CO2 Mitigation on Earth and Magnesium Civilization on Mars

Excessive CO2 emissions are a major cause of climate change, and hence reducing the CO2 levels in the Earth’s atmosphere is key to limit adverse environmental effects. Prof. Vivek Polshettiwar's group at Tata Institute of Fundamental Research (TIFR), Mumbai, employed magnesium to convert CO2 to methane, methanol and formic acid, using water as the sole hydrogen source. The conversion of CO2 (or air) took place within a few minutes at ambient [...]

Early life stress and programming psychiatric risk

What we experience as a child often has a lasting impression on our behaviour throughout the course of our life. Stressful and adverse experience during early life of an individual can often lead to a lasting vulnerability towards developing psychiatric disorders in adult life, a question particularly pertinent to the current times when depression has emerged as one of the greatest challenges to global health. In a recent study, the Vaidya lab [...]

Glimpse into self-interaction of Higgs boson

The Higgs boson (H), discovered in 2012 by the ATLAS and CMS experiments, is the pinnacle of the scientific results obtained so far from the CERN-LHC. All the fundamental particles, known till now, gets their intrinsic mass via interactions with H and the interaction strength determines the mass of the particle.

A new twisted graphene system hosts chargeless valley current

In a recent study, the Nanoelectronics lab in TIFR has found a novel route to generate and detect a chargeless valley current. Valleys represent energetically degenerate but structurally distinguishable points in the band structure of a material. Whenever electrons associated with a particular valley quantum number flow, it gives rise to a dissipationless valley current where the net electronic charge transferred is zero--this can potentially be [...]
