Naval Research Laboratory’s (NRL) benthic microbial fuel cell (BMFC) extracts electricity from the sea floor using the natural decomposition process of sediment. Most current scientific sensors in the marine environment are battery-powered, but the BMFC offers an attractive alternative to a...

Soldiers who have deployed in support of Operation Enduring Freedom, Operation Iraqi Freedom or Operation New Dawn, have the shared experience of being issued ballistic plates for their body armor that have been turned in by other soldiers after their combat tours. Part of ensuring plates are combat...

An envelope laced with ricin intended for the president of the United States was recently intercepted by law enforcement officials when protocols established for mail screenings revealed the threat of a biological weapon. Ricin is a highly toxic, naturally occurring protein found...

A team of researchers from Stanford University and the Department of Energy’s (DOE) SLAC National Accelerator Laboratory have made the first battery electrode that heals itself, opening a new and potentially commercially viable path for making the next generation of lithium ion batteries.

Scientists at the Weizmann Institute, Rehovot, Israel, have taken a quantum leap toward understanding the exciting phenomenon of superconductivity. They have created the world’s smallest SQUID, a Superconducting QUantum Interference Device, used to measure magnetic fields, breaking the world...

A team of researchers at Kansas State University, Manhattan, are developing improvements for astronauts' outerwear. The team, which includes electrical and computer engineering professors and more than a dozen students, envisions a future spacesuit that could monitor astronauts'...

Two firms are already planning prospecting missions to passing asteroids. Meteorites contain precious metals, including platinum and rhodium, but the presence of hydrogen and oxygen could also enable 'pit stops' to create fuel for Mars missions.

A single layer of tin atoms could be the world’s first material to conduct electricity with 100 percent efficiency at the temperatures that computer chips operate, according to a team of theoretical physicists led by researchers from the U.S. Department of Energy’s (DOE) SLAC National...

Although 3D printing — or direct digital manufacturing — has the potential to revolutionize various industries by providing faster, cheaper, and more accurate manufacturing options, fabrication time and the complexity of multimaterial objects have been a longtime hurdle to its widespread use in the...

Results from a recent study that looked at how battlefield-born vibrations, like those from blasts and heavy armored vehicles, for example, are leading research scientists to rethink military vehicle testing and evaluation methods that could also, eventually, improve automotive and...

Plasmas are a soup of charged particles in an electric field, and are normally found in stars and lightning bolts. With the use of high voltage equipment, very small plasmas can be used to manipulate fluid flows. In recent years, the development of devices known as plasma actuators has advanced the promise of...

During spring break the last five years, a University of Washington class has headed to the Nevada desert to launch rockets and learn more about the science and engineering involved. Sometimes, the launch would fail and a rocket smacked hard into the ground. This year, the session...

A bee and a jumbo jet: common sense would tell you that the tiny insect couldn't possibly cause any troubles for the massive airplane, right? Actually, no. Bees can cause trouble. When flying insects get in the way of an airplane's wing during takeoff or landing, it's not just the bugs...
