A-to-I mRNA Editing in Animals : Study Researchers from China recently reported that it’s hard to make sense of the widespread persistence of A-to-I mRNA editing in animals. Researchers identified 71 genes in graminearum that contain premature stop codons (UAG) in their unedited mRNA. These were termed PSC (premature stop codon-containing) genes. Deleting these genes […]

Polar Satellite Launch Vehicle: C61 ISRO launched the PSLV-C61 mission from Sriharikota to place the EOS-09 satellite into a Sun-synchronous polar orbit. The mission failed due to a third-stage issue. PSLV stands for Polar Satellite Launch Vehicle, a four-stage launch vehicle developed by the Indian Space Research Organisation (ISRO). It is primarily designed to place […]

GRAIL Mission : NASA NASA’s GRAIL mission recently unveiled significant differences between the moon’s nearside and farside, attributing them to tidal deformation and varied volcanic activity. Gravity Recovery and Interior Laboratory (GRAIL) is a NASA lunar mission launched in 2011. It consisted of two robotic spacecraft, Ebb and Flow, which orbited the moon to create […]

Bird-Wing Eruption: A massive solar flare event, named the “bird-wing” eruption, was observed on the Sun’s northern hemisphere and is expected to impact Earth.A visually dramatic solar eruption with plasma shaped like wings, observed by NASA satellites. The ejected plasma stream spanned over 1 million km, twice the Earth-Moon distance. It Involved both a solar […]

Shingles Disease: A recent large-scale study from South Korea, published in the European Heart Journal, reveals that individuals vaccinated against shingles have a 23% lower risk of cardiovascular events, including heart attacks and strokes. Shingles, also known as herpes zoster, is caused by the reactivation of the varicella-zoster virus, the same virus responsible for chickenpox. […]

Multi Agency Centre: The Union Home Minister recently inaugurated the revamped Multi Agency Centre (MAC). MAC is a national intelligence-sharing fusion centre under the Intelligence Bureau (IB) where states and central agencies and police forces coordinate to share, store, collate, and analyse inputs on terrorism on a daily basis under four heads – J&K, Northeast, […]

India-Japan’s LUPEX Mission Enters Design Phase: India and Japan have taken a major step in their joint lunar exploration effort with the Chandrayaan-5 mission, also known as LUPEX (Lunar Polar Exploration). The mission, which aims to study the presence of water and water-ice on the Moon’s surface and subsurface, is set to enter the design […]

India Explores Human Sustainability in Space under BioE3 Policy: India is poised to conduct its first-ever biological experiments aboard the International Space Station (ISS) as part of the AXIOM-4 mission, marking a crucial step in exploring the sustainability of human life in space. These experiments, in collaboration between ISRO and the Department of Biotechnology (DBT), […]

Active Galactic Nuclei: Astronomers from the Russian Academy of Sciences, using the Spektr-RG (SRG) space observatory, have detected 11 new Active Galactic Nuclei (AGNs) during their all-sky X-ray surveys. Active Galactic Nuclei (AGNs) are compact regions at the centers of galaxies that emit exceptionally high levels of electromagnetic radiation, often outshining the rest of the […]
