A new simulation from the Fugaku supercomputer in Japan demonstrates how the seating arrangement can make a difference to how easily the coronavirus is transmitted to dining companions at the same table. Humidity seems to make a difference in transmission.

COVID-19 Data Reveal That Urban Density Is Not the Enemy
A new report in the Journal of the American Planning Association concludes that density doesn’t make a city sick; crowding and connectivity do. It’s important to disentangle those concepts.
Asymptomatic People Have as Much Coronavirus as Symptomatic People
New research has found that people with a SARS-CoV-2 infection who are asymptomatic carry just as much virus in their throats, lungs, and noses as those who have symptoms. Some experts believe that asymptomatic people have caused the virus to spread more readily in communities.
Researchers show children are silent spreaders of virus that causes COVID-19
Researchers have found the viral load in infected children to be very high, especially in the first 2 days of infection. We know that transmissibility or risk of contagion is greater with a high viral load.
How likely are you to be infected by the coronavirus on a flight?
Is it safe to fly with the coronavirus still circulating? That depends partly on where you are. But while hard evidence is scarce, it appears the risk of being infected with covid-19 during a flight is relatively low.
Singing 'no riskier than talking' for virus spread
Singing does not produce substantially more respiratory particles than speaking at a similar volume, a study suggests. But it all depends on how loud a person is, according to the initial findings which are yet to be peer reviewed. The project, called Perform, looked at the amount of aerosols and droplets generated by performers.
Some People Get Covid-19 and Never Feel a Thing: Why?
Scientists are studying a phenomenon called "disease tolerance." Understanding it in humans, if it exists, could revolutionize medicine. According to various estimates between 20 and 45 percent of people who get Covid-19, and possibly more – sail through the infection without realizing they had it.
Community and Close Contact Exposures Associated with COVID-19 Among Symptomatic Adults
Adults with positive SARS-CoV-2 test results were approximately twice as likely to have reported dining at a restaurant than were those with negative SARS-CoV-2 test results.
If the coronavirus is really airborne, we might be fighting it the wrong way
Whether the virus is airborne isn’t simply a scientific question. If it is, it could mean that in places where the virus has not been properly contained (e.g., the US), the economy needs to be reopened more slowly, under tighter regulations that reinforce current health practices as well as introducing improved ones.
COVID-19 risk was highest in window seats in Qantas economy class
Passengers sat in window seats in the middle of an economy class cabin on a Qantas Airways flight in March were most at risk from contracting coronavirus, according to research by Australian scientists into that particular trip.
