Quantum computer RAM blueprints

Three physicists in Italy and the US have proposed a method for retrieving quantum information from memory that should make total quantum recall more reliable. A quantum computer uses not bits but qubits, which can be a blend of 0 and 1 – a quantum superposition of the two states. Therefore, in quantum RAM, the …

Rocket powered mechanical arm, ten times power of commercial arms

We are getting closer to cyborgs that are as strong and as fast as people. The prototype rocket powered mechanical arm can lift (curl) about 20 to 25 pounds – three to four times more than current commercial arms – and can do so three to four times faster. “That means it has about 10 …

The Global Boom in coal

The world is building a lot of coal-fired power to go with all of the coal-fired power it already has. This is horrible because air pollution from coal kills more than one million people every year. We need to use all other means to reduce the increase in coal usage, this means more nuclear as …

Bacteria resistant artificial skin

Skin cells genetically engineered to be resistant to bacteria could reduce infections and improve chances of survival among burn victims. A patient’s skin cells, genetically modified and grown in a test tube, could provide the next generation of artificial skin. As a first step in creating such replacement skin, scientists in Cincinnati have engineered bacteria-resistant …
