Technology
Scientists at MIT have developed a microscopic coating process that can release drugs at the command of an electrical signal. The coating, a thin film, is made of a therapeutic and an electrically-active compound called Prussian blue that can be applied to medical devices like stents or to polymers that can be injected into the body. By applying an electrical field to the device the coating of Prussian blue dissolves and the drug is released. Story [1]
Stem Cell Research
In order to add some leverage to its $3 billion program to support stem cell research in California, the state stem cell institute announced that 12 applicants for funding offered to put up $495 million of their own money in order to win up to $262 million pooled for grants. That collective contribution, says the institute, will boost sending on new laboratories by $750 million. The most ambitious offer: Stanford's, where university officials pledged $150 million in order to gain state backing. Report [2]
Human embryonic stem cells produce a protein that can be used to contain breast and skin cancers, according to researchers at Northwestern University. Report [3]
Rejecting arguments that patents held by the Wisconsin Alumni Research Foundation are unfairly hindering research in the field, an official with the patent office ruled that one of the three patents will stand. Two others remain under appeal. Lawyers urging a repeal of the patents, though, say they've only just begun to fight. Story [4]
