Arrangement for psychotherapy fMRI studies using the couch of Sigmund Freud.[No not really, although the authors did stretch the implications of their findings in the Discussion...]Whether the proprietors of this blog want to admit it or not, neuropsychoanalysis appears to be a new field of study. What does psychoanalysis do to the brain? In a new Psychotherapy Research paper, Loughead et al. (2010) collected autobiographical relationship narratives from 16 healthy control participants free of a........ Read more »

Author’s note: This would seem to be the week for vegetables I hated as a kid. Yesterday was onion, today tomato, if there’s a story about brinjal/eggplant in the next few days we’ll have hit all the big ones.

A recent article (Sutherland et al. 2010) from Trends in Ecology and Evolution provides insight on several emerging research areas through a practice called ‘horizon scanning’—really, a sciency way to say that the authors shortlisted environmental issues that they collectively felt were important, merited further discussion, and could effect biodiversity. The point is made that [...]... Read more »

I'm heading off for a weekend away as soon as my other half wakes up, so no time for a proper paper analysis today, just a quick video of some algae dancing:The organisms shown above are microalgae called Volvox carteri. The large circle is a surrounding membrane which holds within it normal volvox cells (the little white spots) and larger germ line cells (the large white spots) which later hatch to form new Volvox. The reason the three cells above look like they're dancing is because they move ........ Read more »

Widely reported earlier this week was a study on prayer and forgiveness. It's by the same crew that gave us the study last year on prayer and gratitude, and has (broadly speaking) the same methodological concerns (it only recruited students who already pray, and uses measures that are difficult to interpret).But, fair doos, this is an interventional study of the effects of prayer that is basically sound, and the authors deserve kudos for trying to assess this unfashionable area. So what did it s........ Read more »

Growing up in New Hampshire, I took the yearly migration of ducks, geese, and (less obviously, but more impressively) Monarch butterflies pretty much for granted. It never really occurred to me to ask why all of these animals migrate. If I had been asked, I probably would have made the (common) anthropomorphic fallacy and said that they migrate because they "want to," or because they "like it better" at their ultimate destination.Think about it: migration--especially very long-distance migration........

No one can deny that the field of science is undergoing explosive growth. The “technological age” has treated it kindly, giving it both access to new equipment and techniques, as well as creating a larger scientific community with more connections between labs around the world. We are bombarded with information in general: hundreds of papers [...]... Read more »
According to researchers at the University of Maryland, Egyptian fruit bats, unlike their American relative the big brown bat, locate objects through a series of tongue clicks directed to either side of their target.
Big brown bats locate their fast moving prey—such as mosquitos—by firing sounds from their vocal cords directly at their target. Egyptian bats, [...]

There's a nice review on GPCRs and their continuing challenges in the British Journal of Pharmacology this month. The authors focus on both structural and functional challenges in the characterization of this most important class of signaling proteins. As is well-known, drugs targeting GPCRs generate the highest revenue among all drugs. And given their basic roles in signal transduction, GPCRs are also clearly very important from an academic standpoint. Yet there is a wall of obstacles confronti........ Read more »

The whole world of exergaming (using video games as a means to get exercise) really came to the forefront when the Nintendo Wii first came out, complete with remotes that you actually had to move in space rather than just pushing a button or two. In time they also added a balance board as part of the Wii Fit game series which involved your whole body and not just your hands. More recently, EA sports created a new series of active games for the Nintendo Wii (Wii Active) which uses a legstrap for ........ Read more »
