When I’m working with someone who has chronic pain, from the outset I’m pretty straight-up that the treatments I offer don’t directly affect pain intensity. It’s not my focus, and very often after the first session, I don’t even discuss pain – I’m more interested in what the person is doing! And for this focus, … Read more... Read more »

I haven't worked very much with bacteria that infect humans. Most of my lab work has been done in the fields of either synthetic biology (which works with model organisms) or antibiotic production, which works on soil bacteria that produce the antibiotics. Human bacterial parasites therefore hold the fascination of the slightly exotic, not least because they sometimes do things like this:Figure from"Molecular Biology of the Cell, Fourth Edition"by Alberts et al.I've written before about some of ........

Surgery is often the only solution to prevent disabilities and death from conditions resulting from pregnancy related complications, surgical conditions (example acute abdomen), infections, traffic accidents, falls, burns, disasters, domestic violence, and congenital defects. Until recently, surgery was neglected as a developing country public health issue. Health officials, especially in the World Health organization and [...]... Read more »

It is important for HIV infected patients to take their drugs regularly. Interruptions in treatment lead to viral strains that are resistant to the cheapest medications, and to higher rates of illness and death. Unfortunately, many AIDS patients do not come for their antiretroviral medications. Such patients are labelled as “lost to follow-up.” During the [...]... Read more »

Bones of a giant manabou stork have been unearthed recently from the Pleistocene of Liang Bua cave in Flores, Indonesia.

"Costly punishment" is the term used to describe an interesting phenomenon in which people will punish wrongdoers even if it brings a cost to themselves. For example, you could imagine a situation where a vigilante attempts to beat up a criminal - risky, if the criminal gets the upper hand. It's an understandable reaction if you are going to have to deal with the individual again.
Yet lab studies show that people will punish misbehaviour even if all the transactions are anonymous and "single-sh........ Read more »
I’m just reading a paper on the response properties of monoamine neurons, and it starts out with a few points of consideration for electrophysiological recording of neurons in vivo. I thought I’d relay them here.
The evidence that you are recording from a given type of neuron (dopaminergic, serotinergic etc.) is almost always indirect. It is usually . . . → Read More... Read more »

Thinking about fitness landscapes can stimulate detailed discussion and consideration of the meanings and limitations of such metaphors, and my introductory comments did just that. Most notably, Joe Felsenstein pointed us to the various ways these depictions can be employed, and urged everyone to use caution in interpreting them.All too true, but the goal here is modest: I want to discuss the interesting questions that arise when considering the relationship between genotypes and phenotypes, i.e........

In a previous post, I looked at the varieties of traumatic experiences and their risk of inducing PTSD in men and women. Another aspect of the epidemiology of PTSD is a more basic look at the overall prevalence of exposure to individual traumatic experiences. There has been significant discussion and research to define the trauma severity required to increase risk of a PTSD response. Early studies tended to have a lower threshold for severity. They included not only a pers........ Read more »

I've been ill, and pressing deadlines for book chapters and other projects have kept me busy. An inability to post stuff on Tet Zoo always frustrates me, as there's just so much Tet Zoo-relevant stuff to get through. And, on that note: I must have said on many occasions that there are whole tetrapod groups, consisting of hundreds or even thousands of species, that I've either never mentioned at all, or have only touched on in passing. I aim to get through as many as I can while the going's goo........ Read more »

Pont St. Esprit is a small town in southern France.

In this first phase, the symptoms were generalized, and consisted in a depressive state with anguish and slight agitation.After some hours the symptoms became more clearly d........ Read more »
As you know, my post-doc in Uppsala ended. It was a good time, and it was great collaborating on Bioclipse with Ola, Jonathan, Arvid, and Carl. I would have loved tighter integration with the work of Maris and Martin, but that was limited to one joined paper (in press). I thank Professors Jarl Wikberg and Eva Brittebo for allowing me to continue my research at their department, and hope this is not the end of the collaboration yet.

Does carboxyhemoglobin vary that much that a few seconds later, the HbCO is wildly different?

PTSD represents a pathological response to a serious trauma. The evolution of the diagnostic criteria for PTSD has included a broadening of the types of trauma exposures felt sufficient to trigger PTSD. The original criteria included combat, concentration camp confinement, natural disaster, rape or physical assault. The current DSM-IV criteria for trauma require that "the person experienced, witnessed or was confronted with an event(s) that involved actual or threatened death or seri........ Read more »
