This antiviral drug blocks Covid virus within 24 hrs: Study
In the study, the research team repurposed MK-4482/EIDD-2801 against SARS-CoV-2 and used a ferret model to test the effect of the drug on halting virus spread. The team believe ferrets are a relevant transmission model because they readily spread SARS-CoV-2, but mostly do not develop severe disease, which closely resembles SARS-CoV-2 spread in young adults.
Japan's Hayabusa2 capsule bringing asteroid sample to Earth
It was confirmed from telemetry and Doppler data that Hayabusa2 re-entry capsule separated from the Hayabusa2 spacecraft as planned at 14.35 local time on Saturday, the Japan Aerospace Exploration Agency (JAXA)) said.
Researchers develop sensor to detect fatty liver disease
It takes about 10 minutes to obtain the results, but the researchers are now working on improving the signal-to-noise ratio of the detector, which could help to reduce the amount of time it takes. The current version of the sensor can scan to a depth of about six millimetres below the skin, which is enough to monitor the mouse liver or human skeletal muscle.
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
The constellation of Pixxel's 30 satellites will be called Firefly, he added. The company has signed up with NewSpace India Ltd to launch its first satellite using Indian Space Research Organisation's (ISRO) Polar Satellite Launch Vehicle (PSLV) rocket in early 2021.
ISRO's PSLV rocket to launch Pixxel's earth imaging satellite
According to the Bengaluru-based Pixxel, it is building a constellation of earth imaging small satellites to provide an entirely new kind of dataset that today's satellites aren't capable of. The planned constellation will provide global coverage every 24 hours.
Eminent India-born US scientist Kapany passes away
He as a great philanthropist and the founder of the Sikh Foundation who introduced various aspects and facets of Sikhism globally through several books, art works and exhibitions, besides working tirelessly for preserving Sikh architectural heritage.
NASA picks 4 companies to collect lunar resources
The four companies selected by NASA are Colorado-based Lunar Outpost of Golden; Masten Space Systems of Mojave, California; ispace Europe of Luxembourg; and ispace Japan of Tokyo. Overall, the new NASA contracts with these companies totals $25,001, the US space agency said on Thursday.
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.
