National Institutes of Health scientists and their collaborators have identified an internal communication network in mammals that may regulate tissue repair and inflammation, providing new insights on how diseases such as obesity and inflammatory skin disorders develop. The new research is published in Cell.

Researchers from Charité - Universitätsmedizin Berlin and the University of California in San Francisco were able to show for the first time that a very low calorie diet significantly alters the composition of the microbiota present in the human gut. In a current Nature* publication, the researchers report that dieting results in an increase of specific bacteria - notably Clostridioides difficile, which is associated with antibiotic-induced diarrhea and colitis.

Best known for its presence in house cats and a tendency to infect and alter the behaviors of rodents and humans, the parasite Toxoplasma gondii (T. gondii) is also associated with bold behavior among wild hyena cubs and risk of death during interactions with lions, finds new research.

A new study published in the Journal of the Association for Consumer Research posits that increased accessibility to anthropomorphized luck (i.e., "lady luck") can lead consumers to be more likely to pursue higher-risk financial behavior.

During the COVID-19 pandemic, cloth face masks became a way to help protect yourself and others from the virus. And for some people, they became a fashion statement, with many fabric choices available. But just how effective are they, especially in containing a sneeze? Now, researchers reporting in ACS Biomaterials Science & Engineering used high-speed videos of a person sneezing to identify the optimal cloth mask design.

A new biocompatible polymer-based composite material could soon replace metal plates in treating difficult and unstable fractures. Developed at KTH Royal Institute of Technology in Stockholm, the newly-developed material is as strong as dental composites yet non-toxic.

The stink of ammonia in urine, sweat, and rotting meat repels humans, but many insects find ammonia alluring. Now, UConn researchers have figured out how the annoying insects smell it, a discovery that could lead to better ways to make them buzz off.

A new report from the University of Minnesota Medical School's Healthy Youth Development - Prevention Research Center (HYD-PRC) highlights that Minnesota youth continue to contract sexually transmitted infections (STIs) at alarmingly high rates, despite the COVID-19 pandemic.

Researchers from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences have discovered a 120-million-year-old partial fossil skeleton of a tiny extinct bird that fits in the palm of the hand and preserves a unique skull with a mix of dinosaurian and bird features.

MU study finds link between forgiveness, congregational support and neuroimmune biomarkers.

Electrical and computer engineers take on complex modeling questions that can further our understanding of virus spread in small spaces.

A new study provides an in-depth look into the rich diversity of prey that giant plumose anemones consume. This includes a surprising menu item: ants. And the occasional spider.

Psycholinguists from the HSE Center for Language and Brain, in collaboration with researchers from the City University of New York and the University of Stuttgart, investigated how reading in Russian varies among different groups of readers. The authors used a novel method in bilingualism research -- comparison of the eye-movement sequences (scanpaths) in adult native speakers of Russian, Russian-speaking children, and adult bilinguals with different levels of Russian proficiency. The results of the study were published in Reading Research Quarterly.

Black patients with cirrhosis - late-stage liver disease - are about 25% more likely to die compared to non-Hispanic white patients and four times less likely to receive a liver transplant, reports a new study. Estimates of racial disparity in cirrhosis have been limited by a lack of large-scale longitudinal data. The paper is one of the first to link all seven large liver centers in Chicago with the death registry and transplant registry to examine racial disparities in cirrhosis.

Children with obstructive sleep apnea are nearly three times more likely to develop high blood pressure when they become teenagers than children who never experience sleep apnea, according to a new study funded by the National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health.

Researchers at the Universidad Complutense de Madrid and Hospital Clínico San Carlos have designed a mathematical method to measure this. In some layers, wrinkling begins at very early stages of the illness.

Air quality varies greatly within regions and cities around the world, and exposure to air pollution can have severe health impacts. In the US, people of color are disproportionately exposed to poor air quality. A cover story in Chemical & Engineering News, the weekly newsmagazine of the American Chemical Society, highlights how scientists and community activists are using new technologies to gather data that could help address this inequity.

For patients who have inflammatory bowel syndrome (IBS), the condition is literally a pain in the gut. Chronic -- or long-term -- abdominal pain is common, and there are currently no effective treatment options for this debilitating symptom. In a new study in ACS Pharmacology & Translational Science, researchers identify a new potential source of relief: a molecule derived from spider venom. In experiments with mice, they found that one dose could stop symptoms associated with IBS pain.

Pairing blueberry pie with a scoop of ice cream is a nice summer treat. Aside from being tasty, this combination might also help people take up more of the 'superfruit's' nutrients, such as anthocyanins. Researchers reporting in ACS' Journal of Agricultural and Food Chemistry show that α-casein, a protein found in cow's milk, helped rats absorb more blueberry anthocyanins and their byproducts, boosting accessibility to these good-for-you nutrients.

A new blood test could signal whether treatment for metastatic HPV-positive throat cancer is working months earlier than standard imaging scans, allowing doctors to try alternatives sooner, initial results show.
