| Black hole size revealed by its eating pattern Posted: 12 Aug 2021 11:50 AM PDT The feeding patterns of black holes offer insight into their size, researchers report. A new study revealed that the flickering in the brightness observed in actively feeding supermassive black holes is related to their mass. |
| New study shows the potential of DNA-based data-structures systems Posted: 12 Aug 2021 09:31 AM PDT Engineers have created new dynamic DNA data structures able to store and recall information in an ordered way from DNA molecules. They also analyzed how these structures are able to be interfaced with external nucleic acid computing circuits. |
| NASA spacecraft provides insight into asteroid Bennu's future orbit Posted: 12 Aug 2021 05:21 AM PDT Along with collecting a sample from the Bennu's surface, the spacecraft provided precision data to better predict the near-Earth object's orbit around the Sun. |
| Engineers uncover the secrets of fish fins Posted: 11 Aug 2021 01:28 PM PDT A new study has uncovered the engineering secrets behind what makes fish fins so strong yet flexible. The research could one day lead to new designs for robotic surgical tools or even airplane wings that change their shape with the push of a button. |
| Scientists develop chain mail fabric that can stiffen on demand Posted: 11 Aug 2021 10:15 AM PDT Scientists have developed a new type of 'chain mail' fabric that is flexible like cloth but can stiffen on demand. The lightweight fabric is 3D-printed from nylon plastic polymers and comprises hollow octahedrons (a shape with eight equal triangular faces) that interlock with each other. When encased in a plastic envelope and vacuum-packed, it becomes 25 times more rigid and can hold up over 50 times its own weight. |
