The audacity of nano-hope

February 26, 2009

There has been a flurry of interest in nanobots over the past week, casting quite a wide net that ranges from Nadrian Seeman’s experimental lab work to Ray Kurzweil’s hopeful dreams for the far future, says Foresight Institute president J. Storrs Hall.

Big Blue’s Big Brother Lab

April 24, 2001

The IBM Almaden Research Center in San Jose, California is developing advanced haman-interface computing devices, including:

- A Terminator-style camera with gaze-tracking technology to identify the face and display the name of the person on a sunglasses-mounted display. It could also perform automated language translation of viewed text.

- An electronic communal bulletin board that gives everyone whose personal information is in a database access to their desktop… read more

Parallel universes exist — study

September 25, 2007

Parallel universes really do exist, according to a mathematical discovery by Oxford scientists, described by one expert as “one of the most important developments in the history of science.”

The Oxford team, led by Dr. David Deutsch, showed mathematically that the bush-like branching structure created by the universe splitting into parallel versions of itself can explain the probabilistic nature of quantum outcomes.

Bacteria Enlisted for New Trials on Dental Health

December 1, 2004

The FDA has approved the first clinical trial in which genetically modified bacteria will be put into people’s mouths to test if the bacteria prevent tooth decay.

The new bacteria, which are genetically neutered so they do not make the acid that eats away at teeth, would replace the acid-producing bacteria already present in most mouths.

Researchers discover a potential on-off switch for nanoelectronics

March 4, 2009

Electrical resistance through a single molecular junction can be turned on and off simply by pushing and pulling the junction, a feature that could be used as a switch in nanoscale electronic devices, researchers from Lawrence Berkeley National Laboratory and Columbia University have found.

Scientists to explore nano advancements in DNA sequencing

October 4, 2007

UC Irvine’s Henry Samueli School of Engineering has been awarded $2.18 million to blend traditional DNA sequencing techniques with cutting-edge nanotechnology to develop a faster and less costly method of DNA sequencing and make it a routine part of health care.

FCC considers release of unused TV channels

September 13, 2010

High-tech firms and engineers are dreaming that the Federal Communication Commission’s move to release “white spaces,” or unused television channels, later this month will unleash another boom of mobile innovation.

Calling the communications technology “super WiFi,” FCC Chairman Julius Genachowski said that private carriers are increasingly relying on WiFi hot spots in urban areas to pick up data traffic where their own networks are overburdened. AT&T, for example, has… read more

Nanotube suppliers accused of selling shoddy goods

December 13, 2004

Researchers who buy products such as carbon nanotubes are frequently being sold defective materials, according to a survey of nanotechnology companies.

The survey suggests that the surge in nanotechnology projects has outpaced the ability of companies to reliably supply the basic materials needed by researchers.

PV industry could drive recovery, SEMI says

March 11, 2009

Despite the economic recession, polysilicon shipments have grown constantly in 2008. Demand from the photovoltaics industry more than counterbalanced the chip industry downturn, with shipments up about 7 percent in Q4, 2008 over the third quarter.

And since legal measures have been taken across the globe to bring forward renewable energy sources which will continue to drive the PV industry expansion, this segment is “in an enviable position of… read more

How the brain ‘sees’

May 30, 2001

Neurons in the human visual cortex can detect patterns that are too fine to be consciously perceived, based on research by Sheng He, assistant professor of psychology, University of Minnesota.

Inability to see the too-fine lines is due to a blurring that occurs after the visual cortex receives input.

Cell-squirting needles could ‘weave’ new organs

October 15, 2007

A new approach to “printing” living cells could make it easier to arrange them into precise structures without harming them.

This could enable future therapies where replacement limbs or organs can be printed to order.

Grape Seed May Protect Brain

December 23, 2004

University of Alabama at Birmingham researchers have reported the first direct evidence that a grape-seed extract affects specific proteins in healthy brains in ways that may protect against future age-related dementia.

Grape-seed-extract supplements are thought to have health benefits due to their high content of polyphenolic compounds, which have been shown to have high antioxidant activity

Why compressive sensing will change the world

March 17, 2009

A new Rice University-developed technicque for sampling signals produces 5-megapixel 2D images compressed into 50KB JPEG images using a single pixel — the image is reflected off a randomized array of micromirrors before being focused onto the single pixel.

Uploading Life: Send Your Personality to Space

June 28, 2001

The gradual merging of human beings with their computers over the next century gives rise to the prospect of interstellar immortality, said William Sims Bainbridge at a recent George Washington University Space Policy Institute symposium.

Cognitive neural science, genetic engineering, nanotechnology and information systems may allow the founding of a cosmic civilization, a possibility that does not require flying living human bodies and all the necessities of life to… read more
