Longer battery life for electric locomotive
Norfolk Southern Railway No. 999 is the first all-electric, battery-powered locomotive in the United States. But when one of the thousand lead-acid batteries that power it dies, the locomotive shuts down.
Record-setting p-type transistor Design
New design for a basic component of all computer chips boasts the highest 'carry mobility' yet measured
Turning smartphones into secure and versatile keys
It's already possible to open doors using an app but we are a long way from seeing widespread acceptance of this in the market. Now, researchers have developed a piece of software that will make the technology even more secure and versatile.
Two Mastered CT Scans reveal Chemo-Killing of Liver Tumors in Real Time
Using two successive pairs of specialized CT scans, a team of Johns Hopkins and Dutch radiologists has produced real-time images of liver tumors dying from direct injection of anticancer drugs into the tumors and their surrounding blood vessels.
New '4-D' transistor is preview of future computers
WEST LAFAYETTE, Ind. - A new type of transistor shaped like a Christmas tree has arrived just in time for the holidays, but the prototype won't be nestled under the tree along with the other gifts.
