Reactivating 'Week in Science'
The website Week in Science has resumed operations. Two new articles have appeared entitled Fill the Tank with Water Please and Bacterial Geometric Trails. Fill the Tank with Water tells of a potential promising new technology that could have us someday filling our lawnmowers and automobiles with water instead of gasoline. The fuel burned would be hydrogen and the exhaust water vapor. Very environmental friendly.
Bacterial Geometric Trails refers to a PNAS paper which notes some interesting movement patterns of a bacterial pathogen. The different patterns are mathematically defined and explained in terms of the operation of an underlying mechanism.
