A neural net that diagnoses epilepsy

April 29, 2009

Texas Tech University researchers have developed a way to automatically diagnose epilepsy with an accuracy rate of 94 percent, by training a neural network to recognize the characteristic patterns in EEG data that indicate the patient is epileptic.

A neuromorphic-computing ‘roadmap’

April 22, 2014

Professor Jennifer Hasler displays a field programmable analog array (FPAA) board that includes an integrated circuit with biological-based neuron structures for power-efficient calculation.  Hasler’s research indicates that this type of board, which is programmable but has low power requirements, could play an important role in advancing neuromorphic computing. (Credit: Rob Felt)

Electrical engineers at the Georgia Institute of Technology have  published a roadmap that details innovative analog-based techniques that they believe could make it possible to build a practical neuromorphic (brain-inspired) computer while minimizing energy requirements.

“A configurable analog-digital system can be expected to have a power efficiency improvement of up to 10,000 times compared to an all-digital system,” said Jennifer Hasler, a professor in the Georgia… read more

A new — and reversible — cause of aging

NAD, a naturally produced compound in cells, rewinds aspects of age-related demise in mice
December 20, 2013

sirt1_protein

Researchers have discovered a cause of aging in mammals that may be reversible: a series of molecular events that enable communication inside cells between the nucleus and mitochondria.

As communication breaks down, aging accelerates. By administering a molecule naturally produced by the human body, scientists restored the communication network in older mice. Subsequent tissue samples showed key biological hallmarks that were comparable to those of much younger animals.… read more

A new 3D view of DNA

March 13, 2012

A 3-D image that shows how DNA packs itself tightly into a structure known as a “fractal globule.” The structure is unique in that the genome is completely unknotted, meaning, that “despite how densely it’s packed, you can pull on it, easily get to the region you want to transcribe, read it off, and put it back when you’re done,” explained Erez Lieberman Aiden (credit: Miriam Huntley, Rob Scharein, and Erez Lieberman-Aiden)

A new imaging technique is giving scientists their first three-dimensional view of the human genome,

The finding, by Erez Lieberman Aiden, a Junior Fellow of the Society of Fellows, working with Nynke van Berkum, Louise Williams, and a team of researchers from the Broad Institute of Harvard and MIT and the University of Massachusetts Medical School, suggests that how DNA is packed into cells may be at least… read more

A New Approach to Combatting HIV

March 6, 2008

University of Michigan researchers have developed nanoemulsion vaccines–made up of tiny soybean oil droplets suspended in water, studded with bits of pathogenic organisms, and swabbed into the nose–that may be the vaccines of the future.

Previously proved effective against influenza and anthrax, they have now been shown to generate immunity to smallpox and HIV in mice.

A New Approach to Fusion

July 31, 2009

General Fusion says it can build a prototype fusion power plant within the next decade and do it for less than a billion dollars, using using relatively low-tech, mechanical brute force and advanced digital control technologies, instead of expensive superconducting magnets or powerful lasers.

A new approach to SETI: targeting alien polluters

July 24, 2014

In this artist's conception, the atmosphere of an Earth-like planet displays a brownish haze - the result of widespread pollution. New research shows that the upcoming James Webb Space Telescope potentially could detect certain pollutants, specifically CFCs, in the atmospheres of Earth-sized planets orbiting white dwarf stars.

We might be able to spot extraterrestrial civilizations if we assume they spew industrial pollution into the atmosphere, say theorists at the Harvard-Smithsonian Center for Astrophysics (CfA).

Conversely, ET could spot us.

The team suggests that under ideal conditions, the upcoming James Webb Space Telescope (JWST) should be able to detect two kinds of chlorofluorocarbons (CFCs) — aerosols and ozone-destroying chemicals used in solvents.… read more

A New Approach to Treating Alzheimer’s

May 12, 2008

Neurosurgeon Andres Lozano at the University of Toronto is testing electrical stimulation of the hypothalamus as a novel treatment for Alzheimer’s disease.

A New Arms Race to Build the World’s Mightiest Computer

August 19, 2005

A global race is under way to reach the next milestone in supercomputer performance, many times the speed of today’s most powerful machines.

But the fastest American machines are used primarily for military applications at the nation’s weapons laboratories. Many scientists and technology executives in the United States are concerned about losing out in crucial markets like oil and gas exploration, automobile design and manufacturing unless they, too, have… read more

A new battery that’s cheap, clean, rechargeable, and organic

Could pave the way for renewable energy sources to make up a greater share of a country's energy generation by economically storing energy at night
July 3, 2014

USC professor Sri Narayan's research focuses on the fundamental and applied aspects of electrochemical energy conversion and storage to reduce the carbon footprint of energy use and by providing energy alternatives to fossil fuel (credit: USC Photo/Gus Ruelas)

Scientists at USC have developed a water-based organic battery that is long-lasting and built from cheap, eco-friendly components (no metals or toxic materials).

The new battery is intended for use in power plants, where it could make the energy grid more resilient and efficient by creating a large-scale means to store energy for use as needed.

“The batteries last for about 5,000 recharge cycles, giving them an estimated… read more

A New Company to Focus on Artificial Intelligence

March 24, 2005

Palm Computing co-founders Jeff Hawkins and Donna Dubinsky will announce today the creation of Numenta, a technology development firm that will conduct research in an effort to extend Mr. Hawkins’s AI theories, described in his book “On Intelligence: How a New Understanding of the Brain Will Lead to the Creation of Truly Intelligent Machines.”

Hawkins is demonstrating a pattern-recognition application using a version of his software. It allows a… read more

A New Cryptography Uses the Quirks of Photon Streams

November 4, 2002

MagiQ Technologies plans to offer a cryptogaphy system using quantum key distribution in 2003.

Keys to the code are transmitted as a stream of photons, sent over a fiber optic cable. Security is based on quantum physics: observing the transmission would alter the photons, rendering their information useless to any eavesdroppers.

A New Dimension for Your Photos

April 27, 2007

A new Web service called Fotowoosh promises to convert photos into 3-D and serve as “a 3-D Flickr.”

The technology wsa developed by computer-vision researchers at Carnegie Mellon University.

A new dimension in breast cancer research

January 9, 2012

Epithelial-Cells

A new imaging technology under investigation at the Biodesign Institute at Arizona State University may help researchers pinpoint subtle aberrations in cell nuclear structure, the molecular biosignature of cancer, thus significantly improving diagnostic accuracy and prognosis by providing early detection of breast cancer, a leading worldwide health concern.

The team has examined normal, benign and malignant cells, using the Cell-CT  from VisionGate, Inc., Phoenix, AZ,… read more

A New Face: A Bold Surgeon, an Untried Surgery

July 26, 2005

Dr. Maria Siemionow of the Cleveland Clinic is planning to undertake what may be the most shocking medical procedure to occur in decades: a face transplant.

Her team has managed to induce long-term tolerance to hind-leg transplants with a drug regimen lasting only seven days. If similar results can be achieved in humans (many previous efforts along these lines have failed), the advance will alter the calculus behind transplantations,… read more
