Right now researchers are hunting for extra-terrestrial life on several fronts. To find out just how close we might be to a breakthrough, astrophysicist Dr Graham Phillips visits telescopes, swims among the stromatolites on the remote West Australian coastline, and chats with scientists from around the world

Off Australia's northeast coast lies a wonder of the world, a living structure so big it can be seen from space, more intricate and complex than any city, and so diverse it hosts a third of all fish species in Australia. The Great Barrier Reef as we know it -- 8,000 years old and home to thousands of marine species -- is dying in our lifetime.

A group of world-renowned scientists are on a quest to uncover the secrets of the most significant day in our planet's history: the day that killed the dinosaurs. 66 million years ago an asteroid the size of London hit the planet in the modern-day Gulf of Mexico. Now, as co-leaders of an expedition to drill deep into the Chicxulub asteroid impact crater, Geologists Sean Gulick and Jo Morgan have set out to answer how this resulted in the extinction of dinosaurs.

The Cholesterol Question is a hard-hitting investigation into the heart of cholesterol’s controversial journey, from essential biological substance to Public Enemy Number One and possible rehab. It’s a villain that’s simple to understand, easy to implicate and, we thought, easy to medicate. But it’s a story almost stranger than fiction. At Stanford University, Dr. Christopher Gardner reveals the debatable science behind our assault on dietary fat and cholesterol – a massive intervention that many believe only made us fatter and sicker.
Beginning with the first eight weeks when a single cell, no bigger than a speck of dust, transforms into a human foetus, the most sophisticated organism on the planet. This period is the most perilous time in the womb and determines the layout of body organs, when our heart makes its first beat, and when the length of our lives could be decided.

Seventy years ago, when the coldest thing in your house was a pantry, most of the food we ate was harvested, sent straight to the shops and would have been on our plates before it started to go off. However, the advent of the home freezer and advances in various preservation techniques changed all of that and now we’re used to eating what we want, when we want, regardless of the time of year when the food is actually grown. So how do they keep the food for so long? And does the quality stay the same?
Panorama looks at the breakthrough that could change the lives of everyone and everything on the planet. Gene editing is revolutionising medical research and could deliver new treatments - even cures for a host of diseases. It also gives scientists control over evolution, allowing genetic changes to be forced through species. But some are worried about letting the gene genie out of the bottle.
Stem cells found in the bone marrow are crucial for our health because they are needed to become new blood cells that sustain and protect our bodies. But when the transformation goes wrong, harmful mutations can cause the cells to start replicating without control -- a type of cancer known as leukemia. Danilo Allegra and Dania Puggioni explain how this happens and how certain treatments provide hope for those suffering from the disease.
