As fascinating as it is mysterious, dark matter is one of the greatest enigmas of astrophysics and cosmology. It is thought to account for 90 percent of the matter in the universe, but its existence has been demonstrated only indirectly, and has recently been called into question. New research conducted by SISSA removes the recent doubts on the presence of dark matter within galaxies, disproving the empirical relations in support of alternative theories. The study, published in the Astrophysical Journal, also offers new insights into understanding the nature of dark matter and its relationship with ordinary matter. from Phys.org - latest science and technology news stories http://bit.ly/2Leq4sd

A team at the Helmholtz-Zentrum Berlin has succeeded in producing inorganic perovskite thin films at moderate temperatures using co-evaporation - making post-tempering at high temperatures unnecessary. The process makes it much easier to produce thin-film solar cells from this material. In comparison to metal-organic hybrid perovskites, inorganic perovskites are more thermally stable. The work has been published in Advanced Energy Materials. from Phys.org - latest science and technology news stories http://bit.ly/2VzkZyp

The rocket that would carry RISAT 2BR1 is designated as PSLV-C46 as per ISRO's numbering system and will blast off from the first launch pad at the country's rocket port in Sriharikota. Following the launch of RISAT 2BR1, ISRO will send up a cartography satellite Catosat-3.

Vijay Mohan Tribune News Service Chandigarh, April 29 Pegging crop yield loss due to surface ozone at $5 billion for wheat and $1.5 billion for rice, a joint study carried out by scientists from India and Germany has called for an urgent need to conduct strategic ozone observations over agricultural fields and develop a regional emission database to support policy-making in India. “Our estimates reveal a nationwide relative yield loss of about 21 per cent for wheat and 6 per cent for rice. We also estimate loss of about 16 per cent for wheat and 11 per cent for rice in the states of Punjab and Haryana,” the study states. Their findings, the study’s authors claim, are “substantially higher” than earlier such researches. Elevated ozone concentrations near the surface significantly reduce crop yields, which is crucial as the country’s economy and the food security for over a billion people depends strongly on the agricultural productivity. The wheat production in India is expected to

The world's oceans soak up about a quarter of the carbon dioxide that humans pump into the air each year—a powerful brake on the greenhouse effect. In addition to purely physical and chemical processes, a large part of this is taken up by photosynthetic plankton as they incorporate carbon into their bodies. When plankton die, they sink, taking the carbon with them. Some part of this organic rain will end up locked into the deep ocean, insulated from the atmosphere for centuries or more. But what the ocean takes, the ocean also gives back. Before many of the remains get very far, they are consumed by aerobic bacteria. And, just like us, those bacteria respire by taking in oxygen and expelling carbon dioxide. Much of that regenerated CO2 thus ends up back in the air. from Phys.org - latest science and technology news stories http://bit.ly/2VAlZ5s

Melbourne The world's seas are becoming stormier, with extreme ocean winds and wave heights increasing around the globe, a study has found. Researchers from the University of Melbourne in Australia analysed wind speed and wave height measurements taken from 31 different satellites between 1985-2018, consisting of around four billion observations. The measurements were compared with more than 80 ocean buoys deployed worldwide, making it the largest and most detailed dataset of its type ever compiled. The study, published in the journal Science, found that extreme winds in the Southern Ocean have increased by 1.5 metres per second, or 8 per cent, over the past 30 years. Extreme waves have increased by 30 centimetres, or 5 per cent, over the same period. As the world's oceans become stormier, researchers warned this has flow on effects for rising sea levels and infrastructure.
