A new technique has been used to turn ordinary metals into “metallic wood” with a greatly improved strength-to-weight ratio. By manipulating materials at the atomic scale, scientists from the University of Pennsylvania’s School of Engineering and Applied Science, the University of Illinois at Urbana–Champaign, and the University of Cambridge claim to have created a sheet of nickel that is as strong as titanium, but up to five times lighter.
Beginning with the principles of the Stirling engine, SoundEnergy’s THEAC thermal acoustic engine takes heat – either industrial waste heat or solar heat – and turns it into powerful cooling without requiring any other power source. This completely renewable technology could prove highly disruptive.

A cure for cancer? Israeli scientists say they think they found one
Genetically modified bacteria could be used to treat liver and bowel diseases by mopping up toxins inside the gut.
Researchers tested the groundbreaking technique by creating a common strain of bacteria mop up excess ammonia in the body.
High levels of the chemical can be fatal for people with liver damage and rare genetic disorders.
Probably ever since bicycles were first invented, people have been looking for alternatives to the traditional approach of pedalling in circles. Los Angeles-based inventor Rodger Parker has utilized one such alternative in his NuBike, which he claims is more efficient than a chain-drive bike.
