| Engineers develop new control electronics for quantum computers that improve performance, cut costs Posted: 29 Apr 2022 11:49 AM PDT Quantum computing experiments now have a new control and readout electronics option that will significantly improve performance while replacing cumbersome and expensive systems. |
| 'Eye-catching' smartphone app could make it easy to screen for neurological disease at home Posted: 29 Apr 2022 11:49 AM PDT Researchers have developed a smartphone app that could allow people to screen for Alzheimer's disease, ADHD and other neurological diseases and disorders -- by recording closeups of their eye. The app uses a smartphone's built-in near-infrared camera and selfie camera to track how a person's pupil changes in size. These pupil measurements could be used to assess a person's cognitive condition. |
| Self-assembled logic circuits created from proteins Posted: 28 Apr 2022 01:16 PM PDT In a proof-of-concept study, researchers have created self-assembled, protein-based circuits that can perform simple logic functions. The work demonstrates that it is possible to create stable digital circuits that take advantage of an electron's properties at quantum scales. |
| Bay Area storms get wetter in a warming world Posted: 28 Apr 2022 12:22 PM PDT Researchers used supercomputers to run high-resolution climate simulations that show how historically-impactful storm events could look in a warmer world. The researchers simulated five of the most powerful storms that have hit the San Francisco Bay Area since 1984, then projected how these historical storms would look in 2050 and 2100. They determined that some of these extreme events would deliver 26-37 percent more rain by 2100. |
| Scientific advance leads to a new tool in the fight against hackers Posted: 28 Apr 2022 09:54 AM PDT A new form of security identification could soon see the light of day and help us protect our data from hackers and cybercriminals. Quantum mathematicians have solved a mathematical riddle that allows for a person's geographical location to be used as a personal ID that is secure against even the most advanced cyber attacks. |
| Electronics can grow on trees thanks to nanocellulose paper semiconductors Posted: 26 Apr 2022 12:36 PM PDT A team in has created a nanocellulose paper semiconductor with both trans-scalability of structural design and wide electrical property tunability. The structure and function of the nanopaper semiconductor could be customized according to the desired use, allowing diverse applications as a wearable water-vapor-selective sensor and an enzymatic biofuel cell electrode for energy generation. This achievement is expected to open new doors for sustainable electronics that are completely derived from plant materials. |
| Machine learning model can steer traumatic brain injury patients to life-saving care Posted: 26 Apr 2022 07:11 AM PDT A new machine-learning algorithm can analyze brain scans and relevant clinical data to predict survival and recovery after severe traumatic brain injury. |
