The internet is a fantastic source of scientific information these days, but finding the best sites can be just a little tarsome as Georgie Pillson might have said to Lucia. EF Benson fans will know of what I speak. Below are a few that I have found very helpful for different applications. One is even in our own backyard. If you come across a chemistry website that is interesting, please let me know about it and I can add it to the list.

What's new in research: links to articles about relevant developments in science

We talk in class about the limitations on magnification and resolution placed by using visual light. This thinking is based on a very old principle of the wavelength properties of light. In order to see smaller objects we must use shorter wavelengths like electrons. Now it appears there are ways around that and features at the molecular level are now observable. This is a major revolution in scientific capabilities. Check it out at C&ENews
