Toshiba, in partnership with the National Cancer Center Research Institute and Tokyo Medical University will conduct a trial of the machine next year. Development of this chip follows on the heels of research that finds testing for microRNA in bloodwork has the potential to detect cancers in earlier stages, and in some cases like for bowel cancer, with a much less invasive testing procedure. Their work builds on that of Toray Industries, who announced earlier this year that they had made a cancer-detection chip based on microRNA accumulation that is 95% accurate. The machine works by assessing the different types of microRNA that show up in the sample drop, and studying their concentrations. So, how does it work? Cancer cells secrete certain types of microRNA into the bloodstream that healthy cells don’t. Image source: Toshiba Corporate Reserach Center The only catch is that the machine can’t pinpoint which cancer exactly, it only knows if microRNA one or more of the 13 came up. But this machine can screen for all three of these - great news for early detection of these ravaging cancers - as well as breast, prostate, gastric, colon, liver, biliary tract, bladder, lung, brain, and sarcoma. Some of the cancers the machine can test for have been previously difficult to detect, like ovarian, pancreatic, and esophageal cancer. Ideally, this machine will do everything that current blood cancer detection equipment does, just better, faster, and with fewer resources. Most importantly, they are aiming to do this entire battery of tests for about $180. What’s more impressive is that it can do this under two hours, as opposed to days or weeks depending on laboratory backlog. Toshiba claims that the machine can detect 13 types of cancer from a single drop of blood with 99% accuracy. But this small machine can do some powerful tricks. The machine is about the size of a small office copier, and it looks like one, too. But Toshiba has created a cancer-detecting machine that sounds like something straight out of science fiction. Existing methods of screening for cancer usually involve taking a whole lot of blood and running tests that cost thousands of dollars. Continue reading “What’s An Exciton?” → Posted in Hackaday Columns, News, Science, Slider Tagged bosun, exciton, semiconductor, subatomicĬan you imagine a near future where your family doctor can effectively prick your finger and test you for a dozen or so types of cancer? Currently, cancer detection is a time-consuming and expensive process. That is, the state itself is neutral, but also contains energy. The reason scientists are interested in the beast is that it can transport energy without transporting net electric charge. You are probably familiar with the idea of an electron hole from semiconductor physics. An exciton is a bound state of an electron and an electron hole and is technically a boson. It actually sounds like a subatomic particle, but it is a little more complicated than that. But recently there has been a lot of buzz about excitons and even some transistor circuits demonstrated that use them. If you are young enough, you see others you probably heard about, too, like quarks and gluons. They want the resistor and capacitor there to protect the NeoPixels.If you read the scientific literature, you see the familiar subatomic particles you learned about in school: protons, neutrons, and electrons. There are instructions for using NeoPixels on Adafruit's website. To get the lights looking awesome, I painted some silver (just as opaque as black, but more reflective) paint in strategic places inside the white cover. Otherwise the light leaks out the side.īe sure to ream out and tap the holes for the button straight, or it won't look nice. The Portal cube is one that I downloaded from here or thingiverse. it's a hollow one, and I filled it with lead, then glued it shut.Ī quick video of it working can be found here: of course they look better with finer layers. I ended up modeling it myself, using some 3D files that I found online someplace, that were unprintable. they are similar to many other wireless light switches so should be adaptable to other countries. If you want to switch lights on and off, I have used a transmitter unit that works with Klikaan Klikuit units. Have a look on Adafruit's website for instructions on programming a trinket with Arduino. Just a bit fidely to get working if you have not used one before. My first version used a barebones Arduino Uno on a proto-board, but the Trinket is much easier. So I decided to build a working 1500 Megawatt Aperture Science Heavy Duty Super-Colliding Super Button to switch the lights that shine on my movie collection.
