Interspecies Blastocyst Complementation (IBC) (i.e., complementation by microinjecting stem cells of other species into blastocyst-stage embryos) successfully generated rat forebrain tissue in mice which was structurally and functionally intact. In a related study, it was also found that the...
Voyager 1, the most distant man-made object in history, has resumed sending signal to the Earth after a gap of five months. On 14 November 2023, It had stopped sending readable science and engineering data to Earth following a...
Biosynthesis of proteins and nucleic acid require nitrogen however atmospheric nitrogen is not available to eukaryotes for organic synthesis. Only few prokaryotes (such as cyanobacteria, clostridia, archaea etc) have the ability to fix the molecular nitrogen abundantly available in...

The formation of our home galaxy Milky Way began 12 billion years ago. Since then, it has undergone a sequence of mergers with other galaxies and grew in mass and size. The remnants of building blocks (i.e., galaxies that...
In the last 500 million years, there have been at least five episodes of mass extinctions of life-forms on the Earth when more than three-quarters of the existing species got eliminated. The last such large-scale life extinction occurred due...

A fossilised forest comprising of fossil trees (known as Calamophyton), and vegetation-induced sedimentary structures has been discovered in the high sandstone cliffs along the Devon and Somerset coast of Southwest England. This dates from 390 million years ago which...
James Webb Space Telescope (JWST) has taken near-infrared and mid-infrared images of the star-forming region NGC 604, located nearby in the neighbourhood of home galaxy. The images are most detailed ever and offer unique opportunity to study high concentration...
Europa, one of the largest satellites of Jupiter has a thick water-ice crust and a vast subsurface saltwater ocean beneath its icy surface hence suggested to be one of the most promising places in the solar system to harbour...
A new species of sea slug, named Pleurobranchaea britannica, has been discovered in the waters off the southwest coast of England. This is the first recorded instance of a sea slug from the Pleurobranchaea genus in UK waters.
