From the use of personal products to our consumption of food, water, and air, people are exposed to a wide array of agents each day-many with the potential to affect health. Exposure Science in the 21st Century: A Vision and A Strategy investigates the contact of humans or other organisms with those agents (that is, chemical, physical, and biologic stressors) and their fate in living systems. The concept of exposure science has been instrumental in helping us understand how stressors affect human and ecosystem health, and in efforts to prevent or reduce contact with harmful stressors. In this way exposure science has played an integral role in many areas of environmental health, and can help meet growing needs in environmental regulation, urban and ecosystem planning, and disaster management. Exposure Science in the 21st Century: A Vision and A Strategy explains that there are increasing demands for exposure science information, for example to meet needs for data on the thousands of chemicals introduced into the market each year, and to better understand the health effects of prolonged low-level exposure to stressors. Recent advances in tools and technologies-including sensor systems, analytic methods, molecular technologies, computational tools, and bioinformatics-have provided the potential for more accurate and comprehensive exposure science data than ever before. This report also provides a roadmap to take advantage of the technologic innovations and strategic collaborations to move exposure science into the future.

The Indian National Science Academy was established in January 1935 with the objective of promoting science in India and harnessing scientific knowledge for the cause of humanity and national welfare. In 1968 it was designated as the adhering organisation in India to the International Council for Scientific Union (ICSU) on behalf of the Government of India. Over the years, the Academy has published a number of journals, volumes, biographical memoirs, etc. The year 2009–2010 will be specially celebrated to mark the Platinum Jubilee of the Academy. Many programmes are planned in different centres in India on this occasion. In addition, the Academy has decided to publish a number of special volumes on different s- jects ranging from earth sciences to life sciences. This volume is on Physics and Chemistry of the Earth’s Interior. One of the main objectives of geophysicists is to establish the internal structure of the earth as revealed by seismic tomography. It is also their primary goal to correlate geophy- cal data to reveal thermal and chemical state of the crust, mantle and core of the earth. In - der to interpret seismic velocities and associated density and elastic properties in terms of mineralogical and petrological models of the earth’s interior, thermodynamic and hi- pressure temperature data from mineral physics are essential. With the advent of different types of multi-anvil and laser-heated diamond anvil equipment, it is now possible to simulate conditions prevalent even in the lower mantle and core of the earth.

The National Oceanic and Atmospheric Administration (NOAA) commissioned TERC to complete a review of science education standards for all 50 states. The study analyzed K-12 Earth science standards to determine how well each state addresses key Earth-science content, concepts and skills. This report reveals that few states have thoroughly integrated climate, weather and oceans studies into their curriculum. Earth science integrates oceanography, meteorology, geology, biology, chemistry, physics and other disciplines to understand Earth's processes as an integrated system. In addition to practical applications in a variety of fields, Earth science also addresses environmental challenges such as climate change, hurricanes, and ocean issues. The study examined how state standards support integrating materials such as remotely sensed imaging, satellite photography, and data visualization tools into classroom education. Unfortunately, this study shows that Earth system science education in the U.S. is in need of significant improvement. The report shows a great variation in the states' Earth science education standards. This report is a call to action showing a pressing need for systematic reform. The recommendations listed in this report to revolutionize K-12 Earth science education are: (1) The concepts and approaches comprising the seven different review criteria should be viewed as an interrelated suite of perspectives, all supporting the core principles of quality Earth systems science education; (2) The ocean literacy principles and concepts could be enhanced by better incorporating a systems perspective; (3) Develop a comprehensive set of atmosphere, weather, and climate literacy principles and concepts, similar in format to the ocean literacy principles and concepts; (4) Directly participate in state science standards revision processes. (5) Ensure that Web-based access to data and analysis tools are usable by the K-12 education community; (6) Participate in the development of quality state and national science assessments; (7) Demonstrate that modern "revolutionary" Earth science perspectives and approaches to teaching result in deep student learning of science concepts and thinking skills; (8) Establish Earth system science as a science course widely viewed as being equally or more challenging as the classic high-school sciences of biology, chemistry, and physics; and (9) Tirelessly persist in promoting the revolution in Earth system science education with the understanding that improvements will occur incrementally. The following are appended: (1) Ocean Literacy Principles and Fundamental Concepts; and (2) Detailed Analysis of Ocean Literacy Concepts. (Contains 2 tables and 8 figures.).
