Covid-19: is it safe to play the trumpet and other wind instruments?

Aerosol generated by playing woodwind and brass instruments is less than that produced when vocalising (speaking and singing) and is no different than a person breathing, new research has found. The findings could be crucial to developing a roadmap for lifting Covid-19 restrictions in the performing arts, which have been significantly restricted since the start of the pandemic.

Covid-19: Why faster air exchange in buildings is not always beneficial

Vigorous and rapid air exchanges might not always be a good thing when it comes to addressing levels of coronavirus particles in a multiroom building, according to a new modeling study. The study suggests that, in a multiroom building, rapid air exchanges can spread the virus rapidly from the source room into other rooms at high concentrations. Particle levels spike in adjacent rooms within 30…

Experts: Covid-19 prevention efforts should focus on airborne transmission

Any future attempts to reduce the spread of Covid-19 should be focused on tackling close airborne transmission of the virus which is considered to be the primary route for its circulation, according to experts. Respiratory experts argue that it is now clear that SARS-CoV-2 is most likely to transmit between people at close range through inhalation rather than through contact with surfaces or…

A 'fake handshake' to trick the coronavirus

Scientists have developed peptides that fit snugly into a groove on the SARS-CoV-2 Spike protein that it would normally use to access a host cell. These protein fragments effectively trick the virus into “shaking hands” with a replica rather than with the actual protein on a cell’s surface that lets the virus in. revious research has determined that the novel coronavirus binds to a receptor…

Laser light shows X-ray holographic images of viruses

Holography, like photography, is a way to record the world around us. Both use light to make recordings, but instead of two-dimensional photos, holograms reproduce three-dimensional shapes.
