The morning after CERN announces the discovery of the Higgs particle, three young physicists sit down with Nobel prizewinners George Smoot and Martinus Veltman to digest the news. The students see it as another success for the standard model of particle physics. But Veltman, who helped to shape this model, is cynical. Moreover, Veltman contends that there is no such thing as dark matter. See how the shocked students and Smoot respond to Veltman's scepticism.

In the next 100 years or so, we will run out of fossil fuels. In this film, Nobel laureates Mario Molina and Robert Laughlin challenge three young physicists to think seriously about the energy endgame and their children's futures. Molina believes we can solve the looming crisis through international collaboration -- as happened after he showed that CFCs were damaging the ozone layer. Laughlin disagrees. He wants engineering solutions, and says nations will go to war unless we find them.

This video gives an overview of some of the key papers in the Nature archive. From the development of nuclear fission to the cloning and birth of Dolly the sheep, Nature has continually published some of the most influential work in scientific history.

The Nobel laureates and young researchers who met in Lindau this summer came from all over the world, but they had one thing in common: physics. We filmed five debates on issues that matter to the current generation of researchers. Is dark matter real? How can we solve the looming energy crisis? How is physics perceived by the public? Watch the trailer for a taste of the discussions and disagreements that emerged.

The films will be published between 19 September and 10 October 2012

Ever since a monk called Mendel started breeding pea plants we've been learning about our genomes. In 1953, Watson, Crick and Franklin described the structure of the molecule that makes up our genomes: the DNA double helix. Then, in 2001, scientists wrote down the entire 3-billion letter code contained in the average human genome. Now they're trying to interpret that code; to work out how it's used to make different types of cells and different people. The ENCODE project, as it's called, is the latest chapter in the story of you.

Camelia-Lucia Cimpianu is trying to decide between a career as a researcher or a practising doctor. In this film, she seeks advice from Nobel Laureate Ferid Murad who faced the same dilemma as a medical student in the 1960s. Murad chose the bench, and he subsequently discovered that a gas called nitric oxide (NO) acts as a signalling molecule in the cardiovascular system. It turns out that NO plays a role in many diseases — and possibly in the head trauma cases that Camelia studies.

The colorful Amazonian butterfly Heliconius Numata increases its odds of survival by mimicking the wing patterns of other closely-related species. Researchers led by French scientist Mathieu Joron show that supergenes are behind its varied wing patterns. Read the original research here (preview): http://www.nature.com/nature/journal/...

RNA interference (RNAi) is an important process, used by many different organisms to regulate the activity of genes. This animation explains how RNAi works and introduces the two main players: small interfering RNAs (siRNAs) and microRNAs (miRNAs). We take you on an audio-visual journey, diving into a cell to show how genes are transcribed to make messenger RNA (mRNA) and how RNAi can silence specific mRNAs to stop them from making proteins. The animation is based on the latest research, to give you an up-to-date view.

On 5 August NASA successfully landed its rover, Curiosity, on Mars. Since landing, the rover has captured some striking images of the red planet. In this video, NASA scientists John Grotzinger and Joy Crisp talk about what we've seen so far, and what we might encounter when Curiosity drives towards Mount Sharp -- where we hope to find signs of water.
