by Fintan Burke Tracking the brain’s reaction to virtual-reality-simulated threats such as falling rocks and an under-researched fear reduction strategy may provide better ways of treating anxiety disorders and preventing relapses. Hippocrates described them as ‘masses of terrors,’ while French physicians in the 18th century labelled them as ‘vapours’ and ‘melancholia.’ Nowadays we know that panic … Read more

Food waste, garden cuttings, manure, and even human sewage can be turned into solid biocoal for energy generation, and, if scaled up, could help match the industrial demand for carbon with the need to get rid of organic waste and reduce greenhouse gas emissions.  Europe has a biowaste problem. Rather than using the carbon-rich material … Read more
