Clever Wiring Harnesses Tiny Switches

July 17, 2001

Hewlett-Packard researchers are starting to tackle how to wire the tiny molecular switches together into useful devices.

Two years ago, scientists at Hewlett-Packard and U.C.L.A. announced that they had created a custom-designed, carbon-based molecule called rotaxane that could act as a switch. A ring-shape structure slides up or down along the rest of the molecule, changing its electrical resistance. The switch mechanism consisted of rotaxane molecules between two crossed… read more

Sony Pushes Better Cinema Through Digital

February 20, 2009

Sony expects to increase penetration of its 8.8 million pixel 4K SXRD Digital Cinema technology from the current 300 screens to 3,000 within the next two years.

Nanoscale computer memory retrieves data 1,000 times faster

September 18, 2007

Scientists from the University of Pennsylvania have developed nanowires capable of storing computer data for 100,000 years and retrieving that data a thousand times faster than existing portable memory devices such as Flash memory and micro-drives, all using less power and space than current memory technologies.

ET Visitors: Scientists See High Likelihood

Our world is immersed in a much larger extraterrestrial civilization, recent astrophysical discoveries suggest.

Self-assembling nanotubes

August 13, 2001

The principle that makes DNA strands link together may someday be used to manufacture molecular wires and other components for use in electronic devices, according to Hicham Fenniri, an assistant professor of chemistry at Purdue Univ. To develop the self-assembling structures, Fenniri and his colleagues borrowed chemistry from DNA to create a series of molecules that are “programmed” to link in groups of six to form rosette-shaped rings, which then… read more

Nanotechnology and Technology Acceleration Buzz is Higher Because Actual Developments Are Showing Pessimists Were Wrong

February 26, 2009

The current nano buzz includes four innovations:

1. New research in using conductive nanomaterials for neuroengineering applications proposes carbon nanotubes as ideal probes for bidirectional interfaces in neuroprosthetics and as nanotools to endogenously (re)engineer single-neuron excitability and network connectivity.

2 Recent advance in seeded growth as the ultimate approach to producing metal nanocrystals with precisely controlled sizes, shapes, and compositions the necessary first step toward their use and… read more

Robot dogs race to be soldier’s best friend

September 26, 2007

DARPA has selected six university research teams to compete to develop the best algorithms for controlling a robot puppy called LittleDog.

The goal is to identify the best adaptive strategy for moving over irregular surfaces.

The robot has three motored joints on each leg, and its movements are controlled precisely by an on-board computer. An internal gyroscope lets the robot sense its orientation, while an external motion-capture system… read more

Novel technology detects human DNA mutations

January 26, 2005

Nanosphere says its new ClearRead nanoparticle-based technology allows detection of a SNP (Single Nucleotide Polymorphism, which indicates the extent to which the gene is normal or mutated) in an unknown genotype with a greater than 99 percent confidence threshold and can be used with human DNA obtained from samples as small as a drop of blood.

The technology, reported in the February 2005 (Volume 33, Number 2), issue of… read more

What is Traitorware?

December 28, 2010

Your digital camera may embed metadata into photographs with the camera’s serial number or your location. Your printer may be incorporating¬†a secret code on every page it prints which could be used to identify the printer and potentially the person who used it. If Apple puts a particularly creepy¬†patent it has recently applied for into use, you can look forward to a day when… read more

Spectrum Wars

September 6, 2001

The promise of ubiquitous wireless Internet access is on hold as TV broadcasters, the military, telecom companies and others secretly squabble over scarce spectrum space. Congress wants to auction off some of the prime spectrum used by the Pentagon. The Pentagon wants to take broadcasters’ HDTV spectrum, while broadcasters want to auction it off and use the money for developing digital television.

The public knows little about this; even… read more

Scientists Create Light-Bending Nanoparticles

March 4, 2009

Rice University researchers discovered that Cup-shaped gold nanostructures can bend light in a controllable way, acting like three-dimensional nano-antennas, Rice University researchers have discovered.

This property should prove useful in developing new optical materials and devices, such as solar cells, light attenuators, and chip-to-chip optical interconnects.

Freedom Phones and PINs: How to Find Osama bin Laden and Other Terrorists

October 1, 2001

Scientists and Middle East experts have come up with an idea for inexpensive “informer cell phones” dropped from airplanes and an anonymous reward scheme to encourage those with information on the identity and whereabouts of terrorists to provide this information to U.S authorities such as the FBI. The intelligence gathering operation, proposed by physicist and radio personality Dr. Bill Wattenberg on KGO radio in San Francisco, uses a unique PIN… read more

Unveiling the “Sixth Sense,” game-changing wearable tech

March 11, 2009

TED has just released the video of MIT scientists Pattie Maes & Pranav Mistry unveiling their “Sixth Sense,” a wearable device with a projector, as in Minority Report — the buzz of TED.

Invisibility Made Easier

October 15, 2007
Anthony Hoffman, Princeton University

Princeton University researchers have demonstrated a new way to create metamaterials that bend light in unusual ways.

The new proces allows for metamaterials that are both higher performing and much easier to manufacture, perhaps bringing these applications closer to reality.
