Graphene may lead to exciting new applications in the diagnosis and treatment of neurological diseases, according to a report in the May issue of Neurosurgery, official journal of the Congress of Neurological Surgeons. The paper can also serve as a general introduction to the properties of graphene and its future uses.

Setting a new record, Seagate Technology began shipping its first 400-Gbyte drive, the Barracuda 7200.8, this week.

Implant raises cellular army to attack cancer

January 12, 2009

Implants with an FDA-approved biodegradable polymer that sit in the body and reprogram a person’s immune cells to self-destruct could be used to treat a range of infectious diseases and even cancer.

Computers Get Help from the Human Brain

Columbia University researchers are using a BCI to help search rapidly through images.  (Paul Sajda, Columbia University)

Columbia University researchers are using brain-computer interfaces (BCI) to help computers perform tasks they can’t manage on their own.

Electrical signals within the brain fire before a person even realizes he’s recognized an image as odd or unusual. So in experiments,  the researchers used a BCI to sort through satellite images for surface-to-air missiles faster than any machine or human analyst could manage alone.

Retinal Displays Add Data Layer

April 26, 2001

Computer displays that project images directly onto the viewer’s retina, Terminator-style, are expected to be available this fall.

Microvision Inc., based in Bothell, Wash., plans to market Nomad, a single-color version of that kind of display. A tiny laser projector inside a head-mounted display beams light through the pupil and onto the nerve cells in the retina at 800 x 600 pixels resolution.

Uses include data for surgeons… read more

Novel gel soaks up heavy metal pollution

July 27, 2007

A new foam-like material that could be used to soak up heavy metals in run-off water from polluted industrial sites has been demonstrated by Northwestern University scientists.

Human eggs divide without sperm

December 3, 2004

Researchers have developed a method to make human eggs divide as if they have been fertilized, creating a potential source of embryonic stem cells that sidesteps ethical objections to existing techniques.

The University of Wales researchers made the eggs devide by injecting phospholipase C-zeta (PLC-zeta), an enzyme produced by sperm. The eggs divided for four or five days until they reached 50 to 100 cells — the blastocyst stage.… read more

Microscopic ‘hands’ for building tomorrow’s machines

January 20, 2009
(American Chemical Society)

Chemical and biomolecular engineers in Maryland have developed microscopic, chemically triggered robotic “hands” (“micro-grippers”) that can pick up and move small objects, powered only by certain chemicals that trigger the hands to open or close.

They could be used in laboratory-on-a-chip applications, reconfigurable microfluidic systems, and micromanufacturing.

The grippers are about 0.03 inches wide when open, made from a gold-coated nickel “palm” joined by six pointy… read more

UCSF team develops ‘logic gates’ to program bacteria as computers

December 9, 2010

bacteria logic circuits

A team of UCSF researchers has engineered E. coli bacteria with the key molecular circuitry that will enable genetic engineers to program cells to communicate and perform computations.

The work creates NOR gate logic circuits by “rewiring” communications between the bacteria. The gate controls the release and sensing of a chemical signal, which allows the gates to be connected among bacteria much the way electrical gates would be on… read more

Project JXTA

May 16, 2001

Sun’s new Project JXTA, using P2P networking, could benefit the AI community by combining the processing power of thousands of networked personal computers to create worldwide virtual supercomputers.

Headed by Bill Joy, Project JXTA (juxtapose) encourages “open source” development, with executable and source code for the initial implementation available in Java and C.

Tunneling Electrons Do Math

August 3, 2007

Using a novel computing paradigm involving counting single electrons, Delft University of Technology computer engineers have designed nano-sized circuitry that allows tunneling electrons to perform mathematical division calculations.

Wow! That’s fast TCP!

December 14, 2004

Data has been sent across a wide-area optical network at 101Gbit/sec., the fastest-ever sustained data transmission speed, equivalent to downloading three full DVD movies per second, or transmitting all of the content of the Library of
Congress in 15 minutes.

It was demonstrated by a High Energy Physics research team that included the California Institute of Technology, Stanford Linear Accelerator Center (SLAC) and the Fermi National Accelerator Laboratories (FNAL).… read more

Implant Makes Cells Kill Cancer

January 28, 2009

Harvard University researchers have developed a simple way to achieve immunotherapy inside the body: a polymer implant attracts and trains immune-system cells to go after cancer.

Immunotherapy is a new approach to cancer treatment that could spare patients some of the grueling battery of chemotherapy treatments by retraining the cells of the immune system to recognize and destroy tumors. However, the usual methods for cancer immunotherapy are complex and… read more
