Intestinal stem cells: no longer immortal but ever so clever....

To maintain tissue homeostasis, stem cells must balance self-renewal with differentiation. In some stem cell lineages this process is 'hard-wired' by the asymmetric partitioning of determinants at division, such that one stem cell daughter always remains pluripotent and other differentiates. But in a dynamic tissue like the intestinal epithelium, which might need to repair itself following an i...

Have you ever seen a 21-mmol/L serum K+ concentration?

When the sample was reanalyzed by direct ion selective electrode (ISE) method, potassium was 20.3 mmol/L and calcium was below the lower limit of quantification. Hyperkalemia can be seen with hemolysis, leukocytosis, fist clenching during venipuncture, or analytical errors (1, 2). In these situations, hyperkalemia of this magnitude would not be expected, and calcium should be normal. In our cas...

O One Has Ever Seen a Planet outside Our Solar System. Other Earths

outside our solar system. But in November of last year two astronomers saw the next best thing: its shadow. David Charbonneau, a graduate student at Harvard University, was analyzing the brightness of the sunlike star HD 209458 using data taken earlier, when he had been working with one of us (Brown). At nearly the same time, Tennessee State University astronomer Greg Henry was independently ob...
