New Web cast: Our Sun- Its Influence on Climate and Life

New Web cast: Astrobiology - Life in Space

Daniel P. Glavin, an astrobiologist at NASA's Goddard Space Flight Center, says the possibility of extraterrestrial life in our solar system is not limited to Mars; other "habitable" worlds might exist including the icy Moons of Jupiter and Saturn, known as Europa and Enceladus. The challenge for scientists and engineers in the next couple of decades, he says, will be to design miniaturized instruments and technologies capable of detecting the signatures of life in our own solar system and beyond. Glavin, who is currently involved in the analysis of organic compounds in meteorites and in the search for extraterrestrial life, presented "Astrobiology: Are We Alone?" In his talk, Glavin described the concept of a "habitable environment" and the conditions on Earth that led to the origin of life. Understanding the basic requirements for life and the prebiotic chemistry that led to the emergence of life on Earth will help guide the search for life beyond Earth. He also gave an overview of the Mars Exploration Program and future plans for sending instrumentation to Mars to explore habitable environments.

New Web cast: Dinosaurs Along the Silk Road

During the past seven years, James M. Clark has been part of a team that found the bones of small dinosaurs mired in mud, stacked one on top of another, in the northern part of Xinjiang, China, near the ancient Silk Road. Clark, who is the Ronald Weintraub Professor of Biology at George Washington University, says a spectacular bestiary of dinosaurs and their contemporaries lies buried in the Gobi Desert of China and Mongolia. The desert, according to Clark, has grudgingly yielded their bones to paleontological expeditions that can endure its rugged terrain, harsh sandstorms and flash floods. In his lecture, Clark showed images of his work in the Gobi and discuss the discoveries made by his expeditions and by others. Many of the discoveries provide critical support for the hypothesis that birds evolved from dinosaurs, and he will discuss this controversial theory.

Edward Guinan, professor of astronomy and astrophysics at Villanova University, is a scientist on NASA-sponsored research programs that explore the behavior of the sun - and stars like the sun- to determine the effects of their radiation, magnetic activity and ejected plasmas on planets and life. In the illustrated lecture, Guinan will discuss how the young sun's high-energy emissions played a major role in the loss of all water on Venus and much of Mars' original atmosphere, and how the Earth survived the early ravages of the young sun. In addition, Guinan will address the effects of the sun's magnetic-generated energy on the Earth's climate, possibly playing a major role in the "Little Ice Age" from 1500 to 1850, a time when the sun had low levels of magnetic activity and the Earth had a cooler climate. He will also discuss the role the sun may have played in global warming over the past 150 years. The lecture will conclude with a discussion of the sun's future and how the sun's ever-increasing luminosity affects the Earth's long-term climate and its habitability.

New Science Reference Guide: Migration of the Monarchs

There are two main populations of monarch butterflies in North America; one in the East and one in the West--new evidence shows that these populations may intermix. Every fall, the monarch begins its migration south to an overwintering site. In the spring the monarch leaves its winter roost and heads northward, about half way back, to lay its eggs on milkweed plants. The offspring of this monarch must continue the journey north on its own. In the fall, this new generation will begin the migration cycle south. To learn more about these amazing creatures, this guide lists selected titles, journal articles and Web sites about monarch butterflies, conservation initiatives, and migration projects.

New LC Science Tracer Bullet: Time

Before the development of modern science, and for most of human existence, time was perceived as a circle or spiral; a cyclical pattern of renewal and rebirth. More familiar to us now is the Western tradition of linear time, a forward moving direction, a flow that represents a line between the past and the future implicit with the idea of progress. As the discoveries of evolution have come to underpin most of modern science so the "arrow of time" has become a given in our collective consciousness. You can'tt see it or smell or taste it or hear it, yet it is of the physical world. We witness evidence of time all around in death and decay. Yet perception of time is largely a human phenomenon and certainly we are the only creatures who measure it, apply tools to it, and create tools to use it. Time is an aspect of the natural world and the characteristics of physical time are determined by the processes of the physical world. It is the essence of cosmology, astronomy, and physics but is equally important in the disciplines of biology and geology. Certainly it is critical to modern technology. The precision of its measurement drives our daily lives. As Tolkien wrote in The Hobbit, it is "This thing all things devours: Birds, beasts, trees, flowers; Gnaws iron, bites steel; Grinds hard stones to meal; Slays king, ruins town And beats high mountain down." From Newtonian to Einsteinian physics and quantum mechanics to thermodynamics and satellite communications, time is of the essence to virtually all scientific disciplines. This bibliographic guide attempts to present a selection of works across the sciences, and is not intended as a comprehensive bibliography, but is designed -- as the name Tracer Bullet implies -- to put the reader "on target."

Updated Science Tracer Bullet: Science Fair Projects

Selected sources provide guidance to students, parents, and teachers throughout the process of planning, developing, implementing and competing in science fair activities. Sources range in suitability from elementary to high school levels. This guide updates LC Science Tracer Bullet 01-4. More specialized titles are listed in Space Science Projects (TB 06-3), Environmental Science Projects (TB 97-6), and Science Projects in Biology (TB 93-6). Not intended to be a comprehensive bibliography, this guide is designed--as the name of the series implies--to put the reader “on target.”

Updated Science Tracer Bullet: Food History

Interdisciplinary in nature, the history of food is a subject well suited to research using the Library’s extensive collections of cookery books, scholarly works, and bibliographies on food history. Researchers also often consult additional sources and primary materials including wartime food manuals, serials of all types, travelers’ memoirs, letters and diaries, advertising, exposition guides, and manufacturers’ pamphlets. This guide, a revision of Library of Congress Science Tracer Bullet 04-1, focuses on works on food history. The intent is to assist researchers in identifying resources and trends in food history studies, through a broad sampling of writings and bibliographies. Rather than being a comprehensive listing, the titles listed here are intended to give an idea of the breadth of information available, with the focus being on works published in English, during the 19th, 20th and 21st centuries, and mainly in the United States, though other time periods and areas have occasionally been included. Not intended to be a comprehensive bibliography, this guide is designed--as the name of the series implies--to put the reader “on target.”

New Science Tracer Bullet: Extraterrestrial Life

Extraterrestrial life is life that originated any place but on Earth.

The origin of all life and the search for its existence in extraterrestrial locales is the focus of this Science Tracer Bullet
