So I’ve been working in medical laboratories for a few years, and the logistics of the handling and storing biological samples is always pretty intensive. Companies often have to keep blood at certain temperatures, process them within certain timeframes, and devise a workflow that separates blood components and ensures that all the necessary tests can be done off of the provided volumes. To sum it up: tons of freezers, refrigerators, centrifuges and electricity bills! So when this equimpment from ThermoFisher popped up on my LinkedIn feed, I was pretty excited to research it!
After seeing this hilarious video on Metafilter, I had to look more into these magnetotactic bacteria. I’d never heard of these, and from the video, they look like the bacteria are able to be steered using a magnetic field. Here’s what I’m finding so far. (more…)
That’s right, this month’s IEEE Spectrum has lots of sweaty people, and details about how we can use sweat to measure the physical state of the human body. It also brings out a really interesting piece of tech I’d never heard of, called Iontophoresis. This process uses an electrically charged pad on the skin, runs a low current through it, and causes the skin to sweat, which will draw the medication down into the dermis. Here’s a PDF of an excellent article by the Physical Therapy Journal that details the methods and challenges of using this particular technology. So they used these sweat-inducing patches to keep that lovely sweat a’flowing. From that, they went on to measure the electrolytes and other chemicals found in the sweat.
There’s also a great article on turning car bodies “see-through” to be able to see blind spots. Even though it takes quite a while for auto manufacturers to get new tech integrated into their vehicles, maybe someday we’ll get them. At least before the cars drive themselves, right?
