F.C.C. Begins Rewriting Rules on Delivery of the Internet

February 13, 2004

The Federal Communications Commission began writing new rules today that officials and industry experts said would profoundly alter both the way the Internet is delivered and used in homes and businesses.

Commissioners are writing regulations to enable computer users to gain access to the Internet through electric power lines and to allow for new Internet phone services with fewer regulatory burdens than traditional phone carriers.

Over the Horizon: Computing beyond Silicon

April 20, 2010

Researchers are getting ready for the next paradigm beyond Moore’s law by developing alternate materials such as gallium arsenide, graphene, and carbon nanotubes.

‘Slow’ light to speed up the net

August 14, 2008

A huge increase in the speed of the Internet could be produced by using metamaterials to replace the bulky and slow electronics that do the routing of information carried on fiber cables, say researchers at University of California, Berkeley and the University of Oxford.

Metamaterials could be used to temporarily store light signals, with different delays for different light frequencies, achieving an “all-optical network.”

Computers Join Actors in Hybrids On Screen

January 9, 2007

James Cameron’s 2009 Avatar film will test new 3D hyrid technologies, combining live actors and digital technology to make a large cast of virtual creatures who convey emotion as authentically as humans.

Their bodies will be filmed using the latest evolution of motion-capture technology while the facial expressions will be tracked by tiny cameras on headsets that will record their performances to insert them into a virtual world.… read more

World Awaits More GM Crops as Safety Debate Rages

February 24, 2004

The global sowing of genetically modified (GM) crops will continue rising in the next few years, gaining more of a foothold in the world’s food supply, but millions still need convincing that the food is safe to eat.

Deadly New Russian Weapon Hides In Shipping Container

April 27, 2010

A Russian company is marketing a devastating new $10-20 million cruise missile system that can be hidden inside a shipping container, giving any merchant vessel the capability to wipe out an aircraft carrier.

Potential customers for the formidable Club-K system include Kremlin allies Iran and Venezuela, say defense experts. They worry that countries could pass on the satellite-guided missiles, which are very hard to detect, to terrorist groups.

Debate rages over free wireless spectrum

August 19, 2008

The debate over new unlicensed spectrum the FCC is considering opening up is heating up with Google’s launch of a new site called FreetheAirWaves.com.

Google and other technology companies such as Intel, Microsoft and Motorola have been lobbying the FCC to open up the “white space” spectrum (slivers of spectrum between TV channels) for unlicensed use after the digital TV transition early next year, to provide broadband wireless services.… read more

A promising new direction for organ regeneration and tissue repair

Promising effects for liver, kidney and lung regeneration and wound healing
August 2, 2013

Liver regeneration

Most human tissues do not regenerate spontaneously. But now, researchers have identified an entirely new approach to enhance normal tissue growth, a finding that could have widespread therapeutic applications, according to a team led by investigators at Beth Israel Deaconess Medical Center (BIDMC) and Dana-Farber/Boston Children’s Cancer and Blood Disorders Center.

Their findings were published in the Proceedings of the National Academy of Sciences (PNAS)read more

New nano-detector very promising for remote cosmic realms

January 18, 2007

The “hot electron bolometer” (HEB), a superconducting detector of terahertz radiation developed at Delft University of Technology’s Kavli Institute of Nanoscience, offers astronomers important new information about the birth of star systems and planets.

Nanowires vie with carbon tubes for next-gen transistors

March 9, 2004

With so many stories heralding the merits of carbon nanotubes as the channels of next-generation nanoscale transistors, you’d think the case was closed. Not so, say researchers, who claim nanowires can create better nanoscale transistors — ones that can be placed more accurately, can use application-specific doping, and can be more easily integrated with traditional silicon processing.

Stephen Hawking: How to build a time machine

May 5, 2010

“I do believe in time travel,” says Stephen Hawking. “Time travel to the future, not the past” (which would violate causation).

After dismissing wormholes (don’t last long enough) and black holes (dangerous, too far away), he settles for travelling at near the speed of light by going into space.

“At 99 per cent of the speed of light, a single day on board is a whole year of… read more

Very Long-Term Backup

August 26, 2008

The Long Now Foundation has developed a modern Rosetta Stone — a backup of human languages that future generations might cherish — etched on a 3-inch nickel disc with an estimated lifespan of 2,000 to 10,000 years.

The disc contains an archive of 13,500 scanned pages in more than 1,500 human languages with human-readable scripts, text, and diagrams (using a microscope). The plan is to replicate the disc and… read more

Adult stem cells can at least make blood

January 26, 2007

Transplanted “multipotent” adult progenitor cells (MAPCs) from bone marrow were able to form all blood cell types in mouse experiments.

NASA figuring out ways to decipher silent speech

March 18, 2004

Scientists at NASA’s Ames Research Center are able to pick up the nerve signals that trigger tiny muscle movements and turn them into commands that drive a model rover or perform a simple Web search.

Although the work is very preliminary, it could someday be used in voice recognition systems and to help people communicate clearly in noisy environments. It could also help people who have lost their ability… read more

Magnetically Induced Hallucinations Explain Ball Lightning, Say Physicists

May 12, 2010

Rapidly changing fields associated with repeated lightning strikes are powerful enough to cause phosphenes (images of luminous lines and balls, or “ball lightning”), similar to the effects of transcranial magnetic stimulation (TMS), say University of Innsbruck physicists.
