FLY

THE UNSUNG HERO OF 20TH-CENTURY SCIENCE

How genetics, with the help of the humble fruit fly, moved into the forefront of modern science.

Brookes (Get a Grip on Genetics, not reviewed) begins where modern biology begins: with Darwin. But the father of evolution was, like his naturalist predecessors, an observer and collector rather than an experimenter. As the 19th century came to a close, a new generation of scientists champed at the bit, anxious to test their theories in the laboratory. As Thomas Hunt Morgan of Columbia University discovered, the fruit fly—short-lived, prolific, easy to raise in a bottle—was an ideal experimental subject. A few years later, his student Herman Muller learned that exposure to X-rays would bring about a rash of bizarre mutations in the flies: legs growing where antennae ought to, or doubled body segments. By the 1930s, this discovery had opened the door to the study of the individual genes responsible for the mutations, and new insight into the developmental patterns of growing organisms. The saliva glands of the fly contain oversized chromosomes that allow scientists to observe individual genes directly. The connection between genetics and evolution was reestablished by Theodosius Dobzhansky, whose studies of wild-fruit-fly populations pointed up the genetic diversity within a single species that is the raw material of evolutionary development. Later experiments with “jumping” genes led to the discovery of a rudimentary form of genetic engineering, of the genetic foundations of behavior, and hints of the secrets of longevity. Brookes gives enough detail of the various experiments to give the layperson a grasp of their significance, and provides an entertaining glimpse of the daily workings of a genetics lab.

A well-written and cohesive treatment of the fundamentals of genetics, as revealed through its favorite experimental subject.

Loads of good explaining, with reminders, time and again, of how much remains unknown, neatly putting the death of science...

A SHORT HISTORY OF NEARLY EVERYTHING

Bryson (I'm a Stranger Here Myself, 1999, etc.), a man who knows how to track down an explanation and make it confess, asks the hard questions of science—e.g., how did things get to be the way they are?—and, when possible, provides answers.

As he once went about making English intelligible, Bryson now attempts the same with the great moments of science, both the ideas themselves and their genesis, to resounding success. Piqued by his own ignorance on these matters, he’s egged on even more so by the people who’ve figured out—or think they’ve figured out—such things as what is in the center of the Earth. So he goes exploring, in the library and in company with scientists at work today, to get a grip on a range of topics from subatomic particles to cosmology. The aim is to deliver reports on these subjects in terms anyone can understand, and for the most part, it works. The most difficult is the nonintuitive material—time as part of space, say, or proteins inventing themselves spontaneously, without direction—and the quantum leaps unusual minds have made: as J.B.S. Haldane once put it, “The universe is not only queerer than we suppose; it is queerer than we can suppose.” Mostly, though, Bryson renders clear the evolution of continental drift, atomic structure, singularity, the extinction of the dinosaur, and a mighty host of other subjects in self-contained chapters that can be taken at a bite, rather than read wholesale. He delivers the human-interest angle on the scientists, and he keeps the reader laughing and willing to forge ahead, even over their heads: the human body, for instance, harboring enough energy “to explode with the force of thirty very large hydrogen bombs, assuming you knew how to liberate it and really wished to make a point.”

Loads of good explaining, with reminders, time and again, of how much remains unknown, neatly putting the death of science into perspective.

A tiny book, not much bigger than a pamphlet, with huge potential impact.

NO ONE IS TOO SMALL TO MAKE A DIFFERENCE

A collection of articulate, forceful speeches made from September 2018 to September 2019 by the Swedish climate activist who was nominated for a Nobel Peace Prize.

Speaking in such venues as the European and British Parliaments, the French National Assembly, the Austrian World Summit, and the U.N. General Assembly, Thunberg has always been refreshingly—and necessarily—blunt in her demands for action from world leaders who refuse to address climate change. With clarity and unbridled passion, she presents her message that climate change is an emergency that must be addressed immediately, and she fills her speeches with punchy sound bites delivered in her characteristic pull-no-punches style: “I don’t want you to be hopeful. I want you to panic. I want you to feel the fear I feel every day. And then I want you to act.” In speech after speech, to persuade her listeners, she cites uncomfortable, even alarming statistics about global temperature rise and carbon dioxide emissions. Although this inevitably makes the text rather repetitive, the repetition itself has an impact, driving home her point so that no one can fail to understand its importance. Thunberg varies her style for different audiences. Sometimes it is the rousing “our house is on fire” approach; other times she speaks more quietly about herself and her hopes and her dreams. When addressing the U.S. Congress, she knowingly calls to mind the words and deeds of Martin Luther King Jr. and John F. Kennedy. The last speech in the book ends on a note that is both challenging and upbeat: “We are the change and change is coming.” The edition published in Britain earlier this year contained 11 speeches; this updated edition has 16, all worth reading.

A tiny book, not much bigger than a pamphlet, with huge potential impact.
