But Orts and a team of collaborators from Lapol, LLC, of Santa Barbara, Calif., hope to change that by making corn-derived plastics more heat-tolerant. Orts and Lapol co-investigators Allison Flynn and Lennard Torres are doing the work at the Agricultural Research Service (ARS) Western Regional Research Center in Albany, Calif., where Orts leads the Bioproduct Chemistry and Engineering Research Unit. ARS is USDA's principal intramural scientific research agency.
By boosting the bioplastics' heat tolerance, the collaboration—under way since 2007—may broaden the range of applications for which corn-derived plastics could be used as an alternative to petroleum-based plastics.
Corn-based plastics are made by fermenting corn sugar to produce lactic acid. The lactic acid is used to form polylactic acid, or PLA, a bioplastic. The Albany team is developing a product known as a heat-deflection temperature modifier that would be blended with PLA to make it more heat-tolerant.
The modifier is more than 90 percent corn-based and is fully biodegradable. There currently are no commercially available heat-deflection temperature modifiers for PLA, according to Randall L. Smith, chief operating officer at Lapol. ARS and Lapol are seeking a patent for the invention.

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
