It is now a widely-used term, but there is still confusion surrounding what it actually is and does. Epigenetics is a new textbook that brings together the structure and machinery of epigenetic modification, how epigenetic modification controls cellular functions, and the evidence for the relationship between epigenetics and disease. It is a valuable source of information about all aspects of the subject for undergraduate students, graduate students, and professionals. Topics Include: • The two forms of epigenetic modification, DNA methylation Paperback • £45.00 and histone acetylation, and how they take place. 2013 * 978-0-8153-6511-2 • How epigenetics controls cell function, including cellular 300pp • 150 illus differentiation and the role of epigenetics in stem cells. • The role of epigenetics in disease, including cancer and mental health, where there is clear evidence of epigenetic Contents: involvement.

There is no doubt, however, in the continued historical and archival importance of this publication, and at no point was it considered that the Record would discontinue. Many of you have collections of the Record dating back to the year you came up, cherish the arrival of each edition, and read it from cover to cover. For the last nine years, Dr Robin Darwall- Smith has consistently produced a Record that is superbly written, accurate and full of interest, and I am sure that readers will want to join me in thanking Robin for his work as Editor in this time.

Introduction The Story Museum was founded as a registered charity in 2003 in response to the clear need to encourage literacy and creativity amongst children and young people and therefore improve life chances. Our mission is to enrich lives, particularly young and disadvantaged lives, through stories. We are achieving this from our most unusual Museum located in the historic centre of Oxford, a city where so many stories - real and fictional - have begun; it is also a place characterised by the educational and social inequality that The Story Museum aims to combat. We create imaginative, immersive exhibitions and events that invite our visitors to explore stories in all forms drawn from across time and around the world. Through this interaction with stories and storytellers, visitors of all ages nurture their creativity, skills and wellbeing. They discover and shape their own narrative. Alongside our public offer, we run participatory projects with targeted groups of children in schools and community settings, intended to address inequalities in access to books, creative learning and cultural capital. Having initially worked in schools and the community, developing our programmes and action research, we found a permanent home in 2010 in a dilapidated old site in the centre of Oxford. Over a 10 year period and several phases of capital works requiring £10m of public and philanthropic support, we transformed it into a place of wonder.

She was named Advertising Woman of the Year in 1982 by the Adwomen Association for her services to the industry. These began in 1964, when she became personal assistant to the director of education of the Advertising Association, helping to organise one of the first Media Business Courses. In 1968, Rosemary joined The Sunday Times to organise its promotions and events. In 1974, she became executive assistant to the managing director of the Thomson Organisation. Rosemary joined CAM in 1976 and ran its courses and seminars, which were then transferred to the Advertising Association in 1986. In June 2013, she was awarded an MBE for services to media education and training. 3 Starting in the way in which it was happily able to continue, the first Media Business Course assembled in 1964 at the Metropole in Brighton. It was, from the outset, popular and successful, with 80 delegates ‘signing in’.

For those women, their gender played no part in their journey through the selection process to Brasenose; they got here through hard work and brilliance. But forty years ago, Oxford University was a different place and 28 women pioneered their way through nearly 500 years of tradition to become the very first female undergraduates in the College. In this issue of the Brazen Notes, we celebrate 40 years of women at Brasenose with memories from some of those who were there at the begining. Left: The College Statutes from 1929.

Vaccination update: 60.4 % of the population in Germany have been vaccinated once, 48 % twice. With the obvious proviso that predictions about the state of the pandemic in September 2021 are impossible to make, we decided to schedule the Weissenburg Symposium September 01 to 04, 2021. Please, be assured that, should Covid-19 conditions deteriorate between now and around the end of August, we would have to postpone or cancel the date of the meeting again.
