The coronavirus pandemic continues to remain elusive, with new information coming in every day about the virus, and ways to prevent it.

Masks, face shields, and gloves have become the new normal, and people are playing with different ideas to protect themselves in a world where isolation is difficult, if not impossible.

According to a simulation by a Japanese supercomputer, plastic face shields are totally ineffective at trapping aerosols, making it an inefficient tool against COVID-19.

Simulation of aerosol activity

The world’s fastest supercomputer, Fugaku undertook a simulation whereby it was found that almost 100 per cent of airborne droplets smaller than 5 micrometres were able to escape through plastic visors which have become a common sight now.

One millionth of a metre constitutes one micrometre. According to a government-backed research institute, about half of larger droplets over 50 micrometers were also able to escape into the air.

Besides hand washing and sanitisation, aerosol transmission and ventilation are important factors in the transmission of coronavirus.

Face visors have become common as global economies reopen, with shops across all sectors reopening.

Makoto Tsubokura, team leader at Riken’s centre for computational science, said the simulation combined air flow with the reproduction of tens of thousand of droplets of different sizes, from under 1 micrometre to several hundred micrometres.

Not an alternative to masks

To ascertain the role of face shield’s protection against COVID-19, the simulation took into account air flow and production of thousands of droplets of varying sizes.&nbsp;

Makoto Tsubokura, the team head at Riken’s centre for computational science told the Guardian that face shields should not be seen as an alternative to masks, and further added that the effectiveness of visors is lesser compared to face masks.

“This is especially true for small droplets of less than 20 micrometres,” he told The Guardian.

Small particles were able to escape through the gap between the face shield and the face.

Earlier, Fugaku had found that face masks made out of non-woven fabric are more effective than cotton and polyester masks.

Face shields ineffective against COVID-19, rules world's fastest supercomputer

SpaceX is poised to launch an unmanned cargo ship toward the International Space Station Monday, including a super-computer that could direct astronauts on future deep-space missions.

The liftoff of the Falcon 9 rocket, carrying the Dragon cargo ship, is planned for 12:31 pm (1631 GMT) from Cape Canaveral, Florida.

The weather forecast is 70 per cent favorable for launch.

The mission is the 12th official trip for SpaceX, which has a $1.6 billion contract with NASA to supply the astronauts living in orbit over 20 such back-and-forth journeys.

About 10 minutes after launch, the rocket will attempt to make a controlled landing back on solid ground at Cape Canaveral, as part of SpaceX&#39;s ongoing effort to reuse rocket components after each take-off.

If Monday&#39;s launch is delayed for any reason, the next attempt would have to wait until next week, due to a spacewalk planned for Thursday by Russian cosmonauts, who will deploy a series of satellites from the orbiting outpost.

The Dragon is packed with 2,900 kilograms of supplies, including a sophisticated super-computer made by Hewlett Packard Enterprise (HPE), called The Spaceborne Computer.

The goal is to test the computer for one year to see if it can operate in the harsh conditions of space, about the same amount of time as it would take for astronauts to arrive at Mars.

As astronauts travel millions of miles away, communications will become increasingly delayed. Messages from Mars to Earth would be delayed from between four minutes to 24 minutes one-way, depending on the distance between the planets, according to the European Space Agency.

&quot;Such a long communication lag would make any on-the-ground exploration challenging and potentially dangerous if astronauts are met with any mission critical scenarios that they&#39;re not able to solve themselves,&quot; said HPE senior vice president Alain Andreoli in a statement.

The new super-computer aims to provide &quot;sophisticated onboard computing resources that are capable of extended periods of uptime,&quot; he added, describing the year-long effort as &quot;the first step in that direction.&quot;

Another experiment on board is designed to help scientists study Parkinson&#39;s disease in greater detail in the hopes of finding better treatments for this degenerative disease.&nbsp;

Un-impeded by gravity, protein crystals can grow larger in space, and scientists hope to use this environment to help them understand an important protein in Parkinson&rsquo;s disease, known as Leucine-rich repeat kinase 2 (LRRK2).

Until now, this protein has been difficult to study in Earth, according to researchers at the Michael J. Fox Foundation, which developed the research project.

Other experiments on board include a stem cell investigation for growing new lung tissue, and equipment for growing vegetables in space.
