| Facial recognition ID with a twist: Smiles, winks and other facial movements for access Posted: 18 Mar 2021 05:55 AM PDT Concurrent Two-Factor Identity Verification requires both one's facial identity and a specific facial motion to gain access. To set it up, a user faces a camera and records a short 1-2 second video of either a unique facial motion or a lip movement from reading a secret phrase. The video is then input into the device, which extracts facial features and the features of the facial motion, storing them for later ID verification. |
| New bioink brings 3D-printing of human organs closer to reality Posted: 17 Mar 2021 08:17 AM PDT Researchers have designed a new bioink which allows small human-sized airways to be 3D-bioprinted with the help of patient cells for the first time. The 3D-printed constructs are biocompatible and support new blood vessel growth into the transplanted material. This is an important first step towards 3D-printing organs. |

| How do birds breathe better? Researchers' discovery will throw you for a loop Posted: 16 Mar 2021 08:22 AM PDT Researchers have discovered that birds breathe with greater efficiency than humans due to the structure of their lungs -- looped airways that facilitate air flows that go in one direction. |
