A new species of tardigrade has been discovered fossilized in 16-million-year-old Dominican amber, making it only the fourth tardigrade fossil ever found a
A new study reports that by changing just a single gene in the zebrafish genetic code, researchers showed they could begin the creation of an entirely new set of bones and joints.

(CN) Experts can engineer zebrafish, well known for their regenerative abilities, to form an entirely new limb-like appendage an amazing feat accomplished by tweaking just a single gene.
As early life on Earth evolved from single microscopic organisms to the wide host of creatures that walk, fly and swim on this planet today, few evolutionary leaps were as critical as the creation of the jointed limb.
