The SARS-CoV-2 virus that causes COVID-19 may have the ability to reactivate dormant tuberculosis (TB). In a novel study scientists report in The American Journal of Pathology that infection with a specific coronavirus strain reactivated dormant Mycobacterium tuberculosis (MTB) in mice. This knowledge may help to develop new vaccines for COVID-19 and avoid a potential global tuberculosis epidemic.
Although each organism has a unique genome, a single gene sequence, each individual has many epigenomes. An epigenome consists of chemical compounds and proteins that can bind to DNA and regulate gene action, either by activating or deactivating them or producing organ- or tissue-specific proteins. As it is a highly dynamic material, it can provide a large amount of information to shed light on the evolution of the various tissues and organs that make up the body.
Researchers have successfully used graphene -- one of the strongest, thinnest known materials -- to detect the SARS-CoV-2 virus in laboratory experiments.
Researchers find an increase in inflammatory molecules in serum and cerebrospinal fluid of C90RF72 patients, informing future anti-inflammatory therapies.
A research team at the University of Chicago is now exploring the properties of a material found in cells which allows cells to remember and respond to environmental pressure. In a paper published on May 14, 2021 in Soft Matter, they teased out secrets for how it works--and how it could someday form the basis for making useful materials.
Scientists at Weill Cornell Medicine have developed a computational technique that greatly increases the resolution of atomic force microscopy, a specialized type of microscope that "feels" the atoms at a surface. The method reveals atomic-level details on proteins and other biological structures under normal physiological conditions, opening a new window on cell biology, virology and other microscopic processes.
Pheromones mediate asymmetric mating behavior in isogamous yeast
Brazilian researchers show that a combination of inflammatory cytokines in the blood and cannabis use, daily or during adolescence, heightens the odds of developing psychiatric disorders.
A new paper in the journal Cognition examines the visual complexity of written language and how that complexity has evolved.
Commonplace pharmaceuticals, such as ibuprofen, can carry with them an inherent flaw in their atomic structure, which pairs the active, beneficial ingredient with a potentially ineffective -- or even toxic -- counterpart. New research could hold the key to more easily isolating the good while removing the unwanted.
