Some black holes grow much faster than their galaxies

Nearly every galaxy has a supermassive black hole. The few that don't have had theirs ejected during a galactic collision. That's because galaxies and their black holes have formed hand in hand. There is still some debate as to whether galaxies formed around the seeds of supermassive black holes or the other way around, but there is plenty of evidence to support the idea that the two evolve together.

Saving the Oceans - Part One

Saving the Ocean looks at the impact of climate change, overfishing and pollution - and examines the scientific solutions to some of those issues. In the first programme Joel Werner visits Kiribati – an isolated Pacific island group threatened by rising sea levels. They are also facing a range of more immediate problems - a high human population and a shortage of land puts pressure on natural resources. Joel meets the scientists working to keep the population afloat on these tiny coral atolls. He finds out about how this island group is threatened by sea level rise and changing weather patterns - and how in some cases, poor sea defence management is making the erosion of the islands worse.(Image: Low tide reveals the detritus of 50,000 people on South Tarawa, Kiribati, BBC copyright)

Fixing Nitrogen

Today, 3.5 billion people are alive because of a single chemical process. The Haber-Bosch process takes nitrogen from the air and makes ammonia, from which synthetic fertilizers allow farmers to feed our massive population. Ammonia is a source of highly reactive nitrogen, suitable not just for fertilizer, but also as an ingredient in bomb making and thousands of other applications. We make around 100 million tonnes of ammonia annually - and spread most of it on our fields. But this is a very inefficient way to use what amounts to 1-2% of the planet's energy needs. Only around 20% of fertilizer made ends up in our food. Professor Andrea Sella explores some of the alternative ways we might make fertilizer. Vegetables such as peas and beans, allow certain cells in their roots to become infected by a specific type of bacteria. In return, these bacteria provide them with their own fertilizer. Could we infect the plants we want to grow for food – such as cereals – in a similar way to cut down the climatic and environmental impact of Haber-Bosch?
