An ultrasensitive medical imaging technique from Purdue University, which uses a pulsed laser and tiny metallic "nanocages," might enable early detection and treatment of disease. The system works by shining near-infrared laser pulses through the skin to detect hollow nanocages and solid nanoparticles - made of an...

It's illegal for health products with medical formulations to be accepted by the U.S. Food and Drug Administration without tests on animals - a situation that has serious ethical and moral implications. New research in the field of tissue engineering, by Professor Amit Gefen of Tel Aviv University's Faculty of...

Researchers from Northwestern University, the University of Illinois at Urbana-Champaign, and the University of Pennsylvania are the first to demonstrate a flexible silicon electronics device used for a medical application. The device produced high-density maps of a beating heart's electrical activity, providing a potential...

Current methods of device control include joysticks, which involve using one or both hands, external microphones that are cumbersome and pick up ambient noise, and external arrays that are also cumbersome and can restrict a user’s movement. Additionally, the external microphone and array...

Strategies were explored for inactivating resistance-bearing microorganisms, focusing on a new species (Bacillus horneckii sp. nov.) discovered on the surfaces of the Kennedy Space Center cleanroom facility in which the Phoenix lander was assembled. Two strains that belong to this novel species were...

A three-dimensional (3D) culture system for growing long-lived B lymphocytes has been invented. The capabilities afforded by the system can be expected to expand the range of options for immunological research and related activities, including testing of immunogenicity of vaccine...

The NASA liquid cooling/ventilating garment (LCVG) currently in use was developed over 40 years ago. With the commencement of a greater number of extra-vehicular activity (EVA) procedures with the construction of the International Space Station, problems of astronaut comfort, as well as the reduction of the...

To better exploit the principles of gas transport and mass transport during the processes of cell seeding of 3D scaffolds and in vitro culture of 3D tissue engineered constructs, the oscillatory cell culture bioreactor provides a flow of cell suspensions and culture media directly through a porous 3D scaffold...

Joining severed vessels is a recurring problem in trauma and surgery. The basic technology of joining vessels using sutures has been available for centuries, but remains a slow and tedious process. A complete system for micro-anastomosis of vessels was developed that involves a laser in...
