India’s digital payment journey has evolved from passwords, PINs and OTPs to fingerprints and facial authentication, making transactions faster and more seamless. Now, with AI, the next step could be completely hands-free payments, where systems recognise users, assess transactions and authenticate payments almost invisibly.The country may allow AI agents to make small UPI payments without…

The site was decommissioned. However, contamination remains underground. In 1967, the United States tried an unusual method to increase natural gas production. It detonated a 29-kiloton device and had an explosoion 4,227 feet below the ground in north-western New Mexico to stimulate the flow of natural gas.According to the US Department of Energy (DOE), the…

Human beings have always been drawn towards challenges that appear difficult, uncertain or even impossible. From exploring unfamiliar places to developing new technologies and solving scientific problems, progress often begins with the decision to attempt something that has never been done before. Astronaut Neil Armstrong, the first person to walk on the Moon, once offered…

On August 30, thousands of Bengalureans gathered at Lalbagh and marched towards the iconic rock. It has been standing in what is now Bengaluru for billions of years, long before humans, cities or even the Himalayas existed.

A fungus infecting goldenrod soldier beetles can alter their behaviour before death and cause changes to their bodies afterwards. Researchers investigating Eryniopsis lampyridarum found infected Chauliognathus pensylvanicus beetles clamped their mandibles tightly onto flower heads shortly before dying. Between 15 and 22 hours after death, the fungus caused the beetles to raise their hardened forewings…

Visual observations indicated a retention time of about 61 minutes in Cell 3 and 66 minutes in Cell 4. Monastery Run Wetland 1, near Latrobe, Pennsylvania, was built in 1997-1998 as a passive treatment system for several discharges from an abandoned underground mine. Adequate retention time for iron removal from mine water before discharge to…

A crab shell left behind after a meal might seem destined for the bin, but scientists have found a very different use for it. Engineers at the University of Maryland have turned material derived from discarded crustacean shells into part of a zinc battery, using chitosan to make its electrolyte. The unusual ingredient is tied…

Both McDermott Lake and Sandy Beach Lake had previously supported natural walleye recruitment. Scientists removed about 285,000 warm-water fish from a Wisconsin lake over four years in an attempt to help its declining walleye population recover. The large-scale experiment reduced several fish species and was followed by a sharp rise in yellow perch. However, it…
