VALHALLA, N.Y. — As soon as Doris Bucher learned that a new strain of swine flu had turned up in the United States, she e-mailed the Centers for Disease Control and Prevention offering to send materials that might be useful in making a vaccine.

On Darwin’s ‘On the Origin of Species’
On Darwin's 'On the Origin of Species'
In addition to being the 200th anniversary of Darwin's birth, 2009 is the 150th anniversary of the publication of his fundamental work, "On the Origin of Species." As with many original sources, it is known mostly by reputation. Few people who are not biologists read Darwin in the original. But his writing can still offer surprises, insights and pleasures, and it can be sampled here, with selections by prominent scientists of their favorite passages and discussions of why these passages are important.

Richard Wrangham, a primatologist and anthropologist, has spent four decades observing wild chimpanzees in Africa to see what their behavior might tell us about prehistoric humans. Dr. Wrangham, 60, was born in Britain and since 1989 has been at Harvard, where he is a professor of biological anthropology. His book, “Catching Fire: How Cooking Made Us Human,” will be published in late May. He was interviewed over a vegetarian lunch at last winter’s American Association for the Advancement of Science meeting in Chicago and again later by telephone. An edited version of the two conversations follows.

Gene therapy, long on promise and so far very short on fulfillment, may be achieving a glimmering of success in a treatment for hemophilia B, a disease in which the blood does not clot properly.

A Census Taker for Penguins in Argentina

In the early 1980s, a Japanese company went to the Argentine government and said, “We’d like a concession to harvest your penguins and turn them into oil, protein and gloves.” There was a public outcry. This was during a military dictatorship when dissidents were being thrown into the ocean from airplanes. And yet people said, “We object to having our penguins harvested.”
