A decisive step toward a cure for insulin dependent diabetes

... this disease. Using innovative high-density DNA microchip technology, which can test 550,000 genes in a single analysis, Drs. Polychronakos and Hakonarson have detected a new gene involved in type I diabetes. To date, only 4 of the genes responsible for this disease had been identifiedthis now makes 5. We b...

DNA sieve -- Nanoscale pores can be tiny analysis labs

... a time in a space small enough to fit on a single microchip device. The technique involves creating a lipid bilayer membrane similar to those in living cells, and "drilling" a pore in it with a protein (alpha-hemolysin) produced by the Staphyloccoccus aureus bacteria specifically to penetrate cell membranes. ...

...he cancer patient. Future applications that this microchip could be used for are of great importance, as they can provide genetic diagnosis tools for doctors to carry out early diagnoses of diseases associated with our genetic inheritance or with the malfunctioning of the mechanisms for the translation of ou...

Wheat can fatally starve insect predators

...ts, the researchers are beginning work on a single microchip that would be an array of genes from both the Hessian fly and wheat. This will allow the scientists to study insect-plant interactions. Knowing the timing and location of those interactions would enable the scientists to use the promoter tactic only ...

MIT's molecular sieve advances protein research

...l fluids. Millions of pores can be spread across a microchip the size of a thumbnail. The sieve makes it possible to screen proteins by specific size and shape.In contrast, the current technique used for separating proteins, gel electrophoresis, is time-consuming and less predictable. Pore sizes in the gels v...

Microchannels, electricity aid drug discovery, early diagnosis

...Lafayette, Ind. - A tiny fluid-filled channel on a microchip that allows single cells to be treated and analyzed could lead to advances in drug and gene screening and early disease diagnosis. The tool breaks down cell membranes to allow drug and gene delivery and permits examination of intracellular materials ...

Princeton professor foresees computer science revolution

...exponentially because the number of transistors on microchip would double every 18 months or so put computing on the map. But algorithms are going to unleash computing's true potential. I predict that there will be an Einstein of computer scientists. The revolution is yet to come....

Three ORNL technologies earn technology transfer excellence awards

.... Maintaining precise, uniform temperatures during microchip wafer production is important, and this instrument provides an accurate map of the thermal environment throughout the production process. ORNL participants in this effort are Carl Sohns of the Engineering Science and Technology Division and Robert La...

Genetic testing helps physicians zero in on eye disease

...entists have created a first-of-its-kind test on a microchip array that will help physicians hone their diagnoses for patients with the blinding disease known as retinitis pigmentosa (RP). The screening technique has proven to be reliable and cost-effective. In the September issue of Investigative Ophthalmolog...

Scientists discover genetic pathway responsible for breast cancer cell growth

...e human genome project to create a new type of DNA microchip containing the partial DNA sequences of approximately 19,000 genes. Dr. Gigure's team was able to localize where the estrogen receptor was bound in the genome of breast cancer cells, thereby identifying a large number of genes that respond to this ho...

Microchip saves rare turtle from soup-pot

...ped a trip to a Chinese soup-pot, thanks to a tiny microchip implanted in its skin, according to experts from the New York-based Wildlife Conservation Society (WCS), who rediscovered the species four years ago in Cambodia. Wildlife inspectors discovered the 33-pound (15 kg) turtle in a crate of confiscated wi...

New law for resolution allows unprecedented sharpness in fluorescence microscopy

Dye to pinpoint diseases and pathogens

... sample. The chemical screening system fits onto a microchip and soon could test blood and water samples in a matter of seconds. Krull says that while commercial development will still be needed to build a portable technology to facilitate this detection strategy, this research provides the basis for a re-usab...

Ophthalmologists implant five patients with artificial silicon retina microchip

...etinitis pigmentosa (RP). The implant is a silicon microchip 2mm in diameter and one-thousandth of an inch thick, less than the thickness of a human hair. Four patients had surgery Tuesday, January 25. The fifth patient is scheduled for a later date. Rush principal investigator Dr. John Pollack performed the s...

"The flexible and disposable format of the microchip platform will provide an optimum instrumentation for automated high-throughput mass spectrometric analysis of very small sample amounts." Lazar received her Ph.D. in chemistry at Brigham Young University in 1997. Before joining VBI in 2003, she spent...

Robots walk with close-to-human efficiency

...f. When the forward foot hits the ground, a simple microchip controller tells the rear foot to push off. During the forward swing of each leg a small motor stretches a spring, which is finally released to provide the push. The Delft robot uses a pneumatic push at the hip, and the MIT robot uses electric motor...
