Feature for Today

On 5 Jul 1841, Thomas Cook (1808-1892) arranged a special train between Leicester and Loughborough in England for a temperance meeting. It is believed to be the first publicly advertised excursion train in England. From this initiative grew the worldwide travel agency Thomas Cook and Son.

Book of the Day

On 5 Jul 1996, Dolly a cloned sheep, was born at the Roslin Institute, Edinburgh, Scotland. Today's book pick is: The Second Creation: Dolly and the Age of Biological Control, by Ian Wilmut, Keith Campbell, Colin Tudge. Written by the noted science author Colin Tudge, the book is based on interviews with Ian Wilmut and Keith Campbell, the scientists who cloned Dolly the sheep. They reveal their contribution to genetic engineering and cloning, and the control that science has over the process of life. The book's aim is to explain the story of how and why they came to cloning sheep and the implications for the future, from curing diseases to human cloning.

Quotations for Today

	Biology can be divided into the study of proximate causes, the study of the physiological sciences (broadly conceived), and into the study of ultimate (evolutionary) causes, the subject of natural history. — Ernst Mayr, German-American biologist (born 5 Jul 1904).
	During this [book preparation] time attacks have not been wanting—we must always be prepared for them. If they grow out of a scientific soil, they cannot but be useful, by laying bare weak points and stimulating to their correction; but if they proceed from that soil, from which the lilies of innocence and the palms of conciliation should spring up, where, however, nothing but the marsh-trefoil of credulity and the poisonous water-hemlock of calumniation grow, they deserve no attention. — Carl Vogt, German-Swiss zoologist, physician and politician (born 5 Jul 1817).
	A theory is a supposition which we hope to be true, a hypothesis is a supposition which we expect to be useful; fictions belong to the realm of art; if made to intrude elsewhere, they become either make-believes or mistakes. — G. Johnstone Stoney, Irish physicist (died 5 Jul 1911).

Deaths
	Antonio de Ulloa (1716-1795) was a Spanish scientist and naval officer who discovered an element. In 1735, the French and Spanish governments sent an scientific expedition to Peru and Ecuador to measure a degree of meridian at Quinto, close to the equator. Ulloa was one of the officers in charge. In 1744, the ship on which he returned was captured by the British. As a prisoner, he was treated respectfully by the English naval officers for they “were not at war with the arts and sciences.” The log of his voyage to Peru published in 1748 contains a description of the new element. Which element did he discover?
Events
	On 5 Jul 1996, Dolly, a cloned sheep, was born. Scientists had replaced the nucleus of an egg cell with the nucleus from a parent cell—in Dolly’s case, an udder cell. Somehow, the egg cell reprogrammed the donated DNA contained within its new nucleus, and Dolly was the result. In which country was Dolly born?
