NewsOmicron subvariant BA.5 efficiently infects lung cells
Over the course of evolution of Omicron subvariants, viruses may arise that regain the ability to effectively spread in the lung and cause severe illness in risk patients and people with insufficient immunity, a new study suggests.

NewsHigh-res map of the human placenta reveals COVID virus hideouts
Researchers have developed a high-resolution map of the human placenta visualizing an array of different immune microenvironments in healthy placentas from uninfected pregnancies, and those from pregnancies affected by COVID infections.

NewsPurecap technique opens doors to more effective mRNA vaccines
Researchers have developed a method to produce highly active mRNA vaccines at high purity using a unique cap to easily separate the desired capped mRNA.

NewsFrequent use of antibiotics linked to severe Covid outcomes
Frequent and diverse use of antibiotics may be associated with developing more severe outcomes after a COVID-19 infection, including death, a new study has shown.
-
NewsScientists develop all-species Covid test
In an advance that will help scientists track coronavirus variants in wild and domesticated animals, researchers report they can now detect exposure to the SARS-CoV-2 virus in any animal species.

NewsEngineered lung cells light up when Covid sparks immune response
Scientists have engineered lab-grown lung epithelial cells to light up red in colour once they launch an immune response, creating a tool that can be used to screen for drugs that can help treat COVID-19 and other emerging infections.

NewsResearchers develop adhesive bandage that can detect COVID-19 antibodies
Researchers at NYU Abu Dhabi have developed a new rapid testing method for COVID-19 – an adhesive bandage that relies on gold nanoparticles to quickly detect the immune antibodies in the bloodstream. These antibodies, named IgM and IgG, are naturally produced as a result of SARS-CoV-2 infection, ...

NewsNewer Covid strains are less capable of surviving in the air
Scientists investigating why airborne viruses lose their infectivity have revealed how cleaner air kills the virus significantly quicker and why opening a window may be more important than originally thought.
