MIT scientists made a biomonitoring pill that patients can swallow to collect their pulse, breathing rate and internal temperature. And musicians have a new option in the form of the tiny Motus instrument, which recognizes shaking and twirling to create music out of movement.
Handheld millimeter / microwave camera to see through walls, your underpants (video)
You know those scanners that peep your naughty bits at the airport? Well, a team of researchers have been working on a handheld camera that sports the same technology, and while they're touting its future impact on stuff like cancer detection and aerospace engineering, we can't help but squirm thinking about its Peeping-Tom potential. The camera currently takes 30 images per second by transmitting millimeter and microwaves to a "collector" on the other side of a subject, and then sends them to a laptop for real-time inspection. Aside from being able to see straight through your BVDs, it can also be used to detect defects in spacecraft insulation, find termites lurking in the walls of your apartment, and help in the diagnosis of skin disease. The camera's creators are working on a smaller, one-sided version of the device that could have mass-market appeal -- we just hope this thing stays in R&D long enough for us to get our bikini bodies back. Check out a video of its G-rated abilities after the break.
$200 'Mini' NMR detects cancer faster and cheaper than full biopsies
Detecting cancer could be on the verge of getting a whole lot cheaper -- and better. Researchers at Harvard and MIT have come up with a device that, using a needle to get a tissue sample, has achieve 96 percent accuracy despite having a cost to produce of just $200. It's called a mini NMR (for nuclear magnet resonance) and also gives results in under an hour, giving the good or bad news on a smartphone display. The cost, simplicity, and portability could make it much easier for cancer to be caught and diagnosed early, but naturally it still has a good bit of testing left before it'll be ready for prime time.
New high-res imaging could make biopsies obsolete, doctors still cutting up in meantime
So maybe a true-to-life Innerspace is still a few years off, but a professor at the University of Rochester has developed a way to take high-resolution 3D images under the skin's surface, potentially eliminating the need for biopsies in cancer detection. Professor Jannick Rolland created a prototype that uses a liquid lens, in which a droplet of water replaces the standard glass lens, in conjunction with near-infrared light, to take thousands of pictures at varying depths. Those images are then combined to create clear, 3D renderings of what lies up to one millimeter below your epidermis. The method has already been tested on livings beings, but is likely a long way from making it to your doctor's office, which means it's off to the guillotine for that Pangaea-shaped mole you've been picking at.
NASA's new e-nose can detect scent of cancerous brain cells
NASA's recently developed electronic nose, intended for air quality monitoring on Space Shuttle Endeavour and later the International Space Station, has a rather fortunate and unintended secondary role. In addition to being able to detect contaminants within about one to 10,000 parts per million, scientists have discovered it can also sniff out the difference in odor between normal and cancerous brain cells -- not a new use for e-noses, but certainly one that helps to advance the field. Groups such the as Brain Mapping Foundation, City of Hope Cancer Center, and Jet Propulsion Laboratory have been testing the technology and hope it one day leads to a new understanding of cancer development. We'd also wager it can accurately detect what cologne or perfume you're wearing, another unintended side effect and probably not as fun of a party trick as it seems.
