Recently, scientists have claimed that they were able to re-grow a mans severed finger by applying an experimental powder. Known as 'pixie dust', this miracle powder apparently caused the finger to grow back to its original size and shape in 4 weeks and gave the finger nails and finger prints in just 4 months.
