Interesting Articles: December 2007

* Escaping flatland (Science News). An article about how cells grown in a flat medium such as a petri dish behave differently than in a real, three-dimensional setting. At the core of the result is the idea that sometimes one must question the most basic simplifying assumptions in experimental science.
* Airy theory, but true (Science News). Frankly, I find this physical phenomenon unbelievable and incomprehensible. I found a longer article on the topic, Scientists make first observation of Airy optical beams (PhysOrg.com), but it makes the effect no more understandable to me.
