Where They Got the Turquoise

by teofilo in Gambler's House

Probably no single material is more closely associated with Chaco than turquoise.  The vast amounts found in Room 33 at Pueblo Bonito alone suggest its importance, but it has been found in considerable quantities at many different sites, both small houses and great houses and both inside and outside of the canyon.  There is considerable [...]...

Am happy, will be selfish; Am sad, will be fair. Oh Really?!?

Many a times, researchers have their own personal agendas and its very human to fall in to the temptation to interpret study results or spin them to suit ones long term subject matter and expertise.  This is a trap in which Joe Forgas et al fall when they report in JESP that happy More >Rating: 0.0/10 (0 votes cast)

Sunlight on the sea

by Sarah Stephen in An ecological oratorio

In this last week the Brazilian cities of Sao Paulo and Recife have experienced records levels of UV exposure. While a UV index of 6-7 is ¨high risk", and "very high risk" is 8-10, Sao Paulo was scorched with an index of 14. As the sun burns us it also beats down on the ocean surface and the algae that live there. What happens next is the subject of the CLAW hypothesis, which proposes a negative feedback loop, as follows.....Dimethylsulphide produced by phytoplankton is oxidised by bacteria to ........

Workplace Interventions Increase Employee Physical Activity Levels

by Travis Saunders, MSc in Obesity Panacea

Although it is widely recommended that adults attain at least 30 minutes of moderate intensity physical activity on most days of the week, over half of Americans (51.9%) and Canadians (51.0%) fail to meet this minimum threshold. While physicians may also counsel their at-risk patients regarding physical activity, these patients seldom adopt the recommended behavior. Thus, while we currently know that physical activity is good for most people, we don’t have the vaguest idea how to get most ........ Read more »

Musical Emotions: Chills Edition

by Princess Ojiaku in Science with Moxie

CHILLS.I'm one of the people who gets them when I listen to music I find really, really enjoyable. In fact, there are a whole range of emotions I can go through while listening to something I really like. Last Saturday night, I definitely was on the peak end of experiencing intense music-related emotions while watching my bandmate and favorite drummer, Jessica Caesar play during this song at The Dirty Little Heaters' CD release show. Take a look:So what is this whole "chills" thing about anyway?........ Read more »

Can birds affect tree growth?

by Katie Kline in EcoTone

Growing conditions, such as water and nutrient supply, are the major determinates of tree growth, but insectivorous birds can also play an important role, say scientists in a study published in the January issue of Ecology. Under the right conditions, birds contribute to whole tree growth by preying on herbaceous arthropods, such as leafhoppers, caterpillars and grasshoppers.... Read more »

The ant smelloscope

by Zen Faulkes in NeuroDojo

Blast it, I hate it when the authors of a research article come up perhaps the best possible title.

“Do desert ants smell the scenery in stereo?”

I can’t top that title. All I can do is try to explain a little.

Cataglyphis fortis is a name that is not well-known to many, but to an ethologist like myself, they're kind of famous. This is a desert ant species that has taught us a phenomenal amount about how animals navigate in their environment. These ants, with their small brains, are doi........ Read more »

Video-game exercise bikes - not just a gimmick

by BPS Research Digest in BPS Research Digest

Exercise is going techno. People are playing Wii fit sports games in their homes and gyms are full of ever more interactive exercise machines. But is this trend anything more than gimmickry? Yes, according to a new study by Ryan Rhodes at the Behavioural Medicine Lab at the University of Victoria, and his colleagues.Rhodes' team had 29 previously inactive young men embark on an exercise regime, involving three half-hour cycling sessions a week for six weeks. Crucially, half the men trained on Ga........ Read more »

Personalized Annoyance of Research Enthusiast (PARE)

by Keith Robison in Omics! Omics!

Last night I finally got my paws on a paper which started out on a frustrating tack. Last week, a flurry of news items heralded a new approach from Vogelstein's group at Johns Hopkins that involved second generation sequencing of patient tumor samples. But, the early reports claimed it had been published in Science Translational Medicine, whereas it most certainly wasn't there except a suggestive teaser about the next week's issue. I thought perhaps someone had really blown it and ignored an ........ Read more »

Why Johnny can’t read (but Jane can)

by Kevin Mitchell in Wiring the Brain

Reading is not a skill that comes naturally.  Unlike learning spoken language, which the human brain has evolved to absorb almost effortlessly, learning to read is a protracted and difficult process.  It involves the categorical association of arbitrary visual symbols with phonemes and also the ability to break words down into component phonemes.  It thus relies on an integration between visual and auditory processes, combining spatial and temporal information, within a learned linguistic c........

Demerol is Not Bad, It Treats Shivering.

by Christian Sinclair, MD in Pallimed: a Hospice & Palliative Medicine Blog

Image via WikipediaIf you have spent anytime with a palliative care team in a hospital you will know of their efforts to essentially blacklist Demerol (meperidine) from use in the hospital.  Some hospitals have removed it or restricted it from the formulary all together.  In medical culture, demerol has been a go to opioid peri-OR and mostly favored by surgeons.  The drug has been purported to be less likely to cause billiary spasm, but this seems to be impacted more by cultural i........

Friday Weird Science: Doing your Kegels to Improve your Orgasms

by Evil Monkey in Neurotopia

Many of you may have heard from your doctor that doing Kegels is a good thing. It's certainly good for keeping your pelvic floor strong, to prevent problems like uterine prolapse following birth. It's also very good for keeping your bladder good and functional later in life. So do your Kegels, ladies.

However, Sci has always heard through the grapevine that Kegels were also good for...other things.

Well, are they?

Nucleotide diversity - what two new African genomes mean

by David in The Atavism


If you wanted evidence that we live in a post-genomic age you would need to look no further than the headlines in the science section of the newspaper last week. A man dubbed Inuk who lived and died in Greenland 4 000 years ago had dry earwax and might have gone bald if he lived long enough, Tutankhamun was inbred and had a cleft palate and Desmond Tutu has had his whole genome sequenced. What about the science behind the hook? Ed Yong has the the story of Inuk (whose genes tell us about migrat........ Read more »

XMRV not detected in Dutch chronic fatigue patients

by Vincent Racaniello in virology blog

The suggestion that the retrovirus XMRV is the etiologic agent of chronic fatigue syndrome (CFS) arose from a study in which the virus was found in 68 of 101 US patients. The virus was not detected in two independent studies of 186 and 170 CFS patients in the United Kingdom. A new Dutch study has also [...]... Read more »

Prion diseases: protein is enough

by Michael Clarkson in Conformational Flux

Spongiform encephalopathies are transmissible diseases that can have a major economic impact on agricultural exports, and pose a significant challenge for surveillance of the food supply. Scientists generally believe that these diseases are transmitted via a self-propagating, aberrant conformation of the prion protein (PrP). This prion hypothesis suggests that PrP alone should be sufficient to cause symptoms or death. If this hypothesis is true, then it should be possible to reproduce the diseas........ Read more »

Is the Clinical Significance Criterion Significant?

by Neuropsych15 in The MacGuffin

The draft version of DSM-V: Revenge of the Fallen has been online for a few weeks (1) and much has already been written about it (1, 2, 3, 4). Much focus has been on what is "new" and what is "gone." One feature that is shared by the majority of DSM diagnoses, the "clinical significance" criterion, might be on its way out. Typically this criterion reads "The symptoms cause clinically significant distress or impairment in social, occupational, or other........
