People with a genetic mutation that makes them more resistant to the AIDS virus probably have smallpox to thank, according to two population geneticists at the University of California, Berkeley.
About 10 percent of Europeans have a mutation that disables a protein the Human Immunodeficiency Virus (HIV-1) uses to slip into immune system cells. HIV-1 has a harder time infecting people who have a mutation in one of the two genes that code for this receptor protein, and if these people become infected, their disease progresses more slowly. Those with mutations in both copies of the gene are almost completely resistant to the virus.
This genetic mutation arose as recently as 700 years ago, and some researchers have suggested that the bubonic plague that devastated Europe periodically over the past 1,000 years may have selected for the mutation by sparing those who lacked one or both copies of the gene.

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...
