Resemblance between cataplexy during status cataplecticus, normal REM sleep
The first efforts to identify the neural structures and pathways underlying cataplexy during status cataplecticus in a narcoleptic patient, with the use of brain perfusion single photon emission computed tomography (SPECT), have led to the discovery that cataplexy during status cataplecticus, a case of prolonged cataplexy, partially resembles... view more...

PET accurately identifies esophageal cancer patients' positive responses to chemotherapy
Early metabolic imaging with positron emission tomography (PET) accurately identifies patients responding to chemotherapy for esophageal cancer, noted German researchers at the 54th Annual Meeting of SNM, the world's largest society for molecular imaging and nuclear medicine professionals. view more (2007-06-04)
Long-distance record -- 'Quantum keys' sent 200 kilometers
Particles of light serving as "quantum keys"-the latest in encryption technology-have been sent over a record-setting 200-kilometer fiber-optic link by researchers from the National Institute of Standards and Technology (NIST), NTT Corp. in Japan, and Stanford University. view more (2007-06-04)
Cassini findings suggest complex story of venting at the south pole of Enceladus
Evidence is mounting that the atmosphere of Enceladus, first detected by the Cassini Magnetometer instrument, is the result of venting from ground fractures close to the moon's south pole. view more (2005-08-31)
Brain network related to intelligence identified
A primary mystery puzzling neuroscientists - where in the brain lies intelligence? - just may have a unified answer. view more (2007-09-12)
Mayo Clinic researchers use ultrasound to describe subtle heart muscle motions
By using sound waves Mayo Clinic researchers have described subtle changes in the motion of the heart that are measurable by ultrasound and may improve understanding of heart function, and possibly be a noninvasive aid in predicting impending heart damage including heart attacks. view more (2005-08-01)
Brain imaging studies show attention to thinking in schizophrenia improves outlook for patients
A focus on schizophrenia as 'a disorder of thinking' promises much for patients with the condition, according to Dr Tonmoy Sharma, Head of the Section of Cognitive Psychopharmacology (SCP) at the Institute of Psychiatry. In a presentation to journalists during Brain Awareness Week, Dr Sharma outlined new research showing the importance of... view more... (1999-03-16)
Crystal bells stay silent as physicists look for dark matter
Scientists of the Cryogenic Dark Matter Search experiment today announced that they have regained the lead in the worldwide race to find the particles that make up dark matter. The CDMS experiment, conducted a half-mile underground in a mine in Soudan, Minn., again sets the world's best constraints on the properties of dark matter candidates. view more (2008-02-26)
Using nano-magnets to enhance medical imaging
Nanoscale magnets in the form of iron-containing molecules might be used to improve the contrast between healthy and diseased tissue in magnetic resonance imaging (MRI)—as long as the concentration of nanomagnets is carefully managed. view more (2007-02-02)
Making strides in quantum dot infrared photodetectors
Researchers at Northwestern University have made significant strides in the development of quantum dot infrared photodetectors -- technology that may provide new imaging techniques with applications in medical and biological imaging, environmental and chemical monitoring, night vision and infrared imaging from space. view more (2007-05-18)
Modified electron microscope identifies atoms
A new electron microscope recently installed in Cornell's Duffield Hall is enabling scientists for the first time to form images that uniquely identify individual atoms in a crystal and see how those atoms bond to one another. And in living color. view more (2008-02-22)
Novel Non-Invasive Imaging Technology May Allow Precise Diagnosis of Coronary Artery Disease, Treatment Tailoring
A study focusing on a new non-invasive imaging technology—one that may enable more precise diagnosis of coronary artery disease and treatment tailoring in individual patients—was released by Israeli researchers at SNM's 53rd Annual Meeting June 3—7 in San Diego. view more (2006-06-08)
Jefferson Scientists See Breast Cancer Gene Activity from Outside the Body
Researchers at Jefferson Medical College and Jefferson's Kimmel Cancer in Philadelphia have used PET imaging to see hyperactive cancer genes inside breast tumors in laboratory animals, marking the first time such gene activity has been observed from outside the body. view more (2007-11-29)
New technology developed at Barrow Neurological Institute enhances MRI capabilities
Researchers at Barrow Neurological Institute in Phoenix have developed a new method that allows technicians to obtain clearer Magnetic Resonance Imaging (MRI) scans with less sensitivity to patient motion. view more (2006-01-05)
Chang'e-1 - new mission to Moon lifts off
A bold new mission to the Moon was launched today by the Chinese National Space Administration (CNSA). Chang'e-1 blasted off from the Xichang Satellite Launch Centre, Sichuan, atop a Long March 3A rocket. view more (2007-10-25)
Bioluminescence at the service of a novel cerebral imaging technique
