Nature is pleased to name physicist Steven Chu, Nobel laureate and the US Secretary of Energy, as its Newsmaker of the Year.
Steven Chu made his name — and earned his Nobel prize — by developing an ingenious laser technique for capturing and studying atoms. He is an extraordinary experimentalist who loves the challenges of the lab. But five years ago, he embraced a much bigger challenge when he took the helm at Lawrence Berkeley National Laboratory in California and dedicated it to clean-energy research. Chu was sworn in as secretary of the US Department of Energy this January, and is now charged with transforming the way the world's largest economy powers itself. That is why Nature has selected Chu as its Newsmaker of the Year.
Chu has already had a significant impact. From his position near the top of President Barack Obama's administration, he has helped make the case that the United States must commit to reducing its greenhouse-gas emissions, not only to save the planet but also to ensure that the country will be able to compete with China, India and Europe in the emerging green economy.
