Powerful Batteries That Assemble Themselves

September 29, 2006

Biology may be the key to producing light-weight, inexpensive, and high-performance batteries that could transform military uniforms into power sources and, eventually, improve electric and hybrid vehicles.

Through a combination of genetic design and directed evolution, Angela Belcher, an MIT professor of biological engineering and materials science, and colleagues have created viruses that coat themselves with inorganic materials they wouldn’t touch in nature, forming crystalline materials, which are doped… read more

Stanford expands free online IT course offerings

November 30, 2011

Stanford University plans to offer eight more free online computer science classes beginning in January, ZDNET Service Oriented reports.

The new courses are Software as a Service, Computer Science 101, Machine Learning, Cryptography, Natural Language Processing, Human Computer Interaction, Design and Analysis of Algorithms I, and Probabilistic Graphic Models. The previous courses on Introduction to Artificial Intelligence, Introduction to Databases and Introduction to Machine Learning started in… read more

Memories in the Corner of My Eye

November 12, 2003

Glasses with a tiny television screen embedded into one of the lenses and hooked up to a PDA are being used to project 1/180-of-a-second subliminal reminders to wearers.

Google’s ‘Social’ Gmail: Could It Really Work?

February 9, 2010

Google’s social networking component for Gmail will reportedly aggregate updates from friends into single tweet-like status updates.

Physicists Produce Quantum-Entangled Images

June 26, 2008
(NIST)

Researchers from the National Institute of Standards and Technology (NIST) and the University of Maryland (UM) have produced “quantum images,” pairs of information-rich visual patterns whose features are entangled (linked by the laws of quantum physics).

Matching up both quantum images and subtracting their fluctuations, their noise is lower (so their information content potentially higher) than it is from any two classical images.

In addition to… read more

Engineering Food at Level of Molecules

October 11, 2006

Food companies remain wary of pushing nanotechnology too far and too fast for safety-conscious consumers. But they are tantalized by nanotechnology’s capacity to create valuable and sometimes novel forms of everyday substances,like food ingredients and packaging materials.

OilFresh, based in Sunnyvale, Calif., is marketing a novel device to keep frying oil fresh. OilFresh grinds zeolite, a mineral, into tiny beads averaging 20 nanometers across and coats them with an… read more

DARPA seeks smartphone app developer for ADAPT program

December 8, 2011

ADAPT

DARPA is looking to tap the smartphone application development community with experience in creating “adaptive applications.”

Current sensor systems, like those being developed for DARPA’s Adaptable Sensor System (ADAPT) program, are increasingly complex; they offer advances in capabilities far beyond their current use. Unmanned Aerial Vehicles (UAVs), for example, have become indispensible intelligence, surveillance and reconnaissance (ISR) platforms on today’s battlefield.

Free stem cells for all?

October 16, 2006

Free stem cells for all? Possibly, now that the US Patent and Trademark Office is re-examining key patents on human embryonic stem cells that some say have been stifling stem cell research.

Multi-purpose photonic chip paves the way to programmable quantum processors

December 13, 2011

University of Bristol researchers have demonstrated quantum entanglement on a silicon chip, allowing for eventual development of a practical quantum computer.

The chip performs several experiments ordinarily carried out on a large optical bench. The chip consists of a network of tiny photonic waveguides (channels) that guide, manipulate and interact single photons. Using eight reconfigurable electrodes embedded in the circuit, photon pairs can be manipulated… read more

Ultranet will link scientists and supercomputers at 40 Gbps

November 26, 2003

The Oak Ridge National Laboratory will design a high-speed network called Science Ultranet that operates at up to 40 gigabits per second, ORNL has announced.

With $4.5 million funding from the Department of Energy, Science UltraNet will allow for distributed collaborative visualization, remote instrument control, and remote computational steering, which allows scientists to control and guide computations being run on supercomputers from their offices. These tasks require high-speed transfer… read more

Rewinding the Clock for Aging Cells

February 18, 2010

Researchers from Children’s Hospital Boston found that reprogramming skin cells from patients with a premature aging disease (dyskeratosis congenita) to an embryonic state lengthened the telomeres* in the cells.

The researchers found that the induced pluripotent cell reprogramming appeared to activate a specific component of the telomerase enzyme, a discovery that they hope to use to develop new treatments for this and other telomerase-related diseases.

Chip-cooling Technology Achieves ‘Dramatic’ 1,000-watt Capacity

July 7, 2008

Purdue University researchers have developed a technology that uses “microjets” to deposit liquid into tiny channels and remove five times more heat (1,000 watts per square centimeter) than other experimental high-performance chip-cooling methods for computers and electronics.

Chiang Mai University involved in tiny nanobot’s human voyage

October 24, 2006

A Chiang Mai University team has developed a motor that will power a microscopic robot on an expedition through human blood vessels, looking for such things as tiny tumors in internal organs.

The piezoceramic device is remote controlled by low-voltage electric current or microwaves, and is propelled by changing its size.

Ironing Out Blood Impurities

December 9, 2003

Magnetized nanoparticles may one day be the treatment of choice for people needing to detox.

The 100 to 5,000 nanometers nanoparticles, designed at the Argonne National Laboratory, have receptors designed to identify, and then latch onto, target molecules. The nanoparticles are injected into the bloodstream, where they circulate through the body, picking up their target toxins as they go.

A magnet housed in a handheld unit and a… read more

Rising Threat of Infections Unfazed by Antibiotics

March 1, 2010

Gram-negative bacteria are killing tens of thousands of hospital patients each year, spreading worldwide, and evolving to become ever more immune to existing antibiotics, with some strains resistant to virtually every antibiotic.
