, best known for leading the team that cloned Dolly, earned his PhD in 1971 for research that included work that led to the birth of Frosty, the first calf born from a frozen embryo.

In this issue of The Scientist, we bring you an article by Ricki Lewis on somatic cell nuclear transfer (p. 12) and a Vision by cloning pioneer Ian Wilmut on why research needs cloned human embryonic stem cells (p. 16). On the research front, things are progressing in leaps and bounds. But in other respects the stem cell phenomenon remains, to borrow Winston Churchill's famous observation on Russia, "a riddle wrapped in a mystery inside an enigma."Take the introduction of therapies. It's a riddl

Researchers have discovered the first protein quality control system in the yeast nucleus.

Researchers at Cornell University's Weill Medical College in New York have created a successful vaccine strategy in mice that uses the immune system's typical antibody response to adenoviruses – which can prevent modified viruses from expressing their payloads and thus diminish the vaccine's efficacy – to boost the antibody response to the vaccine.1By attaching 720 copies of an immunogenic polypeptide from Pseudomonas aeruginosa to the capsid shell of a replication-deficient adenovir
