A repurposed mouse model can develop symptoms of both severe COVID-19 (lung damage, blood clots, abnormal blood vessels, and death) and also of milder disease, including loss of the sense of smell, according to a recent University of Iowa study published in Nature.
The study also showed that convalescent plasma from a patient who had recovered from COVID-19 protected the mice against lethal disease. The findings suggest the K18-hACE2 mouse model is useful for understanding a spectrum of COVID-19 disease symptoms, and for developing and testing new treatments.
Nanoengineers at the University of California San Diego have developed new and improved probes, known as positive controls, that could make it easier to validate rapid, point-of-care diagnostic tests for COVID-19 across the globe.
The positive controls, made from virus-like particles, are stable and easy to manufacture. Researchers say the controls have the potential to improve the accuracy of new COVID-19 tests that are simpler, faster and cheaper, making it possible to expand testing outside the lab.
Current research predicts that by 2025, 1,800 million people are expected to be living in countries or regions with insufficient water resources, and models show increased severity of droughts in years to come. Food insecurity and other consequences of droughts will become intensified, influencing disease vulnerabilities among populations in less-developed countries.
It is conventional to believe that the police role in society centers on violence. A forthcoming article in the December issue of Current Anthropology explores that belief and shows how the weakness of police power can be treated as an index for the strength of democratic values institutionalized in the wider political environment.
BINGHAMTON, NY -- In the lizard world, flashy colors attract the interest of females looking for mates. But they can make colorful males desirable to other eyes, too -- as lunch.
BINGHAMTON, NY -- Bacterial infections have become one of the biggest health problems worldwide, and a recent study shows that COVID-19 patients have a much greater chance of acquiring secondary bacterial infections, which significantly increases the mortality rate.
Overcrowding in emergency rooms is a costly and concerning global problem, compromising patient care quality and experience. In a new study, a researcher from The University of Texas at Dallas investigated whether telemedicine could enhance ER care delivery.
"This longstanding problem is mainly driven by the imbalance between increasing patient flow and the shortage of emergency room capacity," said Dr. Shujing Sun, assistant professor of information systems in the Naveen Jindal School of Management and lead author of the study.
We take for granted the fact that feelings such as love, happiness, or pain are described with different words and expressions across languages. But are these differences in the ways we express these feelings in different languages also tied to differences in the sensations themselves? Would a painful event like a stubbed toe or a bee sting hurt less if a bilingual chose to describe or think about it in Spanish as opposed to English?
While the mesmerizing blobs in a classic lava lamp may appear magical, the colorful shapes move in response to temperature-induced changes in density and surface tension. This process, known as liquid-liquid phase separation, is critical to many functions in living cells, and plays a part in making products like medicines and cosmetics.
When humans have low iron levels, they tend to feel weak, fatigued and dizzy. This fatigue prevents patients with iron-deficient anemia from exercising or exerting themselves in order to conserve energy.
WASHINGTON--The number of wildfires and the amount of land they consume in the western U.S. has substantially increased since the 1980s, a trend often attributed to ongoing climate change. Now, new research finds fires are not only becoming more common in the western U.S. but the area burned at high severity is also increasing, a trend that may lead to long-term forest loss.
(Philadelphia, PA) - Taking a major step forward in HIV research, scientists at the Lewis Katz School of Medicine at Temple University have successfully edited SIV - a virus closely related to HIV, the cause of AIDS - from the genomes of non-human primates. The breakthrough brings Temple researchers and their collaborators closer than ever to developing a cure for human HIV infection.
When medically complex children are hospitalized, linking hospitalists to their regular outpatient providers through an inpatient consultation service were more likely to improve outcomes, according to researchers at The University of Texas Health Science Center at Houston (UTHealth).
Results from the quality improvement trial, which showed the inpatient consultation service was more likely to reduce total hospital days, hospital admissions and readmissions, days in pediatric intensive care (PICU), and health care system costs, were published today in JAMA Pediatrics.
Under the worst-case scenarios laid out in the United Nations’ climate change projections, global temperatures could increase as much as 7.2 degrees Fahrenheit (more than 4 degrees Celsius) by 2100, leading to as much as 3 feet (0.98 meters) in global sea level rise and an array of disastrous consequences for people and planet.
COLUMBUS, Ohio - Imagine seeing an image of a cat in front of a wide scene of mountains and being told just to remember the mountains if you saw them in a later picture. As an adult, that's not hard to do.
But a new study shows that, even when told to pay attention to the mountain, preschool children focus so much on the cat that they won't later recognize the same mountain.
