Calico, Google's ($GOOG) semi-secretive biotech venture, stepped into the spotlight with a high-dollar collaboration this week, and now the California startup is mounting a big recruitment effort, according to a report. As Ron Leuty reports in the Silicon Valley Business Journal, Calico is looking to hire as many as 150 workers, looking at some already employed by Genentech--the company from which it poached its CEO and head of R&D. Calico, which is focused on R&D related to aging, recently signed a deal with AbbVie ($ABBV) to team up on discovery and development, with the two agreeing to spend as much as $1.5 billion on the collaboration.
