	Description:		President Vladimir Putin has just announced a whole new suite of strategic nuclear systems being developed in Russia. One of these is a worrying nuclear-powered cruise missile. Worrying - because back in the 1960’s the US tried something similar with their Project’s Pluto and SLAM and it turned out the missiles were too dangerous even to test. We find out how likely experts in the field think these claims are. International Women’s Day (Thursday 8th March 2018) Around the world, more and more women are becoming farmers and responsible for small holdings. Climate change is impacting women globally more than men, a good example is women tend to fetch water and water sources are becoming more scarce, so they have to travel further each day. Agriculture is first in the firing line when it comes to the negative impact of climate change. Is anyone doing anything to mitigate this double-whammy impact on women around the world? Long-term Impact on Fisheries from Climate Change. Changes in the cycling of nutrients in the world’s oceans are already occurring. Global warming is having an impact on the marine food chain already. Nutrients needed to feed phytoplankton, the first organisms in the food chain, are being locked up at depth. This means less food for the larger organisms, including fish. The decline has been predicted to be low and slow for the next 100 years. But new work has pushed the models further into the future and have shown much greater declines in fish stocks around the whole world by 2300. Looking for Ice in Diamonds Diamonds look nice on rings and necklaces, but they can also have uses beyond ornamentation. In a recent study, geologists have found minute traces of a new form of ice in diamonds from deep within the Earth’s mantle. Could this be evidence of an untapped ocean beneath our feet?
