India Is Trying To Build The World's Biggest Facial Recognition System

The child labor activist, who works for Indian NGO Bachpan Bachao Andolan, had launched a pilot program 15 months prior to match a police database containing photos of all of India's missing children with another one comprising shots of all the minors living in the country's child care institutions.
India is unable to match 10,561 missing children with those living in institutions. They are currently in the process of being reunited with their families. Most of them were victims of trafficking, forced to work in the fields, in garment factories or in brothels.
This momentous undertaking was made possible by facial recognition technology provided by New Delhi's police.

India-UK Collaboration Creates a Hand-Washing Robot

Collaboration between researchers from the UK and India has resulted in a new robot which encourages children to wash their hands.
The robot, named Pepe, was recently used by pupils at a primary school in Kerala as a fresh approach to hygiene.
Pepe was mounted to the wall above a hand washing station at the Wayanad Government Primary School, which has around 100 pupils aged between five and 10.
A small video screen mounted behind Pepe's green plastic exterior acted as a mouth, allowing researchers to tele-operate the robot to speak to the pupils and draw their attention to a poster outlining the steps of effective handwashing.

NASA astronauts Christina Koch and Jessica Meir in all-women spacewalk

NASA astronauts Christina Koch and Jessica Meir have made history by completing the first ever all-female spacewalk.
They spent seven hours outside the International Space Station (ISS) replacing a failed power control unit.
Ms Koch had already carried out four spacewalks but it was the first such mission for Ms Meir, who became the 15th woman to walk in space, Nasa said.
Ms Koch, an electrical engineer, and Ms Meir have doctorate in marine biology. They made their way to a location called the Port 6 truss structure to replace the battery charge-discharge unit (BCDU).

IIT Kharagpur Graduate Develops Device To Curb Air Pollution

An IIT Kharagpur graduate has invented a device called "PM 2.5" which he claimed when fitted near the silencer pipe in vehicles will curb air pollution.
Debayan Saha, a mechanical engineering graduate from IIT Kharagpur, who has invented the device claims that one car fitted with the device can neutralise the pollution emitted from 10 cars in its vicinity.
The technology uses a combination of electric energy and wave energy to influence the pollutants like PM 2.5 such that they act like magnet attracting other particulate pollutants from the ambient atmosphere to get attached to it. As they grow bigger in size they become heavy and fall off safely on the ground like soil.
Saha was also a research fellow at AIIMS who worked on air pollution.

ISRO'S Space Shuttle-Like Reusable Launch Vehicle Will Attempt Its First Landing In Karnataka

The Indian Space Research Organisation (ISRO) is finally following in the footsteps of NASA and SpaceX by developing a space program for Reusable Launch Vehicles (RLV) which it has been testing since 2016.
The RLV program aims to cut down on launch costs by, well, reusing the spacecraft. ISRO's current project appears to be using a hybrid design that sits somewhere between NASA's now-shuttered Space Shuttle program and SpaceX's reusable rockets.
India's RLV includes a Space Shuttle-like craft that could feature an air-breathing ramjet engine.
This craft will take a payload to space and then glide back to Earth, landing like a normal aircraft, much like the Space Shuttle.
The rocket that will take this shuttle to orbit will return to Earth much like Musk's Falcon 9 rockets. It will return under its own power and make a landing on a floating platform out at sea.
So far, the RLV shuttle has been tested over water. Now, it will be tested over land and make an attempt at an actual landing.

NASA unveils two new spacesuit prototypes for mission to colonize the moon by 2024

NASA showed off two new spacesuits tailored for future moonwalking astronauts, signalling development of a crucial component to the space agency's accelerated drive to return to the moon by 2024.
Two NASA engineers strutted on a stage inside the agency's Washington, D.C. headquarters, donning the new spacesuits, modelling and doing squats and crunches in front of a crowd of students and reporters to reveal what the first zero-gravity space-wear under NASA's Artemis moon program would look like.

IIT Guwahati To Organise International Symposium On Advances In Sustainable Polymerse

Indian Institute of Technology Guwahati in collaboration with Kyoto Institute of Technology is organizing an International Symposium on Advances in Sustainable Polymers (ASP-19) from October 14 to 18, 2019 at Kyoto Institute of Technology, Matsugasaki, Sakyo-ku, Kyoto, Japan.
ASP-19 is the fifth international symposium of the ASP series following ASP-17 (Guwahati, India), ASP-16 (Kyoto, Japan), ASP-15 (Guwahati, India), and ASP-14 (Guwahati, India).
ASP-19 will also host the following three bilateral symposia as part of the symposium:

Industrial Forum - Biobased Materials Developed by World-wide Industries
Second India-Nepal-Japan Trilateral Joint Symposium
IITG-KIT Joint Symposium
