| Lighting up biology from within Posted: 11 May 2021 09:36 AM PDT A biochemical reaction between an enzyme called luciferase and oxygen causes fireflies to glow and is considered one of the most well-known examples of bioluminescence in nature. Now, an international team of researchers are working to harness the power of bioluminescence in a low-cost, noninvasive portable medical imaging device that could one day be applied to many uses in biomedical research, translational medicine and clinical diagnoses. |
| Electromagnetic levitation whips nanomaterials into shape Posted: 11 May 2021 09:36 AM PDT To deliver reliable mechanical and electric properties, nanomaterials must have consistent, predictable shapes and surfaces, as well as scalable production techniques. Engineers are solving this problem by vaporizing metals within a magnetic field to direct the reassembly of metal atoms into predictable shapes. |
| Discovering candidate for reflex network of walking cats: Understanding animals with robots Posted: 11 May 2021 09:35 AM PDT A group of researchers developed a quadruped robot platform that can reproduce the neuromuscular dynamics of animals, discovering that a steady gait and experimental behaviors of walking cats emerged from the reflex circuit in walking experiments on this robot. |
| Quantum mechanics paves the way for more stable organic solar cells Posted: 11 May 2021 09:35 AM PDT Quantum mechanics can be used to create more stable and more easily produced organic solar cells. |
| In 'minibrains,' hindering key enzyme by different amounts has opposite growth effects Posted: 11 May 2021 05:12 AM PDT Surprising findings can help improve organoid cultures, explain role of GSK3-beta in brain development. |
| Stabilizer residue in inks found to inhibit conductivity in 3D printed electronic Posted: 11 May 2021 05:12 AM PDT Very thin layers of organic stabilizer residue in metal nanoparticle (MNP) inks are behind a loss of conductivity in 3D printed materials and electronic devices, according to the findings of a new study. |
| New genetic copycatchers detect efficient and precise CRISPR editing in a living organism Posted: 11 May 2021 05:11 AM PDT Scientists have developed a novel genetic sensor called a 'CopyCatcher,' which capitalizes on CRISPR-based gene drive technology, to detect instances in which a genetic element is copied precisely from one chromosome to another throughout cells in the body of a fruit fly. Next-generation CopyCatcher systems have the potential to measure how often such perfect copying might take place in different cells of the human body. |
| Researchers develop magnetic thin film for spin-thermoelectric energy conversion Posted: 11 May 2021 05:11 AM PDT Engineers have proposed a satellite-aided drought monitoring method that can adequately represent the complex drought conditions into a single integrated drought index. |
| The Aqueduct of Constantinople: Managing the longest water channel of the ancient world Posted: 11 May 2021 05:11 AM PDT Aqueducts are very impressive examples of the art of construction in the Roman Empire. Even today, they still provide us with new insights into aesthetic, practical, and technical aspects of construction and use. Scientists investigated the longest aqueduct of the time, the 426-kilometer-long Aqueduct of Valens supplying Constantinople, and revealed new insights into how this structure was maintained back in time. |
| Low temperature physics gives insight into turbulence Posted: 11 May 2021 05:11 AM PDT A novel technique for studying vortices in quantum fluids has been developed by physicists. Turbulence in quantum systems, for example in superfluid helium 4, takes place on microscopic scales, and so far scientists have not had tools with sufficient precision to probe eddies this small. But now the team, working at temperature of a few thousandths of a degree above absolute zero, has harnessed nanoscience to allow the detection of single quantum vortices. |
