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.

Robots called electronics driver of 21st century

June 26, 2002

The robot could emerge as the driving force of electronics this century, according to Murata Manufacturing Co. Ltd. at the the Robotrex 2002 exhibition in Fukuoka, Japan.

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

SCIENTISTS ARE A WHISKER AWAY FROM SEMICONDUCTING NANOWIRES

June 25, 2002

Boron crystalline nanowires (“nanowhiskers”) may replace carbon nanotubes as nanoscale semiconductors.

3D maps show brain gene activity

June 25, 2002

A 3D map of the brain’s genetic activity should help researchers pinpoint the neurological underpinnings of autism, schizophrenia and other brain disorders.

AI to Assist Alzheimer’s Patients

June 25, 2002

The Activity Compass, a Palm handheld with a GPS receiver and wireless modem, will memorize an Alzheimer’s patient’s daily routine and offer him directions when he becomes lost or confused.

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.

Nanotech: Big Dreams, Small Steps

June 24, 2002

Diagnostic tools and sensors for bioscience and materials to enhance the fabrication of complex materials (such as gene chips) are the most likely nantechnology products to emerge in the next five years, according to experts.These will followed by diagnostic technologies to help researchers better understand and measure nanoscale interactions, mainly in biotech, then nanotherapeutic devices that will carry stores of drugs through the blood stream, and further off, nanoscale electronics.

Nanotech Tubes Could Form Basis of New Drug Purification Techniques

June 21, 2002

Researchers have developed a smart membrane containing tiny silica nanotubes that is capable of separating beneficial from useless or even harmful forms of a cancer-fighting drug molecule.

Theory Challenges Darwin Doctrine Of Common Descent

June 21, 2002

Cellular evolution began in a communal environment in which the loosely organized cells took shape through extensive horizontal gene transfer, according to Carl Woese, a microbiologist at the University of Illinois at Urbana-Champaign.

His theory challenges the longstanding Darwinian assumption known as the Doctrine of Common Descent — that all life on Earth has descended from one original primordial form.
On the evolution of cells, Carl R.… read more

Robot on the run

June 21, 2002

Scientists running an experiment with “living robots” that think for themselves said they were amazed to find one had escaped from a building and traveled out the parking lot.

“But there’s no need to worry, as although they can escape they are perfectly harmless and won’t be taking over just yet” mused Professor Noel Sharkey of the Magna science centre in Rotherham, South Yorkshire in Australia.
