What would happen if the existing disparities in physical activity levels between youth of lower and higher socioeconomic statuses were eliminated? Previous studies have shown that those between 6-17 years of age in lower socioeconomic groups get on average 10-15% less physical activity than those of higher socioeconomic groups. A new study published in the journal JAMA Health Forum on Mar. 15 shows that eliminating such disparities could end up saving society over $15 billion in direct medical costs and productivity losses. This in turn could end up benefiting all taxpayers, anyone who pays insurance ...

UBC researchers believe a group of killer whales observed hunting marine mammals including sperm whales, as well as a sea turtle, in the open ocean off California and Oregon could be a new population. Based on available evidence, the researchers posit in a new study published in Aquatic Mammals  that the 49 orcas could belong to a subpopulation of transient killer whales or a unique oceanic population found in waters off the coast of California and Oregon. “The open ocean is the largest habitat on our planet and observations of killer whales in ...

Global warming, the long-term warming of Earth’s overall temperature, has greatly accelerated in the last 100 years due to human factors such as the burning of fossil fuels. Along with this trend, certain atmospheric phenomena have also changed, such as typhoons and other types of disastrous weather becoming more intense than before and bringing about more serious impacts. The Boreal Summer Intraseasonal Oscillation (BSISO), one of the most pronounced subseasonal variabilities in the tropics during boreal summer, provides an important basis for subseasonal forecasting. Therefore, it is of great significance to study the BSISO and its changes under global warming. Recently, ...

UVA Health researchers have discovered a potential way to predict which patients with severe COVID-19 are likely to recover well and which are likely to suffer “long-haul” lung problems. That finding could help doctors better personalize treatments for individual patients. UVA’s new research also alleviates concerns that severe COVID-19 could trigger relentless, ongoing lung scarring akin to the chronic lung disease known as idiopathic pulmonary fibrosis, the researchers report. That type of continuing lung damage would mean that patients’ ability to breathe would continue to worsen over time. “We are excited ...

The study covered a total of 10,308 incidents involving shootings by police. The Center is based at the Johns Hopkins Bloomberg School of Public Health. The majority of victims in shootings by police—84 percent overall—were reported as armed with a firearm or other weapon, such as a knife or vehicle, during ...

The origin of COVID-19 is highly debated – most studies have focused on a zoonotic origin, but research from the journal Risk Analysis, examined the likelihood of an unnatural origin (i.e. from a laboratory.) The results indicate a greater likelihood of an unnatural than natural origin of the virus. The researchers used an established risk analysis tool for differentiating natural and unnatural epidemics, the modified Grunow-Finke assessment tool (mGFT) to study the origin of COVID-19. This risk assessment cannot prove the specific origin of COVID-19 but shows that the possibility of a laboratory origin ...

By design, synthetic molecules typically have specific jobs to prevent or accelerate reactions between other molecules. To help control more complicated reactions, researchers may harness spare space in one molecule to synthesize another chemical structure. The host-guest assembly can better induce the specific desired reaction than either component individually — if the scientists designing the assembly get it right.   A multi-institution team based in China has reported a novel cluster — the guest — that nucleated ...

The discovery has the potential to improve both the diagnosis and treatment of the language difficulties. The researchers investigated brain abnormalities in developmental language disorder. This condition, which impacts the development of various aspects of language, is about as common as attention-deficit/hyperactivity ...

By Benjamin Boettner  (BOSTON) — Therapeutic cancer vaccines are a form of immunotherapy in the making that could not only destroy cancer cells in patients, but keep a cancer from coming back and spreading. Multiple therapeutic cancer vaccines are being studied in clinical trials, but despite their promise, they are not routinely used yet by clinical oncologists to treat their patients.  The central ingredient of therapeutic cancer vaccines is antigens, which are preferentially produced or newly produced (neoantigens) by tumor cells and enable a patient’s immune system to search and destroy the cancerous ...

The liver is not only the largest internal organ but also vital for human life as a metabolic center. It also possesses remarkable self-healing powers: even when large portions are removed, such as during surgery, they quickly regenerate in healthy individuals. However, in cases of repeated or chronic injury to the liver tissue, as caused by excessive alcohol consumption or viral hepatitis, this regenerative capacity fails. Scarring occurs, known as fibrosis, where liver cells are replaced by fibrous tissue. The liver hardens and becomes increasingly unable to perform its functions - in the worst case, this leads to liver failure. To ...

It is well known that car safety equipment was originally designed with male-representative bodies in mind. This means women sitting in the front row are more likely to suffer severe or fatal injuries in the case of a crash. They are also more likely to be trapped in crashed cars. Interested in the inequalities of car design and the resulting injuries, a team of researchers in the US has used trauma injury data from car crash victims to evaluate differences in injury patterns typical for males and females. “We found that vehicle crash injury patterns and injury severity differ between men and women. We also show that women are arriving ...
