The first major bioterror event in the United States-the anthrax attacks in October 2001-was a clarion call for scientists who work with “hot” agents to find ways of protecting civilian populations against biological weapons. In The Demon in the Freezer, his first nonfiction book since The Hot Zone, a #1 New York Times bestseller, Richard Preston takes us into the heart of Usamriid, the United States Army Medical Research Institute of Infectious Diseases at Fort Detrick, Maryland, once the headquarters of the U.S. biological weapons program and now the epicenter of national biodefense.
Peter Jahrling, the top scientist at Usamriid, a wry virologist who cut his teeth on Ebola, one of the world’s most lethal emerging viruses, has ORCON security clearance that gives him access to top secret information on bioweapons. His most urgent priority is to develop a drug that will take on smallpox-and win. Eradicated from the planet in 1979 in one of the great triumphs of modern science, the smallpox virus now resides, officially, in only two high-security freezers-at the Centers for Disease Control in Atlanta and in Siberia, at a Russian virology institute called Vector. But the demon in the freezer has been set loose. It is almost certain that illegal stocks are in the possession of hostile states, including Iraq and North Korea. Jahrling is haunted by the thought that biologists in secret labs are using genetic engineering to create a new superpox virus, a smallpox resistant to all vaccines.
Usamriid went into a state of Delta Alert on September 11 and activated its emergency response teams when the first anthrax letters were opened in New York and Washington, D.C. Preston reports, in unprecedented detail, on the government’ s response to the attacks and takes us into the ongoing FBI investigation. His story is based on interviews with top-level FBI agents and with Dr. Steven Hatfill.
Jahrling is leading a team of scientists doing controversial experiments with live smallpox virus at CDC. Preston takes us into the lab where Jahrling is reawakening smallpox and explains, with cool and devastating precision, what may be at stake if his last bold experiment fails.
Every brain begins as a female brain. It only becomes male eight weeks after conception, when excess testosterone shrinks the communications center, reduces the hearing cortex, and makes the part of the brain that processes sex twice as large.
Louann Brizendine, M.D. is a pioneering neuropsychiatrist who brings together the latest findings to show how the unique structure of the female brain determines how women think, what they value, how they communicate, and whom they’ll love. Brizendine reveals the neurological explanations behind why
• A woman remembers fights that a man insists never happened
• A teen girl is so obsessed with her looks and talking on the phone
• Thoughts about sex enter a woman’s brain once every couple of days but enter a man’s brain about once every minute
• A woman knows what people are feeling, while a man can’t spot an emotion unless somebody cries or threatens bodily harm
• A woman over 50 is more likely to initiate divorce than a man
Women will come away from this book knowing that they have a lean, mean communicating machine. Men will develop a serious case of brain envy.

Baffled by benzines? Confused by carboxylic acids? Here's the help you need—in plain English!
Why do you fall in love with one person rather than another? In this fascinating and informative book, Helen Fisher, one of the world's leading experts on romantic love, unlocks the hidden code of desire and attachment. Each of us, it turns out, primarily expresses one of four broad personality types—Explorer, Builder, Director, or Negotiator—and each of these types is governed by different chemical systems in the brain. Driven by this biology, we are attracted to partners who both mirror and complement our own personality type.
Until now the search for love has been blind, but Fisher pulls back the curtain and reveals how we unconsciously go about finding the right match. Drawing on her unique study of 40,000 men and women, she explores each personality type in detail and shows you how to identify your own type. Then she explains why some types match up well, whereas others are problematic. (Note to Explorers: be prepared for a wild ride when you hitch your star to a fellow Explorer!) Ultimately, Fisher's investigation into the complex nature of romance and attachment leads to astonishing new insights into the essence of dating, love, and marriage.
Based on entirely new research—including a detailed questionnaire completed by seven million people in thirty-three countries—Why Him? Why Her? will change your understanding of why you love him (or her) and help you use nature's chemistry to find and keep your life partner.
Nickel, cobalt and platinum group metals are key elements for materials processing. They occur together in one book because they (i) map together on the periodic table (ii) occur together in many ores and (iii) are natural partners for further materials processing and materials manufacturing. They all are, for example, important catalysts – with platinum group metals being especially important for reducing car and truck emissions. Stainless steels and CoNiFe airplane engine super alloys are examples of practical usage.
The product emphasises a sequential, building-block approach to the subject gained through the author’s previous writings (particularly Extractive Metallurgy of Copper in four editions) and extensive experience. Due to the multiple metals involved and because each metal originates in several types of ore – e.g. tropical ores and arctic ores this necessitates a multi-contributor work drawing from multiple networks and both engineering and science.Synthesizes detailed review of the fundamental chemistry and physics of extractive metallurgy with practical lessons from industrial consultancies at the leading international plantsDiscusses Nickel, Cobalt and Platinum Group Metals for the first time in one bookReviews extraction of multiple metals from the same tropical or arctic oreIndustrial, international and multidisciplinary focus on current standards of production supports best practice use of industrial resources
The author has drawn on his own research and the current literature to ensure that appropriate attention is given to topics across the range of modern organic chemistry. The text is unique in its inclusion of a chapter on reactions mediated or catalyzed by transition metals, an area in which mechanistic understanding is now essential. Relatively new topics such as olefin metathesis and cycloaromatization are covered without giving short shrift to more traditional areas such as carbonyl chemistry. The text assumes a basic knowledge of organic chemistry. It can be used either in a formal course or by students working on their own, and will be particularly useful for graduate students studying for qualifying examinations. It will also be useful to students and researchers in biochemistry, pharmacology, and inorganic chemistry.
"This is an excellent and well-presented work.... The author ... has succeeded well in treating the central ideas of reactivity and selectivity in an integrated whole. The clear style of writing, the well chosen examples, and the ... concise summaries of the main points provided at the end of each chapter should enable the reader to easily consolidate what has been learned.... The book is indeed a little work of art."
-- Jens Hartung, Angewandte Chemie International Edition
"I have taught a one-credit course with this book for three years, and, uniformly, the students have rated this book highly for its clarity and for the scope of the problems. ... This book does an excellent job at its stated goal: 'to teach students to come up with reasonable mechanisms for reactions they have never seen before.'"
-- Amy Howell, Synthesis
"I have just finished my first year of graduate studies in organic chemistry at Duke University. I just wanted to let you know how much your book got me through the past year of course work.... When it came to mechanisms, I found the clarity and thoroughness I needed only in your book. It was impressive how you were able to present so much information in a clear and comprehensive manner yet keep the book so manageable in size. In addition to the text, I also was able to benefit from the problems.... Great practice!! The on-line answers are much better than looking up answers by reference.... I am reading it again this summer in preparation for my preliminary exam next spring."
-- David Gooden
Organic Synthesis: The Disconnection Approach, 2nd Edition introduces this important technique, to help students to design their own organic syntheses. There are forty chapters: those on the synthesis of given types of molecules alternate with strategy chapters in which the methods just learnt are placed in a wider context.
