Scientists identify vital mechanisms controlling skin regeneration
Updated : 2 years, 9 months ago IST
The outer layer of skin, the epidermis, is constantly turning over to replace dead or damaged cells throughout our lifetime. Skin stem cells need to continuously make decisions: either make more copies of themselves (self-renewal) or switch their fate towards differentiation. The molecular m

Research: Short gamma-ray bursts traced farther into distant universe
Updated : 3 years, 8 months ago IST
Astronomers have developed the most extensive inventory to date of the galaxies where short gamma-ray bursts (SGRBs) originate. Using several highly sensitive instruments and sophisticated galaxy modeling, the researchers pinpointed the galactic homes of 84 SGRBs and probed the characteristi

Supernova in distant space allows us to understand the origin of elements
Updated : 3 years, 8 months ago IST
A supernova is a stellar explosion, which occurs when the lives of some really massive stars come to an end. In this violent epilogue, the star expels the material from its outer layers by means of a shock wave, allowing us to see the various elements it was composed of.
