FAQ: Forty years of Moore’s Law

April 1, 2005

Moore’s law will likely begin to slow down to a three-year cycle in the next decade and require companies to adopt alternative technologies.

Some say the ability to shrink transistors will start to become problematic by around 2010. Others, such as Intel’s director of technology strategy, Paolo Gargini, paint a more gradual picture. Around 2015, they say, manufacturers will start to move toward hybrid chips, which combine elements of… read more

Microchip gives blind chance of sight

January 28, 2002

A computer chip implanted near the eye’s retina is may offer some restored vision to people blinded by eye diseases such as retinitis pigmentosa and age-related degeneration of the eye.
To capture images, an external camera mounted in an eyeglass frame captures the image and converts it into an electrical signal that is then electronically transmitted to a flexible silicon biochip surgically attached near the retina. The chip electronically stimulates… read more

Finding a fair price for free knowledge

June 26, 2009

If we really want to end scarcity, we will have to build institutions that promote knowledge-sharing, while at the same time ensuring that there are incentives for creative and technical minds to contribute.

Wikipedia and Google’s book-scanning projects are examples of such institutions.

Did dreams of computer utopia cause economic collapse?

May 26, 2011

In Love and Power, aired May 23 in the UK on BBC, British documentarian Adam Curtis links the Objectivist philosophy from the 1950s — which promoted rationality and an individual’s pursuit of happiness — with a belief in the infallibility of computers, which he argues brought about the economic booms of the 1990s as well as the recent catastrophic economic collapse.

Electromagnetic Railgun Blasts Off

February 7, 2008

The Naval Surface Warfare Center has fired the most powerful electromagnetic railgun, sending a seven-pound bullet out at seven times the speed of sound with 10.6 megajoules of kinetic energy.

The device is part of the U.S. navy’s railgun development program. A railgun could eventually send a 40-pound slug 200 miles in six minutes–10 times the range of the navy’s current primary surface support gun, the MK45.

Laser beams sort stem cells by springiness

April 13, 2005

Measuring the elasticity of cells using a new laser technique promises to pinpoint human stem cells in blood and distinguish cancerous cells from benign ones, say researchers.

Inventor of artificial hand sees ‘bionic’ replacement parts becoming more human

February 14, 2002

Bionic limb replacements that look and work exactly like the real thing could be realized within a decade, thanks to fast advances in human-to-machine communication and miniaturization.

Writing in Science, Feb. 8, Rutgers biomedical engineer and inventor William Craelius, whose Dextra artificial hand is the first to let a person use existing nerve pathways to control individual computer-driven mechanical fingers, says “bionic technologies can be adapted for restoring some… read more

Ray Kurzweil on How to Combat Aging

July 7, 2009

Health, medicine, and biology is now an information technology, in sharp contrast to the linear growth of hit or miss approaches that have characterized medicine up until recently, and these exponential technologies will be a million times more powerful in 20 years, allowing us to intervene in the aging process, says Ray Kurzweil.

New technology could inspire brain implant for detecting, treating seizures

June 2, 2011

Researchers at the University of Pittsburgh have developed a novel technology to precisely modulate individual neurons in rats, allowing the molecular, neuronal, and circuit functions to be analyzed with unprecedented precision.

The researchers demonstrated a novel way of loading specific drugs onto an array of electrodes and triggering their release into cultured rat neurons, allowing for more precise insight into the cellular mechanisms of neuronal… read more

Finding May Solve Riddle of Fatigue in Muscles

February 12, 2008

Columbia University researchers say they have determined why muscles get tired: their tiny channels start leaking calcium, and that weakens contractions. At the same time, the leaked calcium stimulates an enzyme that eats into muscle fibers, contributing to the muscle exhaustion.

They have devised an experimental drug that can eliminate fatigue. Drugs that stop calcium leaks may also help patients with congestive heart failure.

Trapping atoms for quantum computing

April 26, 2005

Ohio State University scientists have taken a step toward the development of quantum computers by making tiny holes in an egg carton-shaped surface of laser light that could one day cradle atoms.

They’ve been able to form about a billion gaseous rubidium atoms into a pea-sized cloud with magnetic fields. Now they are working to move that cloud into position above a chip supporting an optical lattice formed where… read more

Dr. Aibo, You’re Wanted in O.R

March 11, 2002

MacDonald Dettwiler and Associates (MDA) of Richmond, British Columbia is developing a robotic arm that will enable surgeons to perform more precise brain surgery.
The robot will perform a variety of procedures, including placing biopsy needles into the brain and dissecting blood vessel abnormalities during micro-surgery. It consists of two robotic arms and a two cameras, providing 3-D stereoscopic views for the surgeon.

The company is also working with… read more

Social networking site for researchers aims to make academic papers a thing of the past

July 16, 2009

myExperiment, the social networking site for scientists, has set out to challenge traditional ideas of academic publishing as it enters a new phase of funding.

Building Organs Even the Prudish Can Handle

February 15, 2008

Dr. Carla Pugh, a surgeon at the Northwestern University medical school, has developed low-cost simulators for training doctors to do “uncomfortable” examinations of breast, pelvic, and prostate areas.

Self-cloning robots are a chip off the old block

May 12, 2005

The first self-replicating, scalable robot, designed by Cornell University scientists, uses small mechanical building blocks that can attach themselves to one another using electromagnets, all equipped with an identical set of instructions.

It could herald a fundamental rethink of how robots are used in remote environments where repairing them is difficult.
