| Computerized, rolling DNA motors move molecular robotics to next level Posted: 07 Apr 2022 01:19 PM PDT Chemists integrated computer functions into rolling DNA-based motors, opening a new realm of possibilities for miniature, molecular robots. These DNA-based motors combine computational power with the ability to burn fuel and move in an intentional direction. |
| Nano particle trapped between mirrors works as a quantum sensor Posted: 07 Apr 2022 11:19 AM PDT Sensors are a pillar of the Internet of Things, providing the data to control all sorts of objects. Here, precision is essential, and this is where quantum technologies could make a difference. Researchers are now demonstrating how nanoparticles in tiny optical resonators can be transferred into quantum regime and used as high-precision sensors. |
| AI predicts if -- and when -- someone will have cardiac arrest Posted: 07 Apr 2022 11:19 AM PDT A new artificial intelligence-based approach can predict, significantly more accurately than a doctor, if and when a patient could die of cardiac arrest. The technology, built on raw images of patient's diseased hearts and patient backgrounds, stands to revolutionize clinical decision making and increase survival from sudden and lethal cardiac arrhythmias, one of medicine's deadliest and most puzzling conditions. |
| Deep-sea osmolyte finds applications in molecular machines Posted: 07 Apr 2022 07:10 AM PDT The molecule trimethylamine N-oxide (TMAO) can be used to reversibly modulate the rigidity of microtubules, a key component of molecular machines and molecular robots. |
| A mathematical shortcut for determining quantum information lifetimes Posted: 06 Apr 2022 02:20 PM PDT Scientists have derived an elegant equation that provides allows them to instantly calculate the quantum information lifetime for 12,000 different potential qubit materials. |
| The side effects of quantum error correction and how to cope with them Posted: 06 Apr 2022 01:04 PM PDT It is well established that quantum error correction can improve the performance of quantum sensors. But new theory work cautions that, unexpectedly, the approach can also give rise to inaccurate and misleading results -- and shows how to rectify these shortcomings. |
| Machine learning model could better measure baseball players' performance Posted: 06 Apr 2022 07:18 AM PDT Researchers have developed a machine learning model that could better measure baseball players' and teams' short- and long-term performance, compared to existing statistical analysis methods for the sport. Drawing on recent advances in natural language processing and computer vision, their approach would completely change, and could enhance, the way the state of a game and a player's impact on the game is measured. |
| Artificial intelligence may improve diabetes diagnosis, study shows Posted: 05 Apr 2022 07:28 AM PDT Using a fully-automated artificial intelligence (AI) deep learning model, researchers were able to identify early signs of type 2 diabetes on abdominal CT scans, according to a new study. |
