VR hallucinations used to treat schizophrenia

July 2, 2002

A virtual reality environment has been designed by a team at the University of Queensland in Brisbane to help treat people with schizophrenia, using a simulated living room projected onto a wrap-around screen and a soundtrack with an abusive running commentary.
For example, it can mimic common hallucinations: walls appear to be closing in, photographs of faces morph, straight lines such as the edge of pictures wobble. The idea is… read more

Nanoparticles Cut Tumors’ Supply Lines

July 1, 2002

Cancer researchers packed a tiny particle with a gene that forces blood vessel cells to self-destruct, then “mailed” the particle to blood vessels feeding tumors in mice. A single treatment erased large tumors in mice in about 6 days.

New treatment for depression

June 28, 2002

Psychiatrists are using transcranial magnetic stimulation (TMS) to treat depression that doesn’t respond to drugs.

The experimental treatment applies a pulsed magnetic field to the frontal cortex, which links to the limbic system, a regulator of emotion.

Healthy Shocks to the Head

June 28, 2002

Brain pacemakers, or “deep-brain stimulators,” are starting to show promise for treating neurological disorders, such as Parkinson’s, epilepsy, dystonia, and severe obsessive-compulsive disorder.

Nano device could result in 1000:1 increase in storage density

June 27, 2002

University at Buffalo materials researchers have developed an extremely sensitive nanoscale device that could shrink ultra-high-density storage devices factor of a 1,000.

The magnetic sensor, made of nickel and measuring only a few atoms in diameter, could ultimately increase data storage capacity to a terabit per square inch.

A New Twist on Light Speed

June 27, 2002

Glasgow scientists have measured a single photon’s orbital angular momentum for the first time. The research could lead to speeding up optical communications by allowing each photon sent over fiber optic lines to encode multiple bits as quantum orbital states.

Magnetic Future

June 26, 2002

Researchers at GE and IBM are developing “patterned media”-based disks that hold between 30 and 40 gigabits per square centimeter, ten times the density of today’s products, and the storage density might be pushed to more than 150 gigabits per square centimeter.

The technology involves physically isolating a disk’s magnetic grains from one another on nanoscale “islands.” Currently, several hundred magnetic grains are needed to store a bit clearly,… read more

Science-Technology Drive Is Urged to Fight Terror

June 25, 2002

The National Research Council has developed a blueprint for using current technologies and creating new capabilities to reduce the likelihood of terrorist attacks. The recommendations include protecting and controlling nuclear weapons and material, producing sufficient supplies of vaccines and antibodies, securing shipping containers that could hide bombs or toxins, protecting power grids more effectively, improving ventilation systems in public buildings, emergency communications for workers responding to disasters, and more research… read more

At Los Alamos, Two Visions of Supercomputing

June 25, 2002

Heat may be a limiting factor to Moore’s law. By 2010, scientists predict, a single chip may hold more than a billion transistors, giving off 1,000 watts of thermal energy — far more heat per square inch than a nuclear reactor.

Already, Los Alamos National Laboratory’s 30-teraops Q computer, designed to provide full-scale, three-dimensional simulation of the physics involved in a nuclear explosion, will require 5 megawatts of energy.… read more

The New Hearing Aid

June 25, 2002

Adding increased stochatic (random) noise to cochlear implant signals makes the neural pattern more natural, increases the perceived dynamic range, allowing patients to detect subtler sounds, according to Dr. Jay Rubinstein, associate professor of otology at the University of Iowa, speaking at the conference of the American Society for Artificial Internal Organs.

Human Demand Exceeds Earth’s Sustainable Supply

June 24, 2002

The global population exhausts a supply of natural resources equivalent to that produced by 1.2 earths each year, eroding nature’s ability to regenerate. This era of unbounded exploitation may soon be forced to a screeching halt, according to a study published today in the Proceedings of the National Academy of Science.
