    Written with Barnard’s cooperation and with input from dozens of associates, drivers and rivals, this biography tells the entire story, both personal and professional, of a British design genius. Barnard’s technical achievements are explored in detail — and in accessible language — with special emphasis on his brilliant initiatives while at McLaren (the first carbon-fibre composite chassis) and Ferrari (the first semi-automatic gearbox). The Perfect Car is also a human-interest story, telling a tale of innovation under intense pressure while Barnard endeavoured to maintain a stable family life. This is a landmark book that will be relished by anyone interested in motorsport and design.

    And imagine how that would change the outlook of the 5 million Americans who suffer from Alzheimer’s disease and other dementias, not to mention their families, loved ones, and caretakers. A neurologist who’s been specializing in dementia and memory loss for more than 20 years, Dr. Gayatri Devi rewrites the story of Alzheimer’s by defining it as a spectrum disorder—like autism, Alzheimer’s is a disease that affects different people differently. She encourages people who are worried about memory impairment to seek a diagnosis, because early treatment will enable doctors and caregivers to manage the disease more effectively through drugs and other therapies. Told through the stories of Dr. Devi’s patients, The Spectrum of Hope is the kind of narrative medical writing that grips the reader, humanizes the science, and offers equal parts practical advice and wisdom with skillful ease. But beyond the pleasures of great reading, it’s a book that offers real hope. Here are chapters on how to maintain independence and dignity; how to fight depression, anxiety, and apathy; how to communicate effectively with a person suffering from dementia. Plus chapters on sexuality, genetics, going public with the diagnosis, even putting together a bucket list—because through her practice, Dr. Devi knows that the majority of Alzheimer’s patients continue to live and work in their communities. They babysit their grandkids, drive to the store (or own the store), serve their clients, or otherwise live fulfilling lives. That’s news that 5 million people are waiting to hear.

    Comparing gene sequences, examining atomic structures of proteins, and looking into the geochemistry of rocks have helped explain evolution in more detail than ever before. Nick Lane expertly reconstructs the history of life by describing the ten greatest inventions of evolution (including DNA, photosynthesis, sex, and sight), based on their historical impact, role in organisms today, and relevance to current controversies. Who would have guessed that eyes started off as light-sensitive spots used to calibrate photosynthesis in algae? Or that DNA’s building blocks form spontaneously in hydrothermal vents? Lane gives a gripping, lucid account of nature’s ingenuity, and the result is a work of essential reading for anyone who has ever pondered or questioned the science underlying evolution’s greatest gifts to man.

    Essentially, you make an initial guess, and then get more data to improve it.

    On November 1, 2017, the Houston Astros defeated the Los Angeles Dodgers in an epic seven game battle to become 2017 World Series champs. For the Astros, the combination of a magnificently played series, a 101-victory season, and the devastation Hurricane Harvey brought to their city was so incredible it might give Hollywood screenwriters pause. The nation's fourth-largest city, still reeling in the wake of disaster, was smiling again. The Astros' first-ever World Series victory is a great baseball story, but it's also the story of a major American city -- a city (and a state) that the rest of the nation doesn't always love or understand--becoming a sentimental favorite because of its grace and good will in response to the largest natural disaster in American history. The Astros' miracle season is also the fascinating tale of a thoroughly modern team. Constructed by NASA-inspired analytics, the team's data-driven system took the game to a more sophisticated level than the so-called Moneyball approach. The team's new owner, Jim Crane, bought into the system and was willing to endure humiliating seasons in the baseball wilderness with the hope, shared by few initially, that success comes to those who wait. And he was right. But no data-crunching could take credit for a team of likeable, refreshingly good-natured young men who wore "Houston Strong" patches on their jerseys and meant it--guys like shortstop Carlos Correa, who kept a photo in his locker of a Houston woman trudging through fetid water up to her knees. The Astros foundation included George Springer, a powerful slugger and rangy outfielder; third-baseman Alex Bregman, whose defensive play and clutch hitting were crucial in the series; and, of course, the stubby and tenacious second baseman Jose Altuve, the heart and soul of the team.Hurricane Season is Houston Chronicle columnist Joe Holley's moving account of this extraordinary team--and the extraordinary circumstances of their championship.

    Richard Johnson, who oversees a pioneering research program, reports on discoveries about how fructose impacts the body—and directly connects the American obesity epidemic to a frightening escalation in our fructose consumption.It comes as no surprise that the sugar is found in processed foods like candy, baked goods, canned foods, and frozen meals in the form of high-fructose corn syrup, but it is also hidden in less obvious foods like peanut butter, egg products, and soups. Many fruits and vegetables contain high levels of it naturally. Dr. Johnson shows how to cut way back on the sweetener by making effective substitutions. The daily meal plans included here contain no more than 25 grams of fructose, one-quarter of the amount the average American now ingests.Rather than the low-carb approach of so many recent diets, Dr. Johnson recommends a much easier to enjoy and stick to formula: 50% carbs, 25% fat, and 25% protein. The immediate benefit of this diet is to help anyone shed excess weight. The additional benefits are even more impressive—reduced risk for such serious health problems as high blood pressure, elevated blood fats, and insulin resistance, conditions directly linked to heart disease, diabetes, kidney disease, and stroke.

     In this masterful account of the 1995 Ebola outbreak in Zaire, Garrett, now the Senior Fellow for Global Health at the Council on Foreign Relations, shows how superstition and fear, compounded by a lack of resources, education, and clearheaded government planning have plagued our response to Ebola. In an extensive new introduction, Garrett forcefully argues that learning from past outbreaks is the key to solving the Ebola crisis of 2014. In her account of the 1995 Zaire outbreak, first published in her bestselling book Betrayal of Trust, Garrett takes readers through the epidemic's course-beginning with the Kikwit villager who first contracted it from an animal encounter while chopping wood for charcoal deep in the forest. As she documents the outbreak in riveting detail, Garrett shows why our trust in world governments to protect people's health has been irrevocably broken. She details the international community's engagement in the epidemic's aftermath: a pattern of response and abandonment, urgency that devolves into amnesia. Ebola: Story of an Outbreak is essential reading for anyone who wants to comprehend Ebola, one of mankind's most mysterious, malicious scourges. Garrett has issued a powerful call for governments, citizens, and the disease-fighting agencies of the wealthy world to take action.
