Only one in 30 children does the recommended amount of daily physical activity, new research suggests.
Guidelines from the Chief Medical Officer say people aged five to 18 should do at least 60 minutes of "moderate-to-vigorous intensity physical activity" every day.
Previous research has often used less than seven days of data on children's activity and created an average based on that.
Only a third of European countries have robust reporting on child and adolescent nutrient intakes, new research shows. This highlights the potential lack of data to inform the design and monitoring of nutritional policies in some parts of Europe.
Rick Grimes has nothing on the humble American cockroach when it comes to avoiding zombification.
Far from being a weak-willed sap easily paralyzed by the emerald jewel wasp's sting to the brain - followed by becoming a placid egg carrier and then larvae chow - the cockroach can deliver a stunning karate kick that saves its life, Vanderbilt University biologist Ken Catania found.
Research by the University of Liverpool could help scientists unlock the full potential of new clean energy technologies.
Finding sustainable ways to replace fossil fuels is a key priority for researchers across the globe. Carbon dioxide (CO2) is a hugely abundant waste product that can be converted into energy-rich by-products, such as carbon monoxide. However, this process needs to be made far more efficient for it to work on a global, industrial scale.
New Vanderbilt research finds how long humans and other warm-blooded animals live--and when they reach sexual maturity-- may have more to do with their brain than their body. More specifically, it is not animals with larger bodies or slower metabolic rates that live longer; it is animals with more neurons in the cerebral cortex, whatever the size of the body.
Researchers studying the sharp decline between 1980 and 2010 in documented landings of the four most commercially-important bivalve mollusks - eastern oysters, northern quahogs, softshell clams and northern bay scallops - have identified the causes.
Warming ocean temperatures associated with a positive shift in the North Atlantic Oscillation (NAO), which led to habitat degradation including increased predation, are the key reasons for the decline of these four species in estuaries and bays from Maine to North Carolina.
The future looks challenging for plants. Climate change is forecast to bring widespread drought to parts of the planet already struggling with dry conditions. To mitigate the potentially devastating effects to agriculture, researchers are seeking strategies to help plants withstand extreme environmental hazards including drought and salt stress, a problem exacerbated when irrigated water passes through the soil, depositing salts which can then absorbed by plant roots, lowering their overall productivity.
A genetic defect tied to a variety of neurodegenerative diseases and mental illnesses changes how cells starved of sugar metabolize fatty compounds known as lipids, a new study led by researchers from the Johns Hopkins Bloomberg School of Public Health shows. The finding could lead to new targets to treat these diseases, which currently have no cure or fully effective treatments.
Evidence has been building in recent years that our diet, our habits or traumatic experiences can have consequences for the health of our children - and even our grandchildren. The explanation that has gained most currency for how this occurs is so-called 'epigenetic inheritance' - patterns of chemical 'marks' on or around our DNA that are hypothesised to be passed down the generations. But new research from the University of Cambridge suggests that this mechanism of non-genetic inheritance is likely to be very rare.
ANN ARBOR, Mich. - From games inspired by popular TV shows to digital play labeled as educational, children's apps continue to explode on smartphones and tablets.
But parents may not realize that while their little ones are learning letters and numbers or enjoying virtual adventures, they're also likely being targeted by advertisers.
Ninety-five percent of commonly downloaded apps marketed to or played by children ages 5 and under contain at least one type of advertising, according to a new study led by University of Michigan C.S. Mott Children's Hospital.
In the United States, suicide is twice as common as homicide -- and more often involves firearms -- but public perception is just the opposite.
News reports, movies and TV shows may contribute to the perception of a high risk of firearm homicide, authors of a new study say, leaving a substantial gap between ideas and reality and potentially leading to further danger.
WASHINGTON - Headline issues, from immigration to sexual assault, are causing significant stress among members of Generation Z - those between ages 15 and 21 - with mass shootings topping the list of stressful current events, according to the American Psychological Association's report Stress in America™: Generation Z released today.
Despite these concerns, Gen Z adults who are 18 to 21 years old are the generation least likely to vote in the 2018 midterm elections, the report found.
It may simply be that having a big brain is itself the cause.
That's what doctor and PhD candidate Even Hovig Fyllingen at the Norwegian University of Science and Technology (NTNU) has determined with his research colleagues.
"Aggressive brain cancer is a rare type of cancer, but once you have it, the chance of survival is relatively low," he says.
Lifestyle matters less
BLOOMINGTON, Ind. -- Scientists at Indiana University found high levels of a previously unsuspected pollutant in homes, in an electronic waste recycling facility and in the natural environment. People are likely to be exposed to this pollutant by breathing contaminated dust or through skin contact.
Delivering an effective therapeutic payload to specific target cells with few adverse effects is considered by many to be the holy grail of medical research. A new Tel Aviv University study explores a biological approach to directing nanocarriers loaded with protein "game changers" to specific cells. The groundbreaking method may prove useful in treating myriad malignancies, inflammatory diseases and rare genetic disorders.
