The Last Days Remembered: A Compatriot Recalls the Deaths of Sacco and Vanzetti in 1927
The emotional and highly publicized case of Nicola Sacco and Bartolomeo Vanzetti became a touchstone and rallying cry for American radicals. In 1920 the two Italian immigrants were accused of murder and although the evidence against them was flimsy, they were readily convicted, in large part because they were immigrants and anarchists. They were executed, despite international protests, on August 23, 1927. Aldino Felicani, printer and publisher of the anarchist paper Controcorrente, was a long-t

UMass Amherst protest ends
A group of minority students exit the New Africa House on the campus of the University of Massachusetts at Amherst. The students hold a press conference in front of the media and a group of supporters. An African American male student reads a prepared statement, announcing the end of the occupation of the New Africa House. The student says that the protesters are pleased that the New Africa House will be restored as a cultural center for African American and third world students. He adds that th

3.2 Structure and behaviour in modern dog breeds
In the 18th and 19th century evolutionary biologists, including Darwin, emphasised the similarities between natural evolution and artificial ‘ improvement’ of livestock under domestication. They believed that studying domesticated animals and plants could illuminate the mechanisms of natural evolution.

10 Living in herds
From the mouse-deer to the elephant, plant eaters come in all shapes and sizes. But how do they manage to flourish on a salad diet? In this unit we will examine the special features that allow them to extract their nutrients from leaves, and see how some plants protect themselves from these predators. This is the fourth unit in the ‘Studying mammals’ series.
5.2 The energy of electromagnetic waves
James Clerk Maxwell (1831-1879) is arguably the father of electromagnetism, and unarguably one of the greatest physicists ever. Einstein called Maxwell's equations 'the most important event in physics since Newton's time, not only because of their wealth of content, but also because they form a pattern for a new type of law'. This unit will examine Maxwell's greatest triumph, the prediction that electromagnetic waves can propagate vast distances through empty space and the realisation that light

Next steps
Water is a natural resource that is vital for human survival and health, although only a tiny fraction of the Earth's supply is available to humans and terrestrial animals. In this unit we look at threats, such as pollution, to water's capacity to support life around the world.
1.1 What happens during an earthquake?
Earthquakes shake the ground surface, can cause buildings to collapse, disrupt transport and services, and can cause fires. They can trigger landslides and tsunami – in short, earthquakes can be very destructive. In this unit you will look at why, where and what happens when they occur and also at how earthquakes are assessed qualitatively and quantitatively.
Checklist of common features
This unit will help you to identify and use information in Science and Nature, whether for your work, study or personal purposes. Experiment with some of the key resources in this subject area, and learn about the skills which will enable you to plan searches for information, so you can find what you are looking for more easily. Discover the meaning of information quality, and learn how to evaluate the information you come across. You will also be introduced to the many different ways of organis
5.2 Barristers In 2008 there were approximately 12,000 barristers in independent practice known as the Bar. Their governing body is the Bar Council. It acts as their regulatory body and sets the requirements for training, qualification and professional development. The main role of a barrister is Author(s):
4.3.1 Ecological tax reforms
Human societies have to take urgent action to end their dependences on fossil fuels. We have to alter the whole path of our development and decision making in order to make our societies both environmentally adaptable and sustainable. This unit takes on the task of trying to chart some of the ways in which it might be possible.
2.2 Transportation disasters Movement of people and goods was one of the main outcomes of the industrial revolution in Britain in the late-eighteenth century, starting with canals, which were displaced gradually by railways. Industrialisation came through innovation in manufacture, especially the development of mass-produced materials such as cast-iron. While the material had been known and used since the Elizabethan period, it could only be made in small quantities by smelting iron ore with charcoal. The Darby fam
18.2.1 Relative advantage
This unit is for designers, engineers, technologists and anyone interested in designing and inventing. It is also for managers and consumers interested in innovation and technical change. The unit will show you how design and innovation can create a more sustainable future. It will also help you understand how innovation comes about and will encourage thinking about environmental and social challenges for the future.
