Carnegie Mellon University Researchers Develop Magnetic Levitation-Based Haptic Interface For Computers
Carnegie Mellon researchers have developed a new type of haptic interface employing magnetic levitation enabling computer users to physically interact with simulated objects and environments on their computer screens. (1999-02-08)

Mild Behavior Problems In Preterm Infants Not Cause For Alarm
Babies born two to three months prematurely may have mild behavior and sensory response problems. Most develop normal motor and mental function. Preterm seem more active and more sensitive to touch than babies carried full-term--perhaps due to less time in the womb or an immature central nervous system.. (1998-11-30)

Brain Study Sheds Light On The 'Phantom Limbs' Of Amputees
For some amputees, the pain and disability of losing an arm or leg are followed by a lifetime of other disturbing effects. In this week's Science, researchers paint a new picture of the changes that occur deep in the brain after amputation. (1998-11-05)

Summer Science: The Chemistry Of Ice Cream Revealed
There's more to making ice cream than simply mixing and freezing some cream, sugar and delicious flavorings, according to Michael Brewster, engineering, safety and environmental director for Perry's Ice Cream in Akron, New York. (1998-08-25)

October Workshop To Write Next Chapter In Publishing
This news item, which appeared in the July 20, 1998, NIST Update newsletter, alerts readers to the first-ever workshop on hand-held electronic books to be held in October 1998 at NIST's Gaithersburg, Maryland, headquarters. Book publishers and others involved in electronic book publishing will showcase the latest information technology advances -- such as improved flat-panel displays and increased storage capacity - - making E-books the next evolutionary step in field.

Pitt, Carnegie Mellon Researchers Shed Light On 'The Nature Of The Self'
Researchers at the University of Pittsburgh and Carnegie Mellon University have taken an important step toward determining how the body comes to be identified as part of the self. According to the researchers, the concept of body self-identification arises out of the way humans perceive their bodies. (1998-02-19)

Researchers Identify New Mechanism Underlying Pain
New research on neuropathic pain -- the kind of burning, shooting pain for which standard analgesics provide little relief -- is producing evidence that the immune system is intimately involved in the initiation and maintenance of pain, through production of proteins called cytokines. (1998-02-13)

Neurosurgical Technique Relieves Excessive Sweating
Some people -- about 1 percent of the population -- sweat copiously following mild stimulation or none at all. They suffer from hyperhidrosis, an embarrassing and often debilitating condition that seems to be more common in people of Asian descent. A simple surgical procedure performed by neurosurgeons at Northwestern University Medical School can relieve this condition. (1998-01-26)

New Simulator Technology To Give Surgeons 'Feel' Of Really Operating
Surgical students soon will be able hone their skills with simulators that for the first time present a realistic feel of performing surgery thanks to a research project under way at the University of Washington. The project also could improve patient care by leading to the development of instruments that enhance surgeons' sense of touch. (1997-11-19)

Evidence For A Radio-Like Mechanism In The Brain Found At The Weizmann Institute
Weizmann Institute scientists have found evidence that when the brain interprets input obtained through touch, it uses a mechanism remarkably similar to that of an FM radio. This research, reported in the 10/14 issue of PNAS, provides a possible new explanation for the way the brain processes sensory information. (1997-10-13)

UF Study Reveals Loss In Sensory Perception May Not Be Linked To Aging
Aging has little effect on smell, taste or touch, according to a six-year study involving volunteers smelling lemons and some 40 other scents including natural gas and bubble gum, said Dr. Marc Heft, director of the Claude Pepper Center for Research on Oral Health in Aging at UF's College of Dentistry.
