Airflow inside car may be Covid transmission risk: Study
The simulations showed that opening windows -- the more windows the better -- created airflow patterns that dramatically reduced the concentration of airborne particles exchanged between a driver and a single passenger.
The researchers found that blasting the car's ventilation system didn't circulate air nearly as well as a few open windows.
Pixxel plans to have its satellite constellation up in sky by 2022

Kidney disease leading risk factor for Covid hospitalisation: Study
However, the study suggests that the physiological stress caused by an excessive inflammatory response to Covid-19 infection could destabilise organs already weakened by chronic disease, or that organ injury from the virus could act as a "second-hit" to these organs.
Can blood-sugar drug metformin cut Covid-19 death risk?
"Seeing a bigger association with protection in women over men may point towards inflammation reduction as a key way that metformin reduces risk from Covid-19," said principal investigator Carolyn Bramante, Assistant Professor at the University of Minnesota Medical School in the US.
NewSpace India not to transfer ISRO's space tech to individuals
According to the draft policy, cost of technology development will be done on marginal costing basis-expenses that would not be incurred had not the technology development been undertaken. It is New Space India's mandate to actively pursue technology transfer so that benefits of the space programme are transferred to Indian industries, both public and private sector.
Climate change already disaster to health: Lancet study
According to the researchers, globally, people worked 302 billion hours less in 2019 because of scorching temperatures - 103 billion more hours than were lost in 2000. Rising temperatures have also triggered more wildfires, which poses another set of health threat.
No risk of nanoparticles in sunscreen sprays: Study
The findings published in the journal Aerosol Science and Engineering are a result of experiments conducted using three aerosol sunscreens commonly found on store shelves. The research team simulated the application process for someone using the recommended amount of sunscreen and analyzed the released aerosols.
