Hurricane Bertha (2008) weakened to a tropical storm on July 13, and a large upper-level low over the central Atlantic steered it east and southeast. After generally maintaining its strength for several days, an eye redeveloped and convection became more symmetric about the feature on July 18, prompting the NHC to upgrade Bertha to a hurricane around 18:00 UTC that day. The storm rapidly accelerated ahead of a trough off the East Coast of the United States, forcing Bertha into rapidly cooler waters. Its wind field became extremely asymmetric and deep convection near the center dissipated, indicative of an extratropical transition that Bertha
Dolly (sheep) considered related to her being a clone). She has been called "the world's most famous sheep" by sources including BBC News and "Scientific American". The cell used as the donor for the cloning of Dolly was taken from a mammary gland, and the production of a healthy clone therefore proved that a cell taken from a specific part of the body could recreate a whole individual. On Dolly's name, Wilmut stated "Dolly is derived from a mammary gland cell and we couldn't think of a more impressive pair of glands than Dolly Parton's". Dolly was born on 5 July 1996
