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

A New Family of Molecules for Self-Assembly: The Carboranes

March 25, 2009

Researchers at Penn State and the Sigma-Aldrich company have found a way to control geometry and stability in making a self-assembled monolayer (SAM) of molecules on a surface by making SAMs out of different carboranethiol isomers, which are cage-like molecules.

These SAMs can selectively capture biomolecules from complex mixtures, for example.

A new form of carbon: ‘grossly warped nanographenes’

Contorted sheets of graphene alter physical, optical and electronic properties of new material
July 17, 2013

Chemists at Boston College and Nagoya University in Japan have synthesized the first example of a new form of carbon. The new material consists of multiple identical pieces of "grossly warped graphene," each containing exactly 80 carbon atoms joined together in a network of 26 rings, with 30 hydrogen atoms decorating the rim. Because they measure slightly more than a nanometer across, these individual molecules are referred to generically as "nanocarbons."</p>

A new high-resolution method for imaging below the skin using a liquid lens

February 21, 2011

This prototype device may eliminate the need for many biopsies to detect skin cancer. (J. Adam Fenster)

University of Rochester optics professor Jannick Rolland has developed an optical technology that provides unprecedented images under the skin’s surface.

The aim of the technology is to detect and examine skin lesions to determine whether they are benign or cancerous without having to cut the suspected tumor out of the skin and analyze it in the lab. Instead, the tip of a roughly one-foot-long cylindrical probe is placed in… read more

A new form of graphene oxide could be the ultimate protective coating and could have a significant impact on chemical, pharmaceutical, and electronic industries, according to University of Manchester researchers.

For example, applied as paint, it could provide an ultra-strong, non-corrosive coating for a wide range of industrial applications.

Besides being protective, the new material is mechanically nearly as tough as graphene itself, the strongest known… read more
