Proton-beam therapy for cancer gets renewed attention

Ion Beam Applications SA, the Belgian company that leads the global market for huge proton-beam machines, is selling so many systems lately that it needs to boost its 1,200-strong workforce by 400 workers. It launched a big recruitment drive across the country this year, featuring radio and newspaper spots along with dozens of billboards and posters. [Registration required.]
