The Power Of Plant Clock Computing

March 1, 2010

Stochastic process algebra, which encompasses concurrent processes and the communication between them, could lead to a new generation of super-efficient computing.

Process algebra, which is being used by UK scientists for computation of the complex biochemical processes that drive the circadian clock of a plant, is potentially more powerful by several orders of magnitude than sequential Turing machine-based computing processes.

Smart TVs: the next tech war is in the living room

January 13, 2012


At the Consumer Electronics Show (CES), the world’s top television manufacturers are proposing a whole new approach to television:

  • Samsung is working on integrating voice and motion control into its new TV sets, enabling users to speak commands to their TVs or change channels and other settings with just a wave.
  • Vizio has joined with cloud-service company OnLive to put streaming games on its Google

Renewing a Call to Act Against Climate Change

March 14, 2007

Bill McKibben, who was one of the first laymen to warn of global warming, is now the philosopher-impresario of the program of climate-change rallies called Step It Up.

High Cost of Driving Ignites Online Classes Boom

July 14, 2008

Thousands of students nationwide have suddenly decided to take one or more college classes over the Internet, as fuel for commuting to campus now costs some students half of what they pay for tuition, in some cases more.

Search engine tackles tricky lists

May 10, 2004

KnowItAll, a search engine under development at the University of Washington, trawls the web for data and then collates it in the form of a list.

It solves the problem of finding information (such names of scientists in a specific field) that probably does not exist on any single web page.

Exclusive: Colorado Doctors Skirt FDA Jurisdiction to Provide Stem Cell Therapies

March 10, 2010

Regenerative Sciences in Broomfield, Colorado provides its patients with the Regenexx procedure, an adult stem cell transplant that uses your own cells (autologous) to treat joint injuries and bone damage.

Human stem cell therapies like this one aren’t approved by the FDA.

Bitcoin online currency gets new job in web security

January 19, 2012


Bitcoin software could prove at least as useful as the Bitcoin online peer-to-peer currency itself by underpinning a number of important new technologies:

  • A form of “carbon dating” for digital information — something that would make electronic voting more secure,  because of the way Bitcoin records transactions.
  • Namecoin, which uses modified Bitcoin software to provide decentralized domain names for websites, could be used

Wiki used to plan wind-turbine locations

March 22, 2007

A wiki is being used in the Netherlands to plan wind turbines. The wiki, extended with a Google Maps plugin, presents maps with proposed wind turbine locations. The goal is to decide on locations for 6000 3-MegaWatt turbines, enough to provide for all electricity in the Netherlands.

When a design has gained enough support, it can become a real wind energy project, and move on to official… read more

The Bubble Bursts

July 20, 2008

A Purdue University nuclear engineer who claimed to have carried out tabletop nuclear fusion is responsible for two instances of scientific misconduct, a report made public today concludes. Both cases centered on efforts by physicist Rusi Taleyarkhan to make experiments carried out by members of his lab appear as independent verification of his work.

Researchers demonstrate wearable electronics to aid health and fashion

May 18, 2004

Arizona State University researchers have developed a “biometric bodysuit” using integrated and embedded electronic sensors, printed organic opto-electronics, power sources, microfluidic devices, and pumps in clothes.

The “Scentsory Chameleon Bodysuit” acts as a “smart second skin” to enable real-time remote personal health and medical monitoring.

A military camouflage version includes pathogen detectors, flexible electroluminescent display, and a high-density, low-temperature micro fuel cell that acts as a lightweight, long-life… read more

GM Develops Augmented Reality Windshield

March 18, 2010

A future “enhanced vision system” from General Motors could help drivers by highlighting landmarks, obstacles and road edges on the windshield in real-time.

It uses a special type of glass coated with red-emitting and blue-emitting phosphors–a clear synthetic material that glows when it is excited by ultraviolet light.


What if Humans were Designed to Last?

March 30, 2007

Experts across fields were challenged to imagine a new way to solve the problems of human aging by fiddling with physiology and tinker with the inner mechanics of life at the cellular or even molecular level.

Microsoft Engineers Invent Energy-Efficient LCD Competitor

July 25, 2008
Telescopic pixels (Anna pyayt)

Microsoft researchers have built a prototype display technology that mimics the optics in a telescope (at the scale of individual display pixels), with results that are faster and more efficient than a liquid crystal display (LCD).

LCD, the most common display technology, is lit from the back, and less than 10 percent of the light reaches the surface of the screen.

The new telescopic pixel design… read more

Interview: Abrupt Climate Change, the Pentagon, and The Day After Tomorrow

June 1, 2004

Doug Randall, who co-authored “the Pentagon study” on abrupt climate change, has commented on the “Day After Tomorrow film.

“The timeframe is definitely exaggerated, but the premise is one of the real issues of our day,” he said. “The danger signs come from the world of science and have to do with things like salinity of the Atlantic Ocean and the thermohaline conveyor. Signs that point to big shifts… read more

Playing ‘Pong’ with the blink of an eye

March 29, 2010


An inexpensive system that uses special glasses that contain an infrared light, webcam that detects eye movements, and computer has been developed by Imperial College London students to control a video game (Pong).

The system could be adapted to create more sophisticated games and applications such as controlling wheelchairs and computer cursors, allowing people with severe physical disabilities to become gamers and communicate.
