Purple Frog:
also known as Maveli frog or Pignose Frog.
It is relatively round in shape as compared to other flattened frogs.
For almost its entire life it lives in underground tunnels and comes out to surface for only a single day in a year to breed.
Distribution: They were thought to be limited to south of the Palghat Gap (a pass which is located between Nilgiri Hills to north and Anaimalai Hills to south) in Western Ghats, but are now known to be quite widely distributed in Western Ghats.
The frog should rightly be called ‘living fossil’ as it is believed that they have co-existed with dinosaurs almost 70 million years ago.
IUCN Red List: Their conservation status is endangered as per International Union for Conservation of Nature (IUCN).

NASA’s First Planetary Defense Technology Demonstration to Collide with Asteroid in 2022.
The Double Asteroid Redirection Test, or DART, is a spacecraft designed to determine whether an asteroid can be redirected with a high-speed collision.
SpaceX will launch the spacecraft toward an asteroid named Didymos about 4 million miles from Earth. It then will ram into the asteroid’s small moon at about 13,000 miles per hour.
DART would be NASA’s first mission to demonstrate what’s known as the kinetic impactor technique – striking the asteroid to shift its orbit – to defend against a potential future asteroid impact.

UPSC 2015 Prelims Question
National Innovation Foundation – India (NIF) is an autonomous body under the Department of Science and Technology (India), Government of India. It was set up in February 2000 at Ahmedabad, Gujarat, India to provide institutional support for scouting, spawning, sustaining and scaling up the grassroots innovations across the country.
NIF conducts a biennial national competition for grassroots green technologies (not highly advanced) developed by farmers, mechanics, artisans and others through their own genius without any recourse to professional help.
NIF validates these innovations with the help of experts, and, ascertains the novelty in these innovations by doing prior art search. If the innovation is deemed novel, NIF files a patent on behalf of the innovator. NIF also funds value addition initiatives in these innovations to upscale them and make them more useful for a larger segment of people.
