An insightful argument that evolution, despite producing complex creatures as different as bacteria, bugs, and humans, must obey scientific laws.
“Physics explains much about why living things look like they do; evolutionary biology provides much of the explanation about how they become like they are.” So writes Cockell (Astrobiology/Univ. of Edinburgh; Astrobiology: Understanding Life in the Universe, 2015), the director of the UK Centre for Astrobiology, in his latest, and he proceeds to make a convincing case. Laws set limits. There is life at temperatures above that of boiling water and below freezing, but not by much. When water is absent or locked up in extremely salty environments, life cannot exist. Honey doesn’t spoil not because it contains any toxins but because its water is unavailable. Our planet’s life is carbon-based and requires a universal solvent, water. Might creatures elsewhere in the universe form themselves from closely related silicon and prefer other common liquids such as ammonia or methane? Moving smoothly from physics to chemistry, biology, and beyond, the author is an amiable guide through some knotty scientific thickets. Ignoring the taboo on equations in popular science writing, Cockell sprinkles them liberally to illustrate their (relative) simplicity. Perhaps the simplest, P = F/A (pressure equals force over area), is critical to the mole, a burrowing animal designed to shift soil by maximizing the force over a small area. Evolution eliminates less efficient burrowers, so all moles, many entirely unrelated, look alike. “If physics and biology are tightly coupled,” writes Cockell, “then life outside Earth, if such life exists, might be remarkably similar to life on Earth, and terrestrial life might be less an idiosyncrasy of one experiment in evolution, but a template for much of life in the universe.”
Many readers will find the equations incomprehensible, but they will relish a lucid, provocative argument that the dazzling variety of organisms produced by 4 billion years of evolution may seem unbounded, but all follow universal laws.Pub Date: June 19, 2018

An alarming account of the “slow-motion catastrophe” facing the world’s largest freshwater system.
Based on 13 years of reporting for the Milwaukee Journal Sentinel, this exhaustively detailed examination of the Great Lakes reveals the extent to which this 94,000-square-mile natural resource has been exploited for two centuries. The main culprits have been “over-fishing, over-polluting, and over-prioritizing navigation,” writes Egan, winner of the J. Anthony Lukas Work-in-Progress Award. Combining scientific details, the stories of researchers investigating ecological crises, and interviews with people who live and work along the lakes, the author crafts an absorbing narrative of science and human folly. The St. Lawrence Seaway, a system of locks, canals, and channels leading to the Atlantic Ocean, which allows “noxious species” from foreign ports to enter the lakes through ballast water dumped by freighters, has been a central player. Biologically contaminated ballast water is “the worst kind of pollution,” writes Egan. “It breeds.” As a result, mussels and other invasive species have been devastating the ecosystem and traveling across the country to wreak harm in the West. At the same time, farm-fertilizer runoff has helped create “massive seasonal toxic algae blooms that are turning [Lake] Erie’s water into something that seems impossible for a sea of its size: poison.” The blooms contain “the seeds of a natural and public health disaster.” While lengthy and often highly technical, Egan’s sections on frustrating attempts to engineer the lakes by introducing predator fish species underscore the complexity of the challenge. The author also covers the threats posed by climate change and attempts by outsiders to divert lake waters for profit. He notes that the political will is lacking to reduce farm runoffs. The lakes could “heal on their own,” if protected from new invasions and if the fish and mussels already present “find a new ecological balance.”
Not light reading but essential for policymakers—and highly recommended for the 40 million people who rely on the Great Lakes for drinking water.Pub Date: March 7, 2017

BOOK REVIEW
It took 14 years to build and it cost 15 million dollars and the lives of 20 workmen. Like the Atlantic cable and the Suez Canal it was a gigantic embodiment in steel and concrete of the Age of Enterprise. McCullough's outsized biography of the bridge attempts to capture in one majestic sweep the full glory of the achievement but the story sags mightily in the middle. True, the Roeblings, father and son who served successively as Chief Engineer, are cast in a heroic mold. True, too, the vital statistics of the bridge are formidable. But despite diligent efforts by the author the details of the construction work — from sinking the caissons, to underground blasting, stringing of cables and pouring of cement — will crush the determination of all but the most indomitable reader. To make matters worse, McCullough dutifully struggles through the administrative history of the Brooklyn Bridge Company which financed and contracted for the project with the help of the Tweed Machine and various Brooklyn bosses who profited handsomely amid continuous allegations of kickbacks and mismanagement of funds. He succeeds in evoking the venality and crass materialism of the epoch but once again the details — like the 3,515 miles of steel wire in each cable — are tiresome and ultimately entangling. Workmanlike and thorough though it is, McCullough's history of the bridge has more bulk than stature.
