In households across the world, pets are at the heart of family life. They share our homes, but how well do we really know them? In this series we'll dig deep into our pets' inner lives to discover the secrets they've kept hidden until now. From spectacular feats of communication to extreme athleticism, extraordinary intelligence and incredible super senses.
We'll meet remarkable pets from across the globe whose owners have harnessed their hidden skills and shared them with the world and will use groundbreaking technology to reveal how amazing their brains and bodies really are.
In the first episode, a base-jumping border collie, a bopping cockatoo, and racing rats show that animal intelligence can get a big boost in the right enriched environment.

Will explore the strategy, deception and feats of engineering plants use to thrive in the changing weather of different seasons. In the face of conditions ranging from ice and snow to raging fires, survival is often a question of perfect timing - particularly when contending with intense competition and surprising predators.
In this episode, David Attenborough travels to Finland to show one of the most extreme examples of seasonal plant life in the Arctic Circle. He also travels to California to see how climate change is affecting giant sequoias. These ancient trees like all other seasonal plants depend on the predictability of the seasons and our current changing climate threatens their survival.

Law enforcement faces scrutiny as Americans demand justice after police violence claims multiple Black lives in Cleveland. The film examines the case in Cleveland where police officers shot at unarmed suspects in a car 137 times. Timothy Russell and Malissa Williams were the victims.
While looking at policing standards within the city of Cleveland, '137 Shots' also examines the shooting of 12-year old Tamir Rice by Cleveland police officers. This film is an extremely tough thing to watch, but necessary in order to bring about awareness for change.

The film explores the revolutionary gene-editing tech now giving humankind the freedom to redraw the blueprint of biological life itself. We investigate not only the tremendous potential the technology holds, whether in the fight to eliminate diseases or in transforming agriculture to adapt to unprecedented climate extremes, but also probe the inherent risks involved and the potential for widespread abuse, dangers that could take our future down a very dark, dystopian path.

Physicist Dr Helen Czerski journeys to the extremes of the temperature scale, where the everyday laws of physics break down and a new world of scientific possibilities begins. In the first part, Frozen Solid, Helen reveals how cold has shaped the world around us and why frozen doesn't mean what you think it does. She meets scientists pushing temperature to the limits of cold, driving technologies such as superconductors.
The second part, A Temperature for Life, explores the narrow band of temperature that has led to life on Earth, how life began where hot meets cold and how every living creature depends on temperature for survival. In the last part, Playing with Fire, Helen Czerski explores the science of heat. She reveals how heat is the hidden energy contained within matter with the power to transform it from state to state.

Inside the world-renowned physics laboratory Fermilab, a team of scientists are constructing an audacious experiment to hunt for a mysterious new ‘ghost’ neutrino. If they find it, this could transform our understanding of the nature and fabric of our universe. The problem is, these tiny particles are almost impossible to detect.
Elsewhere, physicists conduct experiments in some of the most extreme environments on the planet: from deep mine shafts in South Dakota to vast ice fields at the South Pole. In these unlikely places supersized neutrino detectors hope to unlock the universe’s deepest secrets. Could neutrinos overturn the most precise theory of particle physics that humans have ever written down? Could they even be a link to a hidden realm of new particles that permeate the cosmos – so called dark matter? Scientists at Fermilab are edging towards the truth.
