6:32 PM | Nontraditional Animal Models—The Ground Squirrel
We still talk about guinea pigs as experimental subjects yet you'd have a hard time finding one in a modern research laboratory. Guinea pigs were first used in biomedical research in the late 19th century, playing a major role in establishing the germ theory, identifying pathogens, linking vitamin C insufficiency to scurvy, and modeling diabetes and pre-eclampsia. The guinea pig metaphor lives on but today, mice, rats, fruit flies, nematodes, and zebrafish dominate as model animals. But there […]

1:54 PM | No link between STAP cells and acid reflux, except for paper’s authors
> If you’ve stayed current with the STAP cell fiasco you know it’s been a wild ride. STAP cells, or Stimulus-Triggered Acquisition of Pluripotency cells, caught the imagination of many in late January through their sheer simplicity: You hit cells with a shock of acidic conditions, and they become pluripotent. That’s it. No Yamanaka factors...Read more

It isn't your imagination. The recent ups and downs in biomedical research funding have made for turbulent times in academic laboratories across the US. Jennifer Couzin-Frankel points out in her overview article to an imaginatively reported "News Focus" section last week in Science on the work force and funding crisis in biomedical science that the NIH budget doubled between 1998 and 2003 from around $14 billion to $27 billion but remained essentially flat for the next five years.

3:42 PM | Lusty Worms Pass Love Notes through Tiny Bubbles
Nearly every cell in your body is releasing microscopic bubbles that contain tiny messages to other cells in your body. The bubbles are so small that if a cell were the size of the Empire State Building, the vesicles would be the size of teenage couriers, running to deliver messages to neighboring buildings in the organism of Manhattan. But now there's evidence that at least in worms, these little bubbles, called extracellular vesicles (ECVs), can leave the cells of the Manhattan Island worm to […]
