Inventions / Discoveries
According to a new study conducted by scientists in collaboration with the UN Food and Agricultural Organization (FAO), two new groups of wheat rust have been identified that posed threat to wheat produced in Africa, Asia and Europe in 2016.
Note : As per the data, the two new groups have been identified as yellow rust and stem rust. The finding calls for the need for early detection and rapid action to keep the fungus under control.
Examining a molecular cloud with enigmatic motion, a team led by researchers in Japan has found signs of stray black hole hiding in the Milky Way. Theoretical studies have predicted that 100 million to one billion black holes should exist in the Milky Way, although only 60 or so have been identified through observations to date.
Note : The researchers used the ASTE Telescope in Chile and the 45-m Radio Telescope at Nobeyama Radio Observatory both operated by the National Astronomical Observatory of Japan, to observe molecular clouds around the supernova remnant W44, located 10,000 light-years away from us.
Volcanic Activity
Scientists have uncovered evidence of at least two billion years of volcanic activity on Mars, after analysing a meteorite from the red planet. The finding confirms that some of the longest-lived volcanoes in the solar system may be found on the red planet.

The largest Martian volcano, Olympus Mons, is nearly 27.3 kilometres high. That is almost triple the height of Earth's tallest volcano, Mauna Kea, at 10 kilometres.
The meteorite, known as Northwest Africa 7635 and discovered in 2012, was found to be a type of volcanic rock called a shergottite. Eleven of these Martian meteorites, with similar chemical composition and ejection time, have been found.

Scientists from California National Primate Research Centre, US have successfully test-ed a new male contraceptive 'Vasalgel' that blocks sperm flow on monkeys.
Note : During the animal trials, the Vasalgel contraceptive provided effective birth con-trol in rhesus monkey groups for more than one year. Now it is waiting for human trials. It brings the prospect of an alterna-tive form of birth control for humans.
ISRO...
Indian Space Research Organization has stated that the indigenous development of Telemetry & Telecommand Processor (TTCP) has been realized and its production will be initiated with the help of Indian industry. This development was taken up by ISRO as part of 'Make in India' campaign, replaces expensive imported equipment.
Note : The interplanetary spacecraft use an international standard known as Consultative Committee for Space Data Systems (CCSDS), and presently equipment are being imported for telemetry reception and telecommand transmission requirements. It will be used in Integrated Spacecraft Testing of Low Earth Orbit, Geostationary Orbit and Interplanetary Spacecraft.
The US and Japanese military have success-fully tested the Standard Missile-3 (SM-3) Block IIA missile defence system by inter-cepting a medium-range ballistic missile tar-get in space for the first time. The missile was launched from a ship off the west coast of Hawaii, US. As per the US Missile Defence Agency, the defence system met each of its primary objectives.
AAD Missile...
India successfully test-fired its home-grown Advanced Air Defence (AAD) interceptor missile from launching complex-IV of Dhamara Abdul Kalam defence base off Odisha coast on 11th Feb, 2017. It is capable of destroying the incoming missile in the endo-atmospheric region at a low altitude of less than 30 kilometres.
Features : The interceptor is a 7.5-metre-long single stage solid rocket propelled guided missile equipped with a navigation system, a hi-tech computer and an elec-tro-mechanical activator would intercept a target, mimicking an incoming enemy mis-sile, mid-air.
PSLV-C37
The PSLV, in its 39th flight (PSLV-C37), will launch the 714 kg Cartosat-2 series satellite for earth observation along with 103 co-passenger satellites, together weighing about 664 kg at lift-off. PSLVC37/ Cartosat-2 Series Satellite Mission is scheduled to be launched on February 15, 2017 at 9.28 hours 1ST from SDSC SHAR Sriharikota.
Note : The co-passenger satellites comprise 101 nano- satellites, one each from Israel, Kazakhstan, the Netherlands, Switzerland, United Arab Emirates (UAE) and 96 from United States of America (USA), as well as two from India.
Scientific Events
Indian Navy's survey vessel INS Sarvekshak, based at the Southern Naval Command in Kochi became the first naval ship to go green by installing a solar power system on board. It has innovatively deployed the zero-mainte-nance solar power system, and is capable of generating 5.4 KW electricity and replacing the ship's traditional 4.4 KW emergency diesel alternator.
Note : The low cost system will slash a yearly carbon emission of 60,225 kg and save around 22,995 litres of diesel used to run the vessel's emergency diesel alterna-tor. *
