Pyricularia is notorious in inflicting a blast disease in monocot plants such as rice, wheat and barley.
The 1st time of Pyricularia has been reported in ginger crop in 2024 in areas of Kodagu district in Karnataka.
When the infection has found ground, it spreads very fast and within hours, the whole field is covered.
In 10 hours over large regions with some of the fields affected up to 20 km apart.
Quipu superstructure
Astronomers have reported what may be the biggest structure that has been detected in the known universe.
This large formation is called "Quipu."
It measures around 1.3 billion light-years or so in diameter and has about 200 quadrillion solar masses.
The size of Quipu is magnified by 13,000 times that of the Milky Way.
It is by far the oldest structure in the universe and outdoing the previous record holders such as the Laniakea supercluster.
Four other giant superstructures were discovered along with it: the Shapley supercluster, the Serpens-Corona Borealis superstructure, the Hercules super cluster and the Sculptor-Pegasus superstructure.
The combination of all these five superstructures comprises approximately 45 per cent of galaxy clusters, 30 per cent of galaxies and 25 per cent of the matter in the universe.
They occupy about 13 per cent of the volume of the universe.
LVM-3's cryogenic engine
ISRO has been able to carry out the ignition test of the local CE20 cryogenic engine.
It will drive the upper stage of the powerful Launch Vehicle Mark-III (LVM-III) of ISRO.
Cryogenic engines are very complicated because they operate on supercooled fuels (liquid hydrogen and oxygen).
The Gaganyaan mission, which will need in-orbit ignition, will make use of a human-rated version of LVM-III.
R-37M Missile
Russia has also volunteered to provide India with an opportunity to swap the R-77 air-to-air missile on the wings of the Su-30MKI with the R-37M missile.
The R-37M has another NATO reporting name, AA-13 Axe head.
It is a Russian developed long-range air-air missile.
