Spirit Possession in Uganda

by Tom Rees in Epiphenom

Spirit possession is common in Uganda, as it is in many parts of the world - especially impoverished areas. It's a complex syndrome, however, with different spirits have different effects.

In Runyankore, the local language spoken by the Banyankore of Southwestern Uganda, possession by evil spirits is known as Okutembwa and can result in the patient talking in another voice. Possession by the spirits known as Okugwa leads to shaking and falling down. Other spirits can induce a trance-like state......... Read more »

Implementing Twitter in a Health Sciences Library

by Laika in Laika's Medliblog

Twitter describes itself as “a service for friends, family, and co-workers to communicate and stay connected through the exchange of quick, frequent answers to one simple question: What are you doing?” [2]. The “answers” are equally simple, because the tweet (that what is being “said”) must fit in 140 characters. The tweet does not only [...]... Read more »

Drug Development for Cognitive Enhancement

by William Yates, M.D. in Brain Posts

AMPA (α-amino-3-hydroxyl-5-methyl-4-isoxazole-propionate)Cognitive enhancement seeks to improve cognitive function in healthy adults.  Although medicine typically focuses on treatment of medical disorders, a significant effort is underway to explore the mechanism of human attention, concentration, memory and other cognitive functions.  Cognitive enhancement does not replace other methods of cognitive performance.  There is no substitute for repetitive practice and learning conten........

Land Deal

by Journal Watch Online in Journal Watch Online

Cheaper can be better when it comes to conservation. That’s the message from a new study that examines the most cost-effective way to protect 10% of Argentina’s vast grassland ecosystem. The approach suggests that putting a premium on saving the most biologically-important lands may not always be the most realistic approach.
Global conservation groups often […] Read More »... Read more »

Global Warming Warnings Can Backfire

Developing a set-back plan in pain management

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

Without a doubt, anyone reading my blog will have tried at some point to change a habit.  Maybe to stop drinking coffee (why?!), start doing more exercise, say no to new projects, eat more fibre – even when a decision to make a change is not done of a New Year’s Eve, chances are that … Read more...

A new squid and an old octopod

by Mike Mike in Cephalove

I always sneer when species are described as “new”. Obviously, few species are anything like “new” – really we mean “newly discovered by science.” Anyways, the big news is that a previously undescribed species of squid was discovered by an IUCN-affiliated scientist from a sample taken in the southern Indian Ocean. A formal description is [...]... Read more »

The Many Lives of Smilodon

by Laelaps in Laelaps

On a superficial level, the predatory habits of the saber-toothed cat Smilodon would not seem to be especially mysterious. Traditionally – and incorrectly – restored as a lion with extra-long upper canines, this felid obviously used its fearsome dentition to dispatch the large prey of its Pleistocene heyday.
Of course, things aren’t as simple as that. [...]... Read more »

Two New Dinosaurs From Utah: Hippodraco and Iguanacolossus

by Brian Switek in Dinosaur Tracking

The parade of new dinosaur species continues this week with the description of two new iguanodont dinosaurs from Utah: Hippodraco and Iguanacolossus. Iguanodont dinosaurs were among the first to be discovered by scientists. The genus Iguanodon itself was described by the English naturalist Gideon Mantell in 1825, although the way he initially envisioned it—as a [...]... Read more »

Breaking Biofilms with DNA

by Lab Rat in Lab Rat

I've written about biofilms a couple of times before but it's an interesting enough topic to keep returning to. As a brief summery, biofilms are large collected colonies of bacteria, often surrounded by a sticky mesh of glycoproteins. They are ultra-annoying in the case of infectious bacteria as the bacteria deep in the depths of the biofilm will not be exposed to any antibiotics, the layers of glycoprotein and surrounding bacteria will protect them.Although living within a biofilm contains sig........

Cancer Disparities at an Early Age

by Rob Mitchum in ScienceLife

Racial disparities have been described for almost every type of cancer, with the gap in outcomes widening or holding steady between black and white patients in breast, prostate, colorectal, and lung cancers. Much debate has occurred over the causes of these disparities, with most  focusing on the overlapping factors of socioeconomic status, access to health [...]... Read more »

Deep-Water Sand Dunes in the South China Sea

by Brian Romans in Clastic Detritus

When you think of sand dunes you most likely picture the vast sand seas of the Sahara Desert or perhaps ancient dunes preserved in rocks on display in places like Zion National Park. Sand dunes are the textbook example illustrating how moving fluid constructs and interacts with piles of loose sediment.
But wind isn’t the only [...]... Read more »

The Fingerprint of Fishing

by jebyrnes in I'm a chordata, urochordata!

How is fishing changing the ocean? This simple question has motivated a slew of fantastic research. One of the most pervasive ideas has been that of Fishing Down Marine Food Webs. Popularized by Daniel Pauly and colleagues in their 1998 paper, the idea simply states that when humans began fishing, we hit the top predators first. Gradually, as we depleted those stocks, human fishing moved down to the next trophic level. And the next. And the next.... Read more »

No, I will not run the Seattle Marathon barefoot

by Jeremy Yoder in Denim and Tweed

I'm spending a significant chunk of my Thanksgiving break in Seattle, for the purpose of running what will be my second marathon this weekend. Running, like cooking, is helping to keep me sane in the midst of teaching labs, finishing my dissertation research, writing said research up for publication, and trying to sort out what happens after my committee decides I've earned a handful of extra letters after my name.

Enculturation of Music: Does Age or Complexity Matter?

by Psychology 379 bloggers in Cognition & the Arts

Have you wondered if the child in the backseat is noticing the different songs that have come on the radio? Or have you ever been listening to NPR and the music suddenly changes from a classical Western piece to an instrumental piece of an unfamiliar type? Now, would the child in the backseat notice such a song change? A recent study shows that children and adults do not differ in a memory task identifying music selections based on music culture type (familiar or unfamiliar). Their findings........ Read more »

purple pain and a gene called 'straightjacket'

by Chris in The Lousy Linguist

Dr. Kevin Mitchell, a neuroscientist at Smurfit Institute of Genetics, University of Dublin, posted at his excellent blog Wiring the Brain about a weird, interesting study* that points to a possible genetic explanation of synaesthesia** (e.g., hearing a word and experience the color red). The authors were studying pain mechanisms in fruit flies (turns out the mechanisms are similar to us mammals, whuddathunk?). Once they identified a particular gene they dubbed straightjacket*** which is "involv........ Read more »

Beliefs About Infant Growth may Determine Childhood Obesity

by Arya M. Sharma in Dr. Sharma's Obesity Notes

Regular readers are well aware of the accumulating evidence that early childhood influences may play a major role in the development of childhood and adult obesity.
Many of these influences may result from parental response to infant temperament and parental perception of infant growth and appetite.
These issues were further explored by Sarah Redsell and colleagues [...]... Read more »
