1.2 How does it hurt? This is a useful question because once we know the mechanism of pain sensation we can do something about alleviating it. When tissue is injured there follows a rapid release of ‘messenger’ chemicals that stimulate the nerve endings. Electrical impulses are relayed through the nerves to the spinal column and to the brain, which registers the sensation of pain. It usually, but not always, also directs our attention to the site where the damaged tissue initiated the pain message.
Financing Africa's Future: infrastructure, investment and opportunity [Audio]
Speaker(s): Dr Donald Kaberuka, Professor Sir Paul Collier | Low investment in infrastructure is a critical constraint on economic growth in Africa. Dr Kaberuka will assess the challenges and offer his views on the way forward. Donald Kaberuka (@DonaldKaberuka) is the President of the African Development Bank (AfDB). Leonard Wantchekon is Professor of Politics at Princeton University. Paul Collier is a director of the International Growth Centre (IGC), professor of economics and public policy at
Coastal Walk - Stop 12
The stretch of coastline between Slapton Sands and Start Point lighthouse is one of the most beautiful and interesting in the UK. In this podcast, we take you along the way, combining fascinating snippets of information about the natural history, geography, geology and history of the area. Presented by Dr Phil Bradfield, Open University tutor, this walk has something for everyone. This is the twelfth stop on the walk.
7.2.2 The ‘where’ pathway The ‘where’ pathway involves the ventral cochlear nuclei, the superior olivary complex and the inferior colliculus. The superior olivary complex is composed of the lateral superior olive (LSO) and the medial superior olive (MSO). The neurons in the superior olivary complex are the first brainstem neurons to receive strong inputs from both cochleae and are involved in sound localisation. The MSO receives excitatory inputs from the cochlear nuclei on both sides and is tonotopica
2 Looking for relationships In this section, we are going to consider the relationship between quantities in two practical situations and see how to describe these relationships by writing down a general rule or a word formula. Suppose you are planning a visit abroad. Your map marks all the distances between places in kilometres rather than miles. How can you work out what these distances are in miles? Lesson 10 - One Minute Romanian 4.4.1 Partnerships for sustainable consumption Moderate NGOs, progressive businesses and government all have a stake in seeing roundtable partnerships come up with practical steps that can bring sustainability closer. One area that has attracted the attention of all these players is consumption. Directing or limiting consumption is politically difficult for even the NGOs to promote. Similarly, ‘voluntary simplicity’ of the sort lived at Findhorn eco-village (Author(s): Coastal Walk - Stop 17 Acknowledgements Grateful acknowledgement is made to the following sources for permission to reproduce material in this unit: Except for third party materials and otherwise stated (see terms and conditions), this content is made available under a Creative Commons Attribution-NonCommercial-ShareAlik Virtual Maths - 2D Shapes, triangle Impact Investing, Soros-Style Japanese Nuclear Reactors Explained for Students Differences Between Adjectives and Adverbs Female and Male Galapagos Land Iguanas Displaying Courtship Behaviors and Mating Jupiter: the Largest Planet in Our Solar System Virtual Maths, Density formula simulation References What Is The Spring Equinox?

The Soros Economic Development Fund is quasi-philanthropic and invests in high-risk projects in parts of the world most people couldn’t find on a map. But the Fund is self-sufficient and boasts a “blended” portfolio return of 8 percent a year. How do they do it?
Mr. Mac explains to his students what happened to the Japanese nuclear reactors, in kid-friendly language and drawings. (Teacher is John McChesney, Director of Rock-it Science, a Silicon Valley nonprofit organization.) (14:29)
Adjectives are used to describe nouns and pronouns, while adverbs are used to describe verbs and other adverbs. Discover the difference between the two in this video. The teacher shares examples from her computer screen. (1:29)
This short video gives excellent real life footage of a pair of Galapagos Land Iguanas displaying courtship behaviors and mating. This is a great resource to help build background knowledge and to help make real world connections between nature and the classroom. This may not be appropriate for younger students.

(Note: the first few English captions at the bottom of the screen were scrambled.) This video is an adaptation of the breezy Science on a Sphere production by supremely talented members of NASA's Scientific Visualization Studio. This video explores Jupiter's role as the 800-pound gorilla of our solar system, with stops on its fascinating moons and the big red spot. Additional video from NASA JPL and ESA Hubble. (07:30)
