| Printing innovations provide 10-fold improvement in organic electronics Posted: 02 Jun 2013 11:46 AM PDT Researchers have developed a new, printing process for organic thin-film electronics that results in films of strikingly higher quality. |
| Posted: 02 Jun 2013 11:46 AM PDT The liver can indeed regenerate itself if part of it is removed. However, researchers trying to exploit that ability in hopes of producing artificial liver tissue for transplantation have repeatedly been stymied: Mature liver cells, known as hepatocytes, quickly lose their normal function when removed from the body. Now, researchers have identified a dozen chemical compounds that can help liver cells not only maintain their normal function while grown in a lab dish, but also multiply to produce new tissue. |
| Specific changes in brain structure after different forms of child abuse Posted: 01 Jun 2013 10:37 AM PDT Different forms of childhood abuse increase the risk for mental illness as well as sexual dysfunction in adulthood, but little has been known about how that happens. Scientists have now discovered a neural basis for this association. The study shows that sexually abused and emotionally mistreated children exhibit specific and differential changes in the architecture of their brain that reflect the nature of the mistreatment. |
| Building 3-D fractals on a nano scale Posted: 31 May 2013 07:39 AM PDT It starts with one 3-D structure with eight planes, an octahedron. This repeats itself to smaller octahedra: 625 after just four steps. At every corner of a new octahedron, a successive octahedron is formed. A truly fascinating 3D fractal 'building' is formed on the micro and nano scale. |
| Artificial magnetic monopoles discovered Posted: 31 May 2013 07:39 AM PDT Scientists have managed to create artificial magnetic monopoles. To do this, they merged tiny magnetic whirls, so-called skyrmions. At the point of merging, the physicists were able to create a monopole, which has similar characteristics to a fundamental particle postulated by Paul Dirac in 1931. In addition to fundamental research, the monopoles may also have application potential. |
| Dairy's carbon footprint: Flatulence tops the list Posted: 31 May 2013 07:17 AM PDT Researchers have conducted a life-cycle analysis of fluid milk that will provide guidance for producers, processors and others throughout the dairy supply chain. The largest contributors were feed production, enteric methane -- gas emitted by the animal itself -- and manure management. |
