Ophthalmologists Use Artificial Silicon Retina Microchip To Treat Vision Loss

...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...

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...

New defibrillator signals doctor of patient's irregular heartbeat or device malfunction

...lure. When a patient's status changes, a built-in microchip of Biotronik's Lumos DR-T implantable cardioverter defibrillator (ICD) sends a signal to a satellite via a small transmitter that can be placed on a nightstand, worn on a belt or kept in a purse. In addition, Biotronik's Home Monitoring system vi...

New law for resolution allows unprecedented sharpness in fluorescence microscopy

...ors to the measuring of lithographic structures in microchip manufacturing, and substantial improvements in the quantification of the reaction kinetics of organic molecules (Phys. Rev. Lett., April 15 and Phys. Rev. Lett. May 6). Ever since its invention in the 17th century, the light microscope has served as...

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. Giguère'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 h...

Researchers get neurons and silicon talking

...hnology and the biology." With the help of German microchip company Infineon, NACHIP placed 16,384 transistors and hundreds of capacitors on a chip just 1mm squared in size. The group had to find appropriate materials and refine the topology of the chip to make the connection with neurons possible. Biologica...

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...

In another study, Smith and colleagues showed that these stretch-grown axons could grow when transplanted into a rat mo...

Lost dogs found more often than lost cats, study suggests

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 ...

MU researcher placing eye implants in cats to help humans see

...eterinary ophthalmologist, has been working with a microchip implant to help blind animals "see." According to Narfstrom, the preliminary results are promising. "About one in 3,500 people worldwide is affected with a hereditary disease, retinitis pigmentosa, that causes the death of retinal cells and, event...
