| Wearable wireless devices: Low cost radio frequency antenna printed with graphene ink Posted: 15 May 2015 02:49 PM PDT Scientists have moved graphene -- the incredibly strong and conductive single-atom-thick sheet of carbon -- a significant step along the path from lab bench novelty to commercially viable material for new electronic applications. Researchers have printed a radio frequency antenna using compressed graphene ink. The antenna performed well enough to make it practical for use in radio-frequency identification (RFID) tags and wireless sensors, the researchers said. Even better, the antenna is flexible, environmentally friendly and could be cheaply mass-produced.  |
| Used cigarette butts offer energy storage solution Posted: 15 May 2015 11:49 AM PDT Scientists have developed a new way to store energy that also offers a solution to a growing environmental problem.  |
| Exploring mechanics of spider silk to design materials with high strength and low density Posted: 15 May 2015 07:20 AM PDT Researchers explore the mechanics of silk to design materials. Coupling multiscale modeling with emerging microscale 3D-printing techniques, the team enabled a pathway to directly fabricate and test synthetic web structures by design. The lessons learned through this approach may help harness spider silk's strength for other uses, and ultimately inspire engineers to digitally design new structures and composites that are reliable and damage-resistant.  |
| Maybe dark matter is not made up of heavy particles after all Posted: 15 May 2015 05:34 AM PDT Scientists have conducted a simulation that explains the collision between two clusters of galaxies. Clusters of galaxies are the biggest objects that exist in the universe. They are collections of hundreds of thousands of galaxies pulled together by gravity. Rare, extreme examples of clusters caught in the act of colliding seem to be challenging the accepted view that dark matter is made up of heavy particles.  |
| Teacherbot: Can robots do it better? Posted: 15 May 2015 05:34 AM PDT Opinion is often divided over whether digital innovations within education are a value or a threat to teaching.  |
| Lower depression, better mental health during the Great Recession, national study finds Posted: 13 May 2015 11:57 AM PDT Americans had fewer depression diagnoses and better mental health during the Great Recession (2007-09) compared to pre-recession, according to a study. This large, American study also showed that post-recession, women were more likely to be diagnosed with anxiety disorders, while men were less likely to suffer from psychological distress.  |
