    AstroSat detected milli-second burst in a new high magnetic field neutron star

    Magnetars are super-strong neutron stars with more powerful magnetic fields than Earth’s. Their magnetic fields decay, emitting high-energy radiation. One such magnetar, SGR J1830-0645, discovered in 2020, is a young, isolated neutron star. Scientists from Raman Research Institute and the University of Delhi used AstroSat to study it in X-ray energies, analyzing its timing and

    Scientists uncover the distribution and physiological role of planteose

    Witchweed (Striga spp.) and broomrapes (Orobanche and Phelipanche spp.) are root parasitic weeds that inflict major losses in agriculture globally. Being obligate parasitic flowering plants in nature, they parasitize other autotrophic plants of agricultural importance. The plants are attached to their host by means of haustoria, which transfer nutrients from the host to the parasite.…
