New research sheds light on how planetary systems are formed
Scientists say they have been able to measure details of the orbit of a planet 63 million light-years away. Data on its spin-orbit alignment could help astrophysicists understand more about how solar systems are formed.
* Kraus led a team of international scientists to measure the planet's spin-orbit alignment using the Very Large Telescope Interferometer (VLTI) in Chile.
* Scientists say it's the first time this has been done for a directly imaged planetary system.
* The spin-orbit alignment is the degree of alignment between the orbit of planets and their star's rotation axis.
* In our solar system, for example, the planets orbit on a plane in line with the equator of the sun and the same direction as the Sun rotates.
* Measuring Beta Pictoris b considered to be a 'wide separation planet', that is one that is positioned far from its star helps scientists understand how planetary systems are formed, particularly with regards to so-called 'Hot Jupiters' planets found very close to their star.

ICMR approves antigen kit that gives COVID-19 test results in 30 minutes
Indian Council of Medical Research (ICMR), the body leading the COVID-19 response in the country, has given its nod to a Korean company’s antigen-based coronavirus test kit that gives results in 30 minutes.
* The kits will allow faster diagnosis without laboratory examination Standard Q Covid-19 Ag detection kit is a rapid chromatographic immunoassay for qualitative detection of specific antigens to SARS-CoV-2.
* Standard Q COVID-19 Ag detection kit developed by Korean company-SD Biosensor is a rapid chromatographic immunoassay for the qualitative detection of specific antigens to SARS-CoV-2.

IIT-M researcher team develops high energy bio-oil
Indian Institute of Technology Madras (IIT-M) researchers have developed a simple microwave process to produce bio-fuel oils with high energy values from two waste products – agricultural waste such as rice straw and bagasse and discarded plastics.

* The project was funded by GAIL (India) Ltd.
* The research team led by Dr R. Vinu, Associate Professor, Department of Chemical Engineering and the other members were Dr Dadi Suriapparao and Banupriya Boruah.
* One of the common methods to produce bio-oil from biomass is ''pyrolysis'' or heat-induced breakdown of the biomass components into fuel components.

SpaceX launches 61 satellites
The private spaceflight company SpaceX launched 58 new Starlink satellites to join its mega-constellation of broadband internet transmitters.
* Three SkySat Earth-imaging satellites for Planet will launch as rideshare payloads on this mission.
* A SpaceX Falcon 9 rocket launched the satellites - the ninth batch in SpaceX's Starlink broadband network.

IIT Roorkee develops nano-coating system to senitise used masks and PPE kits
A research team from Indian Institute of Technology (IIT) Roorkee has developed a nano-coating system to sanitise used masks and on personal protective equipment (PPE) kits which can be used again.
* With the help of this nano-coating, used masks and PPE kits will be disinfected in 10 to 15 minutes and can be used again to contain the spread Coronavirus.
* This coating system is also effective in diseases such as Staphylococcus aureus and Escherichia coli.
