The tiny freshwater polyp Hydra is a remarkable creature. It does not show any signs of aging and appears to be immortal due to the fact that it contains stem cells capable of continuous proliferation. Researchers from Kiel University have examined this phenomenon and uncovered an important link to the aging process in humans that could lead to the development of advanced rejuvenation therapies.  Read More

Systems that convert kinetic energy into electric energy have made great strides in recent times, from mobile phone charging bicycle dynamos to tiles that turn footsteps into electrical energy. Recently researchers at Georgia Institute of Technology have come up with what they believe is a more efficient approach – a self-charging power cell that directly converts mechanical energy to chemical energy and stores the power for release as an electrical current.  Read More

Australian scientists have developed a promising new approach to hydrogen storage

Scientists at the University of New South Wales (UNSW), Australia, are developing a novel way to store hydrogen that could help turn it into a viable portable fuel source. The research centers on using synthesized nanoparticles of the compound sodium borohydride (NaBH4 for those who love chemistry), which when encased inside nickel shells exhibits surprising and practical storage properties including the ability to reabsorb hydrogen and release it at much lower temperatures than previously observed, making it an attractive proposition for transport applications.  Read More

The Aeroscraft uses a suite of new mechanical and aerospace technologies

The dirigible airship, the oddball aircraft of another era, is making a comeback. California-based Aeros Corporation has created a prototype of its new breed of variable buoyancy aircraft and expects the vehicle to be finished before the end of 2012. With its new cargo handling technology, minimum fuel consumption, vertical take-off and landing features and point to point delivery, the Aeroscraft platform promises to revolutionize airship technology.  Read More
