‘DNA wires’ promise future self-assembling computer devices

March 2, 2005

“DNA wires” may lead to low-cost, self-assembling devices for future computers.

Purdue University researchers brought together magnetic nanoparticles and DNA in solution, causing the DNA to be coated with the magnetic nanoparticles and forming a conductive “DNA wire.” They then used a BamH1 “restriction enzyme” to cause the DNA wire to be snipped in specific smaller lengths.

Because hundreds of different restriction enzymes snip segments containing specific sequences… read more

Marines want lots of robots they can throw

August 20, 2009

The US Marine Corp has a request: build and rapidly deploy 10lb or under robots its personnel can throw into dangerous situations that can quickly gather information without endangering Marines.

Virtual bridge allows strangers in Mideast to seem less strange

July 11, 2011 allows Israelis and Palestinians and other Arabs to connect.

Created by Uri Savir, a former Israeli diplomat, it has 22,500 active users; 60 percent are Arabs — mostly Palestinians, followed by Egyptians, Jordanians, Tunisians, Moroccans, Lebanese and Saudis. The YL in the name stands for young leaders (yala means “let’s go” in Arabic), and Savir said he saw the page as a place where… read more

RoboFly’s flight test

November 7, 2001

The first limited flight of the smallest-ever flapping-wing machine has been achieved by researchers at the University of California, Berkeley.

Berkeley’s RoboFly has a wingspan of just three centimeters and weighs 300 milligrams. It is modeled on a fruit fly, which flaps and rotates its wings hundreds of times per second.

The inaugural flight was just 30 centimeters and used one wing, while the robot was tethered to… read more

DARPA is pushing the boundaries of unmanned aviation to extremes, with its Vulture program to demonstrate an unmanned aircraft capable of staying aloft for five years, and its Rapid Eye, a UAV that could be rocket-deployed to anywhere in the world within hours.

Bioterror CSIs Target Germs

March 16, 2005

New bioterrorism forensic tools, including advanced mass spectrometry, chemical analysis of water, and DNA fingerprinting, could identify the region of the country where a bioagent was grown.

The Wall Has Fallen: 3 Augmented Reality Apps Now Live in iPhone App Store

August 30, 2009

Three augmented reality apps (overlaying information on the camera view) have come to the iPhone, thanks to an unofficial developer workaround (Apple’s next OS, due this Fall, will support AR apps officially).

The rational aspect of empathy

July 18, 2011

According to a new study from the University of Southern California, even failing to possess a full complement of limbs will not stop your brain from understanding what it is like for someone else to experience pain in one of them. It may, however, change the way your brain does so, the researchers have found.

They showed videos of tasks being performed by hands, feet,… read more

Advances in Quantum Computing

December 4, 2001

Quantum computing borrows ideas from finance: a balanced portfolio of programs could mean a faster quantum computer.Strategies from the world of finance could help get the best out of quantum computers, say US researchers. The right portfolio of programs could solve a problem many times faster than a single strategem.

Quantum computers – purely hypothetical as yet – would be fast, but you could never be sure whether a… read more

Google Sky Rises Above Google Earth

March 14, 2008

Google said that Google Sky, previously a star-viewing option in the Google Earth desktop application, can now be viewed on its own in a Web browser.

BlueGene/L doubles up

March 25, 2005

BlueGene/L, already number one on the latest Top 500, nearly doubled its performance — now at 135.3 teraflops — after doubling its processor count at Lawrence Livermore National Laboratory.

Large-scale study probes how cells fight pathogens

September 4, 2009

Scientists have deciphered a key molecular circuit that enables the body to distinguish viruses from bacteria and other microbes, providing a deep view of how dendritic cells cells in mammals fend off different pathogens.

They found a dendritic cell circuit with two major arms: an inflammatory arm, which is highly active during bacterial infections and can initiate a system-wide immune response; and an anti-viral arm, which is induced upon… read more

Wolfram Research has announced the Computable Document Format (CDF), a new standard to put interactivity at the core of everyday documents and empower readers with live content they can drive.

CDF is a computation-powered knowledge container. Its… read more

Observatory could detect hidden dimensions

January 9, 2002

Cosmic rays could find proof of extra dimensions by detecting tiny black holes.The Pierre Auger Observatory, currently being constructed in Argentina to study cosmic rays, could examine the structure of spacetime itself, say physicists in the United States.

If, as some suspect, the Universe contains invisible, extra dimensions, then cosmic rays that hit the atmosphere will produce tiny black holes. These black holes should be numerous enough for the… read more
