Student's six-foot water and solar-powered lens purifies polluted water
(Phys.org) —Water may appear to be an abundant resource, but in some parts of the world clean water is hard to come by.
Cause of global warming hiatus found deep in the Atlantic Ocean
Following rapid warming in the late 20th century, this century has so far seen surprisingly little increase in the average temperature at the Earth's surface. At first this was a blip, then a trend, then ...
Cutting emissions pays for itself, research shows
Lower rates of asthma and other health problems are frequently cited as benefits of policies aimed at cutting carbon emissions from sources like power plants and vehicles, because these policies also lead ...
The world's most polluting coal plants are identified
New research from the Stranded Assets Programme at the University of Oxford's Smith School of Enterprise and the Environment has identified the least efficient coal-fired power stations in the world.
Major breakthrough could help detoxify pollutants
Scientists at The University of Manchester hope a major breakthrough could lead to more effective methods for detoxifying dangerous pollutants like PCBs and dioxins. The result is a culmination of 15 years of research and ...
Climate change and air pollution will combine to curb food supplies
Many studies have shown the potential for global climate change to cut food supplies. But these studies have, for the most part, ignored the interactions between increasing temperature and air pollution—specifically ozone ...
Engineers develop new sensor to detect tiny individual nanoparticles
Nanoparticles, engineered materials about a billionth of a meter in size, are around us every day. Although they are tiny, they can benefit human health, as in some innovative early cancer treatments, but ...
Enviro-tracker is wearable for citizen monitoring
Solar dimming caused by air pollution increases river-flows
A study published in Nature Geoscience shows that air pollution has had a significant impact on the amount of water flowing through many rivers in the northern hemisphere.
A new approach in the search for extraterrestrial intelligence: targeting alien polluters
Humanity is on the threshold of being able to detect signs of alien life on other worlds. By studying exoplanet atmospheres, we can look for gases like oxygen and methane that only coexist if replenished ...
Depth of plastic pollution in oceans revealed
Wind and waves can mix buoyant ocean plastics throughout the water column, but most of their mass remains at the sea surface, according to research led by The University of Western Australia.
An up-close look at what air pollution is doing to your body
We are all aware that air pollution can be bad for our health – the World Health Organisation estimated that ambient air pollution caused 3.7 million premature deaths worldwide in 2012 – yet what exactly ...
New cheap NFC sensor can transmit information on hazardous chemicals, food spoilage to smartphone
MIT chemists have devised a new way to wirelessly detect hazardous gases and environmental pollutants, using a simple sensor that can be read by a smartphone.
Himalayan ice shows chemicals ban is working
A unique study of frozen ice cores from the Tibetan Himalayas has shown that international agreements on phasing out the use of toxic persistent organic pollutants are working.
