The pandemic has made clear the threat that some viruses pose to people. But viruses can also infect life-sustaining bacteria. A research team has developed a test to determine if bacteria are sick, similar to the one used to test humans for COVID-19.
As COVID-19 sweeps the world, related viruses quietly circulate among wild animals. A new study shows how SARS-CoV-2, the virus that causes COVID-19, and SARS-CoV-1, which caused the 2003 SARS outbreak, are related to each other. The work helps scientists better understand the evolution of these viruses, how they acquired the ability to infect humans […]
During the SARS-CoV-2 outbreak, laboratories worldwide have pivoted from their usual research to working to identify new COVID-19 drug and vaccine candidates. This experimental work requires access to clinical isolates and systems that allow genetic manipulation of SARS-CoV-2. A new paper reports an openly available SARS-CoV-2 laboratory research toolkit aimed at increasing availability of these […]
A research team has discovered two new genes potentially involved in Alzheimer's disease. They identified them by exploring which genes were turned on and off in the hippocampus of people who suffered from the disease.
A new study estimates 64 percent of adult COVID-19 hospitalizations in the U.S. may have been prevented if there were less obesity, hypertension, diabetes, and heart failure. The model suggests notable differences by age and race/ethnicity in COVID-19 hospitalizations related to these conditions.
A novel approach to pooled testing could help identify up to 20 times more COVID-19 infections per day than individual testing. Simple pooled designs could be implemented with minimal changes to current testing infrastructures in clinical and public health laboratories.
A modeling study suggests a majority of adult COVID-19 hospitalizations nationwide are attributable to at least one of four pre-existing conditions: obesity, hypertension, diabetes, and heart failure, in that order.
A second study of the injectable anti-obesity medication, semaglutide, has confirmed the large weight losses reported in a study earlier this month, establishing the reliability and robustness of this new drug.
A research group from Mind, Brain, and Behaviour Research Centre (CIMCYC) of the University of Granada (UGR) has been studying the issue of excess weight from a neuroscientific perspective for many years, to determine the precise role played by the brain.
Scientists from the Stanley Manne Children's Research Institute at Ann & Robert H. Lurie Children's Hospital of Chicago demonstrated that a nanotherapy reduces intestinal inflammation and shrinks lesions in a rodent model of severe Crohn's disease.
Metabolic diseases, such as obesity and type 2 diabetes, have risen to epidemic proportions in the U.S. and occur in about 30 percent of the population. Skeletal muscle plays a prominent role in controlling the body's glucose levels, which is important for the development of metabolic diseases like diabetes.
