Adidas uses ocean trash to make footwear – and a statement

The world’s oceans are in peril due to a combination of pollution, overfishing and climate change. Recently, the Alfred-Wegener-Institut, a German center for polar and marine research, sent out a strong warning about fundamental changes that are occurring in those ecosystems. But awareness is growing and the fight to preserve the oceans has found an ally in Adidas, which has teamed with conservation group Parley for the Oceans to create footwear made with trash harvested from the ocean.Read More

Ocean Cleanup concept to become a reality next year

A concept designed to rid the oceans of plastic waste is to become a reality next year. Boyan's Slat's Ocean Cleanup system is expected to be deployed in the second quarter of 2016 in the waters between Japan and South Korea. It will be the longest floating structure ever deployed in the ocean.Read More

ESA's Sentinel-2A satellite arrives in French Guiana ahead of launch

ESA's Sentinel-2A satellite has arrived safely in French Guiana, ahead of its June 12 launch atop a Vega rocket. It was carried in the belly of an enormous Russian-made Antonov cargo plane, and protected within a specially-constructed air conditioned habitat. Once operational, the satellite will represent a cornerstone of the agency's Copernicus program, which is striving to revolutionize how we observe and understand our environment, and how we may be able to tackle the detrimental effects of climate change.

Dyson unveils next-generation air purifier

Not content with vacuums and fans, Dyson is expanding into the realm of air purification with its Pure Cool purifier fan, which was unveiled today. Building on the company's Air Multiplier technology, it's designed to capture ultrafine particles, which are a major component of air pollution. To learn more, Gizmag talked to Dyson engineer Robert Green. Read More

Gold and other valuable metals may be harvested from sewage

Mining operations tend not be very good for the environment, nor does the disposal of treated solid waste that still contains potentially-toxic metals. Now, however, scientists are looking into taking that waste and harvesting its trace amounts of metals such as gold, silver and platinum. Doing so could ultimately reduce the need for mining and decrease the amount of metals entering the environment, while also turning sewage into a source of revenue. Read More

Speck monitors your home's air quality

Monitoring the level of particulates in the air inside the home can be a life-saver for people with health issues. A new personal air pollution monitor promises a more precise alternative, empowering users to take measures to mitigate and eliminate those tiny particles. Developed at Carnegie Mellon University Robotics Institute, Speck was presented at the SXSW Interactive Festival in Austin, Texas, that took place between March 13 and 17. Read More

ROV assesses thickness of oil slicks from underneath

When people are attempting to clean up oil spills at sea, one of the key things they need to know is the amount of oil that's been spilled – among other things, this will determine the amount of dispersant or other agents that are used. In order to make that process easier and more accurate, scientists from the Virginia Institute of Marine Science have developed a remotely operated vehicle (ROV) that does the job by measuring the thickness of oil slicks from below the surface.

New material promises more efficient carbon capture

We've already seen a number of technologies developed for capturing carbon dioxide emissions from smokestacks or other sources, but many of them have a limitation – in order to reclaim the captured CO2 for disposal, a considerable amount of energy is needed. Now, however, scientists at the University of California, Berkeley have developed a new carbon-capture material that requires far less energy in order to give up its payload. Read More

Low-cost air filter could help Beijing breathe easy

Material scientists at Stanford University have developed a highly effective semitransparent air filter that can collect 99 percent of the very small PM2.5 particles, considered the most harmful to the human respiratory tract. The low-cost filters, which don’t require power to function, could be used to build better protective facemasks, window screens, filtration systems in hospitals, and perhaps even to reduce pollution from cars and industrial smoke stacks.
