Modern Biology

Nessa Carey’s The Epigenetics Revolution looks at how modern biology is rewriting our understanding of genetics, disease and inheritance....

In 2017, author Shanna Swan and her team of researchers completed a major study. They found that over the past four decades, sperm levels among men in Western countries have dropped by more than 50 percent. They came to this conclusion after examining 185 studies involving close to 45,000 healthy men. The result sent shockwaves around the globe - but the story didn’t end there.

When the downtrodden animals of Manor Farm overthrow their master Mr Jones and take over the farm themselves, they imagine it is the beginning of a life of freedom and equality. But gradually a cunning, ruthless élite among them, masterminded by the pigs Napoleon and Snowball, starts to take control. Soon the other animals discover that they are not all as equal as they thought, and find themselves hopelessly ensnared as one form of tyranny is replaced with another.

In Unfit for Purpose, biologist and broadcaster Adam Hart explores the mismatch between our fundamental biology and the modern world we have created. In each chapter Adam reveals the many ways in which biological adaptations that evolved to help us survive and thrive now work against us. For example, in the modern world stress is a killer, but how did 'fight or flight' instincts turn from life-savers to life-takers? Obesity might be a disease now, but is it really just a troublesome side-effect of our complex evolutionary past?

From the familiar to the improbable, the gross to the endearing, The Modern Bestiary is a compendium of curious creatures. It includes both animals that have made headlines and those you've probably never heard of, such as skin-eating caecilians, harp sponges or zombie worms—also known as bone-eating snot flowers. Arranged by elements (Earth, Water, Air), The Modern Bestiary contains well-known species told from unexpected new angles (rats that drive cars; fish that communicate by passing wind), as well as stranger and lesser-known creatures.

Human beings have astonishing genetic vulnerabilities. More than half of us will die from complex diseases that trace directly to those vulnerabilities, and the modern world we've created places us at unprecedented risk from them. In It Takes a Genome, Greg Gibson posits a revolutionary new hypothesis: Our genome is out of equilibrium, both with itself and its environment. Simply put, our genes aren't coping well with modern culture.
