New theory explaining the prevalence of homosexuality focuses on epigenetics

Posted 15 Jul 2013 / 0

The Quarterly Review of Biology “Homosexuality as a Consequence of Epigenetically Canalized Sexual Development” What makes this theory so compelling is how it addresses the “heritable but not at all clearly genetic” problem of explaining the very high prevalence of homosexuality in human populations. There have been other theories of homosexuality that invoke sexual antagonism, but Read More

Ever wonder about the swimming pattern of sperm?

Posted 15 Jul 2013 / 0

Wired “Sperm Trajectories” I like the way that color is used to denote time in these images, and how they show these four different trajectory types in multiple dimensions. Now if we can figure out the evolutionary significance of this diversity, we have a real story.

The potential for human evolution has increased along with the population size of our species

Posted 15 Jul 2013 / 0

Wired “Humanity’s Recent Evolution” Of course increased genetic diversity just makes evolution more possible… but there still still needs to be some viable selective force to do something with all this variation. One could argue that the amount of variation we now see ‘tolerated’ by nature suggests that humans have been released from many selective Read More

Great NPR piece on how simple it would be for us to reduce carbon emissions

Posted 28 Jun 2013 / 0

NPR Planet Money “Economists Have A One-Page Solution To Climate Change” I love this piece because it effectively captures the importance of an across-the-board carbon solution. The carbon tax would be relatively easy to enforce, could be used to wean ourselves from carbon-based fuels in a calculated and deliberate manner, and would hurt only those Read More

Working on a VUE concept map of the fieldTest simulation

Posted 22 Jun 2013 / 0

Jennifer Verdolin, Dylan Moore, and I created the fieldTest simulator several years ago. This individual-based simulation allows virtual animals with the potential to form social groups that defend territories to interact on landscapes containing different patterns and abundances of resources, and is part of my larger research into group territorial behavior. We presented our results at the 2009 Read More

Useful guides for writing good pseudocode

Posted 18 Jun 2013 / 0

I am slogging away at writing up a long-overdue individual-based modeling project that I presented eons ago at ESA 2009 and ESA 2010, and I am trying my best to present the model in complete form. This project is the result of a lot of work by me and my collaborators Jennifer Verdolin and Dylan Read More

The benefits of a maintaining a relatively small in-group

Posted 29 May 2013 / 1

WNYC Micropolis “Hasidic Supermarkets and the Virtues of Insularity” Although I think that this is an interesting little feature, it mistakenly attributes the benefits of this trust to a lack of diversity. What allows this trust is a relatively small, highly-integrated society. If the larger city lacks anything, it is the level of social integration Read More

Pratt Professor Ágnes Mócsy releases “Smashing Matters” short film

Posted 21 May 2013 / 0

A colleague of mine, Associate Professor Ágnes Mócsy, just released her first short film, smashing matters: Featuring a really broad array of eminent physics researchers, this film uses the Relativistic Heavy Ion Collider as a case study for how funding basic science research leads to social progress. Although I am not predisposed to believing that all basic Read More

Pratt Institute holds 124th Commencement, special gallery show

Posted 14 May 2013 / 0

Pratt celebrated its 124th commencement ceremony at Manhattan’s Radio City Music Hall on Tuesday, May 14th, 2013. I always try to make it to graduation to honor the hard work of our graduating seniors. Although there are usually a few students graduating who I worked with closely, mostly I go to see the many students Read More
