GUWAHATI Apple farm waste may soon help protect metal pipes, machinery, and infrastructure from corrosion. An international research team led by Nagaland University (NU) has found a way to turn discarded apple leaves into a highly effective, eco-friendly corrosion inhibitor, offering up to 96.2% protection for copper in harsh chemical conditions. The study, carried out...

A new state of matter appears to be a solid-liquid hybrid, scientists from Ulm University in Germany and the University of Nottingham in the UK have reported in the journal ACS Nano. The newfound material isn’t a slush or a gel in the macroscopic sense but refers to a specific atomic structure where different parts...

Every morning, you perform a small physics activity without realising it. You squeeze toothpaste out of a tube. You apply a force and the paste flows out like a liquid. When you stop squeezing, the toothpaste stays on the brush, holding its shape against gravity. It doesn’t drip, spread or collapse into a puddle. This...

A: In weather science, ‘visibility’ is a colloquial term for a quantity called the meteorological optical range. It’s defined as the distance a beam of light can travel through the atmosphere before its intensity drops to 5% of its original value. In an older time, a human observer would stand at a point and look...

The story so far: On January 12, the Indian Space Research Organisation’s (ISRO) PSLV-C62 mission lifted off from Sriharikota carrying the EOS-N1 satellite along with 15 co-passenger satellites. Within minutes, ISRO said the mission had “encountered an anomaly during end of the PS3 stage”, and that a detailed analysis was initiated. What was the anomaly? In a televised briefing after the launch, ISRO chairman...
