Nineteen Eighty — if I had to pick the year that computational modeling invaded evolutionary game theory then that would be it. In March, 1980 — exactly thirty-five years ago — was when Robert Axelrod, a professor of political science at University of Michigan, published the results of his first tournament for iterated prisoner’s dilemma […]...

Strategies and practices to achieve supply chain resilience have been at the heart of supply chain management practice and research for almost a decade. However, such efforts have often focused on ways to make supply chains more reactive to turbulence and disruptions. In our recent article, Antecedents and Dimensions of Supply Chain Robustness, my co-authors, Christian […]... Read more »

People say to avoid processed foods, while I don’t agree with that fully, a new study suggests that a common food additive may be causing problems. Emulsifiers, which are added to most processed foods to aid texture and extend shelf life, can alter the gut microbiota composition and localization to induce intestinal inflammation that promotes the development of inflammatory bowel disease and metabolic syndrome....

There’s a well studied phenomenon called Terror Management Theory which basically says that, when people are reminded of their own death, their beliefs change in certain predictable ways. People cling more strongly to beliefs that make the future seem more controllable and comfortable – and that includes turning to religion (see: Religion, Patriotism and Death). [Read More...]...

Alternative fuels have a few large problems making them horrible options over oil (which is already a horrible choice). However, researchers may have finally eliminated one of those problems, cost. The team has invented a novel pretreatment technology that could cut the cost of biofuels production by about 30 percent or more by dramatically reducing the amount of enzymes needed to breakdown the raw materials that form biofuels....

Nothing turns your internet procrastination time into feelings of goodwill and teamwork like a citizen science project. You can click through a set of penguin photos or moon craters and know that your data are contributing to real science. As more citizens take part, and more researchers discover the joys of free labor, these projects are gaining popularity. But not all citizen scientists pull their weight. In fact, most do nearly nothing.

In a new paper, a group of MIT researchers argue that science is producing PhDs in far greater numbers than there are available tenured jobs for them to fill.
The authors, engineers Richard C. Larson, Navid Ghaffarzadegan, and Yi Xue, start out by noting that
The academic job market has become more and more competitive... nowadays, less than 17% of new PhDs in science, engineering and health-related fields find tenure-track positions within 3 years after graduation.

Ever go shopping when you’re hungry and notice you walked out with a lot more than you were expecting to buy? While most people know that when you are hungry, you typically will buy more food (as illustrated by The Oatmeal above), new research shows that there is a clear link between hunger and buying non-food items. A team of international researchers has released a paper that describes five laboratory and field studies they conducted which showed how people respond to non-food objects when ........ Read more »

Happy valentines day! Okay maybe it’s turned into more of a reason to spend money on chocolate and flowers than it is about showing affection — which is probably why some people hate it — but it can still be a somewhat special day.

As anyone who's made valentines for a whole elementary-school class knows, kids are often pushed into social groups not of their choosing. Scientists tried the same thing with wild birds and found it pretty easy to coax them into new cliques. The birds hung out with their new social circles even when they didn't have to. But once the experiment ended, those friendships dissolved faster than a candy conversation heart.
To create new social groups in birds, researchers essentially controlle... Read more »

My Valentine’s Day themed posts have been both popular and fun to write. In last year’s Getting a Date for Valentine’s Day series, you learned that you should wear something red, gaze without being creepy, tell a good joke before walking up to your potential date who is preferably standing next to some flowers, and then open with a unique request to segue into asking them out. But that isn't the end of the story. Oh no, there are many more things that you can do to attract that special so........ Read more »
