The Mystery of the Frozen Brains is adapted from Marty Chan’s successful radio series The Dim Sum Diaries. Set in a French Canadian town in rural Alberta, the novel develops the coming to awareness of a Chinese boy in a community under the myriad of ethnic influences including French, English and Ukrainian. As serious as the novel’s thematic dispatch is, Chan’s buoyant, gifted humour overrides the tone.

Dark energy is a mysterious force causing the universe to expand in an accelerating manner. Although Edwin Hubble discovered observational proof of expansion in 1929, the first direct evidence for dark energy came from supernova observations in the late 1990s. Untangling complex physics theories with accessible language, informative sidebars, and captivating imagery, this text explores the development and evaluation of scientific theories behind dark energy. Students will learn about the tools and methods scientists use to unravel dark energy's origins, dynamics, and effects on the universe.

Scientists believe that the universe is mostly made up of dark matter, a mysterious substance that is different from the ordinary matter people can touch, smell, see, and interact with. Dark matter cannot be directly observed, but it can be studied by examining its effect on ordinary matter. Simplified explanations of complex scientific concepts and fascinating images will help students understand how physicists employ Kepler's laws of planetary motion, gravitational lensing, particle colliders, and other theories and tools to learn about dark matter. Informative sidebars explore related timely topics in depth, while a Further Reading section provides several resources for additional study.

This engaging volume guides readers into the hearts of massive stars on a journey toward understanding one of the universe's most fascinating occurrences, a supernova event that signifies the end of a star's life. By exploring the origins of star formation and stellar evolutionary paths, students will come to understand the conditions that lead to the explosive deaths of massive stars, including an in-depth look at the groundbreaking detection of Supernova 1987A, the closest supernova observed in the past four hundred years. Additionally, readers will learn about the supernova research currently being conducted by universities across the world and by space agencies such as NASA.

Citizens of Saddleboro are proud to say that theirs is the cleanest town around. So they can't ignore the mysterious death of their mascot, Cock Robin. Some people would like to blame the citizens themselves, but one boy-Tony Isidoro -- suspects there's more to the story.Tony threads his way through a maze of clues: Among other things, the town park is overrun with trillions of ants; nights are quiet because there are no frogs singing; the nearby river contains a dangerous amount of an unknown chemical; and the town dump is emitting strange fumes. What does it all add UP to? It's an eco mystery all right, and it's up to Tony to figure out who really killed Cock Robin.
