In the past two decades, our understanding of the navigational and physiological feats that enable birds to cross immense oceans, fly above the highest mountains, or remain in unbroken flight for months at a stretch has exploded. What we've learned of these key migrations is nothing short of extraordinary. This breathtaking work of nature writing also introduces listeners to those scientists, researchers, and bird lovers trying to preserve global migratory patterns in the face of climate change and other environmental challenges.

Math has a reputation for being inaccessible. People think that it requires a special gift or that comprehension is a matter of genes. Yet, the greatest mathematicians throughout history, from Rene Descartes to Alexander Grothendieck, have insisted that this is not the case.

How did we end up here, masters of scientific insight, purveyors of ever more powerful technologies, astride the burning planet that created us, and now responsible for cleaning up the mess and determining the future direction of all of life? And what do we do about it? Technology is Dead is a book that attempts to answer both of those questions. It is a book of both challenge and hope, written for those who are able or willing to lead us out of our global predicament.

Each day we are exposed to a myriad of natural and human-made chemicals in our food, drinking water, air, soil, at home or at the workplace-pesticide residues, food additives, drugs, household products-but how can we gauge the human health risk posed by these chemicals? Should we believe the somber headlines that depict a serious threat for humans and the environment, or should we follow the reassuring voices of others who claim that the angst is totally unfounded?

The world needs to turn away from fossil fuels and use clean, renewable sources of energy as soon as we can. Failure to do so will cause catastrophic climate damage sooner than you might think, leading to loss of biodiversity and economic and political instability. But all is not lost! We still have time to save the planet without resorting to 'miracle' technologies. We need to wave goodbye to outdated technologies, such as natural gas and carbon capture, and repurpose the technologies that we already have at our disposal.

Lives of Weeds explores the tangled history of weeds and their relationship to humans. Through eight interwoven stories, John Cardina offers a fresh perspective on how these tenacious plants came about, why they are both inevitable and essential, and how their ecological success is ensured by determined efforts to eradicate them. Linking botany, history, ecology, and evolutionary biology to the social dimensions of humanity's ancient struggle with feral flora, Cardina shows how weeds have shaped - and are shaped by - the way we live in the natural world.

An accessible and engaging account of the mind and its connection to the brain.
