According to Discovery News, Italian scientists have developed a way to use a block of wood and turn it into an artificial bone for implants. They say that it will allow live bones to heal faster after a break than the currently available metal and ceramic implants. The reason they’re using wood is because it closely resembles the physical structure of natural bone.
How is this done ? Well, they start with a block of wood and heat it until all that remains is pure carbon, which is basically charcoal. They then spray calcium over the carbon, creating calcium carbide, then some additional chemical and physical steps convert the calcium carbide into carbonated hydroxyapatite, which can then be implanted.
Sounds very interesting, who would have thought that you could actually create artificial bones from a block of wood ?
Now you can visit the moon for free, well in a sense, you can visit it virtually using Google Earth. Looks like Google has done it again. Forget searching for images of the moon, with the new version of Google Earth you have a choice of which planet you want to view.
I took a little time to play around with it and found it amazing, Google provides high resolution 3d images of key points that have been explored on the moon. In my opinion, learning about space has just become a whole lot more interesting.
Although not as interesting to look at yet, Google Earth also provides views of Mars. It makes me very happy that Google has taken the initiative to provide us with such insightful information.
