| '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. |
| 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. |
| 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. |
| 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. |
| Machine learning decodes tremors of the universe Posted: 09 Dec 2021 11:25 AM PST Researchers train a neural network to estimate -- in just a few seconds -- the precise characteristics of merging black holes based on their gravitational-wave emissions. The network determines the masses and spins of the black holes, where in the sky, at what angle, and how far away from Earth the merger took place. |
| A new super-cooled microwave source boosts the scale-up of quantum computers Posted: 09 Dec 2021 09:44 AM PST Researchers have developed a circuit that produces the high-quality microwave signals required to control quantum computers while operating at temperatures near absolute zero. This is a key step towards moving the control system closer to the quantum processor, which may make it possible to greatly increase the number of qubits in the processor. |
| A tool to speed development of new solar cells Posted: 09 Dec 2021 09:42 AM PST Researchers have developed a computational simulator that can help predict whether changes to materials or design will improve performance in new photovoltaic cells. |
| Stretchy, washable battery brings wearable devices closer to reality Posted: 09 Dec 2021 06:56 AM PST Researchers have created what could be the first battery that is both flexible and washable. In addition to watches and patches for measuring vital signs, the battery might also be integrated with clothing that can actively change color or temperature. |
| Analog computers now just one step from digital Posted: 09 Dec 2021 05:25 AM PST Engineers have reached a theoretical limit for efficiently converting analog data into digital bits in an emerging computer technology. |
