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.
Bees and humans are about as different organisms as one can imagine. Yet despite their many differences, surprising similarities in the ways that they interact socially have begun to be recognized in the last few years. Now, a team of researchers at the University of Illinois Urbana-Champaign, building on their earlier studies, have experimentally measured the social networks of honey bees and how they develop over time.
RIVERSIDE, Calif. -- A team co-led by a scientist at the University of California, Riverside, has developed a method to study how HIV mutates to escape the immune system in multiple individuals, which could inform HIV vaccine design.
What if there is a major earthquake near Cologne? This scenario is the subject of the "Risk Analysis in Civil Protection 2019", whose report was recently submitted to the German Bundestag (document: Bundestag Drucksache 19/23825). In the 125-page document, a group of experts has listed in detail, on the basis of extensive research work, what effects can be expected in the event of strong ground movements.
The uniquely human ability to read is the cornerstone of modern civilization, yet very little is understood about the effortless ability to derive meaning from written words. Scientists at The University of Texas Health Science Center at Houston (UTHealth) have now identified a crucial region in the temporal lobe, know as the mid-fusiform cortex, which appears to act as the brain's visual dictionary. While reading, the ability of the human brain to distinguish between a real word such as "lemur" and a made-up word like "urmle" appears to lie in the way that region processes information.
The Ecological Society of America (ESA) today released a report entitled "Innovative Finance for Conservation: Roles for Ecologists and Practitioners" that offers guidelines for developing standardized, ethical and effective conservation finance projects.
A new study from Lund University in Sweden shows that validated biomarkers can reveal an individual's risk of developing Alzheimer's disease. Using a model that combines the levels of two specific proteins in the blood of those with mild memory impairment, the researchers are able to predict the risk of developing Alzheimer's. The researchers have also developed an app that doctors can use to give patients a risk assessment.
Swansea University research has provided a new insight into the behaviour of nature's own UV sunscreens when they are exposed to other parts of the light spectrum.
Mycosporine-like amino acids (MAAs) provide screening against the damaging effects of ultraviolet radiation in living organisms in our oceans and lakes.
These compounds are known to increase in the environment where levels of UV are high. The uniqueness of these compounds has led to interest from the healthcare industry in the development of more natural sunscreen formulations.
Our gut microbiomes -- the many bacteria, viruses and other microbes living in our digestive tracts -- play important roles in our health and risk for disease in ways that are only beginning to be recognized.
University of California San Diego researchers and collaborators recently demonstrated in older men that the makeup of a person's gut microbiome is linked to their levels of active vitamin D, a hormone important for bone health and immunity.
