Earth’s magnetic field ‘boosts gravity’

September 23, 2002

Hidden extra dimensions are causing measurements of the strength of gravity at different locations on Earth to be affected by the planet’s magnetic field, French researchers say.

DNA 2.0: A new operating system for life is created

February 15, 2010

University of Cambridge scientists have created a new way of using the genetic code, allowing proteins to be made with properties that have never been seen in the natural world.

The breakthrough could eventually lead to the creation of new or “improved” life forms incorporating these new materials into their tissue. For example, they could help make drugs that can be taken orally without being destroyed by the acids… read more

Using a light touch to measure protein bonds

July 1, 2008

MIT researchers have used optical tweezers (light beams) to achieve a precise measurement of the strength of bonds between two protein molecules important in cell machinery.

They focused on proteins that bind to actin filaments, an important component of the cytoskeleton that provide structural support, help the cell crawl across a surface or sustain a load (in muscle cells).

They found the force holding the proteins together is… read more

Diamond-based quantum cryptography and quantum computation

March 18, 2011

A team of physicists led by J.P. Hadden at the University of Bristol.has developed atomic-scale light sources of single photons, which could open the door to diamond-defect-center-based quantum cryptography and quantum computation.

Fluorescent “defect centers” in diamond are trapped in a transparent material that’s large enough to be picked up manually. Unlike quantum dots or trapped atoms, they don’t need to be… read more

Accelerating Change 2005 focuses on AI and IA

August 31, 2005

This year’s Accelerating Change 2005 conference (AC2005), Sept. 16-18 at Stanford, promises to be “outstanding,” organizer John Smart tells Accelerating Intelligence news, with 51 top speakers and emcees.

The conference focuses on “artificial intelligence and intelligence amplification transforming technology, empowering humanity.” Consistent with that theme, Ray Kurzweil will keynote the event and will distribute pre-publication signed copies of his The Singularity is Near to the first 250… read more

University of Southampton neuroscientists have developed a method called “multicolor RGB tracking” to improve our understanding of how the brain works by color-marking individual brain cells in mice allows them to be tracked over space and time.*

To mark a brain cell, they inject a solution that contains three viral vectors (delivery of genes by a virus) to create a fluorescent protein in each cell. Each cell… read more

Inventors forecast 21st century innovations at Patent & Trademarks Office bicentennial

October 16, 2002

Oct. 16 – What do inventors expect to see in the 21st century? That was the key question today in a round table discussion with National Inventors Hall of Fame inductees and Richard Russell, Associate Director of Technology at the White House Office of Science and Technology Policy, at the U.S. Department of Commerce in Washington DC.

The inductees, some of the world’s greatest living inventors, gathered… read more

Life-like evolution in a test tube

February 22, 2010

Scripps Research Institute scientists have synthesized RNA enzymes (also known as ribozymes) that can replicate themselves chemically without the help of any proteins or other cellular components.

Many scientists believe that early life was based on RNA and predated the arrival of life based on DNA and proteins.

Open-source Firefox OS for smartphones due out in 2013

September 11, 2012

Mozilla posted a new video on YouTube that offers a fresh, up-to-date look at its forthcoming mobile operating system in action, PC World reports.

Recorded last Thursday, the video — embedded below — demonstrates the latest build of Firefox OS running on a developer phone by Chinese manufacturer ZTE.

Built using HTML5, the operating system is intended for use on smartphones built entirely to… read more

Gold, DNA Combination May Lead To Nano-Sensor

July 9, 2008

Duke University scientists have developed intracellular biological sensors based on gold nanostructures with tethered DNA recognition molecules that can create signals from subtle changes in light reflecting off their nanoscale surfaces.

By measuring color changes, researchers can tell what is happening at the molecular level, and the nanoparticles are small enough to pass through cell membranes.

Robo-justice

September 13, 2005

There is growing interest–even in an American legal establishment usually resistant to change–in finding ways to incorporate artificial intelligence into the law.

Nanotech-based visualization

November 4, 2002

Nanotechnology-based visualization technologies will allow people to be someone else in virtual reality in the future, Ray Kurzweil said in his Capstone address on “Visualization and Human-Machine Interaction in the 21st Century” at IEEE Visualization 2002 in Boston on November 1.

Kurzweil presented a scenario involving a direct connection between the human brain and nanobot-based implants for communicating between the analog world of neurons and… read more

Touch Screens that Touch Back

March 3, 2010

A new haptic interface that creates the sensation of a physical button when a user touches the screen has been designed by California-based company Immersion.

The device uses piezoelectric actuators that generate rapid horizontal vibrations to create the sensory experience.

Schwarzenegger tours NASA/Ames to tout agency’s fire-fighting technology

July 15, 2008

NASA/Ames Research Center researchers are taking data from a remotely controlled airplane and delivering real-time infrared images of hot spots and flare-ups to fire commanders on the ground.

The $6 million Ikhana aircraft has an onboard sensor that can look through the smoke and detect temperatures ranging from one-half degree to 1,000 degrees Fahrenheit. Ikhana sends images through a communications satellite to NASA/Ames, where the imagery is superimposed over… read more

The digital Dark Age

September 26, 2005

A major challenge faces the “digital” generation: how can masses of machine-generated, machine-read material be stored in a form that is safe, secure from degradation.

Computer experts worldwide believe that, far from a panacea that provides increasingly efficient answers to problems of recording, storing and retrieving information, technology is deeply flawed.

They fear that rather than ushering mankind into a techno-utopia of paperless offices and clean, eco-friendly, endlessly… read more
