The story of life, from the first primitive cells to the plants and animals that now live around us. David Attenborough examines the uses and advantages of birds' unique possession - the feather. Man has yet to invent anything that, weight for weight, is as strong as the feather. Feathers are insulators, they provide the surface of the most perfect aerofoils known - bird's wings

Mammals have proved to be one of the most adaptable products of evolution. David Attenborough looks at their evolution from reptiles 200 million years ago. This remarkable transition involved the development of mechanisms for regulating body temperature, for allowing the young to develop in the womb and for suckling newborns.

David Attenborough brings us the universal story that unites each of us with every animal on the planet, the story of the greatest of all adventures - the journey through life. In the first episode, animals overcome their first great hurdle - surviving infancy.

In the journey towards adulthood, a moment comes for all animals when they must strike out on their own. With their parents absent they must learn to survive in a dangerous world. At this stage of life every small success may mean the difference between life and death.

Animals must find somewhere to live - a place that provides the necessities of life, shelter from the elements and a refuge from enemies.

Animals must try to gain a position of power in their worlds. The most powerful have best access to food and water, and they are also the most attractive to the opposite sex.

David Attenborough explores the courtship displays of flame bowerbirds and pufferfish.

In this final episode, animals attempt to rear their offspring.

Life Story takes us on the greatest of all adventures - the journey through life.

Two-part series in which Professor Jim Al-Khalili shows how, by uncovering its secrets, scientists have used light to reveal almost everything we know about the universe.

Professor Jim Al-Khalili tells the story of how we went from thinking we were close to a complete understanding of the universe to realising we had seen almost none of it. Today, our best estimate is that more than 99 per cent of the cosmos is hidden in the dark, invisible to our telescopes and beyond our comprehension.

The scientists behind the scenes tell the extraordinary story of what really happened in the run up to the first lockdown, when ministers claimed to be 'following the science'.

Geologist Iain Stewart retraces the steps of a band of maverick pioneers who made ground-breaking discoveries in the landscape of Scotland about how our planet works.

Iain Stewart follows in the footsteps of the founding father of geology, James Hutton. This Scottish rogue was a profound and original thinker who, 250 years ago, overturned ancient beliefs about how and when the world was formed. His ideas clashed with those of the most eminent scientist of his day. Lord Kelvin was determined to prove Hutton wrong.

Iain finds out how gung-ho geologist Edward Bailey discovered Scotland was once home to super volcanoes. And how unsung hero Arthur Holmes solved the mystery of what makes continents move across the surface of the globe.

In the final episode, Iain finds out about daredevil scientist Louis Agassiz, who first imagined the world had been gripped by an ice age. Plus, the story of humble janitor James Croll, who used the planets to work out the natural rhythms of the earth\'s climate.

Metamorphosis seems like the ultimate evolutionary magic trick, the amazing transformation of one creature into a totally different being: one life, two bodies.

For 70 years we've waged war against harmful bacteria using antibiotics. But bacteria are fighting back and today more and more bacterial infections are becoming resistant to antibiotics. Drug-resistant superbugs are spreading; not just MRSA - also TB, pneumonia, e-coli.
