Sweet diesel: Discovery resurrects process to convert sugar directly to diesel

Posted: 07 Nov 2012 10:29 AM PST

Nearly 100 years ago, a chemist discovered that Clostridium bacteria efficiently ferment sugar or starch into alcohols and acetone. Cheap fossil fuels made the process commercially unviable, but it is being resurrected by chemists and chemical engineers to feed a catalytic reaction that produces a fuel that looks and acts just like diesel. The simple process produces a fuel with more energy content than ethanol, and could help replace nonrenewable transportation fuels.

Quantum kisses change the color of nothing: New ways to measure the world at the scale of single atoms and molecules

Even empty gaps have a color. Now scientists have shown that quantum jumps of electrons can change the color of gaps between nano-sized balls of gold. The new results set a fundamental quantum limit on how tightly light can be trapped.

When it comes to imaging, every single photon counts if there is barely any available light. This is the point where the latest technologies often reach their limits. Researchers have now developed a diode that can read photons faster than ever before.
