Bridging the 'valley of death' with philanthropic endowments
The so-called "Valley of Death" is a tragic place to land when attempting to translate exciting bench science to a bedside. But one expert says there's a potential way out of this academic wasteland: Universities should create philanthropic endowments, with the proceeds earmarked to helping scientists advance their innovations.
"By applying the same sort of innovative, out-of-the-box thinking to our financial and philanthropic approach as we have applied in our scientific labs, universities can take major steps in bringing drugs and other therapies to market — and improving people's lives," opines Roopa Ramamoorthi, who directs translational work at UCSF through its Catalyst Program and InVent Fund.
UCSF has already set up a philanthropy fund for innovation, and other academic centers are beginning to as well. Vanderbilt, Northwestern, and Harvard have all received large donations to set up new endowments to help with the translation of lab science into commercializable products — and more are sure to follow.

Diagnosing and treating colon cancer with ... yogurt?
What would you rather: a cool, refreshing smoothie, or a colonoscopy? Scientists are engineering bacteria meant to ultimately detect and deliver a treatment for colorectal polyps or cancer — and it's meant to be delivered in a rather palatable cup of yogurt. It's very early stage, but proof-of-concept work published in Science that shows these engineered bacteria can detect cancer in the guts of mice. Furthermore, the bugs, called Acinetobacter baylyi, turn on certain cellular circuitry when they come in contact with aberrant growths in the colon.
"You have something, in principle, that gives probiotics the ability to sense not only things floating around like proteins or small molecules, but they can look 'inside' mammalian cells at their genetic information, which is quite useful," said a California Institute of Technology engineer who is studying bacteria-driven diagnostics but wasn't involved in this work.
