Within the last five years, gravitational observatories have reported detecting a few dozen gravitational wave events in the universe. Here is a report on two such events caused by coalescing of black hole and neutron star.
While examining the rainfall data from the North-East, Indian meteorologists discover that the wettest place on the earth has shifted from Cherrapunji to Mawsynram. What could be the reason? Read on.
LIGO can detect gravitational waves caused by celestial events millions of kilometres away. But quakes caused by events a few kilometres under the earth can mess up the results. Read on to see how scientists overcame the problem.
Hydrogen sulphide, toxic at high concentrations, is an important part of out physiology at very low concentrations. A sensor that is sensitive enough to detect the changes in its concentrations are important in the diagnosis of many diseases. Indian researchers have now found a way, using the chromophore of a fluorescent protein.
Monsoon over India has seen a revival after 2000. But Uttar Pradesh and Bihar are left out. Why? Ramesh Kumar Yadav and Roxy Mathew Koll from the IITM Pune say that the answer may lie in the warming of eastern equatorial Indian Ocean and Rossby gyres.
Researchers from the St Xavier’s College, Mumbai, IIT Bombay and the Bhabha Atomic Research Centre find that the volcanism in Elephanta islands predates the volcanism in Mumbai by more than 3 million years
IIT Bombay and NEERI Nagpur suggest decentralised composting of kitchen and garden waste to alleviate the urban wet gargabge problem. They developed a modified drum technique to accelerate compost production within five weeks.
Researchers from the ICMR-National Institute of Immuno-haematology and KEM Hospital show that there is an easy and quick way to assess babies at risk for mortality due to sepsis: higher variations in red cell sizes.
Researchers from the Shivaji University report gaining control on the morphology of titanium dioxide nano structures. Titanium dioxide crystals resembling cauliflowers are better for application in dye sensitised solar cells, they say.
There are various satellite data products that can help predict rainfall. Which one is best for the purpose? M. Venkatarami Reddy, and Imranali M. Momin from the National Centre for Medium Range Weather Forecasting, and Ashis K. Mitra and D. S. Pai from the India Meteorological Department investigates.
