Get ready: The "new genetics" promises to change faulty genes of future generations by introducing new, functioning genes using "designer sperm." A new research report appearing online in The FASEB Journal, shows that introducing new genetic material via a viral vector into the sperm of mice leads to the presence and activity of those genes in the resulting embryos. This new genetic material is actually inherited, present and functioning through three generations of the mice tested. This discovery—if successful in humans—could lead to a new frontier in genetic medicine in which diseases and disorders are effectively cured, and new human attributes, such as organ regeneration, may be possible.

One of the world's strangest animals – a legless, leaping fish that lives on land - uses camouflage to avoid attacks by predators such as birds, lizards and crabs, new research shows.
