the quantity of energy produced by fusion in December 2021.

 

It has generated approximately 12 MW of electricity in five seconds which is sufficient to serve the needs of approximately 10,000 homes during that duration.

 

At least 43 Fusion research companies existed in over 10 countries.

 

Discovery of LID-568

 

The Chandra X-ray observatory and the NASA James Webb Space Telescope (JWST) have found a weird black hole.

 

This new black hole was named LID-568.

 

It is a low-mass supermassive black hole which existed 1.5 billion years after the Big Bang.

 

The black hole was accreting 40 times as much as the Eddington limit on an enclosed haze of matter.

 

It is the rate at which a black hole consumes matter that is regulated by what astronomers refer to as the Eddington limit.

 

Deep Seek AI - China

 

In the recent past, Deep Seek has introduced its AI models - DeepSeek-V3 and DeepSeek-R1 which is a reasoning model.

 

These models are rapidly overtaking ChatGPT to become the most downloaded app on the App Store.

 

Deep Seek models are open-source as opposed to the closed models of OpenAI and Google.

 

Gaia BH3 black hole

 

Astronomers have found a super giant black hole called Gaia BH3 lurking near earth, the third one.

 

The 33 solar masses of BH3 would comfortably beat the existing heavyweight, Cygnus X-1 in the galaxy, by 12 solar masses.

 

Gaia BH3 is 2,000 light years distant in the constellation Aquila.

 

The European Space Agency Gaia telescope found all three.

 

In confirmation of the formation of black holes as one of the main predictions of the theory of general relativity, the 2020 Nobel Prize in Physics was awarded.

 

FEAST software by ISRO

 

The most recent release of Finite Element Analysis of Structures (FEAST) software was released by ISRO.

 

FEAST software is a structural analysis software that employs finite element method to analyse the behaviour of structures under different loads in aerospace, automobile, civil, mechanical and marine engineering.

 

It enables engineers to take designs through testing in a virtual form before they build.

 

1st Kangaroo embryos

 

This is because scientists have managed to generate the first kangaroo embryos using in vitro fertilisation (IVF).

 

The world is exploring IVF in order to preserve endangered species.

 

In January 2024, researchers in Germany implanted into a surrogate the embryo of the first rhino in the world to be created using IVF.

 

Pyricularia Spp Infection

 

A new fungal disease named Pyricularia Spp that affected ginger crops severely was identified by the ICAR-Indian Institute of Spices Research (IISR).

 

Pyricularia Spp is a fungi pathogen and a causative agent of a blast disease that is a novel threat to ginger cultivation.

 

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
