Printing Cheap Chips

November 26, 2007

Kovio’s new technology for printing inorganic transistors could lead to large-area displays and ultracheap smart cards.

Trapped cells make micromotors

April 20, 2005

Researchers from the Tata Institute of Fundamental Research in India have showed that it is possible to make live Chlamydomonas reinhardtii cells rotate while pinned in a laser trap.

The energy of a light beam can be used to manipulate and trap cells much like the way wind moves objects at a larger scale.

The ultimate goal is to design controllable motored nanomachines.

Stanford researchers develop full-duplex wireless radios

February 18, 2011

Stanford researchers have developed the full-duplex first wireless radios, meaning that can send and receive signals simultaneously on a single channel. Their research could help build faster, more efficient communication networks, at least doubling the speed of existing networks.

“Textbooks say you can’t do it,” said Philip Levis, assistant professor of computer science and of electrical engineering. “The new system completely reworks our assumptions about how wireless networks can… read more

Glowing nanobots map microscopic surfaces

March 1, 2002

Molecular robots used to explore a surface’s terrain can produce maps of microscopic structures and devices with higher resolutions than those produced by conventional microscopes, research shows.
University of Washington researchers modified microtubules by fixing kinesin molecules (which normally move materials around cells along microtubule pathways) on a surface, causing the microtubules to propel themselves randomly on the surface.

By attaching a fluorescent dye to the microtubules, the… read more

‘Motorized’ DNA opens door to autonomous molecular experiments

April 17, 2009

Miniaturized intelligent systems using RNA polymerase as a molecular motor to move and direct molecules of DNA may allow for running billions of automated biology experiments at once, University of Wisconsin-Madison have found.

The motorized molecules steer themselves by sensing “fuel,” a chemical nutrient that draws the molecule in, by temperature, or through nanoscale geometric patterns on the surface of a culture plate.

The technology could aid the… read more

Duke Scientists Map ‘Silenced Genes’

December 3, 2007

Duke University scientists now have identified switched-off “silenced genes,” creating the first map of this unique group of about 200 genes believed to play a profound role in people’s health.

The work marks an important step in studying how our environment — food, stress, pollution — interacts with genes to help determine why some people get sick and others do not.

Bandwidth Advance Hints at Future Beyond Wi-Fi

May 4, 2005

With 500 megabits/sec and higher capacity, ultrawideband (UWB) will eventually replace the ubiquitous Wi-Fi wireless standard.

The future could include wireless home networks that simultaneously interconnect multiple screens, computers and audio and video streams.

Researchers demo secure storage of quantum data

April 4, 2002

Harvard University researchers have succeeded in bringing practical quantum computers one step closer to reality by storing qubits (quantum bits) in a memory and retrieving them later, without having to observe, and therefore invalidate, their values. The first step, demonstrated last year, was the ability to store a laser-encoded signal in the spin states of atoms and then nondestructively read them back out.

The next step: demonstrate that quantum… read more

Computer Program to Take On ‘Jeopardy!’

April 27, 2009

IBM plans to announce Monday that it is in the final stages of completing a computer program named Watson to compete against human “Jeopardy!” contestants, using a Blue Gene supercomputer and a database with a significant fraction of the Web now indexed by Google.

If the program — a new class of software that can “understand” human questions and respond to them correctly — beats the humans, the field… read more

Argosy Visible Body Out in Beta

December 10, 2007
(Argosy Publishing)

Argosy Publishing has released its impressive 3D anatomic visualization system to the public through their Internet Explorer-only site (free with registration).

It is a powerful tool to look at the body at every depth and from every angle, browse through the various anatomical systems, and easily locate obfuscated and hard to see details.

Air Force Seeks Bush’s Approval for Space Weapons Programs

May 18, 2005

A new Air Force strategy, Global Strike, calls for a military space plane carrying precision-guided weapons armed with a half-ton of munitions.

The “common aero vehicle” could strike from halfway around the world in 45 minutes.

The “Rods From God” space program aims to hurl cylinders of tungsten, titanium or uranium from the edge of space to destroy targets on the ground.

A third program would bounce… read more

Android, take a letter: Robotic hand helps people type

March 4, 2011

Virginia Tech researchers have designed a robotic hand that they hope to optimize for keyboard work, using 19 tiny servo motors to actuate their hand, all placed in a forearm and connected to the joints via wire tendons that ensure proper joint angles while typing.

In tests, one hand managed a top speed of 20 words per minute, but by adding a left hand, a typing speed of over… read more

Internet Insight: Moore’s Law & Order

April 24, 2002

Kurzweil’s Law of Accelerating Returns forsees faster growth in computational power over the next several decades than Moore’s Law predicts. Kurzweil said we can “expect the process to accelerate at a double exponential rate.”"The next paradigm, the sixth, will be three-dimensional molecular computing,” Kurzweil said. “In the past year, there have been major strides, for example, in creating three-dimensional carbon nanotube-based electronic circuits.”

Lucent Technologies and IBM have already… read more

Would you pay $68,000 to unlock the secrets of your genetic code?

May 1, 2009

Bidding kicked off last week at $68,000 on a 10-day eBay auction whose prize includes personal genome sequencing, analysis, and interpretation services provided by Cambridge, Mass.-based genetics firm Knome, Inc.

The auction’s winner also participates in a roundtable discussion with Knome’s geneticists, clinicians and bioinformaticians to review the winner’s sequence data, and a private dinner with George Church, co-Founder and Knome’s chief scientific advisor.

The auction is intended… read more

“Popping” bubbles to treat cancer

December 17, 2007

University of Oxford scientists are trying to harness the energy released when bubbles collapse as a way of killing off cancer cells.

They have built a device to beam waves of ultrasound into the body, generating bubbles at the site of a tumor.

When these bubbles “pop,” they release energy as heat, killing rogue cells.

The new technique will be used in clinical trials to treat patients… read more
