Four species of non-spore-forming bacteria collected from clean-room surfaces in spacecraft-assembly facilities could survive doses of ultraviolet (UV) radiation that would suffice to kill most known cultivable bacterial species. In a previous study, high UV resistance was...

Tiny telescopes have long been mounted on glasses to help visually impaired people perform tasks, such as driving. But many potential users have resisted using them due to their appearance, whereby the lens is mounted atop the regular lens or above the frame. Moreover, the magnified view through the telescope is narrow. Now,...

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...

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...

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...

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...

Brain-machine interfaces could someday be used routinely to help paralyzed patients and amputees control prosthetic limbs with just their thoughts. Now, University of Florida researchers have devised a way for computerized devices not only to translate brain signals into movement, but also to evolve with the brain as it...

An apparatus denoted a swab device has been developed as a convenient means of acquiring samples of contaminants from surfaces and suspending the samples in liquids. (Thereafter, the liquids can be dispensed, in controlled volumes, into scientific instruments for analysis of the contaminants.) The swab...

While cataloging cultivatable microbes from the airborne biological diversity of the atmosphere of the Regenerative Enclosed life-support Module Simulator (REMS) system at Marshall Space Flight Center, two strains that belong to one novel bacterial species were isolated. Based on 16S rRNA gene sequencing...

Special-purpose hand-held radio- transceiver units have been proposed as means of short-range radio powering and interrogation of surgically implanted microelectromechanical sensors and actuators. These units are based partly on the same principles as those of the units described in “Printed...

The use of a form of remote sensing to aid in the management of large turfgrass fields (e.g. golf courses) has been proposed. A turfgrass field of interest would be surveyed in sunlight by use of an airborne hyperspectral imaging system, then the raw observational data would be preprocessed...

A team led by Jun Ye, a physicist at JILA - a joint institute of the National Institute of Standards and Technology and the University of Colorado at Boulder - demonstrated an optical technique for simultaneously identifying tiny amounts of a broad range of molecules in the breath, potentially enabling a fast, low-cost...

An improved apparatus has been invented for use in determining the osmotic second virial coefficient of macromolecules in solution. In a typical intended application, the macromolecules would be, more specifically, protein molecules, and the protein solution would be pumped through a...

Researchers at Rensselaer Polytechnic Institute have developed a method to detect and destroy proteins, including dangerous ones such as anthrax, using light. The process exposes the proteins to invisible, near-infrared light, rendering them harmless. The technique lends itself to creating new antibacterial and...
