Societal Assumptions on Abuse and the Victim’s Perspective

by Shaheen Lakhan in Brain Blogger

Sexual abuse of children is morally revolting and a topic wrought with emotions. In the past few decades, awareness of the prevalence of child abuse and its psychological repercussions has increased. A “trauma model” has been built around sexual abuse that perceives it as being directly traumatic and frightening, and necessarily damaging.
Many psychologists now argue [...]... Read more »

by ---a in

So here it is, our little « manifesto for qualitative agent-based simulation » is finally out on the now Sage-published Bulletin of Sociological Methodology/Bulletin de Méthodologie Sociologique. It is just worth stressing the importance of this article in our present research: our effort has been to really provide a comprehensive framework for underdestanding what it means to [...]...

Corruption at health institution

by Bernt Lindtjorn in International Health Research

Corruption at health institution is a concern in all countries, but it is especially in developing countries where public resources are already scarce.
Countries with high indices of corruption have for example higher rates of infant mortality.
A recent World Bank report from Ethiopia (Lindelow and Serneels 2006) report on “pilfering drugs and materials, informal health care [...]... Read more »

One more link between peas and carrots!

by Ramy Aziz in It's a microbeful world

Remember the carotenoids? These antioxidants that also let golden staphylococci resist phagocytosis (1)? A recent study in Science Magazine (2) demonstrates, for the first time, the ability of animals (insects: the pea aphids that infect peas and other plants) to synthesize carotenoids. Well, they didn’t exactly inherit it vertically from their ancestors, but rather got [...]... Read more »

Healthy human carriers of the spirochete Leptospira in the Peruvian Amazon

by Microbe Fan in Spirochetes Unwound

The spirochete Leptospira is the agent of leptospirosis, a zoonosis that primarily burdens tropical regions of the world.  Moist conditions promote the survival of the spirochete Leptospira in soil and fresh water. Although Leptospira could survive out in wet environments if they had to, they thrive in the kidneys of rats and other maintenance hosts, where they form dense masses lining the inner surface of the kidney tubules.  The spirochetes spill into the urine that forms in the tub........

Auditory short-term memory and the left superior temporal gyrus

by Greg Hickok in Talking Brains

Where is the "phonological store"? Ask the typical cognitive neuroscientist on the street and you will probably be pointed to the left inferior parietal lobe. But this is incorrect. First, the idea that there is a dedicated "phonological store" is probably incorrect. Second, the system that supports the temporary maintenance of phonological information isn't in the parietal lobe, but in the superior temporal region, i.e., the same general region that supports phonological processing during sp........

"The Tears of Strangers Are Only Water"

by David Berreby in Mind Matters

Empathy is a complicated emotion, even for mice. On seeing another in pain, a mouse will act as if it itself is also hurting—much more, though, if it knows the first mouse. Capuchin monkeys will help out another monkey, without any reward, but only if they're on friendly terms. People also feel less for those they dislike. But our species adds another layer of complication: We empathize more with people who are "like us" than with "them." This study, published this month, suggests that th........ Read more »

Defining edge effects by resource and sensitivity

by Jeremy in Voltage Gate

Considering the number of studies published describing habitat fragmentation and edge effects, why has the pattern and framework of these effects on ecosystems not been described? Ries and Sisk proposed a conceptual model in that paper that can account and predict, to some extent, the variability of an organism’s responses to different edges, usually indicated through an increase or decrease abundance at the edge, or no change at all....

Well, color me surprised

by Iddo Friedberg in Byte Size Biology

Nature is colorful. And the family of pigments that is mostly responsible for these colors are carotenoids. Carotenoids  make the apples red, the lemons yellow, the pumpkins oranges and, yes carrots, (from which their name is derived), orange.
Carotenoids also make flamingos and salmon pink, and color the puffin’s bill orange. But those animals cannot produce [...]... Read more »

Horizontal gene transfer from Zygo to pea aphid

by stajich in The Hyphal Tip

Another result from the analysis of the recently published genome of the pea aphid, Acyrthosiphon pisum. Nancy Moran and Tyler Jarvik present a study of the origin of the carotenoid production gene in pea aphid. Animals typically cannot make carotenoids so they sought to discover how this is possible. They find that it [...]... Read more »

MIT brain scanners Fedorenko et al present A new method for fMRI investigations of language: Defining ROIs functionally in individual subjects. Also on the list of authors is Nancy Kanwisher, one of the feared fMRI voodoo correlations posse.The paper describes a technique for mapping out the "language areas" of the brain in individual people, not for their own sake, but as a way of improving other fMRI studies of language. That's important because while everyone's brain is organized roughly th........ Read more »

Friday Weird Science: Rate Yourself, Please.

by Evil Monkey in Neurotopia

So the other day Sci is chatting with some friends, and mentions how INCREDIBLY AMUSED she always is by romance novels. This is for several reasons.

One (1): They have covers like this:

(Seriously, I crack up just looking at these. LOL!!! Ooooh. My new favorite. Look at that bulging codpiece. *snort* HAHAHAHAHAHA.)

Two (2): They are so predictable, particularly the period ones. Sci could write one RIGHT NOW:

Clinical assessment with a personal genome. It has happened.

by Mary in OpenHelix

So this morning I was listening to NPR as I usually do while waking up.  And then I had to actually pay attention.  They were doing personal genomics.  But not just theoretical personal genomics.  They were talking with Steve Quake, who has his personal genome in hand. The story is here: Genomes May One Day Be Medical Crystal Balls
And Steve had his sequence analyzed for medically deleterious mutations.  He took this to an MD friend, and together they went over the data.  It’s a pret........ Read more »

The mirror movement mutation

by Mo in Neurophilosophy

MIRROR movements are involuntary movements that mimic, and occur simultaneously with, voluntary movements on the opposite side of the body. The movements are known to occur because of a failure in communication between the two sides of the nervous system. They are thought to be normal during infancy and early childhood, but usually diminish with age and disappear altogether by the age of 10, following maturation of the corpus callosum, the massive bundle of nerve fibres connecting the left and r........
