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

New production process makes PLA bioplastic cheaper and greener

Polylactic acid (PLA) is a biodegradable bioplastic that is already used to produce a variety of everyday items, such as cups, trays, bowls and vegetable wrapping foil. Unfortunately, the current PLA production process is expensive and produces waste. Researchers at the KU Leuven Centre for Surface Chemistry and Catalysis in Belgium have now developed a new production technique that is cheaper and greener and makes PLA a more attractive alternative to petroleum-based plastics.Read More

Plastic road surface might be streets ahead of asphalt

Asphalt covers more than 94 percent of the paved streets in the US, but have we gone down the wrong road with our choice of building material? Dutch firm VolkerWessels thinks so and has unveiled plans for roads crafted from recycled plastic, claiming the approach would significantly cut construction and maintenance time, as well as extend their expected lifespan.Read More

Study suggests volcanic eruptions behind pause in climate change

Over the last few years, many possible explanations have been bandied about for the so-called pause in climate change, a plateau in global surface air temperatures that is out of step with rising greenhouse gas concentrations. But now an international research effort is laying responsibility at the feet of volcanic eruptions, whose particles it has found reflect twice as much solar radiation as previously believed, serving to temporarily cool the planet in the face of rising CO2 emissions.Read More

Azura wave energy system deployed in Hawaii

Although wave energy-harvesting systems are often just presented as concepts that may someday see actual use, one was recently deployed in Hawaii to provide power to the municipal grid. Built by Northwest Energy Innovations, the Azura device will remain in operation for a 12-month assessment period, with an eye toward eventual commercialization.Read More

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

Atomic clocks could be used to monitor volcanoes and predict eruptions

If you've ever been to Yellowstone National Park in Wyoming, you may have been aware of two things; its magnificent grandeur, and the fact that it's an active supervolcano that, if it ever erupted again, would be worst event to hit the Earth since the dinosaur-killing asteroid. To help keep an eye out for this and similar events, a team at the University of Zurich have developed a means of monitoring volcanic events using atomic clocks.Read More
