The origin of the turtle shell: Mystery solved

A team of RIKEN researchers has finally solved the riddle of how the turtle shell originated. By observing the development of different animal species and confirming their results with fossil analysis and genomic data, researchers ...

Electron slow motion: Ion physics on the femtosecond scale

How do different materials react to the impact of ions? This is a question that plays an important role in many areas of research—for example, in nuclear fusion research, when the walls of the fusion reactor are bombarded ...

Let's store solar and wind energy – by using compressed air

Electricity generated by fossil fuels is increasingly unsustainable and a shift towards renewable energy – principally from the sun and wind – is vital. Renewable generation is already less expensive per unit than its ...

Solar flares: What does it take to be X-class?

Solar flares are giant explosions on the sun that send energy, light and high speed particles into space. These flares are often associated with solar magnetic storms known as coronal mass ejections (CMEs). The number of ...

Understanding climate tipping points

As the planet warms, many parts of the Earth system are undergoing large-scale changes. Ice sheets are shrinking, sea levels are rising and coral reefs are dying off.
