by University of Copenhagen Researchers at the University of Copenhagen’s Department of Nutrition, Exercise and Sports have demonstrated that physical activity prompts a clean-up of muscles as the protein ubiquitin tags onto worn-out proteins, causing them to be degraded. This prevents the accumulation of damaged proteins and helps keep muscles healthy. Physical activity benefits health...
On Thursday, the US Food and Drug Administration announced that more than two dozen antibody tests sold to Americans have not been proven to work A Mayo Clinic experiment found that half of the ninee antibody tests it analyzed were unreliable Antibody tests detect immune proteins developed in response to an infection and may provide...
UC Riverside engineers are transforming yeast, both the domesticated kind used to make bread and beer and lesser-known wild species, so it can be used in a variety of new ways — including fighting cancer. Yanran Li, a UC Riverside assistant professor of chemical and environmental engineering, is working with the yeast species Saccharomyces cerevisiae...
In Germany about 18 million people suffer from non-alcoholic fatty liver. The causes of this disease are manifold and include environmental as well as genetic factors. DZD researchers have now discovered new genes that play a role in the development of fatty liver. In humans and mice, respectively, the genes IRGM, Ifgga2 and Ifgga4 are...
A simple blood test may help predict which people with multiple sclerosis (MS) will get worse during the following year, according to a study by researchers at Karolinska Institutet in Sweden published online in Neurology, the medical journal of the American Academy of Neurology. “In a disease like MS that is so unpredictable and varies...

Team designs antibody-like receptor proteins that can bind to cytokines, as possible strategy for treating coronavirus and other infections. One of the defining features of Covid-19 is the excessive immune response that can occur in severe cases. This burst of immune overreaction also called a cytokine storm, damages the lungs and can be fatal. A...
CAMBRIDGE, MA — One of the defining features of Covid-19 is the excessive immune response that can occur in severe cases. This burst of immune overreaction, also called a cytokine storm, damages the lungs and can be fatal. A team of MIT researchers has developed specialized proteins, similar in structure to antibodies, that they believe...
When people think of glutamate, the first thing they remember is the flavour enhancer that is often used in Asian cuisine. Glutamate is also an important messenger substance in the nervous system of humans. There it plays a role in learning processes and memory. Some Alzheimer drugs, for example, slow down the progression of the...
A novel system to amplify gene expression signals could be a game-changer for scientists who study the regulatory processes in cells that are central to all life. The Rice University lab of bioscientist Laura Segatori has developed a versatile gene signal amplifier that can do a better job of detecting the expression of target genes...
