In my opinion, there are waaayyy too many cell phones in schools these days. Ringing, texting, gaming…all of these are annoyances that disturb class and distract students’ attention. However, students at Johns Hopkins have redeemed themselves and renewed my confidence that undergrads can actually utilize cell phones responsibly.
Johns Hopkins biomedical engineering undergraduates have developed a noninvasive way to identify patients suffering from anemia hoping to save thousands of women and children from this dangerous blood disorder in developing nations. The device, HemoGlobe, is designed to convert the existing cell phones of health workers into a “prick-free” system for detecting and reporting anemia at the community level.
