Physics - Arrow of Time Emerges in a Gravitational System
"Standard approaches to the arrow of time typically require a rare statistical fluctuation, or, often, the smuggling in of assumptions about initial conditions. Their work offers evidence that ordinary gravitational dynamics may itself be enough to produce the simple “initial” point that can give time a direction."

Stephen Meyer's Bogus Information Theory
Criticism of Stephen Meyer's "The Signature in the Cell" based on Meyer's mistakes in information theory (or rather, the way he uses a made up definition of "information"). HT to Leonard Richardson, who rightly says it's a good introduction to what "information" does mean, regardless of what you think of Meyer's book.
