First, there was the great hope of induced pluripotent stem cells (iPSCs), and then there was the inevitable letdown. When the announcement came, in 2006, that simple adult skin cells could be reprogrammed – reverted back to an embryonic stem cell state by the addition of just four genes – it seemed like an almost…

Getting into the Fray

“The public, blog-fueled controversy over the utilization of arsenate instead of phosphate in bacteria was, in the end, a demonstration of what is truly right with scientific quests,” says Prof. Dan Tawfik. “The original findings (that certain bacteria can use arsenate instead of phosphate) may have been overhyped. The research itself may have been underwhelming.…

A somewhat accidental discovery and random meetings between proteins in a cell: These are the subjects of two new online articles. Each, it its way, involves a technological advance that will, in turn, lead to further scientific discovery. The first involves a partnership between a physics group and a cancer-research group. Among other things, such…
