Tropical groundwater resources resilient to climate change

Tropical groundwater may prove to be a climate-resilient source of freshwater in the tropics as intense rainfall favours the replenishment of these resources, according to a new study published in Environmental Research Letters. As climate observations show that global warming leads to fewer but more intense rainfalls, a clearer understanding of how these sources are replenished is crucial for developing […]

Russia has plans to nuke Earth-bound asteroids, if necessary

From 2012 to 2015, Russia researched ways of deflecting Earth-bound asteroids using nuclear weapons and came up with a best-case scenario. The Central Scientific Research Institute of Machine Building, an arm of Russia’s state-run Roscosmos space agency, worked on the asteroid problem with other countries (including the United States) in a program called NEOShield, which was largely funded by the […]

How “stop-and-frisk” backfires

Young people who are randomly stopped for questioning by the police—even if they’ve done nothing wrong—are more likely to engage in criminal behavior later than those who aren’t stopped, a new study has found. University of Missouri researchers say that “stop-and-frisk” programs intended to deter crime may actually create more criminals. Researchers followed 2,600 students for seven years and recorded […]

Painting the world white

Here’s a novel idea for putting the brakes on global warming: Ask everyone in the world to paint their roofs white. U.S. Energy Secretary Steven Chu raised the idea last week at a conference in London, noting that the proposal, first put forth by researchers at Lawrence Berkeley National Laboratory in California, would reflect enormous amounts of sunlight off the […]

Seabin – The Automated Marina Rubbish Collector

The Seabin marine waste collector shows how often the simplest solutions are the most effective. The rubbish collector, designed to float in marinas, inland waterways, residential lakes and harbors, collects floating debris and liquids by sucking water from the surface and letting if flow out through the bottom of the structure, trapping waste in a filter bag. The inventors have […]
