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.

Scientists from the Theory Department of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science (CFEL) in Hamburg have shown through theoretical calculations and computer simulations that the force between electrons and lattice distortions in an atomically thin two-dimensional superconductor can be controlled with virtual photons. This could aid the development of new superconductors for energy-saving devices and many other technical applications.
The vacuum is not empty. It may sound like magic to laypeople but it has occupied physicists since the birth of quantum mechanics.
