Adding the nutrient selenium to diets protects against obesity and provides metabolic benefits to mice, according to a study published today in eLife.
The results could lead to interventions that reproduce many of the anti-aging effects associated with dietary restriction while also allowing people to eat as normal.
LAWRENCE -- Recent incidents of racial discrimination and violence against Asians and Asian-Americans in the United States have prompted critical discussions about how to talk about such biases with younger age groups. New research from the University of Kansas shows using critical race media literacy, or examining how race and gender are addressed in popular culture, can be an effective way to discuss those topics and engage students.
Through his role on the U.S. Preventive Services Task Force, UVA Health's Li Li, MD, PhD, MPH, has helped develop new lung cancer screening guidelines that expand screenings to more high-risk patients.
The new guidelines are focused on Americans at higher risk because of their history of smoking, which is the leading cause of lung cancer. There are two significant changes in the new guidelines. For those who are still smoking or quit less than 15 years ago, a yearly screening using a low-dose computed tomography (CT) scan is now recommended:
Most businesses were ill-prepared to deal with the pandemic and muddled though the challenges stemming from it, according to a report published today.
As social media platforms like Instagram, Snapchat, TikTok and others continue to grow in popularity, adolescents are spending more of their time online navigating a complex virtual world.
New research suggests that these increased hours spent online may be associated with cyberbullying behaviors. According to a study by the University of Georgia, higher social media addiction scores, more hours spent online, and identifying as male significantly predicted cyberbullying perpetration in adolescents.
PULLMAN, Wash. - Washington State University researchers have discovered a protein that could be key to blocking the most common bacterial cause of human food poisoning in the United States.
Chances are, if you've eaten undercooked poultry or cross contaminated food by washing raw chicken, you may be familiar with the food-borne pathogen.
(Philadelphia, PA) - The human heart works under high demand, constantly pumping oxygen-rich blood through the body. When faced with disease, however, fulfilling this demand can become increasingly difficult and harmful. In the case of chronic high blood pressure - a leading cardiovascular disease in the United States - the heart continuously overexerts, resulting in maladaptive growth and, ultimately, severe dysfunction of the heart muscle itself.
Mount Sinai researchers have found that a widely available and inexpensive drug targeting inflammatory genes has reduced morbidity and mortality in mice infected with SARS-CoV-2, the virus that causes COVID-19. In a study published today in the journal Cell, the team reported that the drug, Topotecan (TPT), inhibited the expression of inflammatory genes in the lungs of mice as late as four days after infection, a finding with potential implications for treatment of humans.
Research into the diets of a large number of the world's carnivores has been made publicly available through a free, online database created by a PhD student at the University of Sussex.
From stoats in the UK to tigers in India, users are now able to search for detailed information about the diets of species in different geographical locations around the globe.
LOWELL, Mass. - Too often, contends UMass Lowell faculty researcher Brenna Morse, children with complex chronic medical conditions spend days in the hospital undergoing tests for what could be a simple diagnosis.
Giant trees in tropical forests, witnesses to centuries of civilization, may be trapped in a dangerous feedback loop according to a new report in Nature Plants from researchers at the Smithsonian Tropical Research Institute (STRI) in Panama and the University of Birmingham, U.K. The biggest trees store half of the carbon in mature tropical forests, but they could be at risk of death as a result of climate change--releasing massive amounts of carbon back into the atmosphere.
Researchers at Washington University in St. Louis reported the first observations of a new form of fluorine, the isotope 13F, described in the journal Physical Review Letters.
They made their discovery as part of an experiment conducted at the National Superconducting Cyclotron Laboratory at Michigan State University (MSU).
CAMBRIDGE, MA -- More than just a sign of illness, mucus is a critical part of our body's defenses against disease. Every day, our bodies produce more than a liter of the slippery substance, covering a surface area of more than 400 square meters to trap and disarm microbial invaders.
A study conducted at the University of Campinas (UNICAMP) in the state of São Paulo, Brazil, shows that compounds produced by gut microbiota (bacteria and other microorganisms) during fermentation of insoluble fiber from dietary plant matter do not affect the ability of the novel coronavirus SARS-CoV-2 to enter and replicate in cells lining the intestines.
