Mantis Shrimp Key to Stronger Airplanes

April 24, 2014 7:00 am | by UC Riverside | Videos | Comments

Inspired by the fist-like club of a mantis shrimp, a team of researchers has developed a design structure for composite materials that is more impact resistant and tougher than the standard used in airplanes.


Gene Therapy May Improve Cochlear Implants

April 24, 2014 7:00 am | by Associated Press, Lauran Neergaard | News | Comments

Researchers are trying a novel way to boost the power of cochlear implants. They used the technology to beam gene therapy into the ears of deaf animals and found the combination improved hearing.


Scientists Watch Enormous Iceberg Drift

Triclosan, a common antibacterial compound in soaps and other products, spurred the growth of breast cancer cells in lab tests and mice.


Featured Report: Oil Spill Cleanup in Arctic Requires Increased Infrastructure

April 23, 2014 1:00 pm | by National Research Council | News | Comments

A changing climate is increasing the accessibility of U.S. Arctic waters to commercial activities such as shipping, oil and gas development and tourism. That’s raising concerns about the risk of oil spills. Now, a report says a full suite of proven oil response tools is needed to address potential oil spills in U.S. Arctic waters, but not all of them are readily available.


How to Avoid Fracking Industry Water Woes

April 23, 2014 12:03 pm | by ACS | News | Comments

Physicist Demonstrates How the OED Was Wrong

April 23, 2014 12:00 pm | by Queensland Univ. of Technology | News | Comments

In 2010, a physicist spotted a mistake in the prestigious Oxford English Dictionary that had gone unnoticed for 99 years. The OED incorrectly described atmospheric pressure, rather than gravity, as the operating force in a siphon. Now, he has proven the mistake by demonstrating the science of siphons.
