Organic farming can actually be more profitable than using fertilizers and pesticides – Quartz

By Deena Shanker | June 9, 2015 Despite the many environmental benefits of organic farming—it’s better for soil, water, air, and climate change—it’s often written off as economically unfeasible for farmers. That’s largely because the same patch of land will produce less food when farmed without the synthetic fertilizers, pesticides, and other tools used in conventional agriculture. But according to a new study published in the Proceedings of the National Academy of Sciences, organic …

MSU organic farming study finds diverse benefits using sheep : Ag Weekly

… research, education and extension project, which is showing several environmental and economic benefits for an integrated cropping and livestock system, according to Perry Miller, MSU professor of land resources and environmental Sciences who is part of the research team. Miller said that in a typical organic farming system, tillage is used to terminate cover crops and to get rid of unwanted weeds. However, frequent mechanical tilling can disrupt soil structure and reduce organic matter, …

Insect-inspired eye may allow drones to navigate their environment more naturally

… autonomous capabilities of drones by endowing them with more natural flying abilities. To this end, researchers working at Aix-Marseilles University’s Institut des Sciences du Mouvement Etienne-Jules Marey in France have built a bee-inspired flying robot that incorporates what is known as optic flow visual navigation. This is where, in a compound insect eye, the area to the front of a flying insect remains relatively stable in the sight, but to either side, objects and terrain as they …

… Sciences. “This information is crucial for developing and validating numerical models that predict how the ice sheet may change and contribute to global sea level over the next few hundred years,” said co-author Prof Cornelis J. van der Veen of the University of Kansas. Dr Csatho, Prof van der Veen and their colleagues produced the first comprehensive study of how the Greenland Ice Sheet is losing mass based on satellite and airborne data at nearly 100,000 locations across Greenland. …

Huge New Holes In Siberia Have Scientists Calling For Urgent Investigation Of The Mysterious Craters

… more craters on Yamal, we just need to search for them… I suppose there could be 20 to 30 craters more,” Prof. Vasily Bogoyavlensky, a corresponding member of the Russian Academy of Sciences and deputy director of the Moscow-based Oil and Gas Research Institute, told The Siberian Times. “It is important not to scare people, but to understand that it is a very serious problem and we must research this.” Researchers ventured deep inside one of the holes last November, …
