When working with drug candidates, chemists sometimes like to replace a carbon atom in a ring of atoms with a nitrogen atom. This is because the switch can significantly alter the molecule’s properties, including how well it dissolves or how it interacts with biological targets in the body. But achieving it has been quite difficult,...

The science of Gaganyaan parachutes | Explained
Any spacecraft entering the earth’s atmosphere will rely primarily on atmospheric drag to reduce a significant portion of its velocity as it aerobrakes. Towards the terminal phase, to gently touchdown on land or in sea, additional decelerating systems like parachutes have to be activated to further reduce its velocity to acceptable limits. The parachute used...
NIT-Srinagar to open campus observatory with 14-inch telescope
The National Institute of Technology (NIT) in Srinagar is set to become the first NIT in the country to have a dedicated campus-based observatory equipped with a 14-inch aplanatic Schmidt-Cassegrain telescope, officials said on Monday (September 21, 2026). The telescope provides aberration-free, flat-field images for astrophotography and planetary observation, the officials said. The NIT-Srinagar Observatory...

The crater, dubbed “McGetchin”, measures 730 feet (222 metres) wide, NASA said in a blog post. It is believed...
Science quiz: Scientific problems featuring cities
Biosphere 2, an experiment like no other
The dream of heading out to space and colonising distant celestial bodies isn’t one that is unique to the time we live in. It is one that humans have aspired for long and continue to strive towards, despite the problems plaguing the only known planet that supports life as we know it: Earth. Even as...
