Discovery offers hope for a pharmaceutical intervention to treat some forms of retinitis pigmentosa
Gene mutations that impair the ability of photoreceptor cells to properly dispose of waste - and as a result cause the blinding eye disease retinitis pigmentosa - have been identified by vision researchers at the University of Utahs Moran Eye Center. The discovery raises concerns that carbonic anhydrase inhibitors (medications often used to treat both heart and eye diseases) may adversely affect vision. The study is published in the November 24, 2004 online version of the journal Human Molecular Genetics.
Retinitis pigmentosa (RP) is one of the most common causes of blindness. It affects one in 3,500 people or approximately two million people worldwide. Patients with RP typically are diagnosed with night blindness and, as the disease progresses, they eventually lose all of their peripheral vision and a significant portion of their central vision.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
