Nature Magazine: Best Science Books Of 2023

Nature Magazine (December 15, 2023):

The AI Dilemma

Juliette Powell & Art Kleiner Berrett-Koehler (2023)

The benefits and harms of social media are intimately tied to the ongoing debate about artificial intelligence (AI). Will AI systems trained partly on social media benefit or harm humanity? In their excellent, sometimes alarming, analysis of engineering, social justice, commerce and government, entrepreneur and technologist Juliette Powell and writer and educator Art Kleiner compare humans developing AI tools to first-time parents. They recommend guiding AI systems “as we would a child towards full adulthood”.

Consciousness

John Parrington Icon (2023)

“The material basis of human consciousness is one of the biggest unsolved issues in science,” admits cellular and molecular pharmacologist John Parrington in his pithy addition to a vast literature dating from the time of ancient Greek philosopher Aristotle. He considers many theories and proposes his own. Humans, he argues, are distinguished by conceptual thought and language, along with skills in designing tools and technologies. The evolution of these powers transformed our brains, creating meaning and consciousness.

Democracy in a Hotter Time

Ed. David W. Orr MIT Press (2023)

Environmentalist David Orr writes in the introduction to this timely collection that the planet faces two interlinked crises: “rapid climate change and potentially lethal threats to democracy”. The US Constitution rigorously protects private property but does not mention ecological systems, he observes. Contributors — almost all US-based — from a wide range of fields examine the need for political reform. The book is in four parts: the nature of democracy; roadblocks to change; policy and law; and education, including academic culture.

Extinctions

Michael J. Benton Thames & Hudson (2023)

When palaeontologist Michael Benton learnt about dinosaurs as a boy, he “loved the fact they were extinct”. They were like real science fiction. Perhaps he also intuited that their extinction permitted his existence. As his deeply informed and readable book reveals, the mass extinction at the end of the Cretaceous period 66 million years ago allowed a new cohort of creatures — including mammals — to “inherit the Earth”, as did four earlier extinction events. Living species represent less than 1% of all the species that have existed.

A Guess at the Riddle

David Z. Albert Harvard Univ. Press (2023)

The physical interpretation of quantum mechanics has been a controversial riddle since the 1920s, when Niels Bohr argued that the atom’s inner workings could not be described in physical terms. Today, many philosophers and physicists disagree, but there’s no consensus on an alternative. Philosopher David Albert’s provocative book argues, in three essays, that Bohr’s quantum-measurement problem starts to make sense if the wave function is understood as the fundamental physical ‘stuff’ of the Universe.

Obesity meets its match

Blockbuster weight loss drugs show promise for a wider range of health benefits

Obesity plays out as a private struggle and a public health crisis. In the United States, about 70% of adults are affected by excess weight, and in Europe that number is more than half. The stigma against fat can be crushing; its risks, life-threatening. Defined as a body mass index of at least 30, obesity is thought to power type 2 diabetes, heart disease, arthritis, fatty liver disease, and certain cancers.

At last, modest headway against Alzheimer’s

Medicine has had little to offer the tens of millions of people worldwide with Alzheimer’s disease, and the few approved treatments have only targeted symptoms. But in January, U.S. regulators greenlit the first drug that clearly, if modestly, slows cognitive decline by tackling the disease’s underlying biology; a second, related treatment is close behind. Neither comes close to a cure, and both have serious risks, but they offer new hope to patients and families.

REVIEWS: THE TOP TEN SCIENCE BOOKS OF 2023

BookList-2023-Science.jpg

Smithsonian Magazine (December 7, 2023) – From stories on the depths of the ocean to the stars in the sky, these are the works that moved us the most this year

Fire Weather: A True Story from a Hotter World  by John Vaillant

Preview thumbnail for 'Fire Weather: A True Story from a Hotter World

In a year when record-setting forest fires raged across Canada and their smoke clouded the skies across North America, and a Maui forest fire incinerated the town of Lahaina in a deadly blaze, the most harrowing book we read about climate change featured a devastating forest fire. In Fire Weather, author John Vaillant crafts a thriller about a cataclysmic inferno that burned through the town of Fort McMurray, Alberta, in May 2016. (We ran an excerpt of the book here.) The blaze generated hurricane-force winds and lightning, and entire neighborhoods burned to the ground under a type of pyrocumulus cloud usually associated with volcanoes. Roughly 100,000 people evacuated what would become the costliest disaster in Canadian history.

Of Time and Turtles: Mending the World, Shell by Shattered Shell by Sy Montgomery

Preview thumbnail for 'Of Time and Turtles: Mending the World, Shell by Shattered Shell

Scuttling Earth for at least 220 million years, turtles have survived more than one mass extinction, including the one that offed dinosaurs. But in a geologic instant, humans have pushed more than half their 360 known species to near-extinction. And in an actual instant, animals slated to live a century or more can be killed—after their shells are crushed by cars, their mouths are snagged by fishhooks or their ponds are drained by developers.

Yet there is hope for some turtles. The Turtle Rescue League in Southbridge, Massachusetts, rehabilitates hundreds of ailing turtles each year. In Of Time and Turtles, author Sy Montgomery joins the small squad in spring of 2020, just as routine life freezes for Covid-19. The book recounts her year with the league, as they incubated eggs, injected antibiotics, mended shattered shells and returned healed patients to nature.

Crossings: How Road Ecology Is Shaping the Future of Our Planet  by Ben Goldfarb

Preview thumbnail for 'Crossings: How Road Ecology Is Shaping the Future of Our Planet

From the start of Ben Goldfarb’s fascinating book on road ecology, Crossings, the reader is peppered with jaw-dropping facts. Some 40 million miles of roadways encircle the Earth. While a half-century ago 3 percent of land-dwelling mammals died on a road, in 2017 that percentage had quadrupled. In 1995, researchers estimated that, in the United States, deer factor into more than a million vehicle crashes annually, injure 29,000 drivers and passengers, and kill more than 200. (We ran an excerpt of the book, with many more surprising facts, here.) And the book is engrossing for other reasons. In it, Goldfarb chronicles roads from California to Canada to Tasmania to show how they have impacted the natural world—and that includes us. He explores how roads have affected everything from butterflies to mountain lions to frogs.

Starborn: How the Stars Made Us (and Who We Would Be Without Them)  by Roberto Trotta

Without the stars, the history of our species would have been very different. That’s the central argument in Roberto Trotta’s engaging homage to the star-studded night sky, Starborn. The stars are more than just pretty: As Trotta shows, our efforts to understand the movements of the stars and planets (and the sun and the moon) played a crucial role in the development of navigation and precision timekeeping. In ancient Egypt, for example, the bright star Sirius was worshipped as a deity, and the start of the new year was signaled when Sirius first became visible in the pre-dawn sky. Seafaring Polynesians, meanwhile, traveled from island to island in the Pacific Ocean by memorizing the positions and movements of some 200 stars—aided by their knowledge of ocean currents, fish, birds and seaweed. Today’s most accurate timekeepers are atomic clocks, which count vibrations of a cesium atom—but even these need to be tweaked based on the sun and stars, because the Earth’s spin is gradually slowing.

Rough Sleepers: Dr. Jim O’Connell’s urgent mission to bring healing to homeless people  by Tracy Kidder

Preview thumbnail for 'Rough Sleepers: Dr. Jim O'Connell's urgent mission to bring healing to homeless people

In Rough Sleepers, author Tracy Kidder profiles a dedicated doctor who treats Boston’s homeless. Harvard-educated physician Jim O’Connell is the founder and president of the Boston Health Care for the Homeless Program. “The Program,” as O’Connell calls it, employs roughly 400 workers to treat more than 11,000 homeless people annually. O’Connell, who refers to the unhoused as “rough sleepers,” a 19th-century British term, is called Dr. Jim by his patients. He treats them in a clinic and drives a van to meet them on the streets. He addresses everything from lice and scabies to more advanced problems that patients have following years of neglect, including large tumors and, in one case, a hernia that dropped below a man’s knees. Aside from care, O’Connell sometimes hands out his own money and gift cards.Report this ad

How Far the Light Reaches: A Life in Ten Sea Creatures by Sabrina Imbler

Preview thumbnail for 'How Far the Light Reaches: A Life in Ten Sea Creatures

Nature is unabashedly queer. We are surrounded by species that live outside our human experience, points of reflective contrast to our terrestrial lives. Sabrina Imbler’s scientifically steeped memoir How Far the Light Reaches revels in these differences, using an aquarium of undersea creatures as foils for significant moments in the author’s life. The preserved remains of a whale are a foil for dissecting a breakup, and our sometimes leering fascination with a marine worm called the sand striker gives form to a meditation on consent. Imbler’s essay “We Swarm,” especially, is a treasure. Squishy marine organisms called salps, which spend part of their lives in aggregations of hundreds of individuals, open a warm recollection of Pride celebrations along the New York shoreline.

The Devil’s Element: Phosphorus and a World Out of Balance  by Dan Egan

Preview thumbnail for 'The Devil's Element: Phosphorus and a World Out of Balance

As chemicals go, phosphorus—number 15 on the periodic table—is something of a paradox. In The Devil’s Element, journalist Dan Egan explains how phosphorus is essential for all life; it can be found in every cell in your body. But it is also combustible and explosive. So-called white phosphorus is a waxy substance that spontaneously combusts when exposed to oxygen—and can cause temperatures to hit 2,370 degrees Fahrenheit. White phosphorus was the key ingredient in the bombs dropped by the Allies on Hamburg, Germany, during World War II, unleashing a firestorm that leveled the city and killed some 37,000 people.Report this ad

My Father’s Brain: Life in the Shadow of Alzheimer’s by Sandeep Jauhar

Preview thumbnail for 'My Father's Brain: Life in the Shadow of Alzheimer's

Alzheimer’s disease robs a person’s memory, yes, but it also causes sweeping behavioral transformations that can include agitation and stubbornness. Those with the condition can become unrecognizable to their loved ones and difficult patients. The slow-acting and irreversible disease “is more feared than death itself,” writes Sandeep Jauhar in My Father’s Brain. After his father starts to show signs of dementia in 2014, Jauhar’s parents move states to be closer to their sons. But the close proximity does little to prevent his father’s Alzheimer’s from upending the lives of family members. Jauhar doesn’t shy away from narrating the ugly and difficult experiences of his father’s irrational behavior, which often leads to sibling fights and frustration for the author.

The Underworld: Journeys to the Depths of the Ocean by Susan Casey

Preview thumbnail for 'The Underworld: Journeys to the Depths of the Ocean

In June, the world paid more attention than usual to deep-sea exploration when OceanGate’s Titan submersible went quiet while exploring the Titanic. Later, the public learned the craft imploded. That was the rare tragic episode of deep-ocean adventures, one years in the making due to the company’s failure to test and heed warnings. But a much more awe-inspiring exploration of the deep has been taking place for decades, and Susan Casey’s enthralling book, The Underworld, documents it in stunning detail. (We ran an excerpt of the book here.) As Casey points out, though you can view maps of Mars on your iPhone, 80 percent of Earth’s seafloor hasn’t been charted in sharp detail.

Better Living Through Birding: Notes from a Black Man in the Natural World by Christian Cooper

Preview thumbnail for 'Better Living Through Birding: Notes from a Black Man in the Natural World

In little more than two minutes captured on video in May 2020, the life of New York City birder Christian Cooper drastically changed. He saw a dog run through a forested section of Central Park and asked its owner, a white woman, to leash her pet in accordance with the law. When she refused, he began to film her with his smartphone, and as he did, she said she would call the police on him and tell them “an African American man is threatening my life.” As the racist incident came to national attention, Cooper quickly became the best-known birder in America. And, amid a hobby that is largely older and white, “the fact that that birder is Black turned heads,” Cooper writes.

Science: Uncovering The Secrets Of Stonehenge

New Scientist (December 5, 2023) – Stonehenge was built between 3000 and 2000 BC and is one of the world’s most famous prehistoric monuments. Each year, the site attracts thousands of visitors during the summer and winter solstices.

Whether used for ceremonial, astronomical or spiritual events, Stonehenge remains a subject of intrigue. Now, using the latest scientific technologies such as radiocarbon dating and 3D laser scanning, archaeologists are understanding how this colossal stone circle was built and what its purpose was, as well as gaining new insight into how our Stone Age human ancestors lived.

New studies even suggest some of the stones could align with the moon during rare lunar events.
