For most people, the need to wear eyeglasses to read is an inevitable part of aging. The eyes natural lens hardens and loses its ability to change shape, making it more difficult to focus, especially when reading up close.
With age also comes the development of cataracts or clouding of the eyes natural lens. Intraocular lenses (IOLs) traditionally have been used to replace the eyes natural lens after its removal during cataract surgery. However, with the traditional IOLs, most patients still needed to wear glasses for reading and using the computer. This, however, may be changing.
The FDA recently approved the Crystalens, the first of a new generation of IOLs that, in many cases, can allow people to see without eyeglasses or contact lenses. American Academy of Ophthalmology spokesperson Neil F. Martin, M.D., F.A.C.S., of Chevy Chase, Md., "Unlike older fixed-focus IOLs that do not move, the Crystalens is able to move and can focus like a younger eyes natural lens." The Crystalens use hinges, which are attached to the eyes muscles. This allows the lens to move, or accommodate, so you can focus on objects near, far and all distances in-between seamlessly.

Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz (Germany) together with scientists from Dresden, Leipzig, Sofia (Bulgaria) and Madrid (Spain) have now developed and characterized a novel, metal-organic material which displays electrical properties mimicking those of highly crystalline silicon. The material which can easily be fabricated at room temperature could serve as a replacement for expensive conventional inorganic materials used in optoelectronics.
Silicon, a so called semiconductor, is currently widely employed for the development of components such as solar cells, LEDs or computer chips. High purity...

When we put water in a freezer, water molecules crystallize and form ice. This change from one phase of matter to another is called a phase transition. While this transition, and countless others that occur in nature, typically takes place at the same fixed conditions, such as the freezing point, one can ask how it can be influenced in a controlled way.
We are all familiar with such control of the freezing transition, as it is an essential ingredient in the art of making a sorbet or a slushy. To make a cold...
