Can You Meditate Your Way To A Bigger Brain?

Meditate your way to a bigger brain 

Push-ups, crunches and gyms are fine for building bigger muscles and stronger bones. But can you meditate your way to a bigger brain?

The answer is yes, as a new study has established that certain regions in the brains of those meditating long-term were larger than in a similar group.

Wind powered transportation is nothing new to this planet. While it has remained on the lakes and oceans for the most part, there are a few people out there who have brought it onto dry land. One such person, Richard Jenkins, has taken wind power to a new level by breaking the land speed record for a wind powered vehicle.

Platinum-Free Fuel Cells Eliminates Need For Expensive Catalysts

Platinum-Free Fuel Cells Eliminates Need For Expensive Catalysts 

 A new polymer, shown in powdered form, can be used to make stable fuel-cell membranes that conduct negatively charged ions.

Fuel cells are, in principle, the most efficient way to convert hydrogen fuel into electricity. But they require expensive catalysts such as platinum to split hydrogen into ions and electrical current. Cheaper metals simply can’t withstand the harsh acidic environment of the fuel cell. Now researchers in China have developed a fuel cell that uses a new membrane material to operate in alkaline conditions, eliminating the need for an expensive catalyst. The power output of the new prototype, which uses nickel as a catalyst, is still relatively low, but it provides a first demonstration of a potentially much less expensive fuel cell.

Space Elevator and the Controversial ‘Wobble’ Problem

 Space Elevator and the Controversial ‘Wobble’ Problem

If an elevator stretching from Earth into space could ever be built, it could slash the cost of space travel. But a controversial new study suggests that building and maintaining one would be an even bigger challenge than previously thought, because it would need to include built-in thrusters to stabilize itself against dangerous vibrations.
