WEST LAFAYETTE, Ind. - Researchers have taken a step toward practical applications for "hyperbolic metamaterials," ultra-thin crystalline films that could bring optical advances including powerful microscopes, quantum computers and high-performance solar cells. New developments are reminiscent of advances that ushered in silicon chip technology, said Alexandra Boltasseva, a Purdue University associate professor of electrical and computer engineering.

New Analytical Technology Reveals 'Nanomechanical' Surface Traits
WEST LAFAYETTE, Ind. – A new research platform uses a laser to measure the "nanomechanical" properties of tiny structures undergoing stress and heating, an approach likely to yield insights to improve designs for microelectronics and batteries.
Purdue Ag Economists: Shale Oil 'Dividend' Could Pay for Smaller Carbon Footprint
WEST LAFAYETTE, Ind. - Unanticipated economic benefits from the shale oil and gas boom could help offset the costs of substantially reducing the U.S.'s carbon footprint, Purdue agricultural economists say. Wally Tyner and Farzad Taheripour estimate that shale technologies annually provide an extra $302 billion to the U.S. economy relative to 2007, a yearly "dividend" that could continue for at least the next two decades, Tyner said.
Cell Signaling Pathway Linked to Obesity, Type 2 Diabetes
WEST LAFAYETTE, Ind. - A Purdue University study shows that Notch signaling, a key biological pathway tied to development and cell communication, also plays an important role in the onset of obesity and Type 2 diabetes, a discovery that offers new targets for treatment.
Discovery Is Key to Metal Wear in Sliding Parts
WEST LAFAYETTE, Ind. – Researchers have discovered a previously unknown mechanism for wear in metals: a swirling, fluid-like microscopic behavior in a solid piece of metal sliding over another. The findings could be used to improve the durability of metal parts in numerous applications.
Spinach Could Lead to Alternative Energy More Powerful Than Popeye
WEST LAFAYETTE, Ind. — Spinach gave Popeye super strength, but it also holds the promise of a different power for a group of scientists: the ability to convert sunlight into a clean, efficient alternative fuel. Purdue University physicists are part of an international group using spinach to study the proteins involved in photosynthesis, the process by which plants convert the sun's energy into carbohydrates used to power cellular processes.
