Ultrashort-pulse fiber laser reaches unprecedented performance at Cornell

ITHACA, N.Y. – Cornell University researchers have engineered a new kind of environmentally-stable fiber laser that generates high-power ultrashort light pulses, opening new possibilities and applications for the fiber source. The fiber laser produced approximately 50-nJ and 40-fs pulses, which yield a peak power of one megawatt, an order of magnitude higher than that of […]

Transforming last night’s leftovers into green energy

ITHACA, N.Y. – In a classic tale of turning trash into treasure, two different processes soon may be the favored dynamic duo to turn food waste into green energy, according to a new Cornell University-led study. “Food waste should have a high value. We’re treating it as a resource, and we’re making marketable products out […]

WannaCry attack reveals two troubling ethical lapses

The WannaCry ransomware attack continued to spread this weekend. Authorities in Europe say it’s impacting more than 10,000 organizations and 200,000 people in 150 countries. The malware behind WannaCry was reported to have been stolen from the National Security Agency in April. Cornell University engineering professor Stephen Wicker has briefed the U.S. government on cyber […]

Trump dump of Paris climate deal bad for business

President Trump is delaying decision on the U.S. participation in the Paris climate accord, a deal brokered by Obama which Trump has repeatedly criticized. Natalie Mahowald a professor in Cornell University’s Department of Earth and Atmospheric Sciences, Faculty Director of Environment at the Atkinson Center for a Sustainable Future at Cornell University and an expert […]

VIDEO: New fabric coating protects your clothes, and the environment

Media Note: See a demonstration video and hear from professors Emmanuel Giannelis and Jintu Fan, at https://cornell.box.com/v/treatedfabric or on the Media Relations YouTube page. ITHACA, N.Y. – When you spill pasta sauce on your favorite shirt but there is no trace of it after being washed, you can thank oleophobicity, a resistance to oil commonly […]

Stabilizing molecule could pave way for lithium-air fuel cell

ITHACA, N.Y. – Lithium-oxygen fuel cells boast energy density levels comparable to fossil fuels and are thus seen as a promising candidate for future transportation-related energy needs. Several roadblocks stand in the way of realizing that vision, however. They include poor rechargeability, reduced efficiency due to high overpotentials (more charge energy than discharge energy) and […]

Did you catch that? Robot’s speed of light communication could protect you from danger

  Media Note: To view and download a “model” image of the technology, go to https://cornell.box.com/v/robotsurveillance.   ITHACA, N.Y. – Cornell University researchers are developing a system to enable teams of robots to share information as they move around, and if necessary, interpret what they see. This would allow the robots to conduct surveillance as […]

New privacy bill tilts power away from consumers

Congress recently approved a bill to overturn the nation’s strongest internet privacy protections. President Trump is expected to sign the bill into law this week. Cornell University engineering professor Stephen Wicker has briefed the U.S. government on cyber security, information technology and privacy concerns and is the author of “Cellular Convergence and the Death of […]
