Chaco before Chaco: The Basketmaker III Period

by teofilo in Gambler's House

The Basketmaker III period (ca. AD 500 to 750) is a very important time for understanding the prehistoric Southwest.  Maize agriculture had been introduced earlier, although exactly how early is still a matter of debate, and it was definitely well-established by the immediately preceding Basketmaker II period, but Basketmaker III saw the introduction of beans, [...]...

JAMA on 60s Psychedelic Drug Culture

by The Neurocritic in The Neurocritic

An amusing semi-anthropological study was published in JAMA by Ludwig and Levine in 1965. It was based on extensive interviews with 27 "postnarcotic drug addict inpatients" who were treated at a hospital in Lexington, Kentucky. The specific drugs of interest included peyote (from the peyotl cactus plant), mescaline, LSD, and psilocybin. The current availability of each drug, most popular methods of intake, slang terms, psychoactive properties, and subcultural norms were discussed. Hallucinogens ........ Read more »

Stuck in a bad relationship are you?  Join the club.  Many members of the animal kingdom are ‘doing it’ with mediocre mates on a daily basis for a variety of reasons including the lack of ability to find someone better, forced copulations, social protocols and much more.  But have you ever considered that hooking up [...]...

Increase in number of eating occasions, more than increases in food portion sizes or energy density per meal responsible for increased energy intake at the population level?

by Colby in

We know by now that an increase in calorie consumption since the 1970s by about 500 Calories per day for Americans is primarily fueling obesity.  Physical activity decline at the population level is a lesser contributor (and it is contentious … Continue reading →... Read more »

Persistent Insomnia in Depression Responding to Antidepressants

by William Yates, M.D. in Brain Posts

Sleep problems commonly occur as part of a problem with mood disorders including depression.  Changes in sleep duration (insomnia or hypersomnia) are one of the criteria for the diagnosis of depression in the Diagnostic and Statistical Manual of Mental Disorders.  Although not absolutely required for the diagnosis, insomnia is a complaint in the the majority of subjects presenting for clinical trials in the treatment of depression.The selective serotonin reuptake inhibitors (SS........

Increasing fruit & veggie intake - the why and the how

by Megan Carter in Verdant Nation

Today’s post focuses on why you should eat yer fruits and vegetables, and how we may be able to get more of us to do so.  At a population level, the evidence for increasing fruit and vegetable (F&V) consumption and decreasing obesity isn’t super strong [1]. But I still think that it’s at the heart of how to make a healthy population – coupled of course, with decreasing intake of crappy, energy dense, nutrient poor snack foods and sugar-sweetened beverages, as well as growing food in sus........

Two or one species? - A 134 year old snakehead story

by David Lagman in Fish addict...

For some reason I find it interesting when studies aim to sort out difficult problems such as distinguishing different species or resolving the evolutionary history of species, in particular vertebrate species. Therefore I happened to stumble across this study published 24 of June this year PLoS One. They looked at two species of fish within a family called snakeheads Channidae. These fish have a long slender body for fast stealthy attacks sort of like the eurasian and north american Pike (genus........ Read more »

Cultural Custom-Fitting to Combat Obesity

by Rob Mitchum in ScienceLife

Countless campaigns have been launched to steer schoolchildren toward healthy habits, and yet rates of childhood obesity and diabetes continue to soar. Celebrity endorsements, catchy catchphrases, and food pyramid redesigns have struggled to combat the allure of fast food and television in the battle for child health in the United States. But with childhood obesity [...]... Read more »

Task Specific Devices and the Perceptual Bottleneck

by Andrew Wilson in Notes from Two Scientific Psychologists

I've been wanting to blog this paper, Bingham (1988; download link), for some time, and I've had the excuse to be reading it this week as I develop a grant. There's a lot here, and many of these brief points are worth posts in and of themselves. My goal here was to create a walk through of the paper, and I hope to dive into some of these issues in more detail.This paper comes from Geoff Bingham, my PhD advisor at IU. And, like most of the good things Geoff has taught me over the years, this pape........ Read more »

This is your brain in the city

by Tim De Chant in Per Square Mile

For a kid who spent much of his childhood outdoors—alternately splitting time between the wooded park down the street, my friends’ backyards, and a patch of countryside my parent’s tended—I have been spending a lot of time in rather large cities as an adult. Ever since I left college, I’ve lived in cities that count [...]... Read more »
