Microwaves Target Deep Tumors

Physicists at the University of Texas at Arlington have shown that using microwaves to activate photosensitive nanoparticles produces tissue-heating effects that ultimately lead to cell death within solid tumors. The new concept, which combines microwaves with photodynamic therapy, opens new avenues for targeting deeper tumors and has proven effective in rapidly and safely reducing tumor size.

Method and Apparatus for Performance Optimization Through Physical Perturbation of Task Elements

This technology can be used in sports psychology, marksmanship training, video gaming, and special forces training.NASA’s Langley Research Center has developed ZONE, an innovative method for improving athletes’ responses to stress, anxiety, and loss of concentration during competition. In the training environment, when the user successfully attains an optimal target state of psychophysiological functioning, the technology informs and/or rewards that user through real-time physical changes in the athletic equipment. For example, in the training setting, a golfer can work toward optimal concentration in the act of putting, leading to improved performance in real situations.

Portable Medical Diagnosis Instrument

Four cutting-edge sensor technologies enable minimally or non-invasive analysis of various biological samples.NASA has developed a novel technology strategy called “The NASA Analyzer” that would provide comprehensive in-flight medical diagnostic capability in a compact, handheld device for human deep-space missions such as Mars. Key features of the technology include the ability to handle multiple sample types (breath, saliva, blood), and the ability to measure virtually any analyte, including future analytes as they emerge. The device provides both non-invasive and minimally invasive sampling capabilities, which will be required during long-duration exploration missions. Breath and saliva are fully non-invasive and can provide critical health assessment information very rapidly. From small blood samples, information about macromolecular analytes, as well as blood cell counts, can be obtained. The device consists of four cutting-edge technologies integrated into a single, compact medical diagnostic tool with wireless (e.g., smartphone) capability. In addition to space applications, this innovative technology will very likely have important spinoffs in medicine and public health on Earth.
