Proteins perform a vast array of functions in the cell of every living organism with critical roles in almost every biological process. Not only do they run our metabolism, manage cellular signaling and are in charge of energy production, as antibodies they are also the frontline workers of our immune system fighting human pathogens like the coronavirus. In view of these important duties, it is not surprising that the activity of proteins is tightly controlled.
Magnetic Resonance Imaging (MRI) images are usually meant to be static. But now, researchers from Mātai Medical Research Institute (Mātai), Stevens Institute of Technology, Stanford University, the University of Auckland and other institutions, report on an imaging technique that captures the brain in motion in real time, in 3D and in stunning detail, providing a potential diagnostic tool for detecting difficult-to-spot conditions such as obstructive brain disorders and aneurysms - before they become life threatening.
BIRMINGHAM, Ala. - Last year, Charles O. Elson, M.D., demonstrated a potential preventive treatment for Crohn's disease, a form of inflammatory bowel disease. He used a mouse model that included immune-reactive T cells from patients with Crohn's disease in a flagellin peptide-specific immunotherapy. This study provided proof-of-principle that a flagellin-directed immunotherapy might provide similar benefits in patients.
Researchers have created a probe that glows when it detects an enzyme associated with issues that can lead to blood clots and strokes.
The team of researchers, from the Department of Chemistry and the National Lung and Heart Institute at Imperial College London, demonstrated that their probe quickly and accurately detects the enzyme in modified E. Coli cells.
Biodiversity is of crucial importance to the marine ecosystem. The prohibition of trawling activities in the Hong Kong marine environment for two and a half years has significantly improved biodiversity, an inter-university study led by City University of Hong Kong (CityU) has found. Research results showed that the trawl ban could restore and conserve biodiversity in tropical coastal waters.
Machine learning algorithms can leverage vast amounts of consumer data, allowing automation of business decisions such as pricing, product offerings, and promotions. Airbnb, an online marketplace for vacation rentals and other lodging, created an algorithm-based smart-pricing tool that is free to all Airbnb hosts and allows hosts to set their properties' daily price automatically. A new study investigated the impact of Airbnb's algorithm on racial disparities among Airbnb hosts.
An Austrian-American research team (University of Vienna, Department Evolutionary Anthropology and Harvard Medical School, Department of Genetics), in collaboration of Hungarian experts from Eötvös Loránd University, has developed a new method that allows the almost non-destructive extraction of genetic material from archaeological human remains. The method allows anthropologists, archaeologists and archaeogeneticists to avoid the risk of serious damage to artefacts of significant scientific and heritage value, which can then be fully examined in future research.
With increased media attention and political campaigns focusing on the gender pay gap, the fact that women -- on average -- are paid less than men, has become an important public discussion. While much of the focus has been on the corporate sector, a new study that looked at executive compensation at nonprofit organizations found that women earn 8.9% less than men with the gap becoming greater when there is room for salary negotiations.
By discovering a potential new cellular mechanism for migraines, researchers may have also found a new way to treat chronic migraine.
Amynah Pradhan, associate professor of psychiatry at the University of Illinois Chicago, is the senior author of the study, whose goal was to identify a new mechanism of chronic migraine, and propose a cellular pathway for migraine therapies. The study, "Neuronal complexity is attenuated in preclinical models of migraine and restored by HDAC6 inhibition, is published in eLife.
Philadelphia, May 6, 2021 - Misunderstanding food date labeling is common and educational communications are needed to improve consumer understanding, according to a new study in the Journal of Nutrition Education and Behavior, published by Elsevier.
(MAY 6, 2021) New York, NY - With around 30 percent of the U.S. population now fully vaccinated, the rate of daily vaccinations has started to slow, raising concerns that greater efforts and investments may be needed to reach higher coverage levels.
WASHINGTON, DC - MAY 6, 2021 - One out of every six adult workers (16%) in the United States are staying in jobs they might otherwise leave out of fear of losing their employer-sponsored health insurance, according to a new West Health-Gallup survey of more than 3,800 U.S. adults.
Measures to contain the Corona pandemic are the subject of politically charged debate and tend to polarize segments of the population. Those who support the measures motivate their acquaintances to follow the rules, while those who oppose them call for resistance in social media. But how exactly do politicization and social mobilization affect the incidence of infection? Researchers at the Max Planck Institute for Human Development have examined this question using the USA as an example. Their findings were published in Applied Network Science.
Honeybees have a complex communication system. Between buzzes and body movements, they can direct hive mates to food sources, signal danger, and prepare for swarming - all indicators of colony health. And now, researchers are listening in.
T-cell acute lymphoblastic leukemia (T-ALL) is a very aggressive type of blood cancer. It is relatively rare but still draws a lot of attention as it mostly develops in children under the age of 20. The standard treatment for T-ALL involves heavy chemotherapy procedures, which result in favorable outcomes with an overall survival of 75% after 5 years.
However, some patients do not respond to this treatment, or they only respond for a short period, after which the disease grows back. These patients therefore need alternative therapies.
