Ophthalmology researchers at Washington University School of Medicine in St. Louis have identified a key risk factor for the development of cataracts. For the first time, they have demonstrated an association between loss of gel in the eyes vitreous body -- the gel that lies between the back of the lens and the retina -- and the formation of nuclear cataracts, the most common type of age-related cataracts.
The researchers reported their findings in the January issue of Investigative Ophthalmology and Visual Science.
"Most people think of cataracts as a problem that we develop if were lucky to live long enough, but clearly there are people who live to quite an old age and never get cataracts," says principal investigator David C. Beebe, Ph.D., the Janet and Bernard Becker Professor of Ophthalmology and Visual Sciences and professor of cell biology and physiology. "The perception that they are inevitable may have skewed our perspective about preventing cataracts, but it may be possible to prevent them if we can continue to home in on the causes of cataracts."

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
