A doable therapy for COVID-19 and an strategy for creating others — ScienceDaily

SARS-CoV-2, the virus that causes COVID-19 illness is extra transmissible, however has a decrease mortality charge than its sibling, SARS-CoV, in line with a evaluation article revealed this week in Antimicrobial Brokers and Chemotherapy, a journal of the American Society for Microbiology. In people, coronaviruses trigger primarily respiratory infections. People with SARS-CoV-2 might stay asymptomatic for two to 14 days post-infection and a few people doubtless transmit the virus with out creating illness signs. Thus far, essentially the most promising compound for treating COVID-19 is the antiviral, remdesivir. It’s at…

Discovery is important step in creating electronics for excessive power effectivity and harsh environments — ScienceDaily

Researchers on the College of Bristol have give you a brand new sort of nanoelectromechanical relay to allow dependable high-temperature, non-volatile reminiscence. The work, which is reported in Nature Communications, was carried out in collaboration with the College of Southampton and the Royal Institute of Know-how, Sweden. The invention is a vital improvement for all-electric automobiles and more-electric plane which require electronics with built-in information storage that may function in excessive temperatures with excessive power effectivity. As transistor leakage present will increase with temperature, nanoelectromechanical relays have emerged as a…

Stem-cell-derived mannequin of growing mind may enable fast testing of medicine, chemical substances for developmental neurotoxicity — ScienceDaily

Researchers at Johns Hopkins Bloomberg Faculty of Public Well being have demonstrated using stem-cell-derived “mini-brains” to detect dangerous unwanted side effects of a standard drug on the growing mind. Mini-brains are miniature human mind fashions, developed with human cells and barely seen to the human eye, whose mobile mechanisms mimic these of the growing human mind. The scientists, who will publish their findings on February 21 in Frontiers in Mobile Neuroscience, used the mini-brains to find out that the widespread antidepressant paroxetine suppresses the expansion of synapses, or connection factors…

Researchers are growing supplies to assist develop human tissues — ScienceDaily

Rutgers biomedical engineers have developed a “bio-ink” for 3D printed supplies that might function scaffolds for rising human tissues to restore or substitute broken ones within the physique. The examine was revealed within the journal Biointerphases. Bioengineered tissues present promise in regenerative, precision and customized drugs; product growth; and primary analysis, particularly with the arrival of 3D printing of biomaterials that might function scaffolds, or non permanent buildings to develop tissues. Hyaluronic acid, a pure molecule discovered in lots of tissues all through the physique, has many properties excellent for…
