A team of astronomers at the National Centre for Radio Astrophysics (NCRA) in Pune, India have discovered a mysterious ring of hydrogen gas around a distant galaxy, using the Giant Metrewave Radio Telescope (GMRT). The ring is much bigger than the galaxy it surrounds and has a diameter of about 380,000 light-years (about 4 times that of our Milky Way).
Have you ever wondered how the Sun creates the energy that we get from it every day and how the other elements beside hydrogen have formed in our universe? Perhaps you know that this is due to fusion reactions where four nuclei of hydrogen join together to produce a helium nucleus. Such nucleosynthesis processes are possible solely due to the existence, in the first place, of stable deuterons, which are made up of a proton and a neutron. Probing [...]
Global warming is a serious threat to the planet and the living beings. One of the main cause of global warming is the increase in the atmospheric CO2 level. The main source of this CO2 is from the burning of fossil fuels in our daily lives (electricity, vehicles, industry and many more). Researchers at TIFR have developed the solution phase synthesis of Dendritic Plasmonic Colloidosomes (DPCs) with varying interparticle [...]
Mitochondria in neurons are the powerhouses that generate energy to execute cellular functions and regulate neuronal survival under conditions of stress. Collaborative research by Prof. Vidita Vaidya and Prof. Ullas Kolthur-Seetharam groups at TIFR, along with Dr. Ashok Vaidya, at Medical Research Centre, Kasturba Health Society, has demonstrated an unusual function for the neurotransmitter serotonin, in the generation of new mitochondria—a [...]
Our understanding of the gravitational force has been evolving over centuries, but we still do not have the final picture. Newton showed that the force which makes planets go around the sun is the same as the gravitational force which makes objects fall to the ground. This led to the discovery of the famous inverse square law of gravitation.
