Physician burnout and job dissatisfaction are concerning as physicians in the United States have more patients to see in less time with fewer resources. Physician burnout is associated with job absenteeism, leaving the profession altogether, poor quality of care, and medical errors. Now, a recent study published in the Journal of the American Medical Association [...]... Read more »

Michael Ash BSc(Hons) DO, ND, Dip ION explores the idea that drinking sparkling water has a direct health benefit for the drinker, if not for the environment.
In this case fizzy drink consumers are directed towards a specific water drink rather than some of the more challenging sugar laden carbonated offerings. So if compelled to drink [...]... Read more »

Two of the frequent aims of career coaching or counselling are to empower clients and to help them develop amibtious personal goals. Nothing could possibly be wrong with that, you might think.

Really need to take care of the long lineup of overdue Mystery Micrographs. And clean up a bit of this huge drafts pile that has accumulated lately. Because I'm lazy, let's do Spironucleus first, from MM17. It goes well with laziness as not very much is known about it, which means there isn't too much to write about it.

In the last post, we looked at a piece of research on how easy it is to clean up the scientific literature in the wake of retractions or corrections prompted by researcher misconduct in published articles. Not surprisingly, in the comments on that post there was some speculation about what prompts researchers to commit scientific misconduct in the first place.

The fail whale comes to rest; the decomposing body of a gray whale is host to a diverse array of scavengers and other deep sea organisms. From Goffredi et al., 2004.
In the deep sea, no carcass goes to waste. Platoons of crabs, fish, and other scavengers make short work of most of the bodies which come to rest on the sea bottom, but every now and then the carrion-eaters are presented with a rotting bonanza; a whale fall. Muscle, viscera, blubber, and bone; it all gets broken down, but it t........ Read more »

In Polydnaviruses: Nature’s GMOs, I wrote about how wasps use viruses to disable the immune defenses of their hosts. Braconid and ichneumonid wasps use a system that genetically modifies their hosts in order to shut their immune systems down.
So how does this all work?
A good system to use to describe how polydnavirus proteins work is [...]... Read more »
