With increased public and scientific attention driven by factors such as oil price spikes, the need for increased energy security, and concerns over greenhouse gas emissions from fossil fuels, the production of fuels by biological systems is becoming increasingly important as the world seeks to move towards renewable, sustainable energy sources. Biofuels and Bioenergy presents a broad, wide-ranging and informative treatment of biofuels. The book covers historical, economic, industrial, sociological and ecological/environmental perspectives as well as dealing with all the major scientific issues associated with this important topic.With contributions from a range of leading experts covering key aspects, including: • Conventional biofuels.• Basic biology, biochemistry and chemistry of different types and classes of biofuel.• Current research in synthetic biology and GM in the development and exploitation of new biofuel sources.• Aspects relating to ecology and land use, including the fuel v food dilemma.• Sustainability of different types of biofuel.• Ethical aspects of biofuel production. Biofuels and Bioenergy provides students and researchers in biology, chemistry, biochemistry and chemical engineering with an accessible review of this increasingly important subject.

In 1697 Martin Martin, a Gaelic-speaking scholar from Skye, travelled to St Kilda to study the island’s flora and fauna and to learn about the now extinct great auk. Much of the information that he gathered during this expedition was relayed to him by the islanders. Naturalists from Martin down to Robert Atkinson in 1938, not only witnessed the people’s way of life but also the wildlife around them, both priceless assets that have recently won for St Kilda dual World Heritage Site status. Using a huge range of published sources as well as diaries and other personal information, John Love goes even further to explore of the St Kilda archipelago. A Natural History of St Kilda produces a synthesis of what these naturalists and scientists experienced and gives evidence that shows just how important the native flora and fauna were to the survival of the islanders. The result is a fascinating and insightful account of the islands which will appeal not only to naturalists, but also to those who are fascinated by the place, by its human history and by islands in general.

A randomized trial evaluated the efficacy of 17 Early Head Start (EHS) programs. 3,001 low-income families with a pregnant women or an infant under 12 months were assigned to a treatment or control group. Data were collected when children were 1, 2, 3, and 5 years old. Analyses examined (1) impacts at ages 2 and 3 (while services were being offered) and at age 5, and (2) contributions of early education experiences across children's first 5 years of life. Child outcomes included cognition, language, attention, behavior problems, and health; maternal outcomes included parenting, mental health, and employment
