The response of tumors to anticancer drugs has been observed in real-time, 3D images using technology developed at Purdue University. The new digital holographic imaging system uses a laser and a charged couple device (CCD) to see inside tumor cells. The instrument also may have applications in drug development and medical...

Lightweight, High-Performance Propeller/Rotor/Wind Turbine Blade The turbine blade features a much lighter, more efficient, less expensive, and entirely new structural design. Other advantages offered bythis technology include increased performance, lower noise, decreased maintenance time and expense, and optimized...

A technology for monitoring protein growth -- developed in part through NASA Small Business Innovation Research (SBIR) funding from Marshall Space Flight Center -- is noninvasive, nondestructive, rapid, and more cost effective than x-ray analysis. The partner for this SBIR, Photon-X, Inc. (Huntsville, AL), developed spatial-phase...

Researchers at the Georgia Institute of Technology have created a new class of gas sensors using a chemical process that converts the silica (silicon dioxide) found in the shells of diatoms into the semiconductor material silicon. Silicon is normally produced from silica at temperatures well above the silicon melting point...

University of Wisconsin-Madison researchers have come one step closer to making fusion energy possible by showing that their magnetic plasma chamber, called a stellarator, can overcome a major barrier in plasma research by retaining the needed temperature for fusion to be possible. Past stellarators lose too much energy to reach the...

A disclosed technology allows a factory-installed seatbelt to be tightened from gentle to extreme. The seatbelt works like an aircraft seat belt: when tightened, it stays tight.View this technology here. A technology has been made available improving how safely children are strapped in their safety seats. View this...

Researchers at the Dana-Farber Cancer Institute (Boston, MA) have found that the p53 protein, known to guard against cancer-causing DNA damage, provides an entirely different level of cancer protection: by prompting the skin to tan in response to ultraviolet light from the sun, p53 deters the development of melanoma skin cancer....

Medical researches at Information Society Technologies (Brussels, Belgium) are developing the IntelliDrug controlled drug delivery system, where medication is stored and released from an implanted tooth. The fake tooth is a micro-system comprising of a medication reservoir and release mechanism, a built-in intelligence, micro- sensors,...

Printable Biosensor for On-Site, Online Measurements -- Bioactive Hybrid Materials for Photonic Microsystems It allows samples to be analyzed on site within a few minutes by integrating biotechnology, information technology, electronics, physics, and chemistry to realize small and cost-effective bio-photonic microsystems....

The Subregional Bone Assessment, a NASA study of the long-term effects of microgravity on the bones of International Space Station crewmembers, showed that the astronauts lost roughly 11% of their total hipbone mass over the course of their mission, more than an elderly woman in a year. While bone mass was regained after a year on Earth,...

Purdue University researchers have created a handheld sensing system its creators liken to Star Trek's "tricorder" used to analyze the chemical components of alien worlds. The new portable system is an ultrafast chemical analysis tool that could be used for detecting everything from cancer in the liver to explosives residue...

Methods are available for the determination of building stability in the event of an earthquake. These methods involve the development of existing shaking table technology to allow more efficient characterization of structural properties. View this technology here. An approach accompanied by a comprehensive algorithm and...

A researcher at Technische Universiteit Eindhoven (Eindhoven, the Netherlands) has developed a software patch that can increase a car's fuel efficiency to a total fuel savings of 2.6%, without having to replace any of the parts of the car. Uploading a software patch to the car's computer and adding one small cable suffices.

IM Mobile -- World's fastest, full-functionality, single-user Data Base Management System (DBMS), with unique built-in synchronization. It is about four times faster than Microsoft SQL Server 2005 Mobile on a PDA, making the user experience completely different. Click here.

Using optical fibers, researchers at the Georgia Institute of Technology have found a way to create a sensor that detects the direction from which a sound is coming under water. The new sensor could allow the U.S. Navy to develop compact arrays to detect quiet underwater targets, while also providing unambiguous directional...

A new technique for laser-cooling atoms in a cesium atomic fountain frequency standard relies on recirculation of laser light through the atom-collection region of the fountain. The recirculation, accomplished by means of reflections from multiple fixed beam-splitter cubes, is such that each of two...

A relatively simple technique for characterizing an all-resonant intracavity continuous- wave (CW) solid-state Raman laser involves the use of ring-down spectroscopy. As used here, “characterizing” signifies determining such parameters as threshold pump power, Raman gain, conversion...
