Photos of the Day: Introducing supersonic passenger planes

March 18, 2014 9:23 am | by NASA | News | Comments

The level of concern over sonic boom annoyance became so significant that the Federal Aviation Administration prohibited domestic civil supersonic flight over land in 1973. This prohibition helped quiet the skies and reduce potential impacts on the environment. However, it also dashed hopes of introducing supersonic overland passenger service within U.S. airspace during the Concorde era.

Fighting antibiotic resistance with 'molecular drill bits'

March 17, 2014 12:41 pm | by EurekAlert! | News | Comments

In response to drug-resistant "superbugs" that send millions of people to hospitals around the world, scientists are building tiny, "molecular drill bits" that kill bacteria by bursting through their protective cell walls. They presented some of the latest developments on these drill bits, better known to scientists as antimicrobial peptides (AMPs).

Harnessing everyday motion to power mobile devices

March 17, 2014 12:13 pm | by EurekAlert! | News | Comments

Imagine powering your cell phone by simply walking around your office or rubbing it with the palm of your hand. Rather than plugging it into the wall, you become the power source. Researchers at the 247th National Meeting & Exposition of the American Chemical Society (ACS), the world's largest scientific society, presented these commercial possibilities and a unique vision for green energy.
