India's first CDS
Indian Army chief General Bipin Rawat has been named India's first Chief of Defence Staff (CDS). General Rawat has been named the first CDS a day before he is scheduled to retire from service after his three-year term as the Chief of Army Staff. General Rawat was the frontrunner for the post that was announced just a few days ago.

Materials to produce energy from water
Indian Institute of Technology (IIT) Guwahati Researchers have developed materials that can produce energy from water, on a small scale. According to IIT-Guwahati these new ways of producing energy can be employed in household environments to support the concept of decentralization of energy sources.

Genome secrets of Indian oil sardine
GS Paper - 3 (Biotechnology)

In a major breakthrough in marine fisheries research, a team of scientists at the ICAR-Central Marine Fisheries Research Institute (CMFRI) has decoded the whole genome of the Indian oil sardine, a popular food fish. This is the first time that the genome of a marine fish species from the Indian subcontinent has been decoded, a CMFRI statement said.

More about the News

This development is a 'milestone' in Indian marine fisheries, the decoded genome will be a valuable resource for understanding the biology, ecology and evolution of the oil sardine (Sardinella longiceps).
This critical genome data could be used to improve the management strategies for the conservation and sustainable utilisation of this fish.
The decoded genome is 1.077 Gb in size and contains a total of 46316 protein coding genes.
This landmark research accomplishment was achieved through the cutting-edge Next Generation Sequencing technology by a group of researchers led by Dr Sandhya Sukumaran, Principal Scientist at Marine Biotechnology division of the CMFRI. This research has been published in the high-impact journal Scientific Data of the Nature Group.
Indian oil sardine is a vital fisheries resource in the Indian subcontinent, contributing substantially, approximately 10 per cent, to the total marine fisheries industry in India.
This fish is a trans-boundary resource and the whole genome information can also be utilised for certification of the fishery and identification of the origin of catch for monitoring clandestine trade and tracking the movement of this enigmatic fish.
Small pelagic fishes like the Indian oil sardines can be considered as model organisms to study the climatic as well as fishing impacts on the Indian Ocean resources, as they respond to variations in environmental and oceanographic parameters.
About Sardines

Sardines are an ecologically important part of the marine ecosystem, as they form an intermediate link in the food web and serve as prey for larger predators.
The genome assembly of the sardines is a valuable tool for studying how fish adapt to climate change.
Genetic and genomic investigations found that Indian oil sardines exist in two highly distinct stocks, one in Indian waters and another in the Gulf of Oman.
Understanding these genetic differences could help researchers comprehend how environmental and oceanographic conditions impact this species in different regions of the Northern Indian Ocean.
The CMFRI statement said the researchers have also identified the genes involved in the biosynthesis of polyunsaturated fatty acids (PUFA) of the oil sardine, offering insights into the genomic mechanisms behind the high nutritional quality of these sardines.
Oil sardines are a good source of these fatty acids, which play a crucial role in maintaining human health.
