In its childhood, science was an amateur activity. Grown men and women collected shells or beetles, pressed and sketched plants, peered
through telescopes or microscopes, and had a good chance of discovering something new.
But grown-up science has become quite forbidding to anyone with math anxiety and without a Ph.D. The massive, intricate instruments and
the supercomputers that run them are light-years removed from the hands-on tools and direct immersion in nature that made early science
an accessible adventure. These days if you love science, you either spend years in preparation and specialization, or you love it from afar. Right?
So how did a twenty-four-year-old Dutch schoolteacher discover a new intergalactic phenomenon within a week of beginning to do astronomy?
Read about the new phenomenon in which civilians become the footsoldiers of scienceand sometimes even its heroes. It could happen to you.. more

After its successful final servicing mission, the Hubble Space Telescope appears to be better than ever. But the triumph was bittersweet as astronauts released the Hubble from their grasp for the last timeand faced the uncertain future of human (versus robotic) space exploration. Thanks to a book reviewed in our October 2008 issue, I couldnt help flashing back to the first Hubble servicing mission, in 1993the one that turned Hubble from what might be the greatest catastrophe to hit American astronomy ever into a triumph . . . and a turning point in human evolution. more

Youve heard about crunchy consconservative and evangelical Christian environmentalists who preach stewardship of the Creation, even going so far as to forge an alliance with agnostic (at best) scientist E.O. Wilson. Well, now Malaysia has crunchy mullahs. Following up on well-received sermons exhorting the faithful to protect enangered turtles, some mosques will feature sermonscrafted in collaboration with the World Wildlife Fundthat find grounds in Quranic scripture to protect tigers and elephants and their habitat. more

Charles Darwin is an icon; he is, to many of us, more of a meme than a man. He came to life for me for really the first time in the course of fact checking this months marvelous 200th-birthday tribute, Richard Milners Seeing Corals with the Eye of Reason. No accident: Milner, an NH contributing editor, has virtually dedicated his life to bringing the real Charles Darwin back alive. Here are a few of the things I didnt know about Darwin that you may or may not, from his oft-misrepresented thought to his beguiling humanity. In this 200th year of his birth and profound, pervasive influence on our world, theres no more fitting celebration than to get to know him, or to know him better. more

Kin selection as an explanation for the evolution of altruism seems so intuitively right that its hard to accept that its wrong, but thats what the eminent sociobiologist E.O. Wilsona former believerhas concluded. Plenty of other eminent scientists, such as Richard Dawkins, still disagree with him.
If not kin selection, then what is driving the development of the remarkable degree of self-sacrifice in these colonies? Wilson, as his new Superorganism book with Hölldobler, and Dunns review of it, make clear, has become a convert to the idea of group selection in social insects . . . and possibly in human societies, too. more

How do you pass on a gene for self-sacrifice? It sounds like an oxymoron. All the way up and down the evolutionary scale, from single-celled amoebas to human beings, the persistence of a tendency to help others at ones own expense is a conundrum for natural selection, wrote Joan E. Strassman and David C. Queller in their September 2007 article, Altruism Among Amoebas:
If an individual does not pass on its genes to offspring, for whatever reason, those genes will be that much scarcer in the next generation. The process is blind, ruthless, and competitive, and it would seem to shut the door on genes for altruism. . . . [H]ow can self-sacrifice be a successful strategy?
Since Ive been working for Natural History, weve run what adds up, in my mind, to a series of articles on this conundrum, ranging all the way up and down the evolutionary scaleand sometimes across species boundaries. more

The Man Who Planted Trees, a beautiful 1987 animated film, can be watched for free online. It’s about half an hour long, absolutely riveting, beautifully drawn, and very moving. Besides that, it’s an object lesson in the life-giving, reverberating power of the simple act of planting trees. more
