Read More The loss of ‘eternal ice’ threatens Mongolian reindeer herders’ way of life Patches of long-frozen snowpack and ice in the Mongolian steppes are rapidly vanishing — with dire consequences for the reindeer and herders who rely on the icy spots.   Read More Some people with half a brain have extra strong neural connections Brain scans of six people who had half their brains removed as epileptic children show signs of compensation. Read More Dengue cases in the Americas have reached an all-time high There have been more dengue cases in the Americas this year than ever before, according to the Pan American Health Organization. Read More Lead becomes stronger than steel under extreme pressures Lead is a soft metal, easily scratched with a fingernail. But that changes dramatically when the metal is compressed under high pressures. Read More Full intestines, more than full stomachs, may tell mice to stop eating A new description of stretch-sensing nerve endings in mice’s intestines could lead to ways to treat obesity. Read More How Julia Robinson helped define the limits of mathematical knowledge “Rather than being remembered as the first woman this or that, I would prefer to be remembered, as a mathematician should, simply for the theorems I have proved and the problems I have solved.”  — Julia Robinson, born 100 years ago Read More Humpback whales in the South Atlantic have recovered from near-extinction A new count shows the population off Brazil went from about 450 in the 1950s to some 25,000 today.
