Baking Bites has a short article on the difference between baking powder and baking soda.

Basically they are the same but baking powder has an added acidic agent as well as an ingredient to keep it dry so it won’t react before you need it. For more info read the short article below

Master Bladesmith Bob Kramer shows you how to test the sharpness of a knife and when and how to hone or stone your knife.

Checking your knives sharpness: 

Honing your knife:

What you’re looking at is a picture of a tadpole’s tail. The tail of this tadpole was regenerated after 18 hours after being cut by an hours long exposure to a Sodium Ion cocktail.

The frog tail is a good model for human regeneration because it repairs injury in the same way that people do: each tissue makes more of itself. (In contrast, regeneration in some other animals occurs through transdifferentiation (one cell type turns into another cell type) or adult stem cell differentiation.  Furthermore, though small, the Xenopus larval tail is complex, with muscle, spinal cord, peripheral nerves and vasculature cells.

There are some interesting realizations. This means the injuries are theoretically capable of regenerating after they have been healed.  Since this tadpole uses the same type of cellular regeneration that we do it is even more feasible. Lastly, This isn’t just a bunch of skin cells or similar muscle cells we are talking complex regeneration and the limb didn’t grow abnormalities. No gene therapy was needed and no stem cells were hurt in the regenerations of these limbs. Astounding.
