Solid research into the dilemmas regarding genetic screening and how it is used for fetuses and newborns.

THE GENE MACHINE

HOW GENETIC TECHNOLOGIES ARE CHANGING THE WAY WE HAVE KIDS—AND THE KIDS WE HAVE

When scientific ability and human desire coalesce into a potent tool that can profoundly change life.

As more research is conducted on the human genetic code, scientists, doctors, and parents will have an increasing number of options regarding how this information is used. Beginning with Tay-Sachs, a fatal neurological disease commonly found among Ashkenazi Jews, former Time health and medicine columnist Rochman clearly discusses how genetic screening has helped Jews avoid passing the disease on to their offspring. She also explores the multiple layers of morality and ethics involved in the process of prenatal carrier screening. For those with a definite genetic predisposition to a life-threatening or deadly defect, the testing can provide answers while there is still time to discuss pregnancy or abortion. But what are the options if a fetus is diagnosed with cystic fibrosis, Down syndrome, or a host of other abnormalities? With the use of in vitro fertilization, doctors can implant only those embryos that show no signs of a genetic abnormality, and parents are making decisions about their offspring based on these genetic tests. These are just some of the difficult scenarios Rochman outlines in the narrative, which is full of interviews with doctors, parents, and those in the scientific community. The author also examines the conflicts surrounding the knowledge of potential problems that only manifest later in life, such as Alzheimer’s disease—should parents be told their child is predisposed? For some parents, the advance knowledge created a state of anxiety, inhibiting their ability to fully relax and enjoy the many nonafflicted years their child had before them. Knowledge can be power, but as Rochman rightly points out, sometimes the ability to know doesn’t mean one should know.

Solid research into the dilemmas regarding genetic screening and how it is used for fetuses and newborns.

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.

As much a work of philosophy as of physics and full of insights for readers willing to work hard.

THE ORDER OF TIME

Undeterred by a subject difficult to pin down, Italian theoretical physicist Rovelli (Reality Is Not What It Seems: The Journey to Quantum Gravity, 2017, etc.) explains his thoughts on time.

Other scientists have written primers on the concept of time for a general audience, but Rovelli, who also wrote the bestseller Seven Brief Lessons on Physics, adds his personal musings, which are astute and rewarding but do not make for an easy read. “We conventionally think of time,” he writes, “as something simple and fundamental that flows uniformly, independently from everything else, uniformly from the past to the future, measured by clocks and watches. In the course of time, the events of the universe succeed each other in an orderly way: pasts, presents, futures. The past is fixed, the future open….And yet all of this has turned out to be false.” Rovelli returns again and again to the ideas of three legendary men. Aristotle wrote that things change continually. What we call “time” is the measurement of that change. If nothing changed, time would not exist. Newton disagreed. While admitting the existence of a time that measures events, he insisted that there is an absolute “true time” that passes relentlessly. If the universe froze, time would roll on. To laymen, this may seem like common sense, but most philosophers are not convinced. Einstein asserted that both are right. Aristotle correctly explained that time flows in relation to something else. Educated laymen know that clocks register different times when they move or experience gravity. Newton’s absolute exists, but as a special case in Einstein’s curved space-time. According to Rovelli, our notion of time dissolves as our knowledge grows; complex features swell and then retreat and perhaps vanish entirely. Furthermore, equations describing many fundamental physical phenomena don’t require time.

As much a work of philosophy as of physics and full of insights for readers willing to work hard.
