by Croor Singh in Learning to be Terse

A study that shows that some frugivorous birds can be facultatively ammonotelic. The study proposes that this ammonotely is apparent, and also proposes two mechanisms for the apparent ammonotely.... Read more »

Williams Syndrome, Modularity and Language Evolution

by Hannah Little in A Replicated Typo 2.0

Williams Syndrome (WS) is a rare genetic condition which manifests itself as a severe deficit in development and IQ, however it leaves language ability largely unaffected and is, as a result, often cited as evidence for a specific language module (Bellugi et al. 1988), as language can be unaffected despite other mental deficits. This argument has . . . → Read More: Williams Syndrome, Modularity and Language Evolution... Read more »

Not Paying Cash Means Buying More Junk Food

by David Berreby in Mind Matters

Governments have been trying a lot of new tricks lately to get people to eat more healthily, from calorie-count labels to taxes on soda to banning fast-food outlets from whole neighborhoods. This study suggests a simpler approach might work: It found people buy less junk food when they have to pay ...Read More

Descending inhibitory noxious control. Don’t bite your lip – stand on your opposite toe

by Lorimer Moseley in BodyInMind

Descending modulation, descending inhibition, descending noxious inhibitory control, descending inhibitory noxious control etc etc etc, are used interchangeably and I wish they weren’t. A recent article in PAIN has looked specifically at DNIC – you can work out which term it acronymises (I just made that word up).  Before I give you a very quick [...]... Read more »

Evolving Together: Human Interference Not ALL Bad

by Krystal D'Costa in Anthropology in Practice

Is hindsight really 20/20? When we look at the past, we tend to imagine things as we wish they were, and not recall things as they actually were—nostalgia can be problematic. Romanticism of the past has given rise to ideas like the “Ruined Landscape” or “Lost Eden theory” which create pristine images of the past and argue that human activity is largely to blame for the overall degradation of landscapes. There is no denying that humans have had a lasting impact on the environment, howev........ Read more »

How to Fool a Bat, Pt. II

by clark in Now Hear This

Bats, for all their acoustical superpowers, sometimes fly into stuff. Oddly, the things they often hit are either sufficiently big (like television towers) that a bat ought to be able to echolocate around them, or bright enough — windows, lighthouses — to be visibly seen even with a bat’s relatively poor eyesight. And that’s exactly the problem, it turns out. A recent study in PLoS reveals that bats in the wild collide with objects not because they don’t see them, but because they do. ........ Read more »

Medication and self management for chronic pain

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

Last week a reader asked me for my take on using medications for chronic pain, so today I’m going to take a stab at this rather emotive and certainly very complex topic.  Before I do so, a word of warning – this is mainly my opinion and experience!  I’m also not a medical doctor, I … Read more...

Can obesity surgery for mothers prevent obesity in their children?

by Travis Saunders, MSc in Obesity Panacea

…And we’re back! After a month in exile from the blogging world my comprehensive exams are done!… for now. Assuming that my committee finds my answers satisfactory I will move on to an oral exam sometime between now and the holiday season. The good news is that I have read a ton of papers in the past few months (probably somewhere north of 200) so I’ve found plenty of interesting things to blog about well into the new year!...

Scouting Bees and Fungus-Farming Ants

Siblings Strike Again

by S. Marvin Friedman in Small Things Considered

Bacteria capable of sporulation go out of their way to grow rather than sporulate. They will therefore try to obtain needed nutrients, even at the cost of killing their neighbors. When starved for nutrients, cells of Bacillus subtilis engage in cannibalism, that is they lyse their siblings and use the nutrients thus obtained to postpone their own sporulation. A similar phenomenon, termed fratricide, has been reported in Streptococcus pneumoniae where the killing of siblings is linked to the indu........ Read more »

Urea and Shark Osmoregulation

by WhySharksMatter in Southern Fried Science

One of the challenges inherent in a marine lifestyle is in maintaining an internal balance against external osmotic pressures. Cell membranes are permeable to water, and water tends to flow from areas of low ion concentration to areas of high ion concentration (which is called ‘osmosis’). Though the cell is incredibly complex, from an osmotic perspective [...]... Read more »

Social Cognition in a Non-Social Reptile? Gaze-Following in Red-Footed Tortoises

by Jason Goldman in The Thoughtful Animal

Have you ever been at a party with lots of people chatting away, when for some unexplainable reason you felt compelled to turn and look at the front door of your friend's house...and just as you were looking, someone was just coming in from outside and closing the door? You couldn't have heard the door open since there was so much noise already inside - more likely you noticed that other people were looking at the front door. All of this probably happened without any explicit intention or focu........ Read more »

Does background music aid or impair reading comprehension?

by Psychology 379 bloggers in Cognition & the Arts

Everyone knows someone who likes to listen to some music while they work. Maybe it’s one of your kids, listening to the radio while they try to slog through their homework. Maybe it’s an uncle, playing his favorite record as he reads a book. Or maybe, god forbid, it’s a college senior browsing his iTunes as he desperately writes a last-minute blog post for his psychology seminar. Either way, they’re not alone – it’s a widely held popular belief that listening ........ Read more »
