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

Kepler Energy reveals plans for tidal energy scheme in Bristol Channel

With its large tidal range, Britain's Bristol Channel has a huge potential for generating tidal electric power. The problem is that, until now, schemes for tapping that power have required building dams and barrages so gigantic they would have given even the most wild-eyed Victorian engineer pause. As a more economical alternative, Kepler Energy has announced plans for a 30 MW tidal energy fence to be built in the Channel. With an estimated cost of £143 million (US$223 million), the underwater fence would be built in the water somewhere along the line between Aberthaw and Minehead and could be operational by 2021.Read More

European climate at mercy of retreating sea ice

An international team of scientists has found that retreating sea ice between the Atlantic and Arctic Oceans is linked to weakened air-sea heat exchange in the region. This, it warns, could result in a cooler climate in western Europe and an altered or slower Atlantic Meridional Overturning Circulation (AMOC), which would have knock-on effects for the Gulf Stream and consequently for the atmosphere.Read More

Researchers say Earth is entering a sixth mass extinction event

While there is still much conjecture about the causes of some mass extinctions, it is generally believed that they can occur when a biosphere under long-term stress is subjected to a short-term shock. In 1982, Jack Sepkoski and David M. Raup published a paper identifying five mass extinction events throughout Earth's history. Now a team of researchers claims that we are entering a sixth mass extinction event, which threatens our very existence.Read More

Hybrid road sweeper keeps air cleaner, too

A Swiss joint venture has developed a hybrid-electric powertrain for road sweepers that's said to consume half the energy of diesel-hydraulic vehicles and reduce emissions by more than 60 percent. The modular system can also be adapted to cleaner fuel types such as hydrogen. Read More
