2:22 PM | Hunger in Egypt
In 2008, before the revolution, the Egyptian Government set a portion of its Army to baking bread for hungry citizens, precisely to forestall revolution.  Now, after revolution, it isn’t clear who will provide the bread for its hungry and angry populace: Around a quarter of the population lives below the poverty line, with another 20 percent…

2:12 PM | Even in France…
Fast food sales now outnumber sit-down restaurant food sales in the home of gastronomy: More than half of all French restaurant sales now take place, sacrilegiously, at fast food chains, according to a new survey by food consultancy firm Gira Conseil. This is the first time fast food sales have surpassed sit-down restaurant sales in…

1:44 PM | The young and the restless
It struck me recently that one of the key differences between economists and neuroscientists studying decision-making is their interest in dynamics.  Economists seem more interested in explaining how behavior operates (or should operate) on average whereas neuroscientists would like to explain trial-to-trial variability.  Decisions are rarely made just once in a lifetime, but are instead made repeatedly.

12:11 PM | Getting and running a big site grant in a small institution: how collaborations fail
Here’s the message of the post in a single sentence: You need open communication and collaboration to land and run a successful site grant, and petty concerns about sharing resources could mean that nobody gets anything. Now here’s the rationale: “Site grants” power research centers and student training programs. Research institutions are expected to have [...]

4:23 PM | Economics of Social Status
In economic terms, for a good to function as money it must serve three related purposes: A medium of exchange, A store of value, and A unit of account. We’ve already discussed how status functions as a medium of exchange. Because it’s so fluid, it can be used to price favors and other goods at relatively [...]

Hello: I am an avid diver and lay scientist.  I took the attached photo at Rock Lake, NM which I hypothesize is the world's highest cenote at 4,600 ft. above sea level...I would prefer to know a bit about the subject of my photo, so I may give it due credit and hopefully bring positive attention to them. In this quest I came upon your name and therefore duly appreciate the offer given in your

9:23 PM | Newborn screening: One of public health’s greatest achievements celebrates 50 years and thousands of lives saved
On Feb. 13, 2012, Honey Stecken gave birth to her daughter Maren. Everything appeared perfectly fine — she ate and slept and did all the things a baby does. Even after a couple weeks at home in South Fork. Colo., with her newborn little girl, nothing seemed out of the ordinary.

3:56 PM | Global warming since 1999
Climate change deniers like to claim there has been “no warming since 1998″ which was an especially warm year due to an intense El Nino.  Well that ain’t true.  Global warming has indeed continued, especially in the deep sea due to the prevalence of several La Nina events recently. Here is how much the land [...]

12:25 PM | Getting past the comic stereotype of grad student life
I loved grad school. I have serious nostalgia for grad school. If I could be a grad student forever, that would rock. In fact, my job as a faculty member is a lot like being a grad student. I do research, I teach, I write grants, I write manuscripts, I work with students less experienced [...]

Carnival of Evolution #59 is up!  Our contribution is Thomas Cameron's recent piece Of Mites and Men, about some fascinating experiments into harvest-induced selection.  Lots of other good stuff in there, check it out!The theme this month is, somewhat bizarrely, Doctor Who.  It has nothing to do with evolution, but I'll leave you with a picture of Sarah Jane Smith, a companion of the 3rd and 4th Doctors, played by Elisabeth Sladen.  I watched Doctor Who more or less nonstop […]

12:45 AM | Humans are causing more strong hurricanes
The possible effect of global warming on the frequency or severity of cyclonic storms has been debated quite intensely among scientists (not only between scientists and climate change deniers) for over a decade.  Several new studies are helping to clarify (somewhat) whether we are already experiencing (or will soon) more intense storms.  Dana Nuccitelli has a [...]

9:39 PM | Jumping off of bridges
No man is an island, entire of itself.  Although we like to think of our decisions occurring in a vacuum, in reality we’re bombarded with information on how other people are deciding all the time.  It would be shocking if our decisions weren’t influenced by the behavior of other people – and, obviously, a wide range [...]
