New, clear-leaded safety glasses allow eye cancer patients to see during week-long sessions of radiation therapy at home, without sacrificing safety, according to a study by Paul T. Finger, MD, director of Ocular Tumor Services at The New York Eye and Ear Infirmary, that was published in the June, 2004 issue of the American Journal of Ophthalmology.
The best treatment today for tumors that grow inside the eye, called intraocular tumors, is plaque therapy, in which a small bowl-shaped radiation device is placed onto the sclera, the white portion of the eye. The radiation destroys the tumor, but also passes through other tissue and some exits the eye. To contain the radiation during treatment, patients, until now, were temporarily blinded because they were required to wear an opaque lead patch.
“The new, clear-leaded eye glasses vastly improve patients’ quality of life during treatment by allowing them to see out of the irradiated eye, and they are just as effective as the patch in blocking radiation from escaping into the environment,” said Dr. Finger. “For patients with only one functional eye, the glasses were remarkable. For the first time, these patients could see and function with the glasses during therapy. Using the lead-patch, they were essentially blind.”

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...
