Quantum Trickery: Testing Einstein’s Strangest Theory

December 29, 2005

Experiments in quantum entanglement are increasing challenging Einstein’s critique of “spooky action at a distance.”

The world is “not as real as we think,” says Anton Zeilinger of the University of Vienna. It’s “even weirder than what quantum physics tells us.”

Cerf: streaming network crunch could be eliminated

June 24, 2011

While Internet carriers may fret about Netflix, Hulu, and other streaming media services saturating their bandwidth, Internet forefather Vint Cerf has a simple answer for this potential problem: increase bandwidth exponentially.

With sufficient bandwidth, streaming video services of prerecorded content wouldn’t be necessary, explained Cerf, who is now a technology evangelist at Google. With sufficient throughput, the entire file of a movie or television show could be downloaded in… read more

Search for the next big thing

A model that replicates the functions of the human brain is feasible in 10 years according to neuroscientist Professor Henry Markram of the Brain Mind Institute in Switzerland.

“A brain model will sit on a massive supercomputer and serve as a kind of educational and diagnostic service to society,” he said. “As the industrial revolution in science progresses we will generate more data than anyone can track or any… read more

New video series ‘Beyond the Desktop’ explores potential of 3-D printing

How additive manufacturing could transform medicine, aerospace and space travel
September 10, 2015

additive manufacturing

A five-episode video series called Beyond the Desktop that explores how additive manufacturing could affect the fields of medicine, aerospace, space technology and more has been released by the Wilson Center’s Science and Technology Innovation Program (STIP). The first episode was posted yesterday (Sept. 9); a new episode will be released each Wednesday through early October.

“Desktop 3-D printing has received significant media… read more

Silicon compound superconducts at room temperature

March 20, 2008

Max Plank Institute and University of Saskatchewan researchers have fabricated a room-temperature superconducting material that does not require cooling.

The new silicon-hydrogen compound is super-compressed, potentially allowing it to be used without super-cooling the material, as is necessary for conventional superconductors.

Researchers have speculated for years that hydrogen under enough pressure would superconduct at room temperature, but have been unable to achieve the necessary compression. The Canadian and… read more

Nanotechnology, Nanomedicine and Nanosurgery

January 10, 2006

Nanomedicine pioneer Robert A. Freitas Jr. has written a landmark paper on nanosurgery in a peer-reviewed medical journal (“Nanotechnology, Nanomedicine and Nanosurgery,” Intl. J. Surgery 3, December 2005:1-4).

Freitas describes current state-of-the-art surgery using a micropipette to completely cut dendrites from single neurons without damaging cell viability, localized nanosurgical ablation of focal adhesions adjoining live mammalian epithelial cells, microtubule dissection inside yeast cells, and even nanosurgery of… read more

Change in material boosts prospects of ultrafast single-photon detector

July 3, 2011

Single Photon

A practical way to boost the efficiency of the world’s fastest single-photon detector, while extending light sensitivity to longer wavelengths, has been found by researchers at the National Institute of Standards and Technology (NIST).

The detector, made of superconducting nanowires, can register individual photons. NIST’s new tungsten-silicon alloy version has an efficiency of 19 to 40 percent over a broad near-infrared wavelength range of 1280 to… read more

The next big thing (is practically invisible)

March 28, 2003

Nanoparticles now turn up in everyday products from tennis balls to sunscreen but some activists are calling for regulation and even a moratorium on some types of nanoscale research.

Amazing 18-Foot Wide Super-HD Multi-User Multitouch Display

September 14, 2009

Obscura Digital’s newest, longest multitouch wall has launched at the Hard Rock in Vegas, using three projectors to handle 100 hi-res images and videos simultaneously in real time.

‘Diet’ foods may not fool the brain

March 27, 2008

Duke University researchers have found that mice can detect a food’s caloric content–they prefer sugary foods even when they can’t taste sweetness.

When the sweet-oblivious mice drank sugar water, their brains produced dopamine. Calorie free–but still sweet-tasting–water sparked little dopamine production in the rodents’ brains, suggesting an innate attraction to sweet foods.

Nanostructured gel muscles in on the action

January 19, 2006

Researchers have created a nanostructured gel that can act as a synthetic muscle. The material reacts to chemical changes in its environment by expanding or contracting.

The gel consists of a polyacid matrix containing nanoscopic hydrophobic domains. The material is formed by self-assembly from a triblock copolymer.

Testing the synthetic muscle by using it to bend a soft cantilever revealed that it produced a power per unit mass… read more

Virtual bridge allows strangers in Mideast to seem less strange

July 11, 2011

Facebook.com/yalaYL 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

Beyond Wi-Fi: The 5 next big things

April 16, 2003

Ultrawideband, mesh networks, software-defined radio, wireless personal area networks, and adaptive radio are the next big things beyond WiFi networks, bringing broader geographical coverage and better use of spectrum.

Genetic seamstress uses molecular fingers to tweak DNA

September 21, 2009

Scripps Research Institute scientists have attached site-specific viral enzymes called recombinases to zinc fingers (ZFRs, proteins that bind to DNA) to accurately locate, snip, and repair DNA strands.

The new technique could lead to safer gene therapies and more effective genetic engineering.
