50MP CCD Image Sensor unveiled by Kodak

July 9, 2008

Eastman Kodak Company unveiled the world’s first 50 million pixel CCD image sensor for professional photography.

The sensor captures digital images with unprecedented resolution and detail. For instance, with a 50 megapixel camera, in an aerial photo of a field 1 1/2 miles across, you could detect an object about the size of a small notebook computer (1 foot by 1 foot).

British scientists grow human liver in a laboratory

October 31, 2006

British scientists have grown the world’s first artificial liver from stem cells in a breakthrough that will one day provide entire organs for transplant.

The liver tissue was created from stem cells found in blood from an umbilical cord minutes after birth. They were then placed in a bioreactor and various hormones and chemicals were added to coax the stem cells into turning into liver tissue.

Seeing terror risk, US asks journals to cut flu study facts

December 21, 2011

A(H5N1) virus

For the first time ever, a government advisory board is asking scientific journals not to publish details of certain biomedical experiments, for fear that the information could be used by terrorists to create deadly viruses and touch off epidemics.

In the experiments, conducted in the United States and the Netherlands, scientists created a highly transmissible form of a deadly flu virus that does not normally spread from person to… read more

Broadband-deprived Cerritos turns to WiFi

December 16, 2003

The largest WiFi wireless networking deployment in the nation is planned for the entire city of Cerritos, California, providing broadband Interent access for 51,000 residents in the 8.6-square-mile area.

DSL and cable broadband access to the Internet is currently not available.

IBM Scientists Create Ultra-Fast Photonic Device for Communication between Computer Chips

March 4, 2010

IBM scientists have unveiled a “nanophotonic avalanche photodetector,” a significant step towards replacing electrical signals that communicate via copper wires between computer chips with silicon nanocircuits that communicate using pulses of light.

The device uses the “avalanche effect” in Germanium and is the world’s fastest device of its kind. It can receive optical information signals at 40Gbps (billion bits per second) and simultaneously multiply them tenfold.

Japanese boffins develop long-life Flash

July 16, 2008

Flash memory chips with a potential lifetime of hundreds of years and a lower rewriting voltage have been developed by University of Tokyo scientists.

Current Flash chips are estimated to have a useful lifetime of around a decade or less for most applications.

Electron beams shrink carbon nanotubes to order

November 14, 2006

A way to controllably shrink carbon nanotubes to a particular diameter could someday help electronics engineers build faster computers and other novel electronic devices.

An electron beam is fired at the tube to knock carbon atoms out of their honeycomb structure while a current is run through the tube to reshuffle the remaining carbon atoms back into a regular, albeit narrower, nanotube structure.

Is Nanotechnology Real?

December 23, 2003

The Drexler-Smalley debate about molecular nanotechnology may have even greater importance for undeveloped countries, according to Sam Ghandchi, Editor/Publisher of IRANSCOPE.

“Nanotechnology may replicate fuel cells to put an end to the age of oil,” he said in an editorial. “It would not only impact the economy of oil producing countries like Iran, but it can change the whole economy of energy production in the world, which is the… read more

How electricity moves through cells

March 12, 2010

Molecular Image

Researchers at the University of Minnesota have created a molecular image of a system that moves electrons between proteins in cells, obtained using x-ray crystallography.

The study could provide insights to minimize energy loss in other systems, from shrinking electronic circuitry to a more efficient electrical grid.

Enough Atoms for a Cannonball? Or Just a Small Splash?

July 22, 2008

Physicists at the University of California, Berkeley have developed a nanomechanical sensor — a cantilevered carbon nanotube — that can weigh an atom, replacing a large mass spectrometer.

The mass is determined by sending a radio-frequency signal to the nanotube and measuring its resonant frequency, which changes when different atoms are stuck to it.

New discovery of the ways cells move could boost understanding of spread of cancer

Cheekcells_stained

Led by researchers at Harvard School of Public Health (HSPH) and the Institute for Bioengineering of Catalonia (IBEC), investigators found that epithelial cells — the type that form a barrier between the inside and the outside of the body, such as skin cells — move in a group, propelled by forces both from within and from nearby cells — to fill any unfilled spaces they encounter.… read more

Store 256GB on an A4 sheet

November 27, 2006

New “rainbow technology” allows data to be encoded into colored geometric shapes and stored in patterns on paper or or plastic sheets at a density of 2.7GB per square inch and and then played back through a computer with a special scanner attached.

Optogenetics switch turns neurons on and off

January 4, 2012

Molecular combination switch: two light-sensitive membrane proteins (red and purple) are linked via a connecting piece (green) and anchored into the cell wall (left). When the cell is illuminated with blue light, it allows positively charged ions in. Orange light has the opposite effect, allowing negatively charged ions into the cell. The cell is activated or deactivated, respectively (right). (Credit: MPI of Biophysics)

A research team at the Max Planck Institute of Biophysics in Frankfurt am Main has developed a molecular light switch that makes it possible to control cells more accurately than ever before.

The combination switch consists of two different light-sensitive membrane proteins — one for on, the other for off.

Optogenetics is a new field of research that aims to control cells using light,… read more

Gates Previews ‘Amazing Decade’

January 9, 2004

Bill Gates kicked off the annual International Consumer Electronics Show on Wednesday night by touting a mix of “seamless computing experiences” inside and outside the home, driven by Microsoft technology:

  • The Windows Media Center Extender, which allows consumers to retrieve and control digital music, video and photos stored on Microsoft Media Center PCs from their TVs.
  • The portable Media Center, which is small enough to fit
