Previous research was falsely reassuring; captured only 2% of cirrhosis patients
Findings underscore lack of access to health care for Black patients
Cirrhosis is leading cause of death and affects more than 600,000 people in U.S.
CHICAGO --- 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 Northwestern Medicine study.
BUFFALO, N.Y. -- The giant plumose anemone is an animal, but it looks a bit like an underwater cauliflower. Its body consists of a stalk-like column that attaches to rocks and other surfaces on one end, and to a crown of tentacles on the other.
The anemones use these feelers to collect and shove food into their mouths, and a new study provides an in-depth look into the rich diversity of prey the anemones are catching. This includes a surprising menu item: ants, specifically the pale-legged field ant, Lasius pallitarsis. And the occasional spider.
How long do virus-laden particles persist in an elevator after a person infected with COVID-19 leaves? And is there a way to detect those particles? A group of electrical engineers and computer scientists at KAUST set out to answer these questions using mathematical fluid dynamics equations.
"We found1 that virus-laden particles can still be detected several minutes after a short elevator trip by an infected person," says KAUST electrical engineer Osama Amin.
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.
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.
The sense of smell is enormously important. Mammals devote a third of their genetic code to odor receptors found in the nose, and have more than 1,000 different kinds that allow us to smell an estimated trillion different odors.
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 material and a surgical method, which were published in Advanced Functional Materials, will be used in clinical studies in 2023 and 2024, with a focus on hand fractures.
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.
A new article published in the Journal of the Association for Consumer Research presents a neural model of maladaptive consumption.
Newspapers regularly carry stories of terrifying shark attacks, but in a paper published today, Oxford-led researchers reveal their discovery of a 3,000-year-old victim - attacked by a shark in the Seto Inland Sea of the Japanese archipelago.
By José Tadeu Arantes | Agência FAPESP – Mathematical models that describe the physical behavior of magnetic materials can also be used to describe the spread of the novel coronavirus that causes COVID-19.
This is the conclusion of a study conducted in Brazil by researchers affiliated with São Paulo State University (UNESP) in Rio Claro and Ilha Solteira and reported in an article published in Physica A: Statistical Mechanics and its Applications.
Flavoring can change how the brain responds to e-cigarette aerosols that contain nicotine, according to Penn State College of Medicine researchers. Andrea Hobkirk and her team used functional magnetic resonance imaging (MRI) to understand how the brain's reward areas react to e-cigarette aerosol with and without flavor.
Researchers from Bentley University have been exploring how readers at partisan news sites respond to news events that challenge their worldview.
NEW YORK CITY, June 23, 2021 -- From amoebas to zebras, all living things evolve. They change over time as pressures from the environment cause individuals with certain traits to become more common in a population while those with other traits become less common.
Cancer is no different. Within a growing tumor, cancer cells with the best ability to compete for resources and withstand environmental stressors will come to dominate in frequency. It's "survival of the fittest" on a microscopic scale.
Toronto - Last winter, Goldman Sachs reported it was working to make things better after a group of junior analysts revolted against 100-hour work weeks.
That's a smart thing to do, suggests a new study from the University of Toronto's Rotman School of Management. Drawing from more than 6,000 employee reviews of their workplaces and data on their firms' forecasting accuracy, the research shows that making improvements to hardworking analysts' work-life balance produces dividends for the company and for the analysts' careers.
The Gerontological Society of America's highly cited, peer-reviewed journals are continuing to publish scientific articles on COVID-19. The following were published between May 4 and June 14; all are free to access:
