Conventional bombs explode on or near a target surface, with the explosion and fragments, e.g. shrapnel, rendering the bomb’s damage. But when a target is buried deep under a mountain, the soil and rock mass surrounding it can absorb enough of the blast’s energy to keep the target from being damaged too much. This is…

The view that artificial intelligence (AI) can pose an existential threat to humankind using technologies like nuclear weapons has been around for some years now. Last year, after examining such threats and risks, one study from the Rand Corporation, a global policy think-tank, argued that such risks could not be ruled out. The study also…

A new study led by researchers from the National Centre for Biological Sciences (NCBS) and other institutions has compiled InvenTree-meta, the largest meta-dataset of tree inventory studies from India. The database brings together information from 465 published studies conducted between 1991 and 2023, spanning more than 4,650 hectares of forests across all of India’s biomes. Contributing to global…

‘Maglev’ is a portmanteau of ‘magnetic levitation’. Instead of running on wheels, maglev technology uses strong magnetic fields to lift the train and move it forward. Since the train floats above the track, there is no rolling friction during normal operations, nor are operations affected by inclement weather, like rain or snow. The result: the…
