This two-dimensional crystal keeps playing a dominant role in physics and materials science.

Diluted magnetic semiconductors and oxides are interesting for fundamental science and applications even without room-temperature ferromagnetism.

The discovery of C₆₀ — a molecular allotrope of carbon — marked a pivotal moment in the field of nanotechnology. Twenty-five years on, carbon remains the element of choice for simple but functional materials.

Mexico is a country rich with natural resources and an educated workforce. Yet its scientific output remains below its potential. In this focus issue we try to highlight some of Mexico's structural problems.

The work by Roberto Car and Michele Parrinello on ab initio molecular dynamics published 25 years ago has had a huge impact on fundamental science and applications in a wide range of fields.

The United Kingdom's tough budget for science may force researchers to pick winners and losers. But can it work?

The large investments in research and education made in recent years have provided Brazilian scientists with the conditions to achieve scientific excellence.

If Europe wants to be at the forefront of scientific research it is essential for governments to find the means to improve collaboration and the distribution of innovation across Europe.

The first demonstration of the laser has not only led to a myriad of commercial applications, but fifty years on basic research continues to rejuvenate the fundamental physics of the laser.

Japan's new frugal political leadership serves as a threat and an opportunity for Japanese scientists.

Light-concentration effects in photonic nanostructures, reviewed in this issue, promise new applications ranging from tumour therapy to catalysis and enhanced solar cells.

The opportunity of reaching a strong agreement on carbon emission cuts must not be missed again.

Nobel prizes for applied research provide recognition for innovations with profound impact, fully in tune with the intentions of Alfred Nobel.
