Bookmarked Information Theory and Evolution by John S. Avery (World Scientific)
This highly interdisciplinary book discusses the phenomenon of life, including its origin and evolution (and also human cultural evolution), against the background of thermodynamics, statistical mechanics, and information theory. Among the central themes is the seeming contradiction between the second law of thermodynamics and the high degree of order and complexity produced by living systems. This paradox has its resolution in the information content of the Gibbs free energy that enters the biosphere from outside sources, as the author shows. The role of information in human cultural evolution is another focus of the book. One of the final chapters discusses the merging of information technology and biotechnology into a new discipline — bio-information technology.

Another Reason to Shun Chick Flicks: Crying = Less Sex!?

A new study by Noam Sobel, of the Olfaction Research Group at the Weizmann Institute of Science in Rehovot, Israel, and others are reporting in the journal Science this week that men in their study who sniffed the tears of crying women produced less testosterone and found female faces less arousing.

Previous studies in animals such as mice and mole rats have shown that tears convey important chemical messages which are used to attract or repel others of the same species.  There is good evidence for an interesting type means of higher-level chemical communication. These previous studies also incidentally show that “emotional” tears are chemically distinct from “eye-protecting” types of tears.

Scientific American’s “60 Second Science” (via link or listen below) podcast has a good audio overview of the study for those without the time to read the paper.

In press reports, Adam Anderson, a University of Toronto psychologist who was not involved with the study, posited that the results may imply that “tears have some influence on sexual selection, and that’s not something we associate with sadness.” He continued, “It could be a way of warding off unwanted advances.”

This study provides a new hypothesis for the evolution of crying in humans. (Now if only we could find some better reasons for laughter…)

The take home message may be that guys should not take their dates out to weepy chick flicks, or alternately women reluctantly accepting “pity dates” should force their suitors to exactly these types of testosterone damping films.

Matt Ridley’s Thesis: When Ideas Have Sex

Watched When ideas have sex by Matt Ridley from ted.com
At TEDGlobal 2010, author Matt Ridley shows how, throughout history, the engine of human progress has been the meeting and mating of ideas to make new ideas. It's not important how clever individuals are, he says; what really matters is how smart the collective brain is.
When extrapolated a bit, this thesis is one of the best arguments for why Twitter and other methods of social media are so useful.  There really is a great idea at the core of this presentation.

A lovely bit of satire on Evolution vs. Creationism… what will they come up with next?
