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.

Trees trained to grow into furniture

By - June 2, 2015 36 Pictures
Much of our furniture is made from timber. The wood to make that furniture has to be harvested from a felled tree which is then milled, sawed, planed, sanded, put back together with glue and screws, and finished. Wouldn't it be easier to avoid most of these steps and simply coax a tree to grow into a piece of furniture? That way, it would be one-piece, inherently strong, and could potentially last many years longer than assembled furniture. Gavin Munro thought this too, and about a decade ago set about achieving this goal. He now creates furniture by cajoling trees to grow into one-piece items that are not only inherently practical, they are also eminently beautiful. Read More

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

By - April 27, 2015 2 Pictures
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.

New heat-recovery system makes Stanford one of world’s most energy-efficient uni's

By - April 26, 2015 7 Pictures
At Stanford University in California, it’s normally the Nobel-winning researchers who make the news. But with the commissioning of a novel renewable energy system, the campus’s humble heating and cooling system has grabbed some headlines. Using a first-of-its-kind heat recovery system, and drawing a substantial percentage of its electricity from solar, the university is greening up its operations in a move that will see greenhouse gas emissions cut by 68 percent and fossil fuel use cut by 65 percent.

Audi just created diesel fuel from air and water

By - April 26, 2015 7 Pictures
Audi is looking to fuel the future without fossil fuels. One of the company's pilot plants in Germany has just produced the first batches of a synthetic diesel made using only water and air. The company's pilot plant, which is operated by German startup Sunfire, produced its first batches of the "e-diesel" this month. German Federal Minister of Education and Research Johanna Wanka put a few liters of the fuel in her work car, an Audi A8, to commemorate the accomplishment. Read More
