Switching device enables ultrafast quantum Internet

March 23, 2011

Researchers have developed a new switching device that can route quantum bits at very high speeds along a shared network of fiber-optic cable without losing the embedded entanglement information, says Prem Kumar, AT&T Professor of Information Technology at Northwestern University.

The researchers used pairs of polarization-entangled photons emitted into standard telecom-grade fiber. One photon of the pair was transmitted through the all-optical switch. Using single-photon detectors,… read more

At Los Alamos, Two Visions of Supercomputing

June 25, 2002

Heat may be a limiting factor to Moore’s law. By 2010, scientists predict, a single chip may hold more than a billion transistors, giving off 1,000 watts of thermal energy — far more heat per square inch than a nuclear reactor.

Already, Los Alamos National Laboratory’s 30-teraops Q computer, designed to provide full-scale, three-dimensional simulation of the physics involved in a nuclear explosion, will require 5 megawatts of energy.… read more

An efficient system for delivering siRNA into primary cells to allow for future personalized cancer treatment has been developed by researchers at the University of California, San Diego School of Medicine.

Toward A Rosetta Stone For Microbes’ Secret Language

January 2, 2008

Scientists are on the verge of decoding the special chemical language that bacteria use to “talk” to each other, British researchers report.

The research could lead to new treatments for antibiotic-resistant bacteria, including “superbugs” that infect more than 90,000 people in the United States each year.

Television That Leaps Off the Screen

July 10, 2005

The first rear-projection, no-glasses 3-D television set has been developed by Deep Light of Santa Monica, CA.

“HD3D” television sets, with 1,280 lines of resolution, could be available by next year for $10,000, according to Deep Light’s co-founder Dan Mapes.

The design also uses multiple “blades” of video to enable one screen to show different programs to different viewers at the same time.

Ebola virus could be synthesised

July 18, 2002

The technique used to create the first synthetic polio virus, revealed last week, could be also used to recreate Ebola or the 1918 flu strain that killed up to 40 million people, according to experts.

The real worry is that bioterrorists could use the method to recreate viruses such as Ebola and smallpox.

Research team finds important role for junk DNA

May 22, 2009

Researchers from Princeton University and Indiana University have found that “junk” DNA may actually perform essential functions.

Genes called transposons in the single-celled pond-dwelling organism Oxytricha produce cell proteins known as transposases, which influence hundreds of thousands of DNA pieces to regroup. Organisms with these genes removed failed to develop properly.

Human Hormone Blocker Found To Help Prevent Obesity And Diabetes

January 7, 2008

Injecting obese mice with a gastric inhibitory polypeptide (GIP) blocker–found in the human body–resulted in weight loss, improved insulin resistance and reversed diabetes.

The daily injections of (Pro3) GIP countered the effects of a high-fat diet even in mice with well-established obesity and diabetes.

This study by University of Ulster and University of Copenhagen researchers may result in new approaches to treating obesity.

Google spans entire planet with GPS-powered database

September 20, 2012


Wired Enterprise reports that Google has published a research paper (open access) detailing Spanner, which Google says is the first database that can quickly store and retrieve information across a worldwide network of data centers while keeping that information “consistent” — meaning all users see the same collection of information at all times.

Spanner borrows techniques from some of the other massive software platforms Google built for its data centers,… read more

Bionic Knee Hits Market

July 25, 2005

A new prosthetic knee, developed using MIT research, is the first to use AI-based sensors that analyze the knee 1,000 times per second, allowing it to adjust to any step or misstep.

Black hole theory suggests light is slowing

August 9, 2002

Observations of the light from distant, superbright galaxies suggest that the “fine structure constant” was slightly smaller 10 billion years ago, which implies that the speed of light has decreased over time, according to Paul Davies of Macquarie University in Sydney.

If proved right, this would challenge the theory of relativity and the theory of inflation, which says space expanded extremely rapidly in the first split second after the… read more

Microsoft Bing: Much better than expected

May 29, 2009

Microsoft’s renamed Bing search engine uses technology from Powerset to display “related searches” and groups search results into categories such as product reviews, movie listings, weather, travel, and stock prices, among other new features.

Robots Need a Sensitive Touch

January 11, 2008

Robots could mean real business when they get arms and hands that mimic the dexterity and sensitivity of humans, said Tandy Trower, general manager of Microsoft’s robotics group.

The hardware needed for that may be available in five years, but the real challenge will be in programming the robot, Trower said. Software that allows robots to figure out surface textures and identify objects will require many lines of complex… read more

Drugs could head off a flu pandemic — but only if we respond fast enough

August 4, 2005

If a strain of avian influenza emerges that can spread easily from person to person, could rapid deployment of antiviral drugs stop a local outbreak from becoming a global disaster?

Yes, conclude the most detailed modelling studies yet of an emerging pandemic — if the world can muster its scientific and logistical efforts quickly enough.

Yes, congenital blind can learn to link vision and touch

April 12, 2011

Sense of Touch

Researchers at MIT have shown that the brain does not have an innate ability to connect different types of sensory input, but can quickly learn to do so.

The researchers tested five children with treatable forms of blindness to answer the question: could they visually distinguish between objects that they could previously only identify by touch? This question was first raised by scientist William Molyneux… read more
