Every time the coronavirus passes from person to person it picks up tiny changes to its genetic code, but scientists are starting to notice patterns in how the virus is mutating. For more than three months the patient struggled against Covid-19. His immune system was already in a bad way when he caught the [...]
A filter made from polymer nanothreads blew three kinds of commercial masks out of the water by capturing 99.9% of coronavirus aerosols in an experiment. "Our work is the first study to use coronavirus aerosols for evaluating filtration efficiency of face masks and air filters," said corresponding author Yun Shen, a UC Riverside assistant [...]
MSU researcher is studying, raising awareness about the role of sex in the efficacy of vaccines that make use of nanomedicine If there’s one take-home message for the general public about the coronavirus vaccines approved in the U.S., it’s that they are remarkably effective. MSU Assistant Professor Morteza Mahmoudi But Michigan State University’s Morteza [...]
Earlier this month, the World Health Organisation (WHO) acknowledged that the Coronavirus can also be airborne. After denying for more than a year, the WHO finally updated the mode of Covid-19 transmission and said that the disease can be an airborne threat. It said, “the virus can also spread in poorly ventilated and/or crowded [...]
A collaboration of Australian and US scientists has developed a potential antiviral therapy to directly target and treat COVID-19. Researchers from the Menzies Health Institute Queensland (MHIQ) at Griffith University and US research institute City of Hope have developed an RNA therapy that genetically targets SARS-CoV-2 and prevents it from replicating. Co-lead researcher Professor [...]
What happens if you mix COVID-19 vaccines, receiving a first dose of one jab and a second dose of a different inoculation? Scientists want to know. Why? Because mixing doses might give governments more flexibility to stretch available vaccine supplies across populations, ensuring more people get vaccinated and doses won’t go to waste. There’s also speculation [...]
CAR-T therapy can cure terminally ill cancer patients but it is prohibitively expensive, costing hundreds of thousands of dollars. Leveraging recent advances in chip technology scientists can create and mass produce small machines to re-engineer the immune system. But the scientific community needs public-private partnerships to ensure this medical breakthrough becomes accessible to everyone. [...]
Breakthrough infections are exceedingly rare. But by tracking them, researchers can uncover viral variants that manage to dodge the immune response. Tens of millions of people in the United States have now been fully vaccinated against covid-19. These people are seeing friends, eating out, and—in rare cases—getting infected. But we shouldn’t panic: these kinds [...]
Researchers from Hong Kong Baptist University (HKBU), in collaboration with Cornell University, have developed a novel targeted therapy for triple-negative breast cancer (TNBC) that uses a specially-designed nano-carrier to deliver the Chinese medicine compound gambogic acid (GA). The invention enhances the anti-cancer effect of GA and reduces its damage to off-target organs. The invention [...]
Modern vaccines such as those against Sars-CoV-2 use tiny lipid spheres to transport genetic information into cells and let the body build up an immune defense against the virus. A team of scientists from Erlangen, Dresden, and London has now developed a completely new method to very efficiently deliver not only genes but also [...]
