According to Mormon author and fruit grower "Dr" Robert O. Young, pretty much all diseases are caused by our bodies being too acidic. By adopting an "alkaline lifestyle" to raise your internal pH (lower pH being more acidic), you'll find that
if you maintain the saliva and the urine pH, ideally at 7.2 or above, you will never get sick. That’s right you will NEVER get sick!
Wow. Important components of the alkaline lifestyle include eating plenty of the right sort of fruits and vegetables, id........ Read more »

While I was trying to come up with something quick to blog about, got a couple updates in Google Reader from J. Eukaryotic Microbiol, among them a paper on... trypanosomatids living in coconut tree phloem! Somehow, you don't typically think of plants being invaded by motile, flagellate things, but on a second thought: why not? The phloem is a vessel, and while perhaps there's no need to run away from macrophages or anything, there's no particular harm in retaining the ability to swim around. Esp........ Read more »

The knee of an athlete is often a diagnostic dilemma. The knee obtains important biomechanical function and is supported by an array of ligaments and muscles. For these reasons it can be difficult to pinpoint the specific structure which is injured.

Therapists should bury their modesty and adorn the walls with their well-earned certificates and diplomas. That's according to Ann Devlin and colleagues who asked 227 undergrads to look for one minute at a photo of a clinician's office, furnished in a modern, minimalist style, and to give their impression of the therapist who worked there. All the photos were taken from the perspective of the client's chair, but some students were shown a version with bare walls and no family photos on the desk,........ Read more »

They are usually built up from hydroxyl-acyl CoA derivatives through a range of different pathways in different microorganisms. As they are b........ Read more »

One of the common misconceptions about biological evolution is that the process pushes organisms towards a pinnacle of perfection in which the ‘most evolved species’ maintain dominance over ‘less evolved’ or ‘lower organisms.’ Often closely associated with this mistaken belief is the erroneous idea that, by virtue of braininess, our own species – Homo sapiens - currently holds sovereignty over evolution’s hypothetical pinnacle. These egocentric a........ Read more »

Some nagging uncertainties remain on progress in stem cell medicine - and especially progress in reprogramming easily obtained somatic cells into patient-specific pluripotent stem cells. These uncertainties will be answered and addressed in the years ahead, but this one springs to mind today: it is possible that cells from older people may be altered or damaged in ways that prevent their effective use as-is in the sort of autologous stem cell therapies presently envisaged. That would be a setbac........ Read more »
