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 [...]

Upgraded GMRT measures the mass of hydrogen in distant galaxies

A team of astronomers from the National Centre for Radio Astrophysics Pune, and the Raman Research Institute (RRI), Bengaluru, has used the upgraded GMRT to measure the atomic hydrogen content of galaxies 8 billion years ago. This is the earliest epoch in the universe for which there is a measurement of the atomic gas content of galaxies. This research has been published in the 14 October 2020 issue of the journal Nature.
