Library of Congress Plans World Digital Library

November 22, 2005

The U.S. Library of Congress is kicking off a campaign on Tuesday to work with other nation’s libraries to build a World Digital Library, starting with a $3 million donation from Google Inc.

Over the past decade, the American Memory Project of the Library of Congress has digitized more than ten million items to create a documentary record of Americana.

These include manuscripts, maps, audiovisual recordings,… read more

Light Particles Are Duplicated More Than a Mile Away Along Fiber

January 30, 2003

Scientists have taken particles of light, destroyed them and then resurrected copies more than a mile away. Previous experiments in “quantum teleportation” moved particles of light about a yard.

Possible uses include sending unbreakable encrypted messages and as fiber-optics repeaters.

First Results From The Allen Telescope Array

August 13, 2009

The Allen Telescope Array, a joint operation between the SETI Institute in Mountain View and the University of California, Berkeley, has imaged the movement of atomic hydrogen clouds in the intergalactic space between nearby galaxies, which could help solve one of the big mysteries of star formation.

Turning Glare Into Watts

(Isaac Brekke/The New York Times)

As prices rise for fossil fuels and worries grow about their contribution to global warming, solar thermal plants are being viewed as a renewable power source with huge potential.

The technology involves covering acres of desert with mirrors that focus intense sunlight on a fluid, heating it enough to make steam. The steam turns a turbine and generates electricity. Some experts say that solar thermal plants could… read more

Why this brain flies on rat cunning

December 7, 2005

A “brain” grown from 25,000 neural cells extracted from a single rat embryo has been taught to fly an F-22 jet simulator by scientists at the University of Florida.

They hope their research into neural computation will help develop sophisticated hybrid computers with a thinking biological component. The first result could be to enable scientists to enabling more flexible and varied means of solving problems.

Intel unveils ‘building blocks’ for 10-GHz processors

February 11, 2003

Intel Corp. plans to disclose this week several technologies that will make good on its promise to deliver 10-GHz or faster microprocessors by the end of this decade. The company is also expected to develop and ship processors that run at speeds from 10 to 20 GHz by then.

Video appears in paper magazines

August 21, 2009

The first video-in-print ads, using chips and thin screens around the size of mobile phone displays, will appear in select copies of Entertainment Weekly magazine in September and hold 40 minutes of video.

The first clips will be promos for CBS programs and Pepsi.

Borrowing from microfabrication techniques used in the semiconductor industry, MIT and Harvard Medical School (HMS) engineers have developed a simple, inexpensive way to create three-dimensional brain tissues in a lab dish, using brain cells taken from the primary cortex of rats.

The new technique yields tissue constructs that closely mimic the cellular composition of those in the living brain, allowing scientists to study how neurons… read more

Stems cells as drug delivery carriers to the brain

December 15, 2005

Engineered human brain progenitor cells, transplanted into the brains of rats and monkeys, can effectively integrate into the brain and deliver medicine where it is needed, bypassing the blood-brain barrier, University of Wisconsin-Madison researchers have found.

The Wisconsin team obtained and grew large numbers of progenitor cells from human fetal brain tissue. They then engineered the cells to produce a growth factor known as glial cell line-derived neurotrophic factor… read more

Tiny ruler to measure macromolecular movement

June 17, 2011

Paul Alivisatos of the Lawrence Berkeley National Laboratory and colleagues have designed a first-of-its-kind ruler capable of measuring the configuration and movement of macromolecules, such as DNA.

The researchers constructed an “H”-shaped device out of five gold nanorods, the length and position of each of which could be controlled. They then looked for changes in spectra associated with plasmon coupling — the tendency… read more

Swarm Intelligence: An Interview with Eric Bonabeau

February 26, 2003

Dr. Eric Bonabeau takes us from his childhood nightmares of carnivorous wasps to applying the theories of swarm intelligence to solving real problems in the business world.

“It’s no longer possible to use traditional, centralized, hierarchical command and control techniques to deal with systems that have thousands or even millions of dynamically changing, communicating, heterogeneous entities,” he says. “I think that the type of solution swarm intelligence offers is… read more

Where Have You Gone, Bell Labs?

August 31, 2009

The root of the current lack of new, high-quality job creation is the massive scaling back of science and engineering research, which has in the past made enormous contributions to science, technology, and the economy, including the creation of millions of high-paying jobs, says management consultant Adrian Slywotzky.

Here’s what’s needed to get that model back on track, he suggests:

• Clear national goals in two or three… read more

An Assistant Who May Need the Occasional Battery

March 17, 2008

Georgia Tech researchers have built “El-E,” a laser-pointer guided robot that can fetch objects as varied as towels, wallets, or coffee mugs with no need for elaborate computer modeling.

The laser pointer gives the robot just enough context and guidance to solve the problem of figuring out which object in a room to pick up.

This type of dexterous robot may be helpful in assisting people with severely… read more
