Can understanding cooperation lead to higher-yield crops?

Posted 07 Jan 2016 / 0

The Scientist “The Evolution of Cooperation” Starting with the title, this short article is not bringing anything all that new to the existing literature on how cooperation evolves. But once I realized that this piece was really about the direction of Denison’s research on rhizobia, the rest of the basic background made a lot more Read More

Is family-linked terrorism a cultural and genetic phenomenon?

Posted 03 Dec 2015 / 0

National Public Radio “In Worst Attacks, Terrorists Often Have Fraternal Bonds” This is an interesting — albeit brief — piece on a recent “pattern” that has emerged in terror attacks: teams of attackers are often composed of blood relatives. As a good scientist I have to point out that there’s a danger here of over-generalizing Read More

New report on drug resistance highlights the tragedy of our antibiotics commons

Posted 02 Oct 2015 / 0

National Geographic Germination blog “Antibiotic Resistance Getting Worse Globally, But Fixes Could Be Simple” Antibiotic resistance is an interesting problem because it highlights how individual decisions drive international-scale dynamics and then come right back to impact individuals. Unlike other big international tragedies of the commons such as climate change or fisheries collapse, the effects of Read More

Zoonosis, Ebola, and the Elusive Reservoir Host

Posted 24 Jun 2015 / 0

There’s a really interesting article in the upcoming (July 2015) issue of National Geographic entitled “Stalking a Killer“. Using the most recent outbreak of Ebola in West Africa as a case study, the article looks at the nature of a variety of unusual and rare diseases caused by filoviruses. Ebola is not a virus that Read More

Evolution 2014: Day 1

Posted 21 Jun 2014 / 0

My first session of the day was spent entirely in a Symbiosis session. I am fascinated by symbiosis, particularly mutualistic symbiosis, so I am always looking for cool new stories to help illustrate the concept for my students. This session featured a lot of talks on microbial symbionts, which are also of interest to me. The Read More

Evolution 2014: Could the right symbionts provide protection from chytrid infection to amphibians?

Posted 21 Jun 2014 / 0

Patrick McLaughlin showed work on Bioko Island suggesting that frogs there may be protected from the ill effects of chytrid infection by the presence of bacterial symbionts. These symbionts produce metabolites that lower rates of parasitic infection, suggesting that symbionts might be used to protect amphibian populations worldwide. It also suggests a mechanism by which Read More

Evolution 2014: Aphids protect themselves from parasitoids by harboring a bacteria whose viral parasite is toxic

Posted 21 Jun 2014 / 0

Andrew Smith of Drexel University spoke about a four-species interaction that could best be described as “my symbiont’s enemy is my parasitoid’s toxic enemy” scenario. Aphids can avoid being parasitized by a parasitoid wasp if they harbor particular bacterial strains. What’s interesting is that the bacteria don’t directly confer resistance to the parasitoid: instead, it is the Read More

Once considered clear, the line between ecological and evolutionary time scales is becoming more blurry

Posted 25 Jan 2014 / 0

The Chronicle of Higher Education “What Darwin Got Wrong” Great article on the importance of better understanding rapid and/or fluctuating evolution! The number of applications to applied human issues is fascinating.

Caterpillars weaponize nicotine

Posted 02 Jan 2014 / 0

The Economist “Caterpillars that blow nicotine at their enemy” I love the combination of genetic manipulation and “arena of death” wolf-spider gauntlet that led to these findings.
