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 of...

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...

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...

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...

Register today for NASA Tech Briefs' National Nano Engineering Conference (NNEC), the premier event focused on current and future developments in engineering innovations at the nanoscale. The event returns to Boston this year on November 12-13 at the Boston Colonnade Hotel, featuring the fourth annual Nano 50 Awards,...

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 could...

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.

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 are...

Yale University researchers have created a blueprint for artificial cells that are more powerful and efficient than the natural cells they mimic. The energy-generating artificial cells could one day power medical implants and provide a big advantage over battery-operated devices. The scientists began with the question of whether an...

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...

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 below...

Purdue University researchers have developed a method of using nanoparticles to help treat injured brain and spinal cord cells. A team led by Richard Borgens of the School of Veterinary Medicine's Center for Paralysis Research and Welden School of Biomedical Engineering coated silica nanoparticles with a polymer to target and...

A light-transmitting compound called (A)ZrPSe 6, where A can be potassium, rubidium, or cesium, has a difficult chemical structure that does not crystallize well. Scientists from the Argonne National Laboratory and Northwestern University were able to determine the structure of the compound using the uniquely...

Temp Tracker and Temp Tracker 12 ch (single-channel and 12-channel versions) programs are designed for use with an atomic gravity gradiometer. They support the stable operation of the injection-locked slave laser(s) in an autonomous regime. Due to changes of environmental conditions and...
