A new ghost shark, Rhinochimaera costaricana, was found off Costa Rica. Researchers identified this deep-sea species, which has a long snout. Three male specimens were collected between 2000 and 2023 from depths of 390 to 787 metres. This discovery adds a fourth species to the Rhinochimaera genus.
NASA's Perseverance rover found complex carbon molecules in ancient Martian rocks. This discovery, made in an old river valley, is a big clue in the search for alien life. Scientists say these organic signatures are very compelling, adding to evidence that Mars may have once supported life.
IIT Kanpur researchers, led by Prof. Arun K Shukla, used cryo-EM to solve the mystery of C5aR2, an immune receptor. They found its internal structure differs, causing atypical signalling. They also developed a molecule, R8Y, that selectively targets C5aR2, advancing drug design for immune responses.
Astronaut Shubhanshu Shukla's memoir, The Second Orbit, shows no astronaut goes to space alone. He got selected for the Axiom-4 mission and became the first Indian to step aboard the ISS. The book highlights many individuals whose work makes spaceflight possible, from engineers to his family.
Four mega earthquakes rocked 3 continents on June 24-25. Venezuela got two strong quakes, followed by Japan and then California. Many wondered if they were linked, but experts said no. The events happened in different tectonic settings, thousands of kilometres apart, and are considered a natural coincidence.
Two earthquakes, a magnitude 7.2 and 7.5, struck Venezuela on Wednesday evening. At least 32 people died and over 700 got injured. The tremors shut the main airport and subway. Scientists use seismographs to detect waves and measure magnitude. The death toll is expected to rise.
A solar storm is hitting Earth this week. A large sunspot group rotated into view on Wednesday, June 24. A fast stream of charged particles is flowing towards us. A minor geomagnetic storm is possible late on Thursday, June 25 and into Friday, June 26. India may see auroras.
An astronaut star projector, a kid-approved favorite, is now on sale for $15.19. This device fills a room with lights and lasers, helping children sleep. It has a built-in timer and has been a hit for years, with many users pleasantly surprised by its performance and value.
Two NASA astronauts will step outside the International Space Station for a 7-hour spacewalk on June 30. They will replace a faulty wrist joint on Canadarm2, a critical piece of equipment that has been operating for over 25 years. Preparations are already underway, with astronauts testing spacesuits and reviewing repair simulations.
An international team discovered two rare "super-puff" planets, TOI-791 b and TOI-791 c, orbiting a star 1,110 light-years away. These giant planets, roughly Jupiter-sized, have densities lower than candy floss. They are locked in a rare gravitational resonance, making them fascinating for studying planet formation.
Researchers developed new proteins for deeper tissue imaging. These proteins glow in near-infrared and short-wave infrared light, which penetrates tissue better. The study, published in the Journal of the American Chemical Society, showed these redesigned proteins can visualize biological structures with high sensitivity in cell cultures and animal tests.
NASA's SWOT satellite got a rare, wide view of a tsunami from a July 29 magnitude 8.8 earthquake. Scientists expected a simple wave but found it spread and scattered across the Pacific. This discovery, using SWOT's 120 km wide view, could improve tsunami forecasting and coastal risk understanding.
