NASA to launch mini lab, test for cancer and disease in space

DNP Microflow

It's hard to find a good specialist on earth, let alone when you're floating 240 miles above it. That's why NASA will test the Microflow, a breadbox-sized device that instantly detects cancer and infectious diseases, and can even sense the presence of rotten food. The Canadian-made device is a "flow cytometer," which works by analyzing microparticles in blood or other fluids and replaces hospital versions weighing hundreds of pounds. Here on Earth, the device could let people in remote communities be tested more quickly for disease, or permit on-site testing of food quality, for instance. It will be particularly advantageous in space, however, where Canadian astronaut Chris Hadfield will test it during his six-month ISS mission, allowing crew to monitor, diagnose and treat themselves without outside help. Now, if we could just get it down to a hand size, and use some kind of radio waves instead -- oh wait, that's not until Stardate -105352.

MIT engineers develop glucose-based fuel cell to be used in neural implants

MIT engineers develop glucose-based fuel cell to be used in neural implants

We've seen fuel cells used in a variety of gadgets -- from cars to portable chargers -- and while medical devices aren't exactly at the top of the list, they're yet another application for these mini power sources. MIT engineers are turning to sugar to make fuel cells for powering brain implants. The scientists developed cells that use platinum to strip electrons from glucose molecules found in a patient's cerebrospinal fluid to create a small electric current. The fuel cells are fabricated on a silicon chip so they can interface with other circuits in a brain implant. The prototype can generate up to hundreds of micro watts, which is enough to power neural implants used to help paralyzed patients move their limbs. Mind you, this technology is years away from making it to market. The next step will be proving that the devices work in animals, which reminds us of one Ricky the rat, who survived a biofuel cell implant back in 2010.
