Three regions — North America, North & West Europe, and East & Southeast Asia — produced 91% of the overall 2014 output (WFC) in the Nature Index.

There is scope for improvement with the volume and quality of research in this region, but some innovative programmes for study abroad might improve future publications.

Research is dominated by heavyweights Australia and New Zealand but shifts in science policy on both sides of the Tasman Sea are creating uncertainty about the future.

Public health demands might drive advances in research, but scientists, working against the odds, must also strive to publish in global journals.

Strong spending and recruitment keep countries in this region near the top of the world's output in the Index, and scientists from universities collaborate more with their neighbours.

Social change and economic stagnation create challenges for this region's biggest countries, but some of the smaller ones are shining.

International projects — including an advanced particle accelerator and educational facilities — bolster this region's focus on chemistry and physical sciences.

India's dominance continues in this region, but its future funding is tenuous, while neighbouring smaller countries face more fundamental obstacles to scientific success.

While remaining strong in chemistry and physical sciences, buoyed by China's growing contribution, the region embarks on collaborations that could extend its reach.

This region includes lots of strong institutions — from government agencies to universities — but curtailed funding raises concerns for the future.

The Nature Index 2015 Asia-Pacific reveals strong overall results from the traditional science leaders in this region. In addition, some smaller countries excel in specific areas.

Space-travel success inspires the growing science and technology community, but financial difficulties create obstacles and industry is being called upon to take up more of the financial burden.

Reforms are underway to make best use of tight research budgets, but it remains unclear if changes will address Japan's many challenges or further destabilize the deeply unsettled science powerhouse.
