Do cancer cells play cooperate in the Prisoner’s Dilemma?

Posted 26 Jul 2014 / 0

PLoS One “Prisoner’s Dilemma in Cancer Metabolism” What is interesting here is that cancer cells must cooperate with each other in order to out-compete somatic cells against a staggering cost-to-benefit ratio. Generated by the extreme inefficiency of anaerobic metabolism, this ratio presents a supreme challenge to a developing tumor, which might be one factor explaining Read More

My Evolution 2014 talk is on YouTube

Posted 17 Jul 2014 / 0

One nice thing that organizers of the Evolution 2014 conference did was to offer the opportunity for presenters to have their talk recorded and archived. These recorded talks now have their own Evolution 2014 YouTube Channel, and my talk is included in this collection: This was an experiment for this conference, and I think that it came Read More

Evolution 2014: Day 0

Posted 20 Jun 2014 / 0

I started off this year’s Evolution meeting early. The conference is — at its core —  a four-day affair. But the days leading into the “official” start on Friday evening feature larger workshops aimed at building skills. I chose to attend the Experiencing Evolution workshop. Here’s what this session promised: Evolution is a key biological concept, Read More

EnviroAtlas is now live, publicly available

Posted 30 May 2014 / 0

For the past couple of years I have been playing around with a really cool tool called EnviroAtlas, a project of the U.S. Environmental Protection Agency. This past semester I created two classroom activities that use EnviroAtlas, implementing them for the first time in my Ecology for Architects course. The EnviroAtlas tool was in beta-testing Read More

John Oliver holds first “balanced” climate debate on television

Posted 30 May 2014 / 0

Very nicely done! The monologue is great, but then the “performance” of the balanced climate change debate is really what drives home the point here. Don’t watch networks that present false “debates”.

Cath Dennis publishes non-computerized classroom adaptation of Axelrod’s iPD Tournament

Posted 30 May 2014 / 0

I have corresponded with Cath Dennis of the University of Aberdeen, as we both share an interest in how to bring some of the foundational work exploring cooperation into our classrooms. She has just published one of her classroom activities — an “analog” version of Robert Axelrod’s iPD tournaments — in the Journal of Biological Education.

The Chronicle of Higher Education “Dolphin Talk and Human Credulity” Great short here (and further evidence that TED Talks entice scientists to lose their heads and say unfounded things). Anyone who has carefully watched a child learn to talk comes to realize what a complex dance between cognition anatomical coordination is involved in language acquisition. It is Read More

Is “nest parasitism” really “nest mutualism”?

Posted 20 May 2014 / 0

NPR All Things Considered “This Freeloading Bird Brings Help — And The Help Smells Gross” It is hard to believe that feeding an entire extra non-offspring would be in the self-interest of a bird, but as this short points out, costs and benefits are always environment-specific. In this case, the “parasitic” effect of having to raise Read More
