Almost six million Americans—about one in every ten people over the age of sixty-five—have Alzheimer’s disease or related dementias, and this number is projected to more than double by 2050. What is it like to live with and amid this increasingly prevalent condition—an affliction that some fear more than death? In My Father’s Brain, the distinguished physician and author Sandeep Jauhar sets his father’s descent into Alzheimer’s alongside his own journey toward understanding this disease and how it might best be coped with, if not cured.

Jacob Fugger lived in Germany at the turn of the 16th century, the grandson of a peasant. By the time he died, his fortune amounted to nearly 2 percent of European GDP. Not even John D. Rockefeller had that kind of wealth. Most people become rich by spotting opportunities, pioneering new technologies, or besting opponents in negotiations. Fugger did all that, but he had an extra quality that allowed him to rise even higher: nerve.

Solar energy, once a niche application for a limited market, has become the cheapest and fastest-growing power source on earth. What's more, its potential is nearly limitless. But in Taming the Sun, energy expert Varun Sivaram warns that the world is not yet equipped to harness erratic sunshine to meet most of its energy needs. And if solar's current surge peters out, prospects for replacing fossil fuels and averting catastrophic climate change will dim.

In AI Superpowers, Kai-fu Lee argues powerfully that because of these unprecedented developments in AI, dramatic changes will be happening much sooner than many of us expected. Indeed, as the US-Sino AI competition begins to heat up, Lee urges the US and China to both accept and to embrace the great responsibilities that come with significant technological power.

Life is getting better at an accelerating rate. Food availability, income, and life span are up; disease, child mortality, and violence are down all across the globe. Though the world is far from perfect, necessities and luxuries alike are getting cheaper; population growth is slowing; Africa is following Asia out of poverty; the Internet, the mobile phone, and container shipping are enriching people's lives as never before.

How do you define the good life? For many, success is measured not by health and happiness but by financial wealth. But such a worldview overlooks the important things in life: personal contentment, family time, spirituality, and the health of the planet and those living on it. A preoccupation with money and possessions is not only unhealthy, it can also drain the true joy from life. In recent years, millions have watched their American Dreams go up in smoke.

In 1942, a team at the University of Chicago achieved what no one had before: a nuclear chain reaction. At the forefront of this breakthrough stood Enrico Fermi. Straddling the ages of classical physics and quantum mechanics, equally at ease with theory and experiment, Fermi truly was the last man who knew everything - at least about physics. But he was also a complex figure who was a part of both the Italian Fascist Party and the Manhattan Project, and a less-than-ideal father and husband who nevertheless remained one of history's greatest mentors.
