| New algorithm a Christmas gift to 3-D printing, and the environment Posted: 15 Dec 2014 11:09 AM PST A computer science professor reveals how to print a 3-D Christmas tree efficiently and with zero material waste, using the world's first algorithm for automatically decomposing a 3-D object into what are called pyramidal parts.  |
| Lead islands in a sea of graphene magnetize the material of the future Posted: 15 Dec 2014 09:29 AM PST Researchers have discovered that if lead atoms are intercalated on a graphene sheet, a powerful magnetic field is generated by the interaction of the electrons' spin with their orbital movement. This property could have implications in spintronics, an emerging technology to create advanced computational systems. Graphene is considered the material of the future due to its extraordinary optical and electronic mechanical properties, especially because it conducts electrons very quickly. However, it does not have magnetic properties, and thus no method has been found to manipulate these electrons or any of their properties to use it in new magnetoelectronic devices.  |
| Algorithm identifies networks of genetic changes across cancers Posted: 15 Dec 2014 08:42 AM PST Using a computer algorithm that can sift through mounds of genetic data, researchers have identified several networks of genes that, when hit by a mutation, could play a role in the development of multiple types of cancer. The researchers hope the new genetic insights might aid in the development of new drugs and treatment approaches for cancer.  |
| Fraud-proof credit cards possible with quantum physics Posted: 15 Dec 2014 06:43 AM PST Though corporations and individuals work to improve safeguards, it has become increasingly difficult to protect financial data and personal information from criminal activity. Fortunately, new insights into quantum physics may soon offer a solution.  |
| Control of shape of light particles opens the way to 'quantum internet' Posted: 15 Dec 2014 05:44 AM PST In the same way as we now connect computers in networks through optical signals, it could also be possible to connect future quantum computers in a 'quantum internet'. The optical signals would then consist of individual light particles or photons. One prerequisite for a working quantum internet is control of the shape of these photons. Researchers have now succeeded for the first time in getting this control within the required short time.  |
