Using math and physics to investigate mad cow disease (bovine spongiform encephalopathy or BSE) and similar diseases caused by infectious proteins called prions is the aim of research by physicists Daniel Cox, Rajiv Singh and colleagues at UC Davis. The researchers are using mathematical models to study issues such as the incubation time, prion "strains" and treatment or detection strategies.
Diseases such as BSE in cattle, Creutzfeld-Jakob disease in humans and chronic wasting disease in deer are all apparently caused by prions, misfolded versions of a normal brain protein. Similar diseases have been found in other animals including cats, mink and rodents, and prion-type proteins have even been found in yeast.
Prions seem to cause disease by triggering normal versions of the same protein to spontaneously fold up the wrong way, creating growing mats and tangles.

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...
Augsburg chemists present a new technology for compressing, storing and transporting highly volatile gases in porous frameworks/New prospects for gas-powered vehicles
Storage of highly volatile gases has always been a major technological challenge, not least for use in the automotive sector, for, for example, methane or...
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...
