Scratch Programming in easy steps introduces readers to Scratch, a programming language that is widely used on the Raspberry Pi and in UK schools. Using Scratch’s highly visual interface, you'll learn how to make games and animations. Along the way, you’ll learn about some important ideas that underpin most programming languages. The book includes examples of games and techniques that readers are invited to customise and build on to make their own programs, and begins with a foreword by Mitchel Resnick, Professor of Learning Research at the MIT Media Lab, which created Scratch.

"This is a teeth-chattering, eyes bulging, shuddering-and-shaking, chills-at-the-back-of-your-neck ghost story. I loved it!"—R.L. Stine, author of the Goosebumps series For fans of Small Spaces and the Goosebumps series by R.L Stine comes a chilling ghost story based on real Chicago history about a malevolent spirit, an unlucky girl, and a haunting mystery that will tie the two together. Claire has absolutely no interest in the paranormal. She's a scientist, which is why she can't think of anything worse than having to help out her dad on one of his ghost-themed Chicago bus tours. She thinks she's made it through when she sees a boy with a sad face and dark eyes at the back of the bus. There's something off about his presence, especially because when she checks at the end of the tour...he's gone. Claire tries to brush it off, she must be imagining things, letting her dad's ghost stories get the best of her. But then the scratching starts. Voices whisper to her in the dark. The number 396 appears everywhere she turns. And the boy with the dark eyes starts following her. Claire is being haunted. The boy from the bus wants something...and Claire needs to find out what before it's too late.

Advances in itch research have elucidated differences between itch and pain but have also blurred the distinction between them. There is a long debate about how somatic sensations including touch, pain, itch, and temperature sensitivity are encoded by the nervous system. Research suggests that each sensory modality is processed along a fixed, direct-line communication system from the skin to the brain. Itch: Mechanisms and Treatment presents a timely update on all aspects of itch research and the clinical treatment of itch that accompanies many dermatological conditions including psoriasis, neuropathic itch, cutaneous t-cells lymphomas, and systemic diseases such as kidney and liver disease and cancer. Composed of contributions from distinguished researchers around the world, the book explores topics such as: Neuropathic itch Peripheral neuronal mechanism of itch The role of PAR-2 in neuroimmune communication and itch Mrgprs as itch receptors The role of interleukin-31 and oncostatin M in itch and neuroimmune communication Spinal coding of itch and pain Spinal microcircuits and the regulation of itch Examining new findings on cellular and molecular mechanisms, the book is a compendium of the most current research on itch, its prevalence in society, and the problems associated with treatment.
