Temperature contributed to our evolution - our upright walking, our loss of fur, and our big brains - and now continues to affect our lives in unexpected ways, and the link from a warm mug to our emotions is anything but straightforward. Studies have shown, for example, that a chilly deliberation room can predispose a jury to convict and that a cold day can make us more likely to buy a house. Our mind-body connection works the other way, too: Thinking about friendly or caring people can make us feel warmer.

The environment is collapsing at a rapid rate, and in increasingly unpredictable ways. Everyone knows that this is happening, and yet the only politics that is emerging to tackle it are coming from the increasingly nativist far-right. How should the left respond? In Planet on Fire, two rising stars of the British left lay down a set of proposals for a fundamental re-shaping of the global economy and offer a road map for tackling climate breakdown.

In May 1967, internationally renowned activist Fannie Lou Hamer purchased 40 acres of land in the Mississippi Delta, launching the Freedom Farms Cooperative (FFC). Life on the cooperative farm presented an alternative to the second wave of northern migration by African Americans - an opportunity to stay in the South, live off the land, and create a healthy community. Freedom Farmers expands the historical narrative of the Black freedom struggle to embrace the work, roles, and contributions of Southern Black farmers and the organizations they formed.

On a moonless night in January 1991, a dozen US aircraft appeared in the skies over Baghdad. To the Iraqi air defenses, the planes seemed to come from nowhere. Each aircraft was more than 60 feet in length and with a wingspan of 40 feet, yet its radar footprint was the size of a ball bearing. Here was the first extensive combat application of Stealth technology. And it was devastating.

Are the secrets of the universe written in words - or is it all about the digits? K. C. Cole follows up her paean to the power of physics, Sympathetic Vibrations, with this engaging and accessible guide to the might and majesty of mathematics. The Universe and the Teacup uses relatable examples and humorous prose to demonstrate math's ability to "translate the complexity of the world into manageable patterns".

Master Beekeeper Frank Mortimer invites listeners on an eye-opening journey into the secret world of bees and the singular world of his fellow beekeepers. With a swarm of offbeat characters and fascinating facts (did that bee just waggle or festoon?), Frank the Bee Man delivers an informative, funny, and galvanizing book about the symbiotic relationship between flower and bee, and bee and the beekeepers who are determined to protect the existence of one of the most beguiling and invaluable creatures on earth.

Biogeography is the study of geographic variation in all characteristics of life - ranging from genetic, morphological, and behavioral variation among regional populations of a species, to geographic trends in diversity of entire communities across our planet's surface. From the ancient hunters and gatherers to the earliest naturalists, Charles Darwin, Alfred Russel Wallace, and scientists today, the search for patterns in life has provided insights that proved invaluable for understanding the natural world.

Enzymes are the astonishing tiny molecular machines that make life possible. Each one of these small proteins speeds up a single chemical reaction inside a living organism many millionfold. Working together, teams of enzymes carry out all the processes that collectively we recognize as life, from making DNA to digesting food. This Very Short Introduction explains the why and the how of speeding up these reactions - catalysis - before going on to reveal how we have evolved these catalysts of such extraordinary power and exquisite selectivity.

Parker describes the discovery of tetrahydocannbinol (THC), the main psychoactive component of cannabis, and the further discovery of cannabinoid receptors in the brain. She explains that the brain produces chemicals similar to THC, which act on the same receptors as THC, and shows that the endocannabinoid system is involved in all aspects of brain functioning.

Superconductivity is one of the most exciting areas of research in physics today. Outlining the history of its discovery and the race to understand its many mysterious and counterintuitive phenomena, this Very Short Introduction audiobook explains in accessible terms the theories that have been developed and how they have influenced other areas of science, including the Higgs boson of particle physics and ideas about the early universe.

If you move at high speed, time slows down, space squashes up, and you get heavier. Travel fast enough and you could weigh as much as a jumbo jet, be flattened thinner than a CD without feeling a thing - and live forever! As for the angles of a triangle, they do not always have to add up to 180 degrees. And then, of course, there are black holes. These are but a few of the extraordinary consequences of Einstein's theory of relativity.

A century ago, mountain lions were vilified as a threat to livestock and hunted to the verge of extinction. Its recovery has led to an unexpected conundrum: Do more mountain lions mean they're a threat to humans and domestic animals? Or, are mountain lions still in need of our help and protection as their habitat dwindles? Mountain lion biologist and expert Mark Elbroch welcomes these tough questions. He dismisses long-held myths about mountain lions and uses groundbreaking science to uncover important new information about their social habits.

Human travel into space is an enormously expensive and unforgiving endeavor. So why go? In this accessible and authoritative book, astrophysicist Martin Elvis argues that the answer is the asteroid exploration, for the strong motives of love, fear, and greed. Elvis explains how each motive can be satisfied, and how they help one another. From the origins of life, to "space billiards," and space sports, Elvis looks at how asteroids may be used in the not-so-distant future.

In November 2018, the world was shocked to learn that two babies had been born in China with DNA edited while they were embryos - as dramatic a development in genetics as the cloning of Dolly the sheep was in 1996. In this book, Hank Greely, a leading authority on law and genetics, tells the fascinating story of this human experiment and its consequences. Greely explains what Chinese scientist He Jiankui did, how he did it, and how the public and other scientists learned about and reacted to this unprecedented genetic intervention.

With well over 200 episodes and a dozen seasons, The Big Bang Theory is one of America's favorite television series, bringing a new class of character to mainstream television: the science nerd.
