A method and bioreactor for the continuous production of synchronous (same age) population of mammalian cells have been invented. The invention involves the attachment and growth of cells on an adhesive-coated porous membrane immersed in a perfused liquid culture medium in a microgravity analog...

A report describes a rover-type robotic wheeled vehicle recently built for use as a testbed for development of software for future rover-type vehicles. This vehicle is a derivative of the Field Integrated Design and Operations (FIDO) rover, which is a prototype Mars- exploration rover that also serves as a terrestrial...

A document discusses a technique for enabling the reception of spacecraft commands at received signal levels as much as three orders of magnitude below those of current deep space systems. Tone-based commanding deals with the reception of commands that are sent in the form of precise...

This technology provides an efficient and cost-effective way to measure absolute position in one or two dimensions using a new Point Coupled Linear Transformer (PCLT). The PCLT detects movement and position on flat or curved surfaces. The nature of its design provides the sensor with...

Philips is offering an innovative technology to dispel humans (and animals) from an area where they are unwanted. The new and patented dispelling light source (DLS) concept is based on disturbance of humans and/or animals using photosensitive stimuli. When switching a DLS system to the specifically programmed flickering...

A company is seeking unique technologies for automated hand, chuck, and grip product assembly applications (not CNC machining). Multiple sizes of gripping device are acceptable for different sized parts. The chuck or hand technology should be general purpose in nature, and show...

Technologies are sought that will provide a natural method for extending shelf life, the prevention of food deterioration (oxidation and/or spoilage), and growth of pathogenic micro-organisms along the full chain of fresh or processed food. The solution could be effective at any stage, from feedstock to...

Computer programs that are used to define safety margins for fiery spacecraft re-entries and help detect planets outside our solar system are co-winners of NASA's 2007 Software of the Year Award. Software engineers at NASA's Ames Research Center developed the Data-Parallel Line Relaxation, or DPLR, which is used to...

Ohio State University physicists have invented a new kind of MRI technique to see inside a magnet that's smaller than the head of a pin. The magnet is a ferromagnet and has too strong of a magnetic field to be studied with typical MRI. The technique may eventually enable the development of extremely small computers, and give doctors...

NASA's Innovative Partnerships Program has selected seven Small Business Innovation Research, or SBIR, companies to participate in reduced-gravity test flights in early September. The companies will have the opportunity to test their newly developed hardware on an aircraft that simulates the weightless conditions of...

Purdue University researchers have uncovered a potentially less expensive method to produce solid-state lighting based on light-emitting-diode (LED) technology. This development could hasten the day when LEDs, which are more energy efficient and longer lasting than conventional incandescent light bulbs, become the preferred...

Researchers from UCLA and the Veterans Affairs Greater Los Angeles Healthcare System have developed a design for an automated, wearable artificial kidney, or AWAK. Around 1980, a similar artificial kidney machine was built which was portable, but not wearable. The new technology would allow patients to go about their regular...

NASA's program of technology prizes consists of seven competitions held throughout the year. The program began in 2005 and is known as Centennial Challenges, in recognition of the centennial of powered flight. The prizes are offered to independent competitors who work without government support, including small businesses,...

Researchers at Auburn University's Samuel Ginn College of Engineering have produced antimicrobial coatings with potential to prevent diseases from spreading on contaminated surfaces - possibly solving a growing problem not only in hospitals but also in schools, offices, airplanes and elsewhere. The Auburn researchers mixed...

Researchers at the University of Saskatchewan have opened an engineering lab to design a ventilation system that could protect schools, hospitals, and other public buildings from chemical warfare and bioterrorist attacks. The lab's research will help determine how the Early Warning and Response system (eWAR) can both filter...

Compressed air stored in underground caverns could answer the need for lower cost electrical energy, according to Sandia National Laboratory scientists. The scientists are examining the feasibility of using an aquifer site near Des Moines, IA, to power a plant able to generate up to 13,400 megawatts per hour with 50...

Scientists at the ETH Zurich Departments of Mechanical and Process Engineering and Computer Science have teamed with supercomputingexperts at IBM's Zurich Research Laboratory to develop an accurate, powerful and fast method to automate the analysis of bone strength. The method combines density measurements with...

Swimmers around the world are breaking records this year like never before, including at this week's U.S. Olympic trials. Some attribute it to extensive training as athletes prepare to compete at this summer's games in Beijing, China. Others, however, say one factor may be a new space-age swimsuit made of fabric tested at...

An international team of researchers has created the first complete high- resolution map of how millions of neural fibers in the human cerebral cortex - the outer layer of the brain responsible for higher level thinking - connect and communicate. Their groundbreaking work identified a single network core, or hub, that may be key to...

Scientists at the University of Texas at Austin have developed a laser "microscalpel" that destroys a single cell while leaving nearby cells intact, which could improve the precision of surgeries for cancer, epilepsy and other diseases. The device uses femtosecond lasers, which produce extremely brief, high-energy light pulses...
