| Algorithms empower metalens design Posted: 17 May 2022 01:05 PM PDT Researchers have developed a new method for designing large-scale metasurfaces that uses techniques of machine intelligence to generate designs automatically. The method will enable new metasurface designs that can make an impact on virtual or augmented reality, self-driving cars, and machine vision for embarked systems and satellites. |
| Early warning system forecasts who needs critical care for COVID-19 Posted: 17 May 2022 08:22 AM PDT An algorithm can accurately predict which hospitalized patients are at the highest risk of death and require critical care, regardless of immune protection status and virus variant. |
| New silicon nanowires can really take the heat Posted: 17 May 2022 08:22 AM PDT A research team has demonstrated an ultrathin silicon nanowire that conducts heat 150% more efficiently than conventional materials used in advanced chip technologies. The device could enable smaller, faster, energy-efficient microelectronics. |
| Posted: 17 May 2022 06:48 AM PDT Australia has suffered a significant drop in teenage maths proficiency in the past 20 years -- sliding from 11th in the OECD rankings to 29th place out of 38 countries, prompting widespread debate over potential curriculum changes. One researcher says hand gestures could stop the slide. |
| New method melds data to make a 3-D map of cells' activities Posted: 16 May 2022 06:31 PM PDT Engineers are using a cell's surroundings to help biologists make more sense of gene expression information. Their new system could open the door to identifying rare cell types and choosing cancer treatment options with new precision. |
| Scientists identify characteristics to better define long COVID Posted: 16 May 2022 06:31 PM PDT Researchers have identified characteristics of people with long COVID and those likely to have it. Scientists used machine learning techniques to analyze an unprecedented collection of electronic health records (EHRs) available for COVID-19 research to better identify who has long COVID. |
| Shaping the future of light through reconfigurable metasurfaces Posted: 16 May 2022 12:15 PM PDT Harnessing the power of 'phase-change' materials, researchers have demonstrated how reconfigurable metasurfaces -- artificial materials with extraordinary optical properties -- are crucial to the future of nanotechnology. |
| Development of an ensemble model to anticipate short-term COVID-19 hospital demand Posted: 09 May 2022 08:20 AM PDT Scientists identified the most relevant predictive variables for anticipating hospital demand and proposed using an ensemble model based on the average of the predictions of several individual models. |
| New computational tool to interpret clinical significance of cancer mutations Posted: 06 May 2022 12:14 PM PDT Researchers have developed a new tool to help researchers interpret the clinical significance of somatic mutations in cancer. The tool, known as CancerVar, incorporates machine learning frameworks to go beyond merely identifying somatic cancer mutations and interpret the potential significance of those mutations in terms of cancer diagnosis, prognosis, and targetability. |
