Numenta is preparing to release a version of their AI technology that is ready to help companies turn a deluge of data into business intelligence.

The Brightest, Sharpest, Fastest X-Ray Holograms Yet

August 4, 2008

An international group of scientists has produced two of the brightest, sharpest x-ray holograms of microscopic objects ever made, thousands of times more efficiently than previous x-ray-holographic methods.

The two experiments demonstrate that massively parallel holographic x-ray images with nanometer-scale resolution can be made of objects measured in microns, in times as brief as femtoseconds, using a pinhole array.

By knowing the precise layout of a pinhole array,… 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.

The Business Of Nanotech

February 4, 2005

Hew nano-based products that could have a big impact are only a step or two away.

Within the next two years, diagnostic machines with components built at the nano scale should allow doctors and nurses to carry pint-size laboratories in their briefcases, perhaps to test for HIV or count white blood cells on the spot. Nano sensors will scour airports and post offices for anthrax and sarin. Toward the… read more

There’s still plenty of hype, but nanotechnology is finally moving from the lab to the marketplace.

The Cambridge Project for Existential Risk

June 29, 2012

Concerned that developments in human technology may soon pose new, extinction-level risks to our species as a whole, Astronomer Royal Martin Rees, Cambridge University philosopher Huw Price, and Skype co-founder Jaan Tallinn have formed The Cambridge Project for Existential Risk.

“These dangers have been suggested from progress in AI, from developments in biotechnology and artificial life, from nanotechnology, and from possible extreme effects of anthropogenic climate change,” the… read more

The Car That Makes Its Own Fuel

October 25, 2005

A unique system that can produce Hydrogen inside a car using common metals such as magnesium and aluminum and running on water has been developed by an Israeli company.

The system reportedly solves the obstacles associated with the manufacturing, transporting and storing of hydrogen to be used in cars. When it becomes commercial in a few years time, the system will be incorporated into cars that will cost about… read more

The case for optionally manned aircraft

Purely manned or purely unmanned aircraft possess various inherent advantages and limitations. Optionally manned aircraft provide the best of both worlds, allowing commanders to employ force at various risk levels and to employ their aircraft and crews to their fullest capacities, says Lt. Col. Peter Garretson in Armed Forces Journal.

Such platforms — and in particular, the planned Long Range Strike-Bomber (LRS-B) — represent the lowest-cost, lowest-risk path toward… read more

The cat is out of the bag: cortical simulations with 10^9 neurons, 10^13 synapses

November 18, 2009

BlueMatter, a new algorithm created in collaboration with Stanford University, exploits the Blue Gene supercomputing architecture in order to noninvasively measure and map the connections between all cortical and sub-cortical locations within the human brain using magnetic resonance diffusion weighted imaging. Mapping the wiring diagram of the brain is crucial to untangling its vast communication network and understanding how it represents and processes information. (IBM Research)

Results of massively parallel cortical simulations of a cat cortex, with 1.5 billion neurons and 9 trillion synapses, running on Lawrence Berkeley National Laboratory’s Dawn Blue Gene/P supercomputer, will be presented by IBM and LLNL researchers today at the SC09 Conference on High Performance Networking and Computing in Portland.

“The simulations, which incorporate phenomenological spiking neurons, individual learning synapses, axonal delays, and dynamic synaptic channels,… read more

The Cell Hijackers

May 19, 2004

Soon, our knowledge of life processes will let us program cells as we do computers, says Rodney Brooks.

This engineering revolution is coming to be known as synthetic biology. Examples include modifying protein production processes to turn E. coli cells into primitive digital computers; the creation of cells that are genetically altered to deliver drugs within a person’s body; programming a cell to sense blood sugar levels and produce… read more

The Cellphone, Navigating Our Lives

February 18, 2009

With the dominance of the cellphone, the map is emerging as a new metaphor for how we organize, find and use information.

A new generation of smartphones like Google’s Android G1 and a range of Japanese phones now “augment” reality by painting a map over a phone-screen image of the user’s surroundings produced by the phone’s camera.

With this sort of map it is possible to see a… read more

The CEO’s Tech Toolbox

July 26, 2005

Podcasts, RFID tags, and mesh networks are among the 10 new technologies that should be on the radar of every chief exec.

For example, IBM is developing AI-based software called the Uber-Personal Assistant (UPA). It will analyze your schedule, e-mails, and the text you’re typing to figure out exactly what you’re working on. Then, it will alert you to new e-mails pertinent to that project.

The cerebellum as navigation assistant

November 7, 2011

The cerebellum is far more intensively involved in helping us navigate than previously thought.

To move and learn effectively in spatial environments, “place cells” in the hippocampus, create a cognitive map of the environment through the integration of multisensory inputs combining external information (such as visual, auditory, olfactory and tactile cues) and inputs generated by self-motion (optic flow, and proprioceptive and vestibular information)..

The cerebellum contributes… read more

The Challenge of Molecular Communication

June 28, 2010

Emulating the efficient way that bacteria communicate with molecules, computer scientists are developing a mathematical theory of molecular communication based on a wetware model that includes quorum sensing and factors such as Brownian motion, the velocity of fluid flow, and the rate of molecular diffusion.

The Chaos Inside a Cancer Cell

December 26, 2008

Baylor College of Medicine in Houston have now compared the genome of a type of breast cancer cell with that of normal cells. They find 157 rearrangements. The impairment of double strand break repair could be a major cause of all the other rearrangements, the researchers suggest.
