Exactly what you read, that useless organ may now have a purpose.
For generations the appendix has been dismissed as superfluous. Doctors figured it had no function. Surgeons removed them routinely. People live fine without them.
Now, some scientists think they have figured out the real job of the troublesome and seemingly useless appendix: It produces and protects good germs for your gut.

The ability of zebrafish to regenerate damaged retinas has given scientists a clue about restoring human vision and could lead to an experimental treatment for blindness within five years.
British researchers said on Wednesday they had successfully grown in the laboratory a type of adult stem cell found in the eyes of both fish and mammals that develops into neurons in the retina.

Damage to the retina -- the part of the eye that sends messages to the brain -- is responsible for most cases of sight loss.

The cells have already been tested in rats with diseased retinas, where they successfully migrated into the retina and took on the characteristics of the surrounding neurons. Now the team is working on the same approach in humans.

In future, these cells could be injected into the eye as a treatment for diseases such as macular degeneration, glaucoma and diabetes-related blindness.

Let us all hope this could be the end of Blindness!
