X-ray lasers take spectroscopy to a new extreme

June 13, 2012


In experiments resembling an atomic-scale shooting gallery, researchers are pioneering a new method for chemical analysis by zapping the innermost electrons out of atoms with powerful X-ray laser pulses from SLAC’s Linac Coherent Light Source (LCLS).

The technique, developed by an international research team, allows chemical analysis with atomic resolution, taking spectroscopy to a new extreme.

“This is a powerful method to investigate complex molecules… read more

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

How Small Can Computers Get? Computing In A Molecule

December 30, 2008

Researchers at the French National Scientific Research Centre’s (CNRS) Centre for Material Elaboration & Structural Studies have designed a simple logic gate with 30 atoms that perform the same task as 14 transistors.

They are focusing on two architectures: one that mimics the classical design of a logic gate but in atomic form, including nodes, loops, meshes etc.; and another, more complex process that relies on changes to the… read more

Self-assembled nanostructures function better than bone as porosity increases

July 11, 2007

Nanoscale silica materials self-assembled in artificially determined patterns can improve upon nature’s designs, such as bone material, researchers have found.

The silica nanostructures may improve performance where increased pore volume is important. These include modern thin-film applications such as membrane barriers, molecular recognition sensors, and low-dielectric-constant insulators needed for future generation of microelectronic devices.

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

EPFL developing connectors for modular floating robots

June 19, 2012


The EPFL (École Polytechnique Fédérale de Lausanne) Laboratory of Intelligent Systems (LIS) is working on a robot made up of soft, floating modules that connect to each other through electroadhesion.

Electroadhesion uses very high voltages to generate a charge differential between two surfaces (even on non-conductive surfaces), causing them to stick together.

This makes it an ideal dynamic connector for soft, modular… 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

Ten extinct beasts that could walk the Earth again

January 8, 2009

The genomes of several extinct species besides the mammoth are already being sequenced, but turning these into living creatures will not be easy.

It’s only going to be possible with creatures for which we can retrieve a complete genome sequence. “It’s really only worth studying specimens that are less than 100,000 years old,” says Pennsylvania State University molecular biologist Stephan Schuster.

Project to create a molecule-sized processor

November 23, 2010

Singapore and European research organizations are working together to build what is essentially a single-molecule processor chip. As a comparison, a thousand of such molecular chips could fit into one of today’s microchips.

The ambitious project, termed Atomic Scale and Single Molecule Logic Gate Technologies (ATMOL), will establish a new process for making a complete molecular chip. This means that computing power can be increased significantly but take up only a… read more

Man to battle machine in poker matchup

July 23, 2007

Poker champion Phil Laak has a good chance of winning when he sits down this week to play 2,000 hands of Texas Hold’em — against a computer.

It may be the last chance he gets. Computers have gotten a lot better at poker in recent years; they’re good enough now to challenge top professionals like Laak, who won the World Poker Tour invitational in 2004.

But it’s only… read more

Without Apology, Leaping Ahead in Cloning

May 31, 2005

Dr. Woo Suk Hwang of South Korea hopes to use animal stem cells to treat spinal cord injuries in rats, dogs and, possibly, monkeys.

If the animal trials go well, he hopes to apply for permission in South Korea and the United States to start conducting human trials in two to three years.

Newt Gingrich Gets Small

May 21, 2002

Nanotechnology is “the investment with the largest payoff over the next 50 years,” said Newt Gingrich, former speaker of the House of Representatives, in a keynote at NanoBusiness Spring 2002.

Stanford announces $100 million energy institute

January 14, 2009

Stanford University has received $100 million to create a new energy institute where scholars can study everything from solar cells to energy markets and economics.

Streaming video could strain Internet’s capacity

December 3, 2010

A report by Internet network management firm Sandvine estimates that as much as 43 percent of peak Internet traffic is eaten up by real time entertainment, mostly streaming video. As that grows rapidly, it imperils the ability to pipe entertainment to neighborhoods.

Netflix traffic alone makes up more than 17 percent of the data on the Web.

Who’s Minding the Mind?

July 31, 2007

New studies reveal a subconscious brain that is far more active, purposeful and independent than previously known.

Goals are like neural software programs that can only be run one at a time, and the unconscious is perfectly capable of running the program it chooses.

In several studies, researchers have also shown that, once covertly activated, an unconscious goal persists with the same determination that is evident in our… read more
