Aerosols, tiny solid and liquid particles suspended in the atmosphere, impact the environment by affecting air quality and alter the Earth’s radiative balance by either scattering or absorbing sunlight to varying degrees. What impact does climate change, induced by greenhouse gases (GHGs), have on the aerosol “burden”–the total mass of aerosols in a vertical column of air? Past research done […]

The number of juveniles in the nation’s criminal justice system has been in decline for years. California and New York have closed some of their largest and most troubled juvenile detention facilities. Missouri has recently been credited with doing a better job of caring for its most troubled children, further limiting the state’s population of teens in punitive settings. But […]

1. The first confirmed sighting of the continent was in 1820. 2. Explorers first reached the South Pole in 1911. 3. Because Antarctica lies in the southern hemisphere, seasons there are the opposite of seasons in the north — summer runs from October to February and winter covers the remainder of the year. 4. Antarctica is the coldest continent; temperatures […]

The amount of CO2 is increasing all the time – we just passed a landmark 400 parts per million concentration of atmospheric CO2, up from around 280ppm before the industrial revolution. That’s a 42.8% increase. A tiny amount of CO2 and other greenhouse gases, like methane and water vapor, keep the Earth’s surface 30°Celsius (54°F) warmer than it would be […]

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 […]

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 […]

The VEST is the brainchild of Dr. David Eagleman, a neuroscientist at the Baylor College of Medicine in Houston, Texas. He designed the device based on the principles of sensory substitution, the theory that scientists can transmit data gathered by the brain using one sense, and transfer it to another sense. In this case, the VEST translates touch into sound. […]

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 […]

Massive icebergs more than 18km long give Giant boost for south polar waters by feeding vital nutrients into the Southern Ocean and helping to increase its carbon storage capacity. LONDON, January, 2016 – British scientists have identified the monsters that fertilize the Southern Ocean and help remove carbon dioxide from the atmosphere. Giant icebergs drifting northwards could be responsible for storing up […]

Coffee is one of the most popular beverages in the world for lots of reasons, including that it gives people a pleasant lift in the morning. New research shows that it also helps their memory. Researchers had 160 people who were not regular coffee drinkers look at pictures of objects; five minutes later they gave them either a placebo or […]
