Recently, for two consecutive days, Delhi reported daytime temperature above 50 degree C, the highest ever recorded in the city. There is a reason why cities are experiencing higher temperatures than non-urban and rural areas. The ongoing climate change and rapid urbanisation are now defining the Anthropocene, with the cities experiencing both thereby making the...

Indian scientists have demonstrated a quantum-secure communications link through open air across more than five times the distance covered in a similar test last year. In the latest demo, on the night of September 27-28, scientists connected the Bhaskaracharya National Institute for Space Applications and Geo-informatics (BISAG-N) and IIT-Gandhinagar. QNu Labs from Bengaluru supplied the...

Investigators in Argentina are trying to solve the mystery of baby whales washing up dead in unusually high numbers along the country’s Patagonian coast. Scores of the calf carcasses have been washing ashore around Peninsula Valdes, a major breeding ground for southern right whales in Argentina’s Chubut province. Hunted to the brink of extinction in...

Breaking up forests is just as bad for global warming How broken up a forest is can affect local temperatures as much as the forested area, a new study has found. Using satellite data, researchers found that in tropical and temperate zones, dividing continuous forests into smaller, isolated patches significantly raised surface temperature. In high-altitude...

The field of molecular biology began when scientists attempted to answer a simple question: what molecule makes up the genetic material of an organism? In the early 1900s, when the field was still in its infancy, there were two plausible candidates: nucleic acids (DNA and RNA) and proteins. At the time, proteins were the preferred...

India’s cities are bustling with taller buildings and more densely packed populations. The hotter days in many of these cities also come with high humidity, and can make the experience of heat seem unforgiving. One of the reasons is often a perceived lack of winds, which often have to make their way through the nooks...

AI agents don’t go rogue. That’s something only humans do. Nevertheless, a New York Times article – representative of much news coverage of AI – described an OpenAI hacking as “A.I. bots going rogue and independently spearheading a cyberattack.” Name-brand artificial intelligence agents have been on a hacking spree in 2026. OpenAI’s software agents hacked...
