We are now starting to understand that the role of the estrogen receptor is not identical in all tissues. Important nongenomic effects for sex hormones have also been described. Hormone replacement therapy (HRT) has produced effects on health risks: some are reduced, some are increased, and the rest remain uncertain. HRT is being used by an increasing number of women to alleviate climacteric symptoms in the perimenopausal period and to prevent osteoporosis and cardiovascular disease later. Positive effects on Alzheimer's disease and dementia on the one hand, and an increase in venous thrombosis on the other, are currently being reported by several groups. Both the preventive benefits and the risk of breast cancer seem to be linked to long-term and current use. HRT requires further testing through specific clinical trials, currently underway in the United States, before confident recommendations may be made about the full range of benefits and risks.

the drama of the front lines.”

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.
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.
