Sandcastle Worm Bone Glue
The next time you break a bone, your doctor may just reach for the sandcastle worm. Actually, not the actual worm itself but a bone glue made by the animal:
The worm creates a complex water-based mortar to create a home from grains of sand and bits of shell. The adhesive can stick to wet surfaces and doesn’t dissolve at certain pH levels, making it ideal for medical applications. Once it has done its job, it can become water-soluble and dissolve.
The traditional method of healing broken bones by using metal nails, pins and screws is difficult with smaller bones, says Russel Stewart, one of the creators of the synthetic sandcastle worm glue, and scientists have been looking for a suitable adhesive substitute for decades.

New Artificial Bone Made of Wood
Italians scientists have developed a new artificial bone made from wood should be an improvement over the plastic and metal that are now used for implants. Derived from organic material, the new bone substitute will promote faster healing.
To create the bone substitute, the scientists start with a block of wood — red oak, rattan and sipo work best — and heat it until all that remains is pure carbon, which is basically charcoal.
The scientists then spray calcium over the carbon, creating calcium carbide. Additional chemical and physical steps convert the calcium carbide into carbonated hydroxyapatite, which can then be implanted and serves as the artificial bone.

Cast, Away!
If you managed to break a bone and got yourself in an arm cast, chances are you’ll have a permanent marker and a couple of friends’ remarks written all over it.
But when illustrator Taylor White broke her wrist in "an epic acrobatic gravity defying swan-dive into the Norwegian snow," she asked her friend Heather Tompkins to turn the cast into a work of art.

The Shoplifting Dog
A surveillance video at Smith’s Food & Drug grocery store in Idaho has captured a … shoplifting dog!
Surveillance video at Smith’s Food & Drug shows the dog walking in the front door and giving a friendly sniff to a young girl at a checkout stand.
Then the dog headed straight for the pet food in Aisle 16, grabbed the $2.79 bone and made a break for the door, only to be confronted by store manager Roger Adamson.
Adamson says that when the dog didn’t obey his command to surrender the bone, he decided not to force the issue. Adamson tells KSL-TV, "I decided I wanted to keep all my fingers." (Source)
