Research enhances enzyme that degrades plastic

Since it was discovered, the enzyme known as PETase has drawn a great deal of scientific interest for its capacity of digesting PET (polyethylene terephthalate).

Breaking metamaterial symmetry with reflected light

Optical activity—rotation of the polarization of light—is well known to occur within materials that differ from their mirror image. But what happens if this symmetry is broken by the direction of illumination rather than ...

Organic waste for sustainable batteries

A carbon-based active material produced from apple leftovers and a material of layered oxides might help reduce the costs of future energy storage systems. Both were found to have excellent electrochemical properties and ...

New 'designer carbon' boosts battery performance

Stanford University scientists have created a new carbon material that significantly boosts the performance of energy-storage technologies. Their results are featured on the cover of the journal ACS Central Science.

Devices designed to identify pathogens in food

Researchers at the National Polytechnic Institute (IPN) in Mexico have developed a technology capable of identifying pathogens in food and beverages. This technique could work in the restaurant industry as a biosensor to ...

Optical control of motor functions

MIT researchers have demonstrated a highly flexible neural probe made entirely of polymers that can both optically stimulate and record neural activity in a mouse spinal cord—a step toward developing prosthetic devices ...
