Researchers say Earth is entering a sixth mass extinction event

By - June 21, 2015 1 Picture

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.

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.

Study shows how the US could achieve 100 percent renewable energy by 2050

By - June 9, 2015 2 Pictures

A team of researchers led by Stanford University's professor Mark Z. Jacobson has produced an ambitious roadmap for converting the energy infrastructure of the US to run entirely on renewable energy in just 35 years. The study focuses on the wide-scale implementation of existing technologies such as wind, solar and geothermal solutions, claiming that the transition is both economically and technically possible within the given timeframe.

Coated polymer stack promises to keep your roof cool in summer

By - June 1, 2015 2 Pictures

Of all the scenarios you'd want to find yourself in a heatwave, being barefoot on a hot tin roof would be toward the bottom of the list. These exposed surfaces soak up sunlight to slowly but surely transform into corrugated hotplates, compounding the sweltering ambient temperatures and warming the living space below. But a team of Sydney-based scientists has developed a new material that's claimed capable of keeping a rooftop cooler than the air that surrounds it, saving energy and sweating residents in the process.

New model predicts significant Everest ice loss

By - May 27, 2015 1 Picture

A team of researchers from France, Nepal and the Netherlands has worked to produce a new model to predict the future changes in glaciers in the Everest region of the Himalayas. While the study, which was conducted by the European Geosciences Union (EGU), only represents an initial approximation of ice loss in the region, the model suggests that dramatic changes may be ahead.
