Following up on the recent discovery that novelist and lepidopterist Vladimir Nabokov correctly supposed that Polyommatus blue butterflies colonized the New World in stages, Jessica Palmer points out that none other than Stephen Jay Gould dismissed Nabokov's scientific work as not up to the same standards of genius exhibited in his novels. She suggests that Nabokov's work may have been dismissed by his contemporaries because his scientific papers were a little too colorfully written.Roger Vila, ........ Read more »

The average length of a night of sleep for an adult in the United States has decreased by 2 hours in the last 50 years. Increasing evidence reports the damaging effects of sleep deprivation and restriction on hormone release, cardiovascular function, and glucose regulation. Now, in fact, evidence shows that sleep loss undermines dietary efforts [...]... Read more »

Swedish researchers reported recently that a Paleolithic diet was more satiating than a Mediterranean-style diet, when compared on a calorie-for-calorie basis in heart patients. Both groups of study subjects reported equal degrees of satiety, but the paleo dieters ended up eating 24% fewer calories over the 12-week study.
The main differences in the diets were that [...]... Read more »

So, welcome to the first Egypt Week edition of Lost in Transcription. We're going to kick it off with an anthropology paper that uses a cross-cultural approach to study the origins of human punishment and cooperation.
If you're not familiar with this vein of research, let me set the stage for you. The "problem" of cooperation when people talk about it in anthropology, biology, and economics is this. If you take a super naive view of natural selection, it would say that we shou........ Read more »

Modern cities generate huge amounts of rubbish, and disposing of this is one of the most pressing environmental problems. One can bury it of course, or burn it in incinerators, or just dump it in a big pile just outside the city. This is the approach chosen for the Jardim Gramacho in Rio, Brazil, one of the worlds largest rubbish dumps, which is the subject of the Oscar nominated film, Waste Land.*Seventy percent of Rio's rubbish arrives at Jardim Gramacho, which is an astonishing 7,0........

By now many have heard about the recent study published in Pediatrics which, of course, shows a clear link between extensive video game playing and depression in teenagers. You may have also heard about another recent publication of a study conducted by 8-10 year olds.
"How are these studies related?" You may ask.
"They are not." I may respond. Actually I will respond. These studies have nothing to do with each other. However, they are related from the perspective that they are BIG news!

An economist typically bases their economic models on an assumption that the economy is composed of agents who gain utility from consumption. From the beginning of the model, they take consumption to be the objective and all decisions by the agents aim to maximise their level of consumption within the budget constraint that they face. While I recently posted on how most economists’ fixation on [...]... Read more »

By: Dr. Shelley Spiecker Six months after the public was riveted to press coverage of the oil spill in the Gulf, impact on energy defendants has been less doomsday than feared. In fact, this is one of the better times in the past 10 years to be an energy defendant in front of a jury. Why? Much as the spill itself appeared to dissipate more rapidly than expected, the tide of public opinion has drifted away from concern over the environmental practices of energy companies, and toward concern over ........

Oh, how I love science.
But, I digress.
For a few years now countless food manufacturers have been “sub-packaging” their foods into smaller portions in an apparent effort to curb folks from overindulging.
