Mathematical model for cell signaling developed

May 28, 2004

A new mathematical model will help researchers understand “cell signaling” and learn how single atoms travel along the circuitous pathways in a cell. It may allow researchers to study biochemistry at the atomic level.

The model is a new approach to look at percolation — the flow of a liquid or small particle through a porous material. In the simulation, materials pass through fields of complex, three-dimensional shapes.… read more

Detecting cancer by scanning surface veins

September 7, 2007

A new technology for cancer detection that eliminates the need for drawing blood has been developed by Purdue University researchers.

By shining a laser on surface veins, such as those on the wrist and inside the cheek, researchers are able to reveal and count circulating tumor cells. In addition to being less invasive, the new detection method is able to evaluate a much larger volume of blood… read more

Beaming Up 3-D Objects on a Budget

April 5, 2007

Laser scanners with arrays of cameras can create digital models of objects that encode all the significant bumps, cracks, corners and facets of real things.

The world is just beginning to grapple with the implications of this relatively low-cost duplicating method, often called rapid prototyping. Hearing aid companies, for instance, are producing some custom-fitted ear pieces from scanned molds of patients. Custom car companies produce new parts for classic… read more

New Company Looks to Produce Space Based Solar Power Within a Decade

Space Energy, Inc. says they have developed a “a rock-solid commercial platform” and should be able to provide commercially available space-based solar power within a decade.

The Brain Starts to Change at Age 40

June 11, 2004

Researchers at Children’s Hospital in Boston and Harvard Medical School report that aging brains show significant differences in the behavior of several groups of genes that are important for brain function and that may contribute to the aging process.

One group of the genes plays a role in “synaptic plasticity” — the ability of the brain to make new connections so critical to learning and memory. Another group of… read more

New carbon nanotube technology to reduce large-scale emissions

September 19, 2007

A novel technology to trap large-scale greenhouse gas emissions is being developed by University of Queensland researcher Dr. John Zhu.

He aims to develop a carbon nanotube membrane for gas separation that will work like a sieve to separate high volumes of methane or carbon dioxide from other gases. The methane could also be used to provide valuable pipeline-quality gas.

Dr Zhu said that the CNT technology would… read more

New Laws of Robotics proposed for US kill-bots

April 16, 2007

Updating Isaac Asimov’s three laws of robotics, a new set of laws has been proposed to govern operations by killer robots.

John S. Canning, an engineer at the US Naval Surface Warfare Center, proposes that robot warriors should be allowed to mix it up among themselves freely, autonomously deciding to blast enemy weapon systems, but permission from a human operator should be sought for targeting humans.

$100 Genome

February 27, 2009

BioNanomatrix is pursuing what may be the key to personalized medicine: sequencing technology so fast and cheap that an entire human genome can be read in eight hours for $100 or less.

Cancer Drugs Aim at More Targets

June 25, 2004

In a “cluster bomb” approach, drug companies are doing clinical trials of a new generation of cancer drugs that can attack cancer cells on multiple fronts and come in the form of pills, whereas most cancer drugs are delivered intravenously.

But some worry about side effects of the new therapy.

Google testing “My World” for launch later this year

September 26, 2007

Rumors of Google’s plans to create a virtual world that rivals that of Second Life have popped up once again.

It would be a 3D social network tied into Google’s current applications of Google Earth and Google Maps.

A virtual world is a natural progression of Google Earth. Users could create avatars. The “street view” feature of Google Maps could be incorporated, as well as Google SketchUp, with… read more

Nanotechnology offers hope for spinal cord, diabetes, Parkinson’s

April 24, 2007

After being exposed to bioactive nanostructures developed in Samuel I. Stupp’s laboratory at Northwestern University, Mice recovered from the symptoms of Parkinson’s disease and recovery of heart function after an infarction.

Stupp and his coworkers designed molecules with the capacity to self-assemble into nanofibers once injected into the body with a syringe. When the nanofibers form they can be immobilized in an area of tissue where it is necessary… read more

Shocking cancer treatment may also yield weapon

March 5, 2009

A technique using 60-nanosecond pulses thought to be a promising cancer treatment is also being investigated by Old Dominion University as the basis for a Taser-like weapon that stuns for longer.

Digital Image Sensor

July 8, 2004

In North America, digital cameras may nearly replace film cameras by 2008, according to InfoTrends/CAP Ventures. The trend is being fueled partly by improvements in the digital sensors that capture images in lieu of film.

The latest: the X3 from Santa Clara, CA-based Foveon. It has three layers of silicon, as opposed to one in conventional sensors, which produce sharper, truer-colored photos.

Foveon partnered with Polaroid and this… read more

50 Years Later, a New ‘Sputnik’ Crisis: The War of Minds

October 5, 2007

The American education system is not mobilizing to support science, technology, engineering and math.

Today’s generation of kids is the most technology savvy group that this country has ever produced. They are born with an iPod in one hand and a cell phone in another. They’re text messaging, e-mailing, instant messaging. They’re on MySpace, YouTube & Google. They’ve got Nintendo Wiis, Game Boys, Play Stations.

Their world is… read more

Turing machine built from wood and scrap metal

March 24, 2011


A mechanical machine that can solve the same algorithms as a modern computer has been built out of wood and scrap metal, says software engineer Jim MacArthur.

The machine is a close physical model of the theoretical Turing machine — a device first described by Alan Turing in 1937 as a thought experiment to understand the limits of mechanical computation.

According to the theory, the machine performs… read more
