Increasing stiffness of the aging eye may make older adults more susceptible to eye damage following trauma, according to research at Wake Forest-Virginia Tech School of Biomedical Engineering and Sciences.
"The gradual change in lens stiffness during a persons lifetime leads to a lens that is four times stiffer than at birth, and this has implications for the likelihood of eye injury," said Joel D. Stitzel, Ph.D., of the Virginia Tech-Wake Forest Center for Injury Biomechanics, and three colleagues, writing in the June issue of Archives of Ophthalmology.
Using a computer model of the eye, Stitzel and colleagues investigated possible injury mechanisms in the eyes of elderly individuals and the effects of lens stiffness on injury prediction by the model. The new data document that the risk of certain types of eye injury increases with age.

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.
So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...
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...
