New Way to Model Multicore Chips Discovered

Most computer chips today have anywhere from four to 10 separate cores, which can work in parallel, increasing the chips’ efficiency. But the chips of the future are likely to have hundreds or even thousands of cores. For chip designers, predicting how these massively multicore chips will behave is...

Can Electrical Circuits Talk to Single Atoms?

If a practical quantum computer is ever to be realized, conventional electronic devices will have to interface with the delicate quantum systems such as atoms or ions in traps or wisps of magnetism near superconducting sensors. A recent paper in the journal Physical Review Letters, written by...

Researchers Create Non-Toxic, Rust-Proofing Steel

University at Buffalo researchers are making significant progress on rust-proofing steel, using a graphene-based composite that could serve as a nontoxic alternative to coatings that contain hexavalent chromium, a probable carcinogen.

In the scientists' first experiments, pieces of steel coated...

NASA Team Tests Vehicle-Descent Technologies

In what will be the first of four high-altitude balloon flights to begin in the summer of 2013, technologists at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Calif., and Wallops Flight Facility in Wallops Island, Va., are preparing to test new deceleration devices. The devices could replace...

Question of the Week
Will these types of "private space station" boost space tourism?

Rather than participate in fly-by suborbital flights, which are being offered by companies like Virgin Galactic, SpaceX Corp. has teamed up with Bigelow Aerospace to offer an experience in a microgravity living environment. The plan, laid out in a jointly issued news release, calls...

Scientists Develop Simulations of Blood Function

A team of biomedical engineers and hematologists at the University of Pennsylvania has made large-scale, patient-specific simulations of blood function under the flow conditions found in blood vessels, using robots to run hundreds of tests on human platelets responding to combinations of...

Airborne Radar is Readied for Missile Defense Testing

A new air defense radar system is undergoing testing on the White Sands Missile Range to prepare it for later integrated testing with the Navy this fall. The Joint Land Attack Cruise Missile Defense Elevated Netted Sensor System (JLENS) is an advanced radar system intended for use by the...

Research Teams Join to Help Reduce Jet Noise

The deafening roar of supersonic aircraft can cause hearing damage to sailors and Marines on flight decks, so the Office of Naval Research (ONR) is funding a new project to help reduce jet noise. According to the ONR, the noise problem falls into two categories: noise exposure on the flight deck, and...

NASA Will Use Cereal and Crayons to Test Jet Engine Sensors

NASA engineers will be tossing crayons and cereal into jet engines in a test of new aircraft engine health monitoring technology designed to provide early warning of engine problems, including the destructive effect of volcanic ash.

Carbon Nanotube Sponge Aids in Oil Spill Cleanup

A carbon nanotube sponge developed with help from ORNL researchers holds potential as an aid for oil spill cleanup. Simulations at ORNL explained how the addition of boron atoms encouraged the formation of so-called "elbow" junctions that help the nanotubes grow into a 3-D network.


Question of the Week
Will these holographic tools, and similar technologies, catch on?

This week's INSIDER story demonstrated a Star Trek-like, human-scale 3D videoconferencing pod  that allows people in different locations to video conference as if they are standing in front of each other.

Assembly Errors Are Quickly Identified With New Testing Technology

Today‘s cars are increasingly custom-built. One customer might want electric windows and heated door mirrors, while another is satisfied with the minimum basic equipment. The situation with aircraft is no different: each airline is looking for different interior finishes. Yet...

Seismic Tests of Full-Scale Building Predict Earthquake Damage

What happens when you put a fully equipped five-story building — which includes an intensive care unit, a surgery suite, piping and air conditioning, fire barriers, and even a working elevator — through a series of high-intensity earthquakes?

Miniature Sandia Sensors May Advance Climate Studies

An air sampler the size of an earplug is expected to cheaply and easily collect atmospheric samples to improve computer climate models. Developed by Sandia National Laboratories, the design employs a commonly used alloy to house an inexpensive microvalve situated above the sample chamber.
