NewsStudy finds evidence of resistance to COVID-19 drugs
Resistance to Paxlovid is already evident among viral SARS-CoV-2 variants currently circulating globally, indicating that this stand-alone drug known as a protease inhibitor could soon become less effective in treating COVID-19 infections, a new study suggests.

NewsTeam designs molecule to disrupt SARS-CoV-2 infection mechanism
A team of scientists led by the Department of Energy’s Oak Ridge National Laboratory has designed a molecule that disrupts the infection mechanism of the SARS-CoV-2 coronavirus and could be used to develop new treatments for COVID-19 and other viral diseases.

NewsNasal spray protects against coronavirus infection- including recent immune-evasive variants
Researchers have developed a molecule that is, when administered nasally, extremely effective in preventing the disease caused by all known variants of the SARS-CoV-2 virus.

NewsNext epidemic could be spotted early in wastewater, say scientists
Researchers analysing wastewater say that routine monitoring at sewage treatment works could provide a powerful early warning system for the next flu or norovirus epidemic, alerting hospitals to prepare and providing public health agencies with vital health information.

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.

NewsStudy shows New York City rats carry SARS-CoV-2
Wild rats in the New York City municipal sewer systems and elsewhere in the city have been exposed to SARS-CoV-, a new study has revealed.

CareersThe Kulkarni Lab
The Kulkarni Lab works to determine how locally derived complement proteins in the lung can be harnessed to reduce the burden of end-stage lung disease.
-
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.

NewsSifting through sewage can forecast COVID-19 infections 5 days in advance
A new mathematical model uses wastewater samples to effectively forecast the number of clinical COVID-19 cases in a community five days in advance.

NewsCellular evidence reveals why men are at higher risk from COVID-19
Researchers from Osaka University provide cellular evidence for the observed differences between the response to COVID-19 infection in male and female patients.

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.

NewsVirologists call for ‘rational discourse’ on gain of function research
The study of viruses is under renewed scrutiny, say more than 150 experts in a commentary whose authors call on policymakers to recognize the need for more rational discourse around the future of virology, ahead of a meeting of the National Science Advisory Board for Biosecurity .
