NewsScientists craft enhanced viral structure in VLP vaccines through polymer restructuring
Researchers reported a viromimetic polymer nanoparticle vaccine (VPNVax), crafted by rearranging the RBD proteins of the coronavirus and modifying them onto the surface of pre-assembled polyethylene glycol-polylactic acid polymer nanoparticles.

NewsUptake of HIV prevention medication doubles with mix of digital health interventions
A combination of interventions of one-on-one telehealth coaching, peer support forums, and automated text messages more than doubled the use of the HIV prevention strategy, called PrEP, among younger, at-risk Americans.

NewsStudy finds high number of persistent COVID-19 infections in the general population
A new study has found that a high proportion of SARS-CoV-2 infections in the general population lead to persistent infections lasting a month or more, with some of these showing a high number of mutations.

NewsBat mating swarms may be the key to solving the next pandemic
The evolution of viral tolerance in Myotis bats may help scientists prevent future pandemics, say researchers.

NewsFatty acid produced by gut bacteria directly influences fat metabolism in animals
Researchers investigating gut bacteria that produce fatty acids with a special chemical structure, known as a cyclopropane ring, showed that these can be converted into signals that turn on fat desaturation in the nematode C. elegans.

NewsStudy identifies surge in antibiotic-resistant typhoid
Researchers used whole genome sequencing to identify that S Typhi isolates with mutations evolved locally from the endemic S Typhi population in Blantyre, Malawi, and were not the result of importations from other countries.

NewsScientists reveal what makes ‘bad’ bacteria life-threatening
Researchers have discovered that a mutation allows some E. coli bacteria to cause severe disease in people while other bacteria are harmless, a finding that could help to combat antibiotic resistance.

NewsPlasma device is giant step forward to help treat chronic wounds that affect millions
A team of international scientists has developed a more effective treatment for chronic wounds that does not involve antibiotics or silver-based dressings, but an ionized gas called plasma. Source: University of South Australia The plasma activates oxygen and nitrogen molecules to treat wounds effectively. The treatment involves ...
