Being Invisible

July 9, 2003

Next-gen optical camouflage is busting out of defense labs and into the street.

US Defense Department press releases citing “adaptive,” “advanced,” and “active” camouflage suggest that the government is working on devices like this.

But to achieve true invisibility, optical camouflage must capture the background from all angles and display it from all perspectives simultaneously. This requires a minimum of six stereoscopic camera pairs, allowing the computer to… read more

Light pipes track motion

July 8, 2003

Researchers at Duke University have devised a simple tracking method that promises to dramatically reduce the computing resources needed for computer vision systems that allow computers and robots to sense their surroundings.

The researchers’ method dispenses with the complicated software and lenses and instead maps the angles of light radiating from a source by channeling the light through set of pipes onto a set of light detectors. As an… read more

DNA makes nano barcode

July 8, 2003

Duke University researchers have programmed strands of synthetic DNA to self-assemble into a bar-code-like structure. The process could eventually be used to make templates that will enable molecule-by-molecule construction of electronic circuits.

The method coaxes columns of looped and non-looped strands of DNA to stack into a pattern that is readable by microscope. The researchers programmed the process to produce two different barcodes — 01101 and 10010. The prototype… read more

Nanotechnology Group to Address Safety Concerns

July 7, 2003

The NanoBusiness Alliance plans to announce a new task force today to address health and environmental concerns about the health impact of inhaling or ingesting nanoscale particles.

Microbe fuel cell packs more power

July 7, 2003

German researchers have created a prototype microbial fuel cell that generates ten times more energy from bacteria. It works by capturing energy produced by Escherichia coli as it feeds on sugar.

Brain rewiring during learning boosted by drug

July 7, 2003

The the sense of touch can be significantly enhanced by cortical remapping using stimulant drugs, researchers at Ruhr-University Bochum in Germany have found.

The findings could help to restore touch sensation in the elderly or injured and lead to treatments for some forms of chronic pain associated with distortions of the brain’s body map.

The Lure of Data: Is It Addictive?

July 7, 2003

Multitasking may be counterproductive and addicting, say Harvard researchers, naming it “pseudo-attention deficit disorder.”

Multitaskers have shorter attention spans, become frustrated with long-term projects, thrive on the stress of constant fixes of information, and physically crave the bursts of stimulation from checking e-mail or voice mail or answering the phone. The process takes the same pathway as drugs of abuse and pleasure, generating dopamine, the researchers believe.

Virus as Metaphor: Microbiology and ’28 Days Later’

July 7, 2003

The terrifying new movie, “28 Days Later,” shows that microbial plagues have displaced nuclear winter in the public’s mind as the way the world will end.

However, the “Rage” virus, which produces dramatic effects within 20 seconds, transforming its victims into enraged, wild-eyed, indiscriminate killers and quickly spreading worldwide, is unrealistic.

Website turns tables on government officials

July 6, 2003

MIT researchers have created the Government Information Awareness (GIA) project as a response to the US government’s Total Information Awareness program.

Internet users can submit their own intelligence reports on government officials; they will be published with no effort to verify their accuracy. Software similar to Google also gleans information from Internet sites that store information about politicians. Users can also access information compiled from various real-time… read more

Quantum ‘Super Molecule’ Created

July 3, 2003

Scientists at NIST have taken an important step toward creating a “super molecule,” a blend of thousands of molecules acting in unison that would provide physicists with an excellent tool for studying molecular quantum mechanics and superconductivity.

The experiment, conducted at 150 nanoKelvin above absolute zero, may lead to creation of fermion superfluids made from gases that would be much easier to study than solid superconductors.

The researchers… read more

‘Google Pocket Guide’ released

July 3, 2003

O’Reilly has released the “Google Pocket Guide” to help Google users learn the fundamentals of a Google search.

The book includes making the most of Google’s special syntaxes, hidden options, and powerful combinations; consulting the Google dictionary; looking up individuals and businesses in the Google phonebook; finding related web sites and pages; and restricting or expanding a Google search by subject, web site, domain, time, title, etc.

For an Ailing Retina, Instant Diagnosis From Afar

July 3, 2003

Telemedicine researchers are sending digitized photographs of people’s eyes to ophthalmologists via high-speed Internet for remote examinations.

The cameras can be used to identify eye diseases including diabetic retinopathy, macular degeneration, glaucoma, and retinopathy of prematurity.

The recent introduction of six-megapixel cameras for $1,500 and 10-megapixel cameras for $5,000 to $8,000, and a sharp drop in the prices of high-definition monitors have aided the cause.

Government, industry warn of mass hacker attacks on July 6

July 3, 2003

The government and private technology experts warned Wednesday that hackers plan to attack thousands of Web sites Sunday in a loosely coordinated “contest” that could disrupt Internet traffic.

Patent for ‘ethical AI’ issued

July 2, 2003

A U.S. patent for “ethical artificial intelligence” was issued today. The “Inductive Inference Affective Language Analyzer Simulating Artificial Intelligence” patent (No. 6,587,846) was issued to inventor/author John E. LaMuth.

“It enables a computer to reason and speak in an ethical fashion, serving in roles specifying sound human judgement, such as public relations or security functions,” LaMuth said. “This innovation is completely novel in its ability to simulate… read more

Scientists to Map Known Universe

July 2, 2003

Arecibo Observatory is receiving six more radio receivers to expand its range.

Once the “ALFA Project” is completed next year, the observatory’s staff of 15 scientists will create a detailed map of new pulsars, supernova, black holes and planets.
