In experiments with fruit flies, Johns Hopkins researchers have found that blindness induced by constant light results directly from the loss of a key light-detecting protein, rather than from the overall death of cells in the retina, which in humans is a light-sensitive tissue at the back of the eye.
The research, reported in the Dec. 14 issue of Current Biology, overturns the long-standing belief that blindness from chronic light exposure is a direct result of overall retinal degeneration and cell death.
Although many animals, and presumably humans, lose both their retinal cells and vision after exposure to low levels of light for long periods, the relationship between exposure and blindness had been poorly understood.

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.
