Effectiveness of India's maritime preparedness tested in two-day mega exercise
India's preparedness to deal with all possible challenges in the maritime domain, including contingencies from peace to war-time, was tested in a two-day multi-agency military exercise that covered the 7,516 km-long coastline and exclusive economic zone.
The second edition of exercise 'Sea Vigil', which concluded on Wednesday evening, particularly focused on the efficacy of the measures initiated to plug gaps in the coastal security set up following the Mumbai terror attack in 2008, they said.
The Indian Navy said the "envisaged objectives" of the exercise were met by the whole-hearted participation of all stakeholders.
The exercise involved deployment of the entire coastal security apparatus and more than 110 surface assets of the Indian Navy and the Coast Guard participated in the exercise that was billed as India's largest coastal defence drill, the officials said.
In sync with the national security doctrine, the Indian Navy significantly increased its deployment of warships, submarines and other assets in the Indian Ocean Region, in an attempt to send across a message to China that Indian armed forces are fully prepared to deal with any challenge.
Indian Army to induct first batch of women chopper pilots by 2022
Indian Army will deploy the first batch of women helicopter pilots by 2022 after their induction into the Aviation Corps of the Indian Army.
Army chief General MM Naravane confirmed the news. "One month ago, orders were passed and the proposal has been initiated," he said while addressing the media on the eve of the Army Day.
Till now, the women officers in the Army were serving in the Air Traffic Control and ground duties. "The batch of officers to begin will join the next course starting from July." said the General.
Concurrence was sought from the three-related branches of the Army Aviation Corps, Military Secretary Branch, and the Adjutant General's branch and they all concurred with the proposal, General Naravane said.
The Army Aviation pilots train jointly with the Air Force and their conversion training is done in the Army Aviation School at Nasik.
World's oldest known cave painting found in Indonesia
Archaeologists have discovered the world's oldest known cave painting: a life-sized picture of a wild pig that was made at least 45,500 years ago in Indonesia. The finding described in the journal Science Advances on Wednesday provides the earliest evidence of human settlement of the region.
Co-author Maxime Aubert of Australia's Griffith University told AFP it was found on the island of Sulawesi in 2017 by doctoral student Basran Burhan, as part of surveys the team was carrying out with Indonesian authorities.
The Leang Tedongnge cave is located in a remote valley enclosed by sheer limestone cliffs, about an hour's walk from the nearest road. It is only accessible during the dry season because of flooding during the wet season -- and members of the isolated Bugis community told the team it had never before been seen by Westerners.
Measuring 136 by 54 centimeters (53 by 21 inches) the Sulawesi warty pig was painted using dark red ochre pigment and has a short crest of upright hair, as well as a pair of horn-like facial warts characteristic of adult males of the species.
To make handprints, the artists would have had to place their hands on a surface then spit pigment over it, and the team are hoping to try to extract DNA samples from residual saliva.
SCIENCE AND TECH
Scientists produce electron gas with ultra-high mobility
Recently, Institute of Nano Science and Technology (INST), an autonomous institution of Department of Science and Technologyhave produced electron gas with ultra-high mobility.
2d-electron gas (2DEG) is an electron gas with ultra-high mobility, which can speed up transfer of quantum information and signal from one part of a device to another and increase data storage and memory.
Strong spin-orbit coupling and relativistic nature of the electrons in the 2DEG resulted in Rashba field.
Rashba effect consists of splitting of spin-bands in an electronic system, might play a key role in spintronic devices.
Due to the high mobility of the electron gas, electrons do not collide inside the medium for a long distance and hence, do not lose the memory and information.
Indian women hockey team working on PC conversion and defence: Gurjit
Gearing up for its first international assignment in almost a year, drag-flicker Gurjit Kaur on Thursday said the Indian women hockey team is paying more attention to penalty corner conversion and defence ahead of its clash against formidable Argentina.
The Indian team will begin the eight-match tour against the world number two side.
"Playing against a strong team like Argentina on their home ground won't be easy but our focus will be on bringing out our best play against them. We worked really hard on our fitness over the past 11 months in SAI and the aim was to return to our best form. It is against teams like Argentina where we can test our potential," said Gurjit.
