New data revealed from the Cassini mission to Saturn suggests the planets’ tiny moons are made of the same material as its enigmatic rings. Material from the rings is building up around the circumference of the moons - in effect making them grow.

Looking into the far reaches of deep space scientists are narrowing down the number of planets they think could be habitable. New developments with space and ground telescopes will give us a chance to examine the chemical signature of earth like exoplanets for tell-tale signs of life.

Ancient barnacles may have a role to play in predicting the impact of climate change on migratory whale species. Fossilised barnacles species known to live on whales give clues to ancient migratory routes and how these evolved as the earth’s climate changed.

Swapping dairy milk for a plant-based milk is a growing trend that promises environmental benefits. But what is the best milk considering both our health and the planet’s? We dig into the research and find that if the whole world were willing to swap dairy for soy, we would free up a land mass the size of Australia and reduce greenhouse gas emissions dramatically. So in theory the planet would be happier – but can we live without it?
