NewsHigh-throughput modular click chemistry synthesis of catechol derivatives to target Covid protease
Researchers performed high-throughput synthesis of catechol derivatives from the bioactive catechol-terminal alkyne scaffold A4, by using modular click chemistry, in a bid to target the Covid virus’s 3C-like protease (3CLpro).

NewsCould a bout of COVID protect you from a severe case of flu?
More than 200 viruses can infect and cause disease in humans; most of us will be infected by several over the course of a lifetime. Does an encounter with one virus influence how your immune system responds to a different one?

NewsGenetic tracing at the Huanan Seafood market supports COVID animal origins
A study provides a list of the wildlife species present at the market from which SARS-CoV-2 most likely arose in late 2019, based on a new analysis of metatranscriptomic data released by the Chinese Center for Disease Control and Prevention (CDC).

NewsOrigami paper sensors could help early detection of infectious diseases in low-cost test
Researchers have developed an innovative new method for identifying biomarkers in wastewater using origami-paper sensors, enabling the tracking of infectious diseases using the camera in a mobile phone.
-
NewsLow-power laser can selectively detect coronavirus spike proteins in just five minutes
Researchers have demonstrated a method to detect the presence of viruses quickly, using only a small sample. The light-induced immunoassay coated with novel coronavirus spike proteins was highly sensitive even with weak light like a laser pointer.

NewsAntiviral-resistant variants of SARS-CoV-2 can emerge in immunocompromised people
Individuals with compromised immunity and persistent COVID-19 infections can harbor drug-resistant variants of the SARS-CoV-2 virus, which have the potential to spread to the general population.
-
NewsStudy sheds light on how virus-fighting cells develop during long Covid
A new long-term study into long COVID has investigated how a certain population of white blood cells, called memory T cells, are established and develop as part of the body’s defense to fight off the disease.

NewsUS COVID-19 rates show oscillating waves every six months
COVID-19 cases in the U.S. have shown unexpected oscillating waves every six months between the southern states and the northern states and, to a lesser degree, from east to west, according to new research.
-
NewsScientists discover dual roles of antibodies in COVID-19 infections
A new study has discovered an antibody that can both assist and block a virus. This particular antibody helps pre-Omicron variants of the virus infect cells while preventing the Omicron variant from doing the same.
-
NewsIt’s the unchanging parts of the Covid virus we also need to pay attention to, study suggests
A new study demonstrates the value of surveillance for public health initiatives, while identifying stable parts of the virus as potential candidates for small molecule drugs and other drug development.

NewsStudy uncovers the specialized immune cells that fight COVID-19
A team of researchers from Osaka University has pinpointed the B cells responsible for boosting COVID-19 immunity after vaccination.
-
NewsNew study provides insight to why Covid vaccines hit some harder than others
Scientists have highlighted factors that may explain why some people perceived more side effects from the SARS-CoV2 vaccine than others, including stress, exercise, and use of hormonal birth control.
-
NewsObesity may increase susceptibility to contracting COVID-19
Electronic health record data revealed that individuals with obesity were 34% more likely to become COVID positive after reported exposure than individuals without obesity.

NewsSevere COVID-19 can involve either exacerbated lung inflammation or high viral replication
Researchers report a study based on autopsies of 47 patients who died after being infected by the ancestral strain of SARS-CoV-2. The findings will support clinical decisions on the treatment of critical cases.
