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...

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...

Researchers modeling how changes in air flow patterns affect wind turbine output power have found that the wind can supply energy from an unexpected direction: below. The researchers introduced a mathematical way to measure changes in the flow that gives a more accurate representation of the...

Solar panel modules must fulfill certain standards to be approved for operation. This involves exposing them to high temperatures and high mechanical loading. However, the results only predict something about the robustness of a brand-new sample with respect to extreme, short-term loading....

NASA-developed computer software could help aircraft operators save time and fuel by allowing technology in the cockpit to help determine the most efficient flight paths while planes are in the air - in traffic - en route to their destinations.A concept called Traffic Aware Strategic Aircrew Requests, or...

Stanford researchers have developed an inexpensive device that uses light to split water into oxygen and clean-burning hydrogen. The goal is to supplement solar cells with hydrogen-powered fuel cells that can generate electricity when the sun isn't shining or demand is high.Two semiconducting electrodes...

A San Francisco startup introduced an all-in-one card, called Coin, meant to store financial information from every other card carried in a wallet. The device, available for preorder, includes a magnetic strip that can change depending on what card one wants to use. What do you think? Would you use an all-in-one...

Solar cells that produce electricity 24/7, not just when the sun is shining, or mobile phones with built-in power cells that recharge in seconds and work for weeks between charges. These are just two of the possibilities raised by a novel supercapacitor design invented by material scientists at...

Researchers at the University of California, San Diego report a breakthrough in technology that could pave the way for digital systems to record, store, edit and replay information in a dimension that goes beyond what we can see or hear, namely touch. “Touch was largely bypassed by the digital...

Researchers at NJIT have developed a flexible battery made with carbon nanotubes that could potentially power electronic devices with flexible displays.Electronic manufacturers are now making flexible organic light-emitting diode (OLED) displays, a pioneering technology that allow devices such as cell phones,...

MIT researchers have come up with a way to cool hot surfaces more effectively by keeping droplets from bouncing. Their solution: Decorate the surface with tiny structures and then coat it with particles about 100 times smaller. Using that approach, they produced textured surfaces that...
