| Solving algorithm 'amnesia' reveals clues to how we learn Posted: 06 Jul 2022 12:30 PM PDT A discovery about how algorithms can learn and retain information more efficiently offers potential insight into the brain's ability to absorb new knowledge. The findings could aid in combating cognitive impairments and improving technology. |
| Physicists see electron whirlpools Posted: 06 Jul 2022 10:33 AM PDT Physicists have now observed electron whirlpools. Theorists have long predicted electrons should exhibit this hallmark of fluid flow; the findings could inform the design of more efficient electronics. |
| Scientists demonstrate machine learning tool to efficiently process complex solar data Posted: 06 Jul 2022 10:33 AM PDT Big data has become a big challenge for space scientists analyzing vast datasets from increasingly powerful space instrumentation. To address this, a team has developed a machine learning tool to efficiently label large, complex datasets to allow deep learning models to sift through and identify potentially hazardous solar events. The new labeling tool can be applied or adapted to address other challenges involving vast datasets. |
| Physicists work to shrink microchips with first one-dimensional helium model system Posted: 06 Jul 2022 10:33 AM PDT Physicists have created the first one-dimensional helium-based model system to advance research with applications to creating smaller microchips. |
| COVID-19 virus spike protein flexibility improved by human cell's own modifications Posted: 05 Jul 2022 01:22 PM PDT Researchers created atomic-level models of the spike protein that plays a key role in COVID-19 infection and immunity, revealing how the protein bends and moves as it seeks to engage receptors. |
| Using big data to better understand cancerous mutations Posted: 05 Jul 2022 08:22 AM PDT The ideal method of determining what type of cancer mutation a patient has is to compare two samples from the same patient, one from the tumor and one from healthy tissue. Such tests can be complicated and costly, however, so researchers hit upon another idea -- using massive public DNA databases to look for common cell mutations that tend to be benign, so that researchers can identify rarer mutations that have the potential to be cancerous. |
| Advocating a new paradigm for electron simulations Posted: 01 Jul 2022 08:31 AM PDT Researchers improve a widely used simulation method for high-performance computing clusters. |
| Posted: 01 Jul 2022 07:27 AM PDT New research finds that machine-learning algorithms can help health care staff distinguish the two conditions. Researchers show how algorithms may be effective predictive tools using a few simple variables and routinely available structured clinical information. |
| Posted: 30 Jun 2022 11:22 AM PDT By increasing sensory input and promoting multisensory processing, virtual reality may increase the effectiveness of traditional cognitive rehabilitation and exercise training in individuals with MS, according to researchers. |
| Algorithm predicts crime a week in advance, but reveals bias in police response Posted: 30 Jun 2022 08:45 AM PDT A new computer model uses publicly available data to predict crime accurately in eight U.S. cities, while revealing increased police response in wealthy neighborhoods at the expense of less advantaged areas. |
| Posted: 27 Jun 2022 07:02 AM PDT Researchers studied the effect of the 'attitudes' of a semi-autonomous telepresence robot on its human operator. They found that when a person controlled only a part of the body of a semi-autonomous robot, its expressed opinions affected him or her. This work may help assist in the development of new semi-autonomous robots to perform labor more efficiently. |
