Gender stereotypes can hurt children — quite literally. When asked to assess how much pain a child is experiencing based on the observation of identical reactions to a finger-stick, American adults believe boys to be in more pain than girls, according to a new study in the Journal of Pediatric Psychology.

Scientists have used a Nobel-prize winning Chemistry technique on a mixture of metals to potentially reduce the cost of fuel cells used in electric cars and reduce harmful emissions from conventional vehicles.
The researchers have translated a biological technique, which won the 2017 Nobel Chemistry Prize, to reveal atomic scale chemistry in metal nanoparticles. These materials are one of the most effective catalysts for energy converting systems such as fuel cells. It is the first time this technique has been for this kind of research.
University of Oklahoma researchers, led by Courtney Hofman and Rita Austin, in collaboration with the Smithsonian National Museum of Natural History, are addressing the challenges of curating ancient biomolecules and working toward the development and dissemination of best practices. In a recent paper published in the Proceedings of the National Academy of Sciences, Hofman and her collaborators suggest museums play a critical role among stakeholders in ancient biomolecules research and should be responsive to these concerns.
Black holes consume everything that falls within their reach, yet astronomers have spotted jets of particles fleeing from black holes at nearly the speed of light. New computer simulations have revealed what gives these particles such speed: cosmic robbery.
Only a small fraction of people who had non-fatal opioid overdoses in West Virginia received treatment in the aftermath, a new study led by researchers at the Johns Hopkins Bloomberg School of Public Health suggests. The finding, the authors say, represents a missed opportunity to prevent future fatal overdoses in a state that leads the nation in these deaths.
Researchers at the University of Sydney have found that the relationship between the tissue-sucking Varroa mite and virulence of a virus of honey bees, has most likely been misunderstood.
The study challenges the long-held belief that the parasitic Varroa mite - a mite that sucks the tissue of honey bees - transmits the Deformed Wing Virus of honeybees and in doing so changes the virus to make it more virulent and deadly.
New research today published in the European Journal of Neurology has found that women are twice as likely to suffer from severe depression following a stroke than men.
The team of researchers from King's College London followed the progress of symptoms over five years after stroke onset in 2,313 people (1,275 men and 1,038 women).
A team of researchers have solved a 20-year riddle of how a crucial step in the biosynthesis of 'last-resort' antibiotics occurs.
A Massachusetts General Hospital (MGH) research team has found that the overgrowth of connective called fibrosis may block the effectiveness of immunotherapies against metastatic breast cancer. Their report published in PNAS also finds that plerixafor, a drug approved to mobilize blood system stem cells in the treatment of lymphoma and multiple myeloma patients, can reduce fibrosis in both primary and metastatic breast tumors and improve response to immunotherapy in mouse models.
Texas A&M University professor Dr. Jodie L. Lutkenhaus is one step closer to realizing her goal of creating a battery made entirely of polymers, which has the potential to charge and discharge much faster than traditional batteries. Lutkenhaus, an associate professor in the Artie McFerrin Department of Chemical Engineering, has detailed her most recent findings on these polymers in a paper in Nature Materials.
Athens, Ga. - The result of football instant replay video reviews can alter a consumer's perception of a brand, according to a study conducted by researchers at the University of Georgia Grady College of Journalism and Mass Communication.
The upcoming Super Bowl, often referred to as the "Ad Bowl," provides a variety of advertising opportunities, including when officials pause game action to analyze an instant replay video.
A pair of Grady College researchers have linked the outcomes of those football replay reviews to consumers having a positive perception of a brand.
Viruses plague bacteria just as viruses like influenza plague humans.
Some of the largest of these so-called bacteriophages have now been found in the human gut, where they periodically devastate bacteria just as seasonal outbreaks of flu lay humans low, according to a new study led by University of California, Berkeley, scientists.
NBA players who excelled during the first part of their career were able to retain more of their skill as they aged. They also displayed a slower decline in performance after the peak of their career, according to a study published in the Springer journal Behaviour Research Methods.
To address the root causes of poor diets, improve nutrition and reduce dietary inequities in Canada requires a broad approach, combining nutrition and social policies, argues an analysis in CMAJ (Canadian Medical Association Journal) http://www.cmaj.ca/lookup/doi/10.1503/cmaj.180938.
Paradoxically, as overall firearm ownership decreased in U.S. households with young children from 1976 to 2016, the proportion of these families who owned handguns increased. This shift in firearm preferences over decades from mostly rifles to mostly handguns coincided with increasing firearm-mortality rates in young children, researchers report Jan. 28, 2019, in Pediatrics.
