Nanomedicines may offer clinicians a way to deliver precise, targeted therapy directly to tumors without damaging surrounding tissue. Yet, progress in the development of new drugs that treat cancer at the nanoparticle level has been frustratingly slow. Good results in animal models haven’t necessarily translated to clinical success in humans, in part because of [...]
Cambridge researchers have discovered how T cells—an important component of our immune system—are able keep on killing as they hunt down and kill cancer cells, repeatedly reloading their toxic weapons. Cytotoxic T cells are specialist white blood cells that are trained by our immune system to recognize and eliminate threats—including tumor cells and [...]
Sunday, October 3, set records for the most COVID-19 deaths in Russia on a single day. Only 29% of people in Russia are vaccinated, despite the country being the first to approve a vaccine. The vast majority of hospitalized COVID-19 patients in Russia are unvaccinated. On Sunday, October 3, Russia reported its highest number [...]
New research from the University of Technology Sydney (UTS) has found that pathogens that form biofilms can evolve to survive nanosilver treatment. The study is the first to demonstrate that long-term nanosilver treatment can increase the risk of recurrent infections. The research is published in the Journal of Nanobiotechnology. Nanosilver is a potent antimicrobial [...]
New variants of SARS-CoV-2 are more virulent and transmissible than the original variant of the virus. Health experts associate these variants of concern (VOCs) with increased risk of hospitalization, intensive care unit (ICU) admission, and death. Vaccination reduces the risks of severe disease and death even with the VOCs. However, even with increased vaccination, [...]
Freeze-dried genetic circuits could reveal the presence of SARS-CoV-2, Ebola, MRSA, and more. Masks and testing have been key to the COVID-19 pandemic response—and now devices that combine the two may be on the way. Harvard University and Massachusetts Institute of Technology researchers used synthetic biology to create a face mask that accurately detects [...]
Hundreds of neuroscientists built a ‘parts list’ of the motor cortex, laying groundwork to map the whole brain and better understand brain diseases. Before you read any further, bring your hand to your forehead. It probably didn’t feel like much, but that simple kind of motion required the concerted effort of millions of different [...]
An international team, led by Swinburne University of Technology and Australian National University (ANU), have made a breakthrough discovery that could potentially lead to faster, more accurate molecular or virus tests, including for COVID-19. The researchers were inspired by how light is concentrated in butterfly wings and have discovered a new way to concentrate light on a [...]
New mutations of COVID-19, such as the Delta strain, are "getting better" at transmitting through the air, a study has found. People infected with a later variant of COVID-19 put 43 to 100 times more virus into the air when breathing than those who were infected with the original strains of the virus, according to the University [...]
Merck will seek U.S. approval for pill as soon as possible If approved, would be 1st oral antiviral COVID-19 drug Merck shares rally, some vaccine makers fall U.S. government to buy 1.7 mln courses at $700 each Oct 1 (Reuters) - An experimental antiviral pill developed by Merck & Co (MRK.N) could halve the chances of [...]
