The iPhone 17, launched at Rs. 82,900, looks to be the most value-for-money iPhone to buy this year. With meaningful upgrades such as a ProMotion display, better battery life, and improved camera sensors, Apple has made it a much better deal overall. This year, Apple has poured so many upgrades into its standard model that I’ll recommend it to most people, not just first-time iPhone buyers or those on a budget.

Researchers at The Ohio State University have turned mushrooms into organic memory devices that mimic brain-like computing. The fungal circuits, powered by shiitake and button mushrooms, can switch between electrical states thousands of times per second, offering a biodegradable, low-cost alternative to conventional microchips.

MIT physicists have developed a molecular technique using radium monofluoride that lets electrons probe inside atomic nuclei, replacing particle accelerators and offering new insight into matter–antimatter asymmetry.

New telescope images show interstellar comet 3I/ATLAS ejecting a giant jet of gas and dust toward the Sun. Scientists say the phenomenon confirms its natural cometary behaviour, offering clues about how such ancient interstellar visitors react to solar heat.

NASA’s Europa Clipper spacecraft may soon pass through the ion tail of interstellar comet 3I/ATLAS, offering a rare opportunity to sample material from beyond our solar system. Scientists say this encounter could yield valuable insights into the formation and evolution of star systems.

A new super-Earth, GJ 251 c, has been found orbiting a nearby red dwarf star within its habitable zone. About four times Earth’s mass, it may host liquid water. Detected via the radial-velocity method using Penn State’s Habitable Zone Planet Finder, it’s a prime target in the search for life.
