NewsResearchers reveal how the SARS-CoV-2 virus acquires its spherical shape
Researchers report that when the M protein, which is adjacent to the spike protein on SARS-CoV-2, gets lodged in the membrane, it coaxes the membrane to curve by locally reducing the membrane thickness.

NewsVaping can increase susceptibility to infection by SARS-CoV-2
Vapers are susceptible to infection by SARS-CoV-2, the virus that spreads COVID-19 and continues to infect people around the world, a new study has found.

NewsBCG mechanism extends protection to beat influenza A
A new study uncovered a previously unknown mechanism that extends the BCG vaccine’s shield to combat influenza A virus—the most prevalent flu strain.

NewsFusion protein reveals a conservative antigenic domain across herpesviruses
A new study proposes that the gB DII domain within the herpesvirus family constitutes a broadly conserved neutralizing epitope structural domain.

News‘Dynamic duo’ defences in bacteria ward off viral threats
Scientists have discovered that bacteria can pair up their defence systems to create a formidable force, greater than the sum of its parts, to fight off attack from phage viruses.

NewsStudy examines medical mystery of child hepatitis outbreak
A study into an unexpected wave of severe hepatitis cases in 2022 supports the theory that it was caused by an infection of different viruses at the same time, but also reveals cases were higher and more severe than initially thought.

NewsStudy of usefulness of lockdowns during epidemics identifies alternate solution
Researchers found that small nonpharmaceutical interventions can tip the optimal response between very different approaches to slowing viral spread and identified an alternate approach that has previously not been recognized as effective.

NewsLong-acting HIV treatment demonstrates efficacy in people with challenges taking daily medicine as prescribed
Long-acting antiretroviral therapy (ART) with cabotegravir and rilpivirine was superior in suppressing HIV replication compared to daily oral ART in people who had been unable to maintain viral suppression through an oral daily regimen, according to interim data from a randomized trial.

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.
