IBM, Mayo Clinic team up to improve medical imaging: studying use of the PlayStation 3 Cell chip

January 14, 2008

An IBM-Mayo Clinic team is using the PlayStation 3 Cell chip to significantly speed up processing in medical imaging systems.

Signal Jammer

June 18, 2003

An academic experiment has lead to a new class of drug for attacking heart disease.

Researchers found that oxidants are involved in activating the genes that initiate the inflammatory process that causes atherosclerosis and that a modified form of an antioxidant, Probucol (an anticholesterol medication) blocks this process.

Inside the Military’s Secret Terror-Tagging Tech

June 4, 2009

The military has spent hundreds of millions of dollars researching, developing, and purchasing “Tagging tracking and locating” (TTL) devices, including laser-based reflectors, RFID tags capable of responding from twelve miles away, homing beacons so tiny, they can be woven into fabric or paper, and invisible chemical dye to mark terrorists.

Microsoft creates academic search site to rival Google’s

April 12, 2006

Windows Live Academic Search, launched in beta Tuesday night, lets researchers search the contents of academic journals to find abstracts and, if they subscribe to the journals, get the documents from the publishers’ sites.

The service, which for now focuses on computer science, electrical engineering and physics, includes tools for researchers, such as the ability to quickly extract information for citations.

Cloning Said to Yield Human Embryos

January 18, 2008

Scientists at Stemagen, a small biotechnology company, say they have used cloning to create human embryos from the skin cells of two men.

Although the embryos grew only to a very early stage, the work could also theoretically be seen as a step toward creating babies that are genetic copies of other people. The work also represents a step toward the promise of creating personalized embryonic stem cells that… read more

Microchip Promises Smart Artificial Arms

July 1, 2003

British scientists are developing a microchip that gives people with prosthetic arms greater control over these limbs. The chip works by turning thought processes in the brain into direct advanced physical movements.

Sorting out semiconducting and conducting nanotubes

November 21, 2011

Polimer coated nanotubes

A technique to selectively sort semiconducting single-walled carbon nanotubes and conducting nanotubes has been discovered by researchers at Stanford University, University of California-Davis, and the Samsung Advanced Institute of Technology.

When nanotubes are manufactured, semiconducting nanotubes, which work for transistors and solar cells, are mixed with conducting nanotubes, which work for batteries. Mixtures of conducting and semiconducting nanotubes do not carry enough current for wires or battery… read more

Acoustic Black Hole Created in Bose-Einstein Condensate

June 11, 2009

The sonic equivalent of a black hole in a Bose-Einstein Condensate has been created by Israel Institute of Technology researchers using a deep potential well to generate an event horizon between subsonic and supersonic flow of atoms.

Sonic black holes ought to produce Hawking radiation, since quantum mechanics predicts that pairs of “virtual” phonons with equal and opposite momentum ought to be constantly springing in and out of existence… read more

Gamers may soon control action with thoughts

April 26, 2006

Two start-ups have developed technology that monitors a player’s brain waves and uses the signals to control the action in games. They hope it will enable game creators to immerse players in imaginary worlds that they can control with their thoughts instead of their hands.

The world’s lowest noise laser

January 27, 2008

Max Planck Institute researchers have set a new record for photon noise control in a laser beam, creating a laser that has the precision to be used as a gravitational wave detector.

Gladiator-style ‘wars’ select out weak programs

July 14, 2003

Computer scientists have found the ultimate way to debug their programs –let them compete against other programs in a gladiator-style tournament.

Dubbed Grid Wars II, the contest held at the ClusterWorld conference in San Jose, California, last month was like a software version of television’s Robot Wars and Battle Bots. In each battle, programs fought to gain control of processing power in a huge parallel computer.

Tiny magnets could clear diseases from the blood

November 28, 2011

Carbon-encapsulated nanomagnet

University of Zurich researchers are developing magnetized nanoparticles with antibodies that could someday strip potentially harmful substances from the blood, treating people suffering from drug intoxication, bloodstream infections, and certain cancers.

Synthetic cells get together to make electronics

June 18, 2009
(Nature)

A network of artificial cells that work together to act as a rectifier (AC to DC converter) has been built by researchers at the University of Oxford and the University of Massachusetts at Amherst.

Like real cells, the protocells are droplets of watery fluid enclosed in an oily membrane, but they can fuse together, forming unidirectional electronic circuits.

The droplet networks could be used as an… read more

IBM announces data storage breakthrough

May 16, 2006

Researchers at IBM say a new
method for cramming 6.67 billion bits into a square inch of tape and 8 terabytes on a single cartridge.

They contend that would be 15 to 20 times denser than today’s industry-standard tape products.

Cheap Hydrogen

January 31, 2008

Nanoptek, a startup based in Maynard, MA, has developed a new way to make hydrogen from water using solar energy.

The company says that its process is cheap enough to compete with the cheapest approaches used now, which strip hydrogen from natural gas, and it has the further advantage of releasing no carbon dioxide.
