- Toward quantum computing, spintronic memory, better displays: Nuclear spins control current in plastic LED
- Smartphone app reveals users' mental health, performance, behavior
- Oxides could advance memory devices
| Posted: 18 Sep 2014 11:11 AM PDT Physicists read "spins" in hydrogen nuclei and used the data to control current in a cheap, plastic LED – at room temperature and without strong magnetic fields. The study brings physics a step closer to practical "spintronic" devices: superfast computers, more compact data storage and plastic or organic LEDs, more efficient than those used today in display screens for cell phones, computers and televisions. |
| Smartphone app reveals users' mental health, performance, behavior Posted: 18 Sep 2014 09:14 AM PDT Researchers have built the first smartphone app that automatically reveals college students' mental health, academic performance and behavioral trends. In other words, your smartphone knows your state of mind -- even if you don't -- and how that affects you. The StudentLife app, which compares students' happiness, stress, depression and loneliness to their academic performance, also may be used in the general population -- for example, to monitor mental health, trigger intervention and improve productivity in workplace employees. |
| Oxides could advance memory devices Posted: 17 Sep 2014 10:18 AM PDT The quest for the ultimate memory device for computing may have just taken an encouraging step forward. Researchers have discovered new complex oxides that exhibit both magnetic and ferroelectric properties. |
