Artificial tongue distinguishes 18 different types of canned tomato
Taste tests are fun -- unless you're in Italy, in which case they're drawn-out and rancorous. That's why scientists in Milan are trying to remove humans from the equation, by using nuclear magnetic resonance (NMR) spectroscopy to reveal objective "metabolomic fingerprints" for different foodstuffs instead. In their latest experiment, NMR succeeded in predicting how human testers would judge 18 different canned tomato products, including sensory descriptors such as bitterness, saltiness, "redness" and density. Like Caesar always said, technology that knows a good ragu is technology we can trust.
$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.
