Studies of human populations and animal models suggest that a father's experiences such as diet or environmental stress can influence the health and development of his descendants. How these effects are transmitted across generations, however, remains mysterious.

A chemist from RUDN was the first to use catalysts with ruthenium nanoparticles to obtain hydrogen under the influence of visible light and UV radiation. In the future, such catalysts may be used for large-scale production of hydrogen fuel under the influence of sunlight. The results of the study were published in Applied Catalysis B: Environmental.

ITHACA, N.Y. - Humans not only relish the sweet, savory and saltiness of foods, but they are influenced by the environment in which they eat. Cornell University food scientists used virtual reality to show how people's perception of real food can be altered by their surroundings, according to research published in the Journal of Food Science.

ANN ARBOR, Mich. -- A trip to the pediatrician's office can be a nerve-wracking experience for both children and their parents, especially when efforts to calm young patients down dominate the visit.

And half of parents of toddler and preschool-aged children can relate, saying their child is afraid of going to the doctor, according to a new report from C.S. Mott Children's Hospital National Poll on Children's Health at the University of Michigan.

When a child gets the flu, they're not only sick in bed for a week or more, but the illness can also have serious and even life-threatening consequences. In fact, 180 children died after contracting the flu during the 2017-2018 season, one of the most severe on record. Despite the consensus of the medical community, a new national survey by Orlando Health Arnold Palmer Hospital for Children finds that a shocking number of parents are still skeptical about the safety and effectiveness of the flu shot.

PITTSBURGH--Smart devices can seem dumb if they don't understand where they are or what people around them are doing. Carnegie Mellon University researchers say this environmental awareness can be enhanced by complementary methods for analyzing sound and vibrations.

In an investigation of head impact burden and change in neurocognitive function during a season of youth football, researchers find that sub-concussive impacts are not correlated with worsening performance in neurocognitive function.

Each year, more than 3 million children in primary and high school play tackle football in the United States. Growing concern about the possible negative effects of repetitive sub-concussive head impacts led to an increased number of physicians and parents who counsel against youth participation in full-contact sports.

Researchers have demonstrated an integrated technique for monitoring specific biomolecules - such as growth factors - that could indicate the health of living cell cultures produced for the burgeoning field of cell-based therapeutics.

Tokyo, Japan - Researchers from Tokyo Metropolitan University have applied machine-learning techniques to achieve fast, accurate estimates of local geomagnetic fields using data taken at multiple observation points, potentially allowing detection of changes caused by earthquakes and tsunamis. A deep neural network (DNN) model was developed and trained using existing data; the result is a fast, efficient method for estimating magnetic fields for unprecedentedly early detection of natural disasters.

RNA has long been the neglected middle child of biomolecules, the go-between between DNA, which encodes the cell's instructions, and proteins, which carry them out. Increasingly, though, researchers are recognizing RNA as a versatile molecule with, possibly, as many functions as proteins have.
