| 'Human-like' brain helps robot out of a maze Posted: 10 Dec 2021 11:07 AM PST A maze is a popular device among psychologists to assess the learning capacity of mice or rats. But how about robots? Can they learn to successfully navigate the twists and turns of a labyrinth? Now, researchers have demonstrated they can. Their robot bases its decisions on the very system humans use to think and act: the brain. The study paves the way to exciting new applications of neuromorphic devices in health and beyond. |
| Development of a versatile, accurate AI prediction technique even with a small number of experiments Posted: 10 Dec 2021 07:31 AM PST Researchers have used the chemical materials open platform framework to develop an AI technique capable of increasing the accuracy of machine learning-based predictions of material properties (e.g., strength, brittleness) through efficient use of material structural data obtained from only a small number of experiments. This technique may expedite the development of various materials, including polymers. |
| Resolving the puzzles of graphene superconductivity Posted: 10 Dec 2021 07:31 AM PST Since superconductivity in three-layered graphene was discovered in September, the physics community has been left puzzled. Now, three months later, physicists can successfully explain the results by drawing from a theory of unconventional superconductivity. |
| Infant stars identified at the center of our galaxy Posted: 10 Dec 2021 07:31 AM PST A cosmic object originally classified as a gas and dust cloud actually consists of three stars and could resolve a controversy among astronomers. |
| The tetra-neutron – experiment finds evidence for a long-sought particle comprising four neutrons Posted: 10 Dec 2021 07:31 AM PST While all atomic nuclei except hydrogen are composed of protons and neutrons, physicists have been searching for a particle consisting of two, three or four neutrons for over half a century. Experiments by a team of physicists now indicate that a particle comprising four bound neutrons may well exist. |
| AI models microprocessor performance in real-time Posted: 10 Dec 2021 07:31 AM PST Computer engineers have developed a new AI method for accurately predicting the power consumption of any type of computer processor more than a trillion times per second while barely using any computational power itself. Dubbed APOLLO, the technique has been validated on real-world, high-performance microprocessors and could help improve the efficiency and inform the development of new microprocessors. |
| Innovative silicon nanochip can reprogram biological tissue in living body Posted: 10 Dec 2021 07:30 AM PST A silicon device that can change skin tissue into blood vessels and nerve cells has advanced from prototype to standardized fabrication, meaning it can now be made in a consistent, reproducible way. |
| Doctoral student finds alternative cell option for organs-on-chips Posted: 10 Dec 2021 07:30 AM PST Organ-on-a-chip technology has provided a push to discover new drugs for a variety of rare and ignored diseases for which current models either don't exist or lack precision. In particular, these platforms can include the cells of a patient, resulting in patient-specific discovery. |
| New biosensors shine a light on CRISPR gene editing Posted: 10 Dec 2021 07:29 AM PST Detecting the activity of CRISPR gene editing tools in organisms with the naked eye and an ultraviolet flashlight is now possible using new technology. |
| A step toward 'living biotherapeutics' Posted: 10 Dec 2021 06:30 AM PST Chemical engineers have developed a protective coating that helps anaerobic microbes survive the manufacturing process, making it potentially easier to use them to treat gastrointestinal disease. |
| Development of a high-energy-resolution, LaB6 nanowire-based field emission gun Posted: 10 Dec 2021 06:30 AM PST Engineers have developed a lanthanum hexaboride (LaB6) nanowire-based field emission gun that is installable on an aberration-corrected transmission electron microscope (TEM). This combined unit is able to perform atomic resolution observation at an energy resolution of 0.2 eV -- the highest resolution ever recorded for non-monochromatic electron guns -- with a high current stability of 0.4%. |
| Atom laser creates reflective patterns similar to light Posted: 10 Dec 2021 06:30 AM PST Cooled to almost absolute zero, atoms not only move in waves like light but also can be focused into shapes called caustics, similar to the reflecting or refracting patterns light makes on the bottom of a swimming pool or through a curved wine glass. In experiments, scientists have developed a technique to see these matter wave caustics by placing attractive or repulsive obstacles in the path of a cold atom laser. The results are curving cusps or folds, upward or downward 'V' shapes. These caustics have potential applications for highly precise measurement or timing devices such as interferometers and atomic clocks. |
| Real-world study shows the potential of gait authentication to enhance smartphone security Posted: 10 Dec 2021 06:30 AM PST A study showed that -- within an appropriate framework -- gait recognition could be a viable technique for protecting individuals and their data from potential crime. |
| Artificial intelligence that can discover hidden physical laws in various data Posted: 09 Dec 2021 07:21 PM PST Researchers have successfully developed artificial intelligence technology that can extract hidden equations of motion from regular observational data and create a model that is faithful to the laws of physics. This technology could enable us to discover the hidden equations of motion behind phenomena for which the laws were considered unexplainable. For example, it may be possible to use physics-based knowledge and simulations to examine ecosystem sustainability. |
| Key step toward personalized medicine: Modeling biological systems Posted: 09 Dec 2021 12:32 PM PST A new study shows that machine learning techniques can offer powerful new tools for advancing personalized medicine, care that optimizes outcomes for individual patients based on unique aspects of their biology and disease features. |
| Community of ethical hackers needed to prevent AI's looming 'crisis of trust' Posted: 09 Dec 2021 11:25 AM PST A global hacker 'red team' and rewards for hunting algorithmic biases are just some of the recommendations from experts who argue that AI faces a 'tech-lash' unless firm measures are taken to increase public trust. |
