Brain Scan
Researchers at University of Toronto and Bloorview, Canada's largest children's rehabilitation hospital, have developed a technique that uses infrared light brain imaging to decode preference. When children with disabilities can't speak or gesture to control their environment, they may develop a learned helplessness that impedes...

Diagnosing Brain Aging
UCLA scientists have used brain-scan technology, along with patient-specific information on Alzheimer's disease risks, to help diagnose brain aging before symptoms appear. The researchers used positron emission tomography (PET), which allows the revealing of plaques and tangles, the hallmarks of neurodegeneration. The PET...

Portable Ultrasound Device
Cornell University graduate student George Lewis is trying to shrink ultrasound devices to make them practical for any hospital or medical research lab. Lewis has developed a palm-sized, battery-powered ultrasound device powerful enough to stabilize a gunshot wound or deliver drugs to brain cancer patients. Current...

Brain Games
A team of scientists studying the human brain at Washington University School of Medicine in St. Louis and the University of Chieti, Italy, report that a simple decision-making task does not involve the frontal lobes, where many of the higher aspects of human cognition, including self-awareness, are thought to originate. Instead, they...

Protein Detector
Scientists from Novartis Institute for Biomedical Research and the British Columbia Cancer Agency have demonstrated a new instrument that makes it possible to detect and quantify multiple different clinically important proteins in a single tumor sample using conventional staining. Currently, pathologists usually need a separate...

Breast Cancer Detection
Scientists from Finland, Germany, and the European Synchrotron Radiation Facility (ESRF) have developed a new X-ray technique for the early detection of breast cancer. Current X-ray mammography fails to identify about 10 to 20% of palpable breast cancers because glandular tissues can mask cancer lesions. Better results are...

UV-Resistant Non-Spore-Forming Bacteria From Spacecraft-Assembly Facilities
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...

Purifying Nucleic Acids From Samples of Extremely Low Biomass
A new method is able to circumvent the bias to which one commercial DNA extraction method falls prey with regard to the lysing of certain types of microbial cells, resulting in a truncated spectrum of microbial diversity. By prefacing the protocol with glass-bead-beating agitation...

Embedded Telescope
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,...

Mini Magnet MRI
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...
