The Incredible Science of Temperature episode 2: Helen Czerski explores the narrow band of temperature that has led to life on Earth and shows how all living creatures depend on temperature for its survival. She reveals how life began in a dramatic place where hot meets cold, and how every single living creature on Earth depends on temperature for its survival. She uncovers the extraordinary natural engineering that animals have evolved to keep their bodies at the right temperature. And she witnesses the remarkable surgery that’s using temperature to push the human body to the very brink of life. Â In

The Incredible Science of Temperature episode 1 – Frozen Solid : Dr Helen Czerski discovers how cold has shaped our planet, and how pushing the limits of cold has unlocked new technologies, from superconductors to quantum computing. Everything around us – from the tiniest insect on Earth to the most distant stars of the cosmos – exists somewhere on a vast scale from cold to hot. In this series, physicist Dr Helen Czerski explores the extraordinary science of temperature. She unlocks the extremes of the temperature scale, from absolute zero to searing heat of stars – and reveals how

The Wonder of Animals – Great Apes: Chris Packham explores the evolution of the great ape’s brain to reveal how different parts have been adapted over time by its anatomy, ingenuity and sociability, culminating in one of the most complex brains on the planet. Chris examines how the ability to use two hands asymmetrically sets the great ape apart from other tool-using animals and how social living is linked to the evolution of the amygdala in both humans and our ape cousins. New research reveals how bonobos’ peace-loving reputation may have developed through a similar domestication process to

The Wonder of Animals – Dolphins: Chris Packham explores the success of the most widespread of marine mammals, the dolphin. Contrary to their amiable reputation, they are in fact ruthless predators. They hunt using a combination of specialised anatomy and complex communication, requiring a big brain. Chris explains the inner workings of dolphin echolocation, reveals how a pod uses body movements to communicate the location of food and explores the strategies used by orcas during a hunt. Series in which Chris Packham uses groundbreaking science and brand-new behaviour to delve deep beneath the skin and discover the unique features that

The Wonder of Animals – Bats: Bats have colonised remote corners of the planet to become one of most widespread mammals on earth. Chris Packham explores their incredible anatomy, physiology and senses to understand what enables them to thrive in some surprising places. Tiny hairs on their wings give them a detailed air-flow map during flight, heat sensors on the nose of vampire bats means they can sense the most blood-rich areas of a prey’s body and iron oxide particles in the bat brain may act as a compass allowing them to find the most direct route back

The Wonder of Animals – Birds of Prey: Chris Packham explores what enables birds of prey to rule the aerial roost. Their ability to dominate their fellow birds in terms of strength, manoeuvrability and phenomenal speed is down to a combination of anatomical and physiological adaptations. Chris explains the internal workings of the bald eagle’s ratchet talons and how sharp eyes and a gyroscopic head enable the goshawk to keep its sight firmly fixed on both its prey and its surroundings as it tears through the undergrowth. New research reveals how pop-up feathers on the peregrine falcon’s back

The Wonder of Animals – Crocodiles: Chris Packham explores what lies beneath a crocodile’s hard exterior to discover the secret to its 250-million-year history. It may look like a relic from a prehistoric world, but the crocodile boasts one of the most sophisticated physiologies on the planet. By following all stages of a crocodile hunt, from the warm-up to the ambush and the kill, Chris reveals how their extraordinary circulatory system enables them to hold their breath underwater for over an hour, how exceptionally sensitive skin detects their prey through water from over 20m away and how antibacterial blood means

The Wonder of Animals – Foxes: Across the planet carnivores are struggling to compete in a world with a rocketing human population, but one predator is bucking the trend – the fox. Its numbers are increasing and its geographical range expanding. Chris Packham explores the secrets to its success – its senses, its intelligence and its flexibility. New research reveals how its slit pupils enable it to hunt in the bright desert day; how it may be using the Earth’s magnetic field to determine the location of prey during a pounce; and how regular exposure to rotting food

The Wonder of Animals – Penguins: Chris Packham explores what makes animal groups successful. He looks at how the penguin’s legs, wings and body shape have allowed it to adapt to a range of environments. At first sight, penguins seem ill-suited to their environment – rotund abdomens, stubby little legs and stiff wings appear to make the going tough. But in fact it is these very traits that enable this bird to thrive. Chris explores details of the penguin’s anatomy, using new scientific research to reveal how its legs, wings and body shape have allowed it to conquer

The Wonder of Animals – Bears: Bears can live in practically every habitat on Earth, from tropical jungles to the Arctic Ocean. Wherever they are found, they are capable of surviving extreme conditions and extracting the highest-quality food. Detailing the latest research, Chris Packham explores the specialised adaptations that have enabled bears to thrive, including how a polar bear’s hollow fur allows it to feed throughout the gruelling Arctic winter, whilst a state of ‘walking hibernation’ sees it through the summer months. Series in which Chris Packham uses groundbreaking science and brand-new behaviour to delve deep beneath the
