-
NewsGermicidal UV lights could be producing indoor air pollutants, study finds
While useful for killing pathogens including SARS-CoV-2, the lights may cause unwanted chemical reactions and should be used with ventilation, researchers say.
-
NewsAlert immune system in respiratory tract protects children from severe Covid
Scientists have discovered that the immune system in the upper respiratory tract is much more alert and active in children before infection than in adults and is therefore better equipped to fight the virus.
-
NewsStudy finds increased risk of Guillain-Barré after COVID-19 infection
Having a COVID-19 infection is associated with an increased risk of developing the rare disorder called Guillain-Barré syndrome within the next six weeks.
-
NewsSingle vaccine protects against three deadly strains of coronavirus

-
NewsScientists develop deep learning-based biosensing platform to count viral particles better
The innovative platform combines a Gires-Tournois biosensor with deep learning to achieve a high bioparticle detection accuracy even at low concentrations.
-
NewsViral persistence and serotonin reduction can cause long COVID symptoms
Components of the SARS-CoV-2 virus remain in the gut of some long COVID patients, causing persistent inflammation, vagus nerve dysfunction, and neurological symptoms.
-
News Targeting a coronavirus ion channel could yield new Covid-19 drugs
Chemists discover the structures of open and closed states of the channel, which could help the development of antiviral drugs to reduce inflammation.
-
NewsStudy reveals how young children’s immune systems tame SARS-CoV-2
A study of infants and young children found those who acquired SARS-CoV-2 had a strong, sustained antibody response to the virus and high levels of inflammatory proteins in the nose but not in the blood.
-
NewsCoronavirus vaccination reveals that body builds immune memory in organs
A study of the mRNA coronavirus vaccines reveals that the human body builds local immune memory in various organs. The immune memory cells are more numerous in the organs than in the blood and have enhanced antiviral defense functions.
