In satellite photos of the Earth, clouds of bright green bloom across the surface of lakes and oceans as algae populations explode in nutrient-rich water. From the air, the algae appear to be the primary players in the ecological drama unfolding below. But those single-celled organisms we credit for influencing the aquatic environment at the...
In a recent study about coronavirus, experts from Cambridge University were able to map the genetic history of COVID-19 from December, when the spread was first recorded, to March, discovering that the virus has three distinct strains, all of which are closely related to each other. The analysis showed three different strains of coronavirus. Three...
Key Points Question Could administration of convalescent plasma transfusion be beneficial in the treatment of critically ill patients with coronavirus disease 2019 (COVID-19)? Findings In this uncontrolled case series of 5 critically ill patients with COVID-19 and acute respiratory distress syndrome (ARDS), administration of convalescent plasma containing neutralizing antibody was followed by an improvement in...
A Scripps Research study reveals a likely site of vulnerability on the SARS-CoV-2 virus. SCRIPPS RESEARCH INSTITUTE LA JOLLA, CA — An antibody recovered from a survivor of the SARS epidemic in the early 2000s has revealed a potential vulnerability of the new coronavirus at the root of COVID-19, according to a study from scientists...
by Melissa Healy, Los Angeles Times For 10 patients severely ill with the new coronavirus, a single dose of antibodies drawn from the blood of people who had recovered from COVID-19 appeared to save lives, shorten the duration of symptoms, improve oxygen levels and speed up viral clearance, newly published research reports. The preliminary findings...
By Rich Haridy Up to 25 percent of people infected with COVID-19 may present no symptoms, yet still transmit the disease, says Robert Redfield, director of the US Centers for Disease Control and Prevention (CDC). The comment comes alongside a new report published by the CDC tracking transmission clusters that suggests infected individuals may be...
By shuffling DNA in and out of one gene, syphilis stays a step ahead of the immune system to resist eradication. The bacterium that causes syphilis, Treponema pallidum, likely uses a single gene to escape the immune system, new research from UW Medicine in Seattle suggests. The finding may help explain how syphilis can hide...
Based on the study from Korea’s Centers for Disease Control and Prevention, the once infected and now cured of the coronavirus still have a chance to reactivate within their body. This happens to be the case for some individuals who are thought to be cured or immune from the disease after winning their fight against...
AMERICAN THORACIC SOCIETY In a new study, researchers found that half of the patients they treated for mild COVID-19 infection still had coronavirus for up to eight days after symptoms disappeared. The research letter was published online in the American Thoracic Society’s American Journal of Respiratory and Critical Care Medicine. In “Time Kinetics of Viral...
Existing vaporized hydrogen peroxide methods can decontaminate N95 face masks for reuse, confirm research and clinical teams. Health care providers are facing a critical shortage of N95 face masks that block the coronavirus. The process uses specialized equipment to aerosolize hydrogen peroxide, which permeates the layers of the mask to kill germs, including viruses, without...
