Atmotube personal pollution monitor tracks air quality on the go

Life in many of today's big cities unfortunately brings with it exposure to dense particle pollution. As a result, urban residents from Beijing, China to Santiago, Chile face serious health risks, such as heart and lung disease and premature death. A new US-based startup has developed a pocket-sized pollution monitor it hopes will serve as a warning system, by constantly assessing the environment while the user is on the go and alerting them when air quality drops to unacceptable levels.Read More

Claimed darkening of ice sheet could actually be down to aging satellite sensors

In recent years, satellite photos of Greenland's ice sheet have shown what appears to be a darkening of the ice's surface. A number of scientists have suggested that this could be due to settled soot particles from fossil fuel production and/or forest fires, and that their presence could result in accelerated melting of the ice. Now, however, researchers from Dartmouth College believe that the ice may still still be relatively clean, and that its darkness in the photos could just be due to faulty sensors on the satellites.Read More

Smartphones may soon detect air pollution

According to the World Health Organization, nitrogen dioxide (NO2)-based air pollution contributes to over 7 million deaths per year – children and the elderly are particularly at risk. Thanks to research being carried out at Australia's RMIT University, however, it may soon be possible to receive early warnings of dangerous NO2 levels in the air around you … via a sensor in your smartphone.Read More

New material created from orange peel cleans up mercury pollution

Since the beginning of the industrial age, mercury pollution has increased steadily in our environment, particularly in rivers and oceans. As a result, high-level predators in our waterways often contain very high levels of mercury, and eating fish containing this neurotoxin can lead to serious health issues. Now Australian scientists working at Flinders University have discovered a simple and efficient way to remove mercury from the environment by using a material made from recycled waste citrus peel.

Cleaner-burning cookstove creates its own flame-fanning electricity

While many of us may enjoy grilling food over an open fire, the fact is that cooking fires are a major source of health problems for millions of people in developing nations, who use them on a daily basis. The main problem is the smoke, which causes respiratory problems – not to mention air pollution. In an effort to address the problem, research group RTI International has developed a cook stove that burns cleaner … and that powers gadgets.Read More

Synthetic material mimics coral's ocean-cleaning attributes

Humanity's industrial processes have a huge impact on the and, releasing harmful substances such as mercury, arsenic and lead into the water. Chinese researchers are hoping that synthetic coral that mimics the ability of the real thing to collect harmful heavy metals from water could help in the clean up effort, with tests on the effectiveness of the aluminum oxide structure so far showing promising results.Read More
