The probe, made of...

Plasmonic Lenses That 'Fly'

Engineers at the University of California at Berkeley, are reporting a new way of creating computer chips that could revitalize optical lithography, the dominant patterning technique in integrated circuits manufacturing. The researchers were able to create line patterns only 80 nanometers wide at speeds up to 12...

Disaster Response

Researchers at the Georgia Tech Research Institute (GTRI) have developed a low- cost, high-resolution imaging system that can be attached to a helicopter to create a complete and detailed picture of an area devastated by a hurricane or other natural disaster. The resulting visual information can be used to estimate the number...

Cosmic Lens

Astronomers at the California Institute of Technology and their colleagues have been able to observe a young star-forming galaxy as it appeared only two billion years after the Big Bang and determine how the galaxy may eventually evolve to become a system like our own Milky Way. The team made their observations by coupling two...

Seismic Simulations

For the first time, seismic signals that precede a volcanic eruption have been simulated and visualized in 3D under controlled pressure conditions in a laboratory. The ability to conduct such simulations will better equip municipal authorities in volcanic hot spots around the world in knowing when to alert people. Nearly 500...

Protein Highlighters

Biochemists Lila Gierasch and Beena Krishnan at the University of Massachusetts Amherst have found a way to slip a fluorescent marker into one of a cell's molecular machines so it lights up when it has formed the proper shape to carry out the cell's "work orders." The new technique should allow labeling of correctly folded...

MRI And Body Temperature

Duke University chemists say they have developed a new way to measure temperature changes inside the body with unprecedented precision, by correcting a subtle error in the original theory underlying Magnetic Resonance Imaging (MRI). The technique could improve clinical applications of hyperthermia against cancer, and...

Current Attractions

Each month, NTB highlights tech briefs related to a particular area of technology in a special section called Technology Focus. Here are some of the technologies featured in the October issue focus on Sensors.

T-Ray Camera

A terahertz version of the single-pixel camera developed by Rice University researchers could lead to breakthrough technologies in security, telecom, signal processing, and medicine. The researchers replaced expensive, multi-pixel sensor arrays used in current terahertz imaging systems with a single sensor. Two keys to the system...

Powerhouse Cells

The scientists began with the question of...

Hydrogen Sensor

Researchers at the National Institute of Standards and Technology and Colorado School of Mines have developed a prototype sensor that quickly detects very small amounts of hydrogen accumulation in coated pipeline steel. Hydrogen can cause gradual embrittlement in conventional pipelines by slowly diffusing into the metal. The new...

Microwaving Mars and the Moon

Research conducted by material scientists may lead to the ability to extract water from the Moon and possibly Mars by shooting microwave beams into their surface, according to Bill Kaukler, Associate Research Professor at the University of Alabama in Huntsville. The Phoenix Mars lander scratched just two inches...
