| Designing healthy diets with computer analysis Posted: 20 Apr 2021 03:31 PM PDT A new mathematical model for the interaction of bacteria in the gut could help design new probiotics and specially tailored diets to prevent diseases. |
| Helpful, engineered 'living' machines in the future? Posted: 20 Apr 2021 03:31 PM PDT Engineered, autonomous machines combined with artificial intelligence have long been a staple of science fiction, and often in the role of villain like the Cylons in the 'Battlestar Galactica' reboot, creatures composed of biological and engineered materials. But what if these autonomous soft machines were ... helpful? |
| Combining light, superconductors could boost AI capabilities Posted: 20 Apr 2021 10:10 AM PDT As artificial intelligence has attracted interest, researchers are focused on understanding how the brain accomplishes cognition so they can construct systems with general intelligence comparable to humans' intelligence. Researchers propose an approach to AI that focuses on integrating photonic components with superconducting electronics; using light for communication and complex electronic circuits for computation could enable artificial cognitive systems of scale and functionality beyond what can be achieved with either light or electronics alone. |
| Boosting fiber optics communications with advanced quantum-enhanced receiver Posted: 20 Apr 2021 10:10 AM PDT Fiber optic technology is the holy grail of high-speed, long-distance telecommunications. Still, with the continuing exponential growth of internet traffic, researchers are warning of a capacity crunch. Researchers show how quantum-enhanced receivers could play a critical role in addressing this challenge. The scientists developed a method to enhance receivers based on quantum physics properties to dramatically increase network performance while significantly reducing the error bit rate and energy consumption. |
| Fixed network of smartphones provides earthquake early warning in Costa Rica Posted: 20 Apr 2021 10:10 AM PDT Earthquake early warnings can be delivered successfully using a small network of off-the-shelf smartphones attached to building baseboards, according to a study conducted in Costa Rica last year. |
| Forensics puzzle cracked via fluid mechanical principles Posted: 20 Apr 2021 09:15 AM PDT A real-life forensic puzzle inspired researchers to explore the physics involved, and in Physics of Fluids, they present theoretical results revealing an interaction of the incoming vortex ring of propellant muzzle gases with backward blood spatter. A detailed analytical theory of such turbulent self-similar vortex rings was given by this group in earlier work and is linked mathematically to the theory of quantum oscillators. |
| AI agent helps identify material properties faster Posted: 20 Apr 2021 09:15 AM PDT Artificial intelligence (AI) can analyze large amounts of data, such as those generated when analyzing the properties of potential new materials, faster than humans. However, such systems often tend to make definitive decisions even in the face of uncertainty; they overestimate themselves. An international research team has stopped AI from doing this: the researchers have refined an algorithm so that it works together with humans and supports decision-making processes. As a result, promising new materials can be identified more quickly. |
| Is social media use a potentially addictive behavior? Maybe not Posted: 20 Apr 2021 09:14 AM PDT Frequent use of social media may not amount to the same as addiction, according to new research. |
| Body mass index, age can affect your risk for neck pain Posted: 20 Apr 2021 09:14 AM PDT With roughly 80% of jobs being sedentary, often requiring several hours of sitting stooped in front of a computer screen, neck pain is a growing occupational hazard. Smartphones and other devices have also caused people to bend their necks for prolonged periods. But is bad posture solely to blame? |
| Materials advances are key to development of quantum hardware Posted: 19 Apr 2021 10:57 AM PDT A new article argues that the ability to move forward on developing useful quantum computers requires new major advances in materials science, engineering and fabrication. The authors call for new approaches from broad areas of science and engineering. |
