If life ever existed on Mars, traces of it could still be preserved beneath the planet’s icy surface. Recent experiments conducted by NASA and Penn State University suggest that fragments of biomolecules from ancient microbes may survive in Martian ice for tens of millions of years. Laboratory simulations exposed frozen samples of E. coli to…

Mumbai: Sensex rallied to a 52-week high on Friday at above the 84,100-point mark in early trades but end-of-the-session profit taking pulled the index down a bit and it closed 485 points up at just below the 84k mark. Since Tuesday, the sensex has risen nearly 2,000 points or 2.3%.On NSE, Nifty gained 178 points…

A remarkable fossil discovery in China is rewriting our understanding of insect evolution. Scientists have identified a 151-million-year-old fly preserved in amber with features not seen in any modern species. The fossil, found in Liaoning Province, retains ancient wing structures, bristles, and mouthparts that reveal an evolutionary branch previously unknown. According to a 2025 report…

Astronomers have witnessed an extraordinary discovery around the icy celestial body, Chiron between Saturn and Uranus encircled by a developing ring system. This discovery has made an extraordinary glimpse into the formation and evolution of rings around the minor celestial objects and offers insights into the well-known majesty of Saturn’s rings. Due to hybrid characteristics,…

When Myanmar was rocked by a powerful magnitude-7.7 earthquake in March 2025, scientists noticed something unusual. The ground shook harder and faster than expected, and data showed the rupture moved at extreme speeds. Researchers later confirmed it was a supershear or “sonic boom” quake, where the rupture front travels faster than seismic shear waves. This…

Source: The New York Times Scientists have found that a massive earthquake in the Pacific Northwest could trigger a second catastrophic quake along California’s San Andreas Fault. A study published in SciTechDaily reveals that seismic stress from one fault system can transfer to another, creating a dangerous domino effect across the region. This challenges the…

In a laboratory in Norway, scientists have achieved something that sounds like science fiction: turning industrial waste gases into clean, usable fuel. Researchers at the Norwegian Institute of Bioeconomy Research (NIBIO) added specialised bacteria to a reactor and watched as carbon dioxide and hydrogen transformed into nearly pure methane, exceeding 96 per cent purity. This…

Representative image (Picture credit: AP) NEW YORK: Two bright green comets are streaming through the skies and are visible to skygazers in the Northern Hemisphere. Both hail from the outer edges of our solar system – possibly what’s known as the Oort Cloud, well beyond Pluto. Comet Lemmon will have its closest brush with Earth…

Interstellar object 3I/ATLAS has captured the attention of scientists and space enthusiasts around the world. Renowned Professor Brian Cox describes this comet as truly remarkable, offering a rare window into the early universe. Discovered on 1 July 2025 by the Asteroid Terrestrial-impact Last Alert System (ATLAS), it is only the third confirmed interstellar object to…

SAN JUAN ISLAND: As dawn broke over San Juan Island, a team of scientists stood on the deck of a barge and unspooled over a mile of fibre-optic cable into the frigid waters of the Salish Sea. Working by headlamp, they fed the line from the rocky shore down to the seafloor – home to…
