The Wall Has Fallen: 3 Augmented Reality Apps Now Live in iPhone App Store

August 30, 2009

Three augmented reality apps (overlaying information on the camera view) have come to the iPhone, thanks to an unofficial developer workaround (Apple’s next OS, due this Fall, will support AR apps officially).

Silicon chip works on the speed of light

November 3, 2005

A silicon chip that can carry light and even slow it down by a factor of 300 has been unveiled by IBM researchers in the US.

The idea is that such a device could synchronise data streams by slowing some streams, allowing others to catch up.

The chip demonstrates some of the essential techniques for creating high-speed photonic memory, which many researchers believe will one day make electronic… read more

Google Sky Rises Above Google Earth

March 14, 2008

Google said that Google Sky, previously a star-viewing option in the Google Earth desktop application, can now be viewed on its own in a Web browser.

On the Scent of Terrorists

January 4, 2003

DARPA wants someone to develop a sniffing machine that can detect individuals by their body odor.

Applicants must, within 15 months of research, identify the specific odors produced by the immune system, whether directly or through bacterial action. After another 15 months, any confounding smells produced by stress, diet, health and age must also be catalogued. And then applicants will have two more years to develop a person-sniffer that… read more

Large-scale study probes how cells fight pathogens

September 4, 2009

Scientists have deciphered a key molecular circuit that enables the body to distinguish viruses from bacteria and other microbes, providing a deep view of how dendritic cells cells in mammals fend off different pathogens.

They found a dendritic cell circuit with two major arms: an inflammatory arm, which is highly active during bacterial infections and can initiate a system-wide immune response; and an anti-viral arm, which is induced upon… read more

World first trial grows blood vessels from patient’s own skin

November 17, 2005

Scientists have successfully implanted blood vessels grown entirely from a patient’s own cells.

The veins were created in a laboratory by scientists at Cytograft Tissue Engineering before being transplanted into patients undergoing kidney dialysis to test whether they could withstand high blood pressures.

The team is now about to embark on an unprecedented trial at Papworth hospital in Cambridge, which will see lab-grown blood vessels used in heart… read more

Singularity Summit 2008 announced

March 19, 2008

The Singularity Institute for Artificial Intelligence plans to hold Singularity Summit 2008 at the Montgomery Theater in San Jose, California on October 1825, 2008, SIAI Executive Director Tyler Emerson told

Speakers, program, and registration details will be forthcoming.

Scientists Giddy About the Grid

January 21, 2003

For years, connecting university and research-center supercomputers so they could share resources simply wasn’t feasible. New standards are changing that and opening the door to new research possibilities.

Scientists Develop Novel Use Of Neurotechnology To Solve Classic Social Problem

September 14, 2009

Cal Tech economists and neuroscientists used whole-brain fMRI scans in an experiment to create a solution to the fundamental “public goods free-rider” problem (how to fairly rate the value of a public purchase or investment such as health care, given that people tend to undervalue it because they get benefit from it without paying more).

The subjects were asked to reveal how much they valued the good. If there… read more

Nanopillars reverse optical behaviour

November 29, 2005

Scientists in the UK and Russia have succeeded in fabricating a material that has a negative permeability at visible wavelengths.

The development is important because it could lead to “left-handed” materials, which exhibit a negative refractive index and function as a perfect lens, focusing light to a smaller spot than is usually possible.

Replacing Wire With Laser, Sun Tries to Speed Up Data

March 25, 2008

Sun Microsystems is planning to announce that is has received a $44 million contract from the Pentagon to explore the high-risk idea of replacing the wires between computer chips with laser beams.

The “silicon photonics” technology would eradicate the most daunting bottleneck facing today’s supercomputer designers: moving information rapidly to solve problems that require hundreds or thousands of processors.

Doctors Review GM Crop Advice

February 10, 2003

The British Medical Association is looking again at research into genetically modified food four years after it raised safety doubts.

Plug-and-Play Medicine

September 18, 2009

Oxyimeters control an IV drug device (not shown) (CIMIT)

The Integrated Clinical Environment (ICE), a software platform for fully interoperable medical devices to better manage patients and their care, has been developed by the Center for Integration of Medicine and Innovative Technology (CIMIT), a hospital/academic consortium in Boston.

Buckyballs could disrupt functioning of DNA

December 10, 2005

Computer simulations show that buckyballs have the potential to damage DNA.

Researchers at Oak Ridge National Laboratory in Tennessee, and Vanderbilt University found that the buckyballs bind strongly to DNA, distorting the strands, which could interfere with the DNA’s function, disrupting replication and repair and increasing mutation rates.

But they cautioned that it remains to be determined if buckyballs even penetrate cell membranes, and if they do, whether… read more

Coming Soon, to Any Flat Surface Near You

March 31, 2008

Tiny digital projectors for cellphones and portable media players are in the works, able to project video on any smooth surface.

The microprojectors, still in prototype, use light-emitting diodes, lasers or a combination of the two to cast a display of up to 50 or 60 inches, or perhaps even wider, in darkened spaces and 7 to 20 inches or so when there is ambient light.

Later, the… read more
