the National Institutes of Health, the scientists suggested that stress from starvation even days before sexual maturation prevented normal changes in the wiring patterns of key neuronal circuits, which caused adult male worms to act immature.

For the first time, a study has shown a distinction between how risk is cognitively processed by law-abiding citizens and how that differs from lawbreakers, allowing researchers to better understand the criminal mind.

“We have found that criminal behavior is associated with a particular kind of thinking about risk,” said Valerie Reyna, the Lois and Melvin Tukman Professor of Human Development and director of the Cornell University Magnetic Resonance Imaging Facility. “And we have found, through our fMRI capabilities, that there is a correlate in the brain that corresponds to it.”

CHAMPAIGN, Ill. -- A new study finds that 21-month-old infants can distinguish between respect-based power asserted by a leader and fear-based power wielded by a bully.

The study, reported in the Proceedings of the National Academy of Sciences, analyzed infants' eye-gazing behavior, a standard approach for measuring expectations in children too young to explain their thinking to adults. This "violation-of-expectation" method relies on the observation that infants stare longer at events that contradict their expectations.

Asthma patients, with a specific genetic profile, exhibit more intense symptoms following exposure to traffic pollution, according to researchers at the National Institutes of Health and collaborators. The study appeared online in Scientific Reports.
