Speedier Bug Catching

March 31, 2010

Engineers at Stanford University have proposed a new method called “instruction footprint recording and analysis” (IFRA) to help locate bugs in a fraction of the time normally required.

About 1 percent of the transistors on a chip are used to record a log of chip activity–the instructions that pass through the chip’s circuits. This log can be extracted from the chip, dumped into a computer, and analyzed to find… read more

WWF: Humanity Using Resources Too Fast

October 26, 2006

The Earth’s ecosystems are being run down faster than ever because humanity is using more natural resources than our planet can replenish, the World Wildlife Fund said Tuesday.

Eventually, ecological assets, such as forests and fisheries, will be harvested to such a degree that they might disappear altogether.

Project to rebuild Internet gets $12M, bandwidth

July 31, 2008

With $12 million in government funding, BBN Technologies is heading a massive project to redesign and rebuild the Internet from scratch: the Global Environment for Network Innovations (GENI), a network on which researchers will be able to test new ideas, using ultra-high-speed bandwidth(10 and 30 gigabits per second) without damaging the current Internet.

Construction on GENI could start in about five years and cost $350 million.

Self-assembling magnetic nanorings allow for nonvolatile memory

December 11, 2003
The nanorings

A Purdue research team has created tiny magnetic “nanorings” less than 100 nanometers across that can store information at room temperature, using magnetic cobalt nanoparticles that self-assemble.

The nanorings could serve as nonvolative memory for long-term data storage and random-access memory.

Solar-Powered Plane

April 9, 2010


The maiden test flight of the first ultra-lightweight experimental solar plane, the Solar Impulse, lifted off at a military airport in the Swiss countryside Wednesday.

The plane, designed by a Swiss team headed by Bertrand Piccard, has wings as wide as a Boeing 747. Equipped with 12,000 solar cells, 880 pounds of lithium batteries and four 10 horsepower electric motors, the plane weighs about… read more

New Techniques Pave Way for Carbon Nanotubes in Electronic Devices

November 8, 2006

Rensselaer Polytechnic Institute reports two new techniques, each following a different approach, for placing carbon nanotube patterns on metal surfaces of just about any shape and size.

Kites could provide electricity for 100,000 homes

August 8, 2008

High-flying kites tethered to generators could supply as much as 100 megawatts of electricity, enough to power 100,000 homes, according to researchers from the Delft University of Technology.

Some researchers estimate kites could provide more than 100 times the amount of wind energy required to power the entire planet.

Instant stem cells — just add water

December 19, 2003

Researchers are honing a technique to create dried stem cells that can be revived just by adding water. The “instant” cells might provide mobile therapies for remote regions or the battlefield.

Because some stem cells can make fresh bone, muscle or blood, doctors hope to use them to repair tissues. But, like transplant organs kept on ice, their shelf life will be limited without an easy way to store… read more

DARPA announces plans for self-piloted flying car

April 20, 2010


DARPA announced that it is inviting proposals to tackle its latest project: Transformer X, a “vertical takeoff and landing roadable air vehicle” ready for testing by 2015.

It would have a maximum payload capacity of 1,000 pounds so that it can carry four passengers and their gear, be capable of flying itself automatically, achieving an altitude of 1,000 feet, and traveling 250 miles on a single tank of fuel.… read more

Twitter gets satellite support

February 14, 2012


Twitter has struck a deal with two large satellite operators to give subscribers the ability to publish in the most remote locations in Australia and around the world.

Iridium and Thuraya satellite subscribers will be able to use Twitter in situations where they lack access to 3G networks or phone lines. Twitter suggests it could be ideal to keep people informed from war zones or in a… read more

So what’s with all the dinosaurs?

November 22, 2006

The Creation Museum – motto: “Prepare to Believe!” – will be the first institution in the world whose contents, with the exception of a few turtles swimming in an artificial pond, are entirely fake.

It is dedicated to the proposition that the account of the creation of the world in the Book of Genesis is completely correct, and its mission is to convince visitors through a mixture of animatronic… read more

Networks of the Future: Extending Our Senses into the Physical World

August 14, 2008

Los Alamos National Laboratory computer scientist Sami Ayyorgun has developed a new communication scheme for wireless sensor networks with improved connectivity, energy, delay, throughput, system longevity, coverage, and security.

Wireless sensor networks depend on small, independently powered multihop sensor “motes” to communicate.

Proponents of wireless sensor networks see a world with deployments to improve a wide range of operations. Engineers could wirelessly monitor miles of gas and oil… read more

Radio Ready to Go Digital

January 7, 2004

Digital radio receivers finally go on sale nationwide Wednesday, pairing CD-quality audio in over-the-air broadcasts with text information such as song titles, weather and news alerts.

The Search for Genes Leads to Unexpected Places

April 27, 2010

Scientists have identified thousands of genes, including those in plants, that can give rise to diseases in humans when they mutate.

Prune bad brain wiring with magnetic pulses

February 21, 2012


Zapping the brain with a weak magnetic pulse can wipe out unwanted neural connections, in mice at least.

The discovery could lead to treatment for conditions associated with abnormal neural circuitry, such as schizophrenia.

In transcranial magnetic stimulation (TMS), a magnetic coil induces electric currents in the brain that can strengthen or suppress neural connections. This technique has been shown to improve symptoms in people with brain disorders… read more
