An exercise machine that helps stroke victims walk. An advanced technology for assessing the progress of prostate cancer. A faster process for making neural stem cells to investigate new treatments for injury and disease. A cheaper, more beautiful LED light bulb. A game to teach meditation.
These projects, and a dozen more, are beneficiaries of the first round of awards by the University of Wisconsin-Madison’s Discovery to Product, or D2P, program, which began operating in March. The 17 grants announced this week will support innovations in many fields of research at the university, from food engineering and medicine to stem

The great promise of induced pluripotent stem cells is that the all-purpose cells seem capable of performing all the same tricks as embryonic stem cells, but without the controversy.
However, a new study published this week (Feb. 15) in the Proceedings of the National Academy of Sciences comparing the ability of induced cells and embryonic cells to morph into the cells of the brain has found that induced cells — even those free of the genetic factors used to program their all-purpose qualities — differentiate less efficiently and faithfully than their embryonic counterparts.
The finding that induced cells are
