| Great timing, supercomputer upgrade lead to successful forecast of volcanic eruption Posted: 03 Jun 2022 12:33 PM PDT In the fall of 2017, a team of geologists had just set up a new volcanic forecasting modeling program on the Blue Waters and iForge supercomputers. Simultaneously, another team was monitoring activity at the Sierra Negra volcano in the Galapagos Islands, Ecuador. The teams shared their insights and what happened next was the fortuitous forecast of the June 2018 Sierra Negra eruption five months before it occurred. |
| AI ethical decision making: Is society ready? Posted: 03 Jun 2022 09:49 AM PDT With the accelerating evolution of technology, artificial intelligence (AI) plays a growing role in decision-making processes. Humans are becoming increasingly dependent on algorithms to process information, recommend certain behaviors, and even take actions of their behalf. A research team has studied how humans react to the introduction of AI decision making. Specifically, they explored the question, 'is society ready for AI ethical decision making?' by studying human interaction with autonomous cars. |
| An atomic-scale window into superconductivity paves the way for new quantum materials Posted: 03 Jun 2022 09:49 AM PDT Superconductors are materials with no electrical resistance whatsoever, commonly requiring extremely low temperatures. They are used in a wide range of domains, from medical applications to a central role in quantum computers. Superconductivity is caused by specially linked pairs of electrons known as Cooper pairs. So far, the occurrence of Cooper pairs has been measured indirectly macroscopically in bulk, but a new technique can detect their occurrence with atomic precision. |
| Scientists develop a 'fabric' that turns body movement into electricity Posted: 03 Jun 2022 07:01 AM PDT Scientists have developed a stretchable and waterproof 'fabric' that turns energy generated from body movements into electrical energy. |
| 6G component provides speed, efficiency needed for next-gen network Posted: 02 Jun 2022 10:23 AM PDT An international team led by researchers has developed 6G components that will allow future devices to achieve increased speeds necessary for such a technological jump. |
| Time crystals 'impossible' but obey quantum physics Posted: 02 Jun 2022 06:51 AM PDT Scientists have created a 'time-crystal' a two-body system in an experiment that seems to bend the laws of physics. A 'two-level system' is a basic building block of a quantum computer. Time crystals could perhaps be used to build quantum devices that work at room temperature. Time crystals were long believed to be impossible because they are made from atoms in never-ending motion. The discovery shows that not only can time crystals be created, but they have potential to be turned into useful devices. |
| 'Fruitcake' structure observed in organic polymers Posted: 02 Jun 2022 06:51 AM PDT Researchers have analysed the properties of an organic polymer with potential applications in flexible electronics and uncovered variations in hardness at the nanoscale. |
| When AI is the inventor who gets the patent? Posted: 01 Jun 2022 05:00 PM PDT The day is coming -- some say has already arrived -- when new inventions that benefit society are dreamt up by artificial intelligence all on its own. |
| Machine learning models: In bias we trust? Posted: 01 Jun 2022 05:00 PM PDT Researchers find the explanation methods designed to help users determine whether to trust a machine-learning model's predictions can perpetuate biases and lead to less accurate predictions for people from disadvantaged groups. |
| Posted: 01 Jun 2022 12:55 PM PDT Researchers worked with screen-reader users to design VoxLens, a plugin that allows people to interact with digital visualizations made with JavaScript. |
| Study evaluates how to eliminate telemedicine's virtual waiting room Posted: 01 Jun 2022 10:30 AM PDT Researchers have conducted a 10-week study to evaluate how text messaging a link to patients when their doctor is ready provides a way to connect patients and doctors without relying on the virtual waiting room. |
| A 'Goldilocks amount' of time spent online could be good for teenagers' wellbeing Posted: 01 Jun 2022 08:18 AM PDT New research has found further evidence of a relationship between online engagement and mental wellbeing in teenagers. The study contributes to mounting international evidence on the dangers of high levels of digital media use. |
| How structural changes affect the superconducting properties of a metal oxide Posted: 01 Jun 2022 06:21 AM PDT Researchers have discovered how subtle structural changes in strontium titanate, a metal oxide semiconductor, can alter the material's electrical resistance and affect its superconducting properties. The research can help guide future experiments and materials design related to superconductivity and the creation of more efficient semiconductors for various electronic device applications. |
| Photonics: Quest for elusive monolayers just got a lot simpler Posted: 31 May 2022 08:18 AM PDT Optics researchers develop an automated scanning device that can detect 2D monolayers with 99.9 percent accuracy -- surpassing any other method to date -- at a fraction of the cost, in far less time, and with readily available materials. |
| Scientists use AI to update data vegetation maps for improved wildfire forecasts Posted: 31 May 2022 07:27 AM PDT A new technique uses artificial intelligence to efficiently update the vegetation maps that are relied on by wildfire computer models to accurately predict fire behavior and spread. |
| Computer model predicts dominant SARS-CoV-2 variants Posted: 24 May 2022 09:49 AM PDT Scientists have developed a machine learning model that can analyze millions of SARS-CoV-2 genomes and predict which viral variants will likely dominate and cause surges in COVID-19 cases. |
