What Comes After Web 2.0?

December 4, 2006

Today’s primitive prototypes show that a more intelligent Internet is still a long way off.

Most of the current projects are so far from producing practical tools–let alone services that could be commercialized–that it’s premature to say they represent a “third generation” of Web technology. For that, judging from today’s state of the art, we’ll need to wait another few years.

Living view in animals shows how cells decide to make proteins

December 4, 2006

Scientists at Duke University Medical Center have visualized in a living animal how cells use a critical biological process to create unique and varied proteins.

The findings also may offer insight into a number of diseases, including cancer, in which the genetic process — called alternative splicing — goes awry and produces the wrong proteins.

Hawking says humans must look to outer space if race is to survive

December 1, 2006

Humans will have to colonize planets in far-flung solar systems if the race is to survive, renowned physicist Stephen Hawking said.

Because there are no other planets like Earth in our own solar system, Hawking said humans will have to travel to another star to find a hospitable planet to colonize. At the speed of chemical-propelled rockets like the Apollo, the trip to the next nearest star would take… read more

How to Shrink a Carbon Nanotube

December 1, 2006

A research group has devised a way to control the diameter of a carbon nanotube — down to essentially zero nanometers.

This useful new ability, designed by scientists from the University of California at Berkeley and Lawrence Berkeley National Laboratory, may help carbon nanotubes become more easily incorporated into new technologies.

Carbon globules in meteorite may have seeded Earth life

December 1, 2006

Life on Earth may have started with the help of tiny hollow spheres that formed in the cold depths of space, a new study suggests. The analysis of carbon bubbles found in a meteorite shows they are not Earth contaminants and must have formed in temperatures near absolute zero.

Online world as important to Internet users as real world?

November 30, 2006

The 2007 Digital Future Project found that 43 percent of Internet users who are members of online communities say that they “feel as strongly” about their virtual community as they do about their real-world communities.

The 2007 Digital Future Project found that Internet use is growing and evolving as an instrument for personal engagement — through blogs, personal Web sites, and online communities.

Bio-inspired Assembly of Nanoparticle Building Blocks

November 30, 2006
V-shaped amphiphilic molecules containing gold nanoparticles form cylindrical micelles when exposed to water

Chemists at Rice University have discovered how to assemble gold and silver nanoparticle building blocks into larger structures based on a novel method that harkens back to one of nature’s oldest known chemical innovations — the self-assembly of lipid membranes that surround every living cell.

Researchers believe the new method will allow them to create a wide variety of useful materials, including extra-potent cancer drugs and more… read more

Bye Swarmbots, Hello Swarmanoids

November 30, 2006

A team at the Free University of Brussels in Belgium is embarking on a 42-month research project to build and test a 60-strong swarm of small, autonomous robots — the swarmanoid — capable of collaborating in 3-D environments.

The 2006 SCIENTIFIC AMERICAN 50 special issue, December 2006, profiles the technology leaders of the year.

Unique Marvel of Ancient Greek Technology Gives Up New Secrets

November 30, 2006

The most sophisticated mechanical device of ancient Greece may finally be giving up its secrets.

Researchers have long known the so-called Antikythera mechanism was a calendar of sorts that represented the positions of the sun and moon using a series of gears. In its complexity it outshined all other objects for a thousand years following its creation sometime around the first century B.C.

Now an international consortium of… read more

Metamaterial bridges the terahertz gap

November 30, 2006

Researchers have used an artificially-structured “metamaterial” to build a device that can control highly-elusive terahertz (THz) radiation. The modulator is claimed to be ten times better at switching a THz beam than previous designs and could pave the way for the use of the radiation in a wide range of applications in chemistry, astronomy and even airport security.

Google: ‘iPod will hold all the world’s TV in 12 years’

November 29, 2006

Nikesh Arora, Google’s VP of European operations, said that in the coming years, the plummeting price of storage and its increasing volume-to-size ratio will give iPods almost unlimited potential to hold music and video.

Arora believes mobile is likely to follow the same path.

Acoustic sensors make surfaces interactive

November 29, 2006

Tai-Chi (Tangible Acoustic Interfaces for Computer-Human Interaction), a series of acoustic sensors that turn any surface into a touch-sensitive computer interface, has been developed by European researchers.

Two or more sensors are attached around the edges of the surface. These pinpoint the position of a finger, or another touching object, by tracking minute vibrations. This allows them to create a virtual touchpad, or keyboard, on any table or wall.

The Future of War

November 29, 2006

Technology will increasingly allow the most sophisticated and best equipped militaries — primarily that of the US — to fight battles using robots rather than soldiers.

Ideas on the drawing board or in development include killer satellites that could destroy an enemy’s satellites, a Common Aero Vehicle (CAV) that could swoop with hypersonic speed up to 3,000 miles to attack a target, Hyper-Velocity Rod Bundles that would fire tungsten… read more

Over 500 Million Mobile Broadband Users by 2010

November 29, 2006

Strategy Analytics has forecast 500 million mobile broadband users globally by 2010.

“We’re not likely to see technologies like mobile WiMAX or indeed, anything else, really take off until the next decade,” comments Sara Harris, Senior Industry Analyst at Strategy Analytics and author of this report. “However, HSPA and EV-DO will be more than acceptable for most users, giving them the speed and flexibility they want to use their… read more
