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.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
