IBM researchers have demonstrated a graphene circuit which integrates all circuit components onto a single wafer made of silicon carbide. Graphene is a mesh of carbon atoms that's one atom thick. Integrating it monolithically -- meaning in one unit -- with other materials is a problem researchers have been grappling with since 2004, when the material's properties were first demonstrated. IBM announced the demonstration of its monolithically integrated graphene circuit in a paper published Friday in the journal Science.

Has the Time Come for an Android Market Drug Test?

Android apps are becoming more popular as the Android operating system gains ground in the mobile market. IDC expects Android to take more than 40 percent of the worldwide smartphone market in the second half of 2011. However, with Android's growing popularity comes a growing risk of malware attacks. Malware has hit apps in the Android Market on at least two notable occasions this year, in March and then in early June, forcing Google to pull about 75 tainted apps in all. Improper coding also affects users of Android apps.

Hypervisor Fight Is Good for Customers, Good for FOSS

There have been many changes in the market and technology since Citrix acquired XenSource and a major stewardship stake in the Xen open source hypervisor four years ago. Red Hat's 2008 Qumranet acquisition and subsequent push behind the Linux-integrated Kernel-based Virtual Machine hypervisor has added to the disruption. One thing, though, remains the same: the intense competition among these open source hypervisors in the enterprise market.
