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 KurzweilAI.net.

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

New high-speed 3-D imaging system holds potential for improved cancer screening

August 1, 2011

This is a 3-D OCT volumetric data set from an excised human colon specimen. (A) En face view showing regular organization of normal colon. (B and C) Cross-sectional views along two different directions showing sub-surface features. Two cross-sections are shown as examples, however multiple cross-sectional views can be extracted from the 3-D OCT data. Scale bar: 500um (credit: Massachusetts Institute of Technology

Researchers at MIT have developed a new imaging system that enables high-speed, 3-D imaging of microscopic pre-cancerous changes in the esophagus or colon.

The new endoscopic optical coherence tomography (OCT) imaging system works at record speeds, capturing data at a rate of 980 frames (equivalent to 480,000 axial scans) per second — nearly 10 times faster than previous devices — while imaging microscopic features… 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

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.

How the brain remembers what happens and when

August 8, 2011

Neuroscientists at New York University have identified the parts of the brain we use to remember the timing of events within an episode.

The researchers ran animal subjects through a temporal-order memory task in which a sequence of two visual objects were presented and the subjects were required to retrieve that same sequence after a delay. To perform the task correctly, the subjects needed to remember… read more

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

Japan’s NEC Takes Step Forward in Quantum Computing

February 20, 2003

NEC and Japanese government-funded research group RIKEN said they had successfully created a state of quantum entanglement between two solid-state qubits for the first time. This breakthrough could bring quantum computers a step closer.

Intel’s Plan to Replace Copper Wires

September 25, 2009

(Intel)

Intel has announced plans to ship in 2010 an optical cable called Light Peak that will be able to transmit 10 gigabits of data per second between electronic devices such as a laptop and external hard drive.

A single Light Peak cable will also be capable of transporting different types of data simultaneously, meaning it will be possible to back up a hard drive, transfer high-definition video, and connect… read more

Study builds on plausible scenario for origin of life on Earth

August 15, 2011

The natural enantiomer of the RNA precursor molecules formed a crystal structure visible to the naked eye (credit: Jason Hein)

A relatively simple combination of naturally occurring sugars and amino acids formed on Earth before any life existed offers a plausible route to RNA, researchers at the University of California, Merced, have found.

Biological molecules, such as RNA and proteins, can exist as enantiomers. Enantiomers are two molecules that are identical except for the three dimensional arrangement of the atoms that make it up. One of the best… read more

How new neurons integrate into the brain

December 23, 2005

Scientists from Johns Hopkins’ Institute for Cell Engineering have discovered the steps required to integrate new neurons into the brain’s existing operations.

For more than a century, scientists thought the adult brain could only lose nerve cells, not gain them, but in fact, new neurons do form during adulthood in all mammals, including humans, and become a working part of the adult brain in mice at the very least.… read more
