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 [...]
By early 2020, concern was mounting about a new, deadly coronavirus first detected in Wuhan, China. The World Health Organization had declared the coronavirus outbreak a global health emergency just days before. There had been more than 400 deaths and more than 20,000 cases, most of those in China. But the virus was spreading around [...]
As a COVID-19 and medical device researcher, I understand the importance of face masks to prevent the spread of the coronavirus. So I am intrigued that some mask manufacturers have begun adding graphene coatings to their face masks to inactivate the virus. Many viruses, fungi and bacteria are incapacitated by graphene in laboratory studies, [...]
Swansea University scientists have uncovered potentially dangerous chemical pollutants that are released from disposable face masks when submerged in water. The research reveals high levels of pollutants, including lead, antimony, and copper, within the silicon-based and plastic fibres of common disposable face masks. The work is supported by the Institute for Innovative Materials, Processing [...]
Bowel cancer survival rates could be improved if chemotherapy drugs were delivered via tiny nanoparticles to the diseased organs rather than oral treatment. That's the finding from Indian and Australian scientists who have undertaken the first study, using nanoparticles to target bowel cancer, the third most common cancer in the world and the second [...]
Pfizer CEO Albert Bourla says his company’s experimental COVID-19 treatment, a pill that can be taken at the first sign of the illness, could be available before the end of the year. Speaking on CNBC, Bourla said clinical trials are underway for the pill. If those go well and the Food and Drug Administration approves the drug, distribution [...]
At the University of Chicago, scientists have developed an absolutely innovative, promising treatment for COVID-19 in the form of nanoparticles with the ability to trap SARS-CoV-2 viruses inside the body and use the body’s own immune system to kill them. The “nanotraps” lure the virus by imitating the target cells infected by the virus. [...]
Australian researchers have identified neutralizing nanobodies that block the SARS-CoV-2 virus from entering cells in preclinical models. The discovery paves the way for further investigations into nanobody-based treatments for COVID-19. Published in PNAS, the research is part of a consortium-led effort, bringing together the expertise of Australian academic leaders in infectious diseases and antibody therapeutics at WEHI, [...]
