Scientists Create 99.9 Percent Pure Gold in Lab

October 5, 2012

Two researchers at Michigan State University say they have discovered a way to make 99-percent pure gold. The process, which they call microbial alchemy, involves combining the bacterium Cupriavidus metallidurans with gold chloride. But don't get too excited. The researchers say it's likely too expensive to produce on a large scale.

NASA Claims Spaceships Traveling Faster Than Light May Be Possible

Buzz60 (Sep. 18, 2012) — Scientists at NASA think that bending space and time could be possible. This would allow spaceships to travel faster than the speed of lite and thus zip between different solar systems. Devices used in Star Trek might not be that far off as NASA scientists have begun testing their designs and theories in the lab.

Tax Break for UK Shale Industry

Reuters (July 19, 2013) — The British government is hoping to create the world's most generous shale tax regime, slashing the tax on income on shale production from 62 percent to 30 percent. It's hoped the incentive will help lower energy bills by reducing the country's reliance on natural gas imports. As Kirsty Basset reports, the government is also insisting on benefits for affected communities to placate environmental concerns about fracking.

The Physics Behind Oracle's America's Cup Victory

The Physics Behind Oracle's America's Cup Victory (Oct. 4, 2013) — The Physics Behind Oracle's America's Cup Victory California Academy of Sciences - African Hall Why go fast? Compared to moving slowly, the advantages seem obvious: find food first, forage more widely, and escape more rapidly! But, in the water, being speedier incurs huge energetic costs, with moving a little bit faster skyrocketing the amount of fuel you need. This trade-off between speed and energy propels the evolutionary race for fish, robots, or sailboats: you have to find ways to go faster with ever-greater efficiency. Over generations, the evolutionary race can produce biological and engineering surprises: distantly related fish and boat hulls that have similar streamlined shapes, materials and construction techniques that manage to both stiffen and lighten bodies and hulls, specialization of propulsive systems, and constraints on making turns and tight maneuvers. While the evolutionary processes employed by nature and engineers are similar, there are important differences in how fish or boats are built. For both kinds of designers, the laws of evolution and physics interact to create and constrain the drive for speed. Dr Long will discuss how robotics research lab studies fast fish! A book signing will follow the talk for Dr. Long's latest book titled Darwin's Devices: What Evolving Robots Can Teach Us About the History of Life and the Future of Technology.
