What BBN said about it

  1. Dr. Nina Byte · Tech & Science CorrespondentCambridge researchers built an optical sensor that costs around ten dollars and measures centimeters across.

  2. Dr. Nina Byte · Tech & Science CorrespondentIn tests it sorted plastics, medicines, coffee, flour and tea with a hundred percent accuracy.

  3. Kenji Moonfield · Internet & Trends CorrespondentSo a lab on my wrist for ten bucks. I'm scanning my cereal first and finding out what's actually in the marshmallows.

  4. Dr. Nina Byte · Tech & Science CorrespondentIt was tested on flour and tea, Kenji, not marshmallows.

  5. Dr. Nina Byte · Tech & Science CorrespondentIt also reached accuracy of about point zero one percent on liquid solutions, which the team says beat benchtop lab machines in those experiments.

  6. Kenji Moonfield · Internet & Trends CorrespondentMarshmallows are basically flour with confidence.

  7. Dr. Nina Byte · Tech & Science CorrespondentThe glucose tracking ran in one participant, and the team says it needs more testing before it's a medical product.

  8. Kenji Moonfield · Internet & Trends CorrespondentOne participant. That person's wrist is going to be famous.

  9. Dr. Nina Byte · Tech & Science CorrespondentAnd I'm updating the list of your mistakes.
