NewsCo-infection with ‘superbug’ bacteria increases SARS-CoV-2 replication up to 15 times
New research has revealed that IsdA, a protein found in all strains of Staph A., boosts SARS-CoV-2 replication by 10- to 15-fold.

NewsResearchers discover previously unknown Achilles heel of Covid virus
Scientists concluded that only a survey of neutralising antibodies can inform us about protection against new Covid infections, then disovered a previously unknown weak point of the virus when analysing specific characteristics of those antibodies.

NewsA water-dampened wipe removes Covid virus from indoor surfaces
Wiping indoor surfaces with a water-dampened wipe removes greater than 80% of Covid virus, yet pre-wetting the surface with water or detergent doesn’t make much difference, a new EPA study finds.

NewsInexpensive way to produce anti-Covid nanobodies cuts down on the llamas
Researchers have come up with a less expensive way to isolate and identify nanobodies that target various parts of the SARS-CoV-2 spike protein and are currently derived from llamas.

NewsCommon cold gives children immunity against COVID-19
Researchers have identified memory T cells in children’s blood samples taken before the pandemic that react to cells infected with SARS-CoV-2, the virus that causes COVID-19.

NewsNaturally occurring amino acid could point way towards Covid cure
A promising treatment strategy that could pave the way for a Covid-19 cure is targeting angiotensin-converting enzyme 2 (ACE2), a receptor found on the cell membrane that allows entry of the virus into the cell due to its high affinity for SARS-CoV-2’s spike protein.

NewsUCF researchers receive patent for COVID-killing nano-coating
A team of researchers have been awarded a patent for their nanomaterial-based disinfectant that can not only destroy the COVID-19 virus, but combat the spread of Zika virus, SARS, parainfluenza, rhinovirus and vesicular stomatitis.

NewsExtracts from two wild plants inhibit COVID-19 virus, study finds
Two common wild plants contain extracts that inhibit the ability of the virus that causes COVID-19 to infect living cells, the first major screening of botanical extracts to search for potency against the virus has revealed.

NewsTwo Chinese anti-SARS-CoV-2 drugs conditionally approved for marketing
Two innovative Chinese oral anti-SARS-CoV-2 drugs, Xiannuoxin (simnotrelvir/ritonavir) and VV116 (deuremidevir hydrobromide), were conditionally approved for marketing by China’s National Medical Products Administration (NMPA) in late January after urgent review and approval under the Special Examination and Approval of Drugs Policy.

NewsSmall molecules lock Covid spike proteins in harmless closed configuration
Researchers report that they have discovered small molecules that successfully target segments of the Covid spike protein that mutate less, locking the protein in a harmless configuration.

NewsWhite-tailed deer carry SARS-CoV-2 variants that are extinct in humans
Researchers have found white-tailed deer – the most abundant large mammal in North America – are harboring SARS-CoV-2 variants that were once widely circulated, but are no longer found in humans.

NewsChange in genetics of SARS-CoV-2 evolved to counter weakness caused by the virus’s initial mutation
Researchers at Johns Hopkins Medicine say their new studies suggest that the first pandemic-accelerating mutation in the SARS-CoV-2 virus, which causes COVID-19, evolved as a way to correct vulnerabilities caused by the mutation that started the SARS-CoV-2 pandemic.
