Astronomer Gerard P. Kuiper ignored the traditional boundaries of his subject. Using telescopes and the laboratory, he made the solar system a familiar, intriguing place. “It is not astronomy,” complained his colleagues, and they were right. Kuiper had created a new discipline we now call planetary science. Kuiper was an acclaimed astronomer of binary stars and white dwarfs when he accidentally discovered that Titan, the massive moon of Saturn, had an atmosphere. This turned our understanding of planetary atmospheres on its head, and it set Kuiper on a path of staggering discoveries: Pluto was not a planet, planets around other stars were common, some asteroids were primary while some were just fragments of bigger asteroids, some moons were primary and some were captured asteroids or comets, the atmosphere of Mars was carbon dioxide, and there were two new moons in the sky, one orbiting Uranus and one orbiting Neptune.He produced a monumental photographic atlas of the Moon at a time when men were landing on our nearest neighbor, and he played an important part in that effort. He also created some of the world's major observatories in Hawai‘i and Chile. However, most remarkable was that the keys to his success sprang from his wartime activities, which led him to new techniques. This would change everything.Sears shows a brilliant but at times unpopular man who attracted as much dislike as acclaim. This in-depth history includes some of the twentieth century's most intriguing scientists, from Harold Urey to Carl Sagan, who worked with—and sometimes against—the father of modern planetary science. Now, as NASA and other space agencies explore the solar system, they take with them many of the ideas and concepts first described by Gerard P. Kuiper.

China has been wielding increased influence and soft power in both the Freely Associated States of the Marshall Islands, Micronesia, and Palau, as well as the broader region of Oceania. The authors of this report examine the implications of these activities for the United States, particularly in terms of its defense and foreign policy interests.

Beavers are widely recognised as a keystone species which play a pivotal role in riparian ecology. Their tree felling and dam building behaviours coupled with a suite of other activities create a wealth of living opportunities that are exploited by a range of other species. Numerous scientific studies demonstrate that beaver-generated living environments that are much richer in terms of both biodiversity and biomass than wetland environments from which they are absent. Emerging contemporary studies indicate clearly that the landscapes they create can afford sustainable, cost-effective remedies for water retention, flood alleviation, silt and chemical capture. Beaver activities, especially in highly modified environments, may be challenging to certain land use activities and landowners. Many trialled and tested methods to mitigate against these impacts, including a wide range of non-lethal management techniques, are regularly implemented across Europe and North America. Many of these techniques will be new to people, especially in areas where beavers are newly re-establishing. This handbook serves to discuss both the benefits and challenges in living with this species, and collates the wide range of techniques that can be implemented to mitigate any negative impacts. The authors of this handbook are all beaver experts and together they have a broad range of scientific knowledge and practical experience regarding the ecology, captive husbandry, veterinary science, pathology, reintroduction and management of beavers in both continental Europe and Britain.
