Zebrafish their larval stages. In 2011, the British Heart Foundation ran an advertising campaign publicising its intention to study the applicability of this ability to humans, stating that it aimed to raise £50 million in research funding. Zebrafish have also been found to regenerate photoreceptor cells and retinal neurons following injury, which has been shown to be mediated by the dedifferentiation and proliferation of Müller glia. Researchers frequently amputate the dorsal and ventral tail fins and analyze their regrowth to test for mutations. It has been found that histone demethylation occurs at the site of the amputation, switching the zebrafish's cells
Living in the Heart of the Beast Living in the Heart of the Beast "Living in the Heart of the Beast" is the title of an extended song written by Tim Hodgkinson in 1975 for the English avant-rock group Henry Cow. It was recorded in 1975 by Henry Cow with Slapp Happy, who had recently merged with Henry Cow after the two groups had recorded a collaborative album, "Desperate Straights" the previous year. "Living in the Heart of the Beast" was the first of two "epic" compositions Hodgkinson wrote for Henry Cow, the second being "Erk Gah" (1976), later known as "Hold to the Zero Burn, Imagine".
