Army Plans To Remove Tons Of Toxins From Lethal Rounds

An enemy convoy transporting a supply of fuel rumbles across the desert floor, an ideal target for armor-piercing incendiary projectiles. These projectiles are most useful for "after-armor effects," such as an incandescent flash immediately after penetrating a hard target. The resulting...

Army extends Global Information Grid Network To Company Level

As the U.S. mission in Afghanistan changes and forces conduct more dispersed operations, new tactical communications equipment for vehicles at the company level will help extend the network over vast distances to keep soldiers connected and commanders informed.

Researchers Develop Next-Generation Electronic Warfare Tools

When U.S pilots encounter enemy air defenses, onboard electronic warfare (EW) systems protect them by interfering with incoming radar signals – a technique known as electronic attack (EA) or jamming. Conversely, electronic protection (EP) technology prevents hostile forces from using...

NASA’s post-Shuttle era has demonstrated that the agency continues to achieve amazing engineering feats – not the least of which is the Mars rover Curiosity, which has met the main goal of its 2-year...

Smallest-Ever Autopilot for Micro Aerial Vehicles

Researchers at the Netherlands' Delft University of Technology (TU Delft) have designed, built, and tested what they say is the world's smallest autopilot for small unmanned aircraft.

NASA's Asteroid Redirect Mission: A Conceptual Animation

NASA has released this conceptual animation depicting the agency's planned mission to find, capture, redirect, and study a near-Earth asteroid.

Telescope Mirror Offers Sharpest Photos of Night Sky

Astronomers at the University of Arizona, the Arcetri Observatory near Florence, Italy, and the Carnegie Observatory have developed a new type of camera that allows scientists to take sharper images of the night sky than ever before, and in visible light. Using a telescope mirror that...

Question of the Week
Are 'Virtual Receptionists' a Good Idea?

The London borough of Brent is using a virtual receptionist, or hologram, to greet visitors in its new civic center. The hologram responds to questions about locations in the building, such as where to register births or where to head to apply for a marriage certificate. The virtual employee will be...

Assembling Big Structures Out of Small, Interlocking Composite Components

MIT researchers have developed a lightweight structure whose tiny blocks can be snapped together much like the bricks of a child’s construction toy. The new material, the researchers say, could revolutionize the assembly of airplanes, spacecraft, and even larger...

New Tests Cool Turbine Blades and Improve Engines

Iowa State University’s Hui Hu and Blake Johnsonare developing new technologies to accurately test and improve engine cooling strategies. Their current focus is to improve the turbine blades spun by the engine’s exhaust. Those blades at the back of the engine drive front blades that force...

Army Collaboration Leads to New Rocket Propulsion Technology

A team of Army researchers developed a new gel-propellant engine called the vortex engine. Michael Nusca Ph.D., a researcher in Army Research Laboratory’s Propulsion Science Branch at Aberdeen Proving Ground, explained the new technology.

Astronomers Obtain Close-Up View of the Drama of Starbirth

Young stars are violent objects — ejecting material at speeds as high as one million kilometers per hour. When this material crashes into the surrounding gas it glows, creating what is called a Herbig-Haro object.

Rechargeable Battery Design Improves Energy Storage

MIT researchers have engineered a new rechargeable flow battery that does not rely on expensive membranes to generate and store electricity. The device, they say, may one day enable cheaper, large-scale energy storage.

Researchers Teleport Information by Electronic Circuit

Physicists at ETH Zurich have for the first time successfully teleported information in a solid state system. The researchers used a device similar to a conventional computer chip.

Question of the Week
Is a Hyperloop on the Way?

Last week, entrepreneur Elon Musk unveiled a transportation concept that he said could whisk passengers the nearly 400 miles between Los Angeles and San Francisco in 30 minutes. The theoretical Hyperloop would consist of carlike capsules traveling at more than 700 mph through enclosed tubes. The capsules, which would...
