Late-Eight writes: "Researchers from the National University of Singapore, have recently developed a new way to make artificial bone from mineralised collagen.

For some time scientists have tried to make nanosized artificial bone materials using various methods, And have recently turned their attention to mineralised collagen, a nanoapatite/collagen composite. This material is highly biocompatible and has the nanostructure of artificial bone. It could be used in bone grafts and bone-tissue engineering, among other applications."

Graphene, a one-atom-thick sheet of carbon, eluded scientists for years but was finally made in the laboratory in 2004 with the help of everyday, store-bough items. This research is an important first step, For developing a way to mass produce metallic graphene that could one day replace copper as the primary interconnect material on nearly all computer chips."

Submission + - The iPhone Lowering the Cost of Medical Imagery

Late-Eight writes: "Viewing medical images traditionally requires dedicated workstations costing tens of thousands of dollars, which in turn are connected to proprietary picture archiving communications and storage (PACS) systems costing millions of dollars more.

Realising the huge potential the iPhone has as a medical tool Heart Imaging Technologies (HeartIT) has recently announced that it's using the iPhone to provide these images and videos to doctors.

Now, instead of commuting to these workstations, doctors can simply click on a web link sent via email by one of their colleagues and instantly view movies of a patient's beating heart halfway around the world. they can even put their colleagues on speakerphone and carry on a medical consultation while simultaneously browsing through the imaging results"

Late-Eight writes: "Scientists at the Georgia Institute of Technology are working on a new type of nanogenerator that could draw necessary energy from flowing blood in the human body. The hope is to incorporate the new nanogenerator into biosensors, environmental monitoring devices and even personal electronics that will require no fuel source, internal or external. Once completed, this new cellular engine could find various applications, even beyond medicine."

There's a lot of fuss about the new scheduling algorithm introduced in the Linux kernel and all that makes me think about what's the point of people reporting better experience running X applications and compiling fat sources with the newest scheduler, if the whole X system looks way too fat? I know nothing about the internal architecture of X but I'm wondering if a redesign could make it work better (and, eventually faster). What I want to say is, that the major CPU hog on an average desktop machine is X, and, that makes me wonder if there's really no way to improve it's performance? Do you think it's time for a rewrite/redesign (and with rewrite, I mean a rewrite not caring about backward compatibility), or is X just performing tasks that can't be done in a better way."

Submission + - Solar Cells Could Be Produced with Inkjet Printers

Late-Eight writes: "From Science Daily: Researchers at New Jersey Institute of Technology (NJIT) have developed an inexpensive solar cell that can be painted or printed on flexible plastic sheets. "The process is simple," said lead researcher and author Somenath Mitra, PhD, professor and acting chair of NJIT's Department of Chemistry and Environmental Sciences. "Someday homeowners will even be able to print sheets of these solar cells with inexpensive home-based inkjet printers. Consumers can then slap the finished product on a wall, roof or billboard to create their own power stations.""
