Environmental change is the selective force that preserves adaptive traits in organisms and is a primary driver of evolution. However, it is less well known that evolutionary change in organisms also trigger fundamental changes in the environment.

Yale University researchers found a prime example of this evolutionary feedback loop in a few lakes in Connecticut, where dams built 300 years ago in Colonial times trapped a fish called the alewife.

In a study published May 23 in the journal Proceedings of the Royal Academy B, the Yale team describes how this event fundamentally changed the structure of the alewife and, with it, the water flea that the alewife feeds upon and the food chain that supports them both. (more…)

For two molecules on blind date, new method predicts potential for attraction or repulsion

Krzysztof Szalewicz, professor of physics and astronomy at the University of Delaware, and Rafal Podeszwa of the University of Silesia Institute of Chemistry in Poland have developed and validated a more accurate method for predicting the interaction energy of large molecules, such as biomolecules used to develop new drugs.

The research is reported as a communication in the April 27 issue of the Journal of Chemical Physics, which is the most highly cited journal in atomic, molecular and chemical physics according to Thomson Reuters. The journal is published by the American Institute of Physics. Despite appearing at the end of April, the paper was on the list of the 20 most-read articles in JCP for that month. (more…)

*Meet the Force-sensitive fans who helped bring the Star Wars universe to life in “Kinect Star Wars,” the ultimate Jedi experience for Padawans of all ages.*

REDMOND, Wash. – Abby Lee walked into a Seattle toy store recently and purchased two LEGO Darth Vader alarm clocks, a Star Wars pop-up book, and a few LEGO speeder bikes. The bemused checkout clerk asked if she was going to a birthday party.

“No,” Lee replied. “I’m going to work.” (more…)
