Nanotechnology roadmap published: statement by Eric Drexler

December 7, 2007

EXCLUSIVE TO KURZWEILAI.NET — I’m pleased to report that the Technology Roadmap for Productive Nanosystems has finally been released. This marks the completion of the first broad, multidisciplinary effort to explore how current laboratory techniques for atomically precise fabrication can be extended, step by step, toward increasingly advanced products and capabilities.

The Roadmap project was led by the Battelle Memorial Institute, a not-for-profit corporation that manages a set of U.S.

Nanotube Coating Meshes with Living Cells

August 16, 2006

Using a polymer coating that mimics part of a cell’s outer membrane, University of California, Berkeley investigators have developed a versatile method for targeting carbon nanotubes to specific types of cells.

This new coating could spur the development of new anticancer agents that rely on the unique physical characteristics of carbon nanotubes.

Reporting their work in the Journal of the American Chemical Society, the researchers demonstrated that they… read more

More-Precise Genetic Engineering for Plants

April 30, 2009

New techniques allow for more precise changes in plant genes, greatly increasing the efficiency of generating genetically engineered plants for use as food or fuel, or for absorbing carbon and cleaning the environment.

Physicists set new record: register with 14 quantum bits

April 4, 2011

Qbits Register

Physicists at the University of Innsbruck in Austria have achieved controlled entanglement of 14 quantum bits (qubits), realizing the largest quantum register ever produced.

The scientists have almost doubled the record for the number of entangled quantum bits realized experimentally. They confined 14 calcium atoms in an ion trap (similar to a quantum computer), and then manipulated them with laser light. The internal states of… read more

Breathing life into messy sketches

October 14, 2003

AI-based software being developed by the Artificial Intelligence Laboratory at MIT will observes what we draw on the screen and then turns the sketch into computer code.

The smart program is able to interpret what we had in mind from the crude drawing, then animates the sketch by applying the laws of physics to create motion using gravity and momentum — balls roll down slopes, a propeller creates lift.

Glow-in-the-dark cat could help cut disease

December 13, 2007

Scientists have genetically modified three cloned kittens so they appear fluorescent under ultraviolet light, a procedure which could help develop treatments for human genetic diseases.

The Gyeongsang National University (South Korea) scientists cloned the cats after manipulating a gene to change their skin color.

A spokesman for the Ministry of Science and Technology said: “The ability to produce cloned cats with the manipulated genes is significant as it… read more

Scientists Find Memory Molecule

August 28, 2006

Scientists at SUNY Downstate Medical Center have discovered a molecular mechanism that maintains memories in the brain. In an article in Science magazine, they demonstrate that by inhibiting the molecule they can erase long-term memories, much as you might erase a computer disc.

Furthermore, erasing the memory from the brain does not prevent the ability to re-learn the memory, much as a cleaned computer disc may be re-used. This… read more

Rest in Peace, RSS

May 5, 2009

“It’s time to get completely off RSS and switch to Twitter,” advises technology journalist Steve Gillmor.

“Twitter, not RSS, became the early warning system for new content. Facebook, not RSS, became the social Rolodex for events, casual introductions to RSS’ lifeblood, the people behind the feeds. FriendFeed, not RSS, captured the commentsphere. RSS got locked out of its own party….

“The race for realtime is already… read more

Political views are reflected in brain structure

April 8, 2011

Differences in political orientation are tied to differences in the structures of our brains, University College London researchers have found.

Individuals who call themselves liberal tend to have a larger anterior cingulate cortex, while those who call themselves conservative have a larger amygdala, the researchers say. This is consistent with reports showing a greater ability of liberals to cope with conflicting information and a greater… read more

CRN Calls for Global Administration of Molecular Nanotechnology

October 22, 2003

The Center for Responsible Nanotechnology (CRN) is calling for the creation of a collaborative international administrative structure to deal with the problems of molecular manufacturing.

“The threat of MNT is the potential of developing and fabricating dangerous weapons and other undesirables covertly or in large quantity,” said CRN Executive Director Mike Trager.

“This administration will need global scope, and will require careful and innovative planning to balance competing… read more

Move over, silicon: Advances pave way for powerful carbon-based electronics

December 19, 2007

Princeton engineers have developed a novel way to replace silicon with carbon on large surfaces, clearing the way for new generations of faster, more powerful cell phones, computers and other electronics devices.

The Princeton engineers developed a method to place small graphene crystals on a computer chip, demonstrating the method by making high-performance working graphene transistors.

Xerox reveals transient documents

September 8, 2006

Xerox is developing “transient documents” — reusable paper that allows content to be automatically erased after a period of time, ready for fresh printing.

The paper has a photochromic compound that changes from a clear state to a colored state under ultraviolet light and will fade with time.

A projector the size of a sugar cube

September 13, 2006

No larger than a sugar cube, a video projector developed by researchers at the Fraunhofer Institute for Photonic Microsystems contains just a single mirror which can be rotated around two axes.

Google Unveils New Search Products

May 13, 2009

Google released three major search products Tuesday.

Google Search Options lets you drill down with different genres, including elements of time, visualization tools, recently added items, blogs, or images.

Google Squared lets you add or delete results to produce the most useful “square” of information, whichyou can save to your Google account and refer back to later.

Rich Snippets provides more useful information in the blurbs below… read more

Gold ‘nano-bullets’ shoot down tumours

November 5, 2003

Gold “nano-bullets” — tiny silica particles plated with gold and heated with near-infrared light — could seek and destroy inoperable human cancers, researchers report in the Proceedings of the National Academy of Sciences.

“We believe that we should also be able to treat very small metastases, not detected yet,” said Jennifer West, who led the study at Rice University,
