With the evolution of technology, things that could be only imagined have been changing into reality. In past one could have only dreamed about their sunglasses turning darker or lighter with the touch of a button. But now, a range of colours and shading is possible with prototype eyewear made of electrochromic materials. Sunlight can vary significantly during outdoor activities such as motorcycling or skiing. Customary sunglass lenses, created with tinted glass or polycarbonate materials, have a fixed colour state. Lenses made with photochromic materials adjust to changing light, but rather slowly. Chemical engineer Chunye Xu and colleagues at the University of Washington have been working on "smart" sunglasses that can lighten or darken on command. The electrochromic polymer in Xu's prototype enables the lenses to lighten or darken in literally one second with just several milli watts of power. The button that engages the battery is located on the sidearm of the eyewear.

When it comes to scientific study in nanoscience, our eyes fail us. The fact is we're all blind at the nanoscale, the smallest object we can see still looms thousands of times larger than a typical nano-sized structure. Even the most powerful microscopes can't peer into the nanoscale directly. So the blind have the ability to understand what's going on at the nanoscale just as much as anyone else. To give blind students a feel literally for nanoscience and technology, Greenberg and Mohammed Farhoud, a senior biochemistry student working with UW-Madison Center for Biology Education (CBE) Director Dave Evans, are building three-dimensional models of nano-surfaces that are large enough to be explored with the hands. Their first attempt replicates "NanoBucky," a nanoscale version of the UW-Madison mascot, Bucky Badger, made entirely from tiny carbon nanofiber hairs. Greenberg and Farhoud are confident they can build models from data produced by other common tools of the nanotechnology trade, such as atomic force microscopy (AFM). They also plan to duplicate other nanoscale surfaces, such as those made from materials called block copolymers.

As there is a huge shortage of donor organs, researchers have been trying to find ways to transplant animal organs across different species with the eventual aim of transplanting animal organs into humans. Xenotransplantation is the transplantation of living cells, tissues or organs from one species to another such as from pigs to humans. The major drawback according to Dr Muhammad Mohiuddin (US National Heart, Lung, and Blood Institute) is that the immune system in the animal receiving the organ tends to reject the transplant. In addition to immune rejection, another concern about xenotransplantation is the risk of transmitting viruses and other pathogens from one species to another. However, the recent developments of genetically modified pigs are more compatible with humans. There are some promising facts which suggest xenotransplantation may eventually benefit humans. For example, insulin-producing cells from pigs were transplanted into monkeys with diabetes and this led to complete reversal of diabetes for over 100 days. Xenotransplantation offers a potential treatment for end-stage organ failure, one of the most important health problems facing the industrialized world today.
