FEATURE : US research funding key to abundance of Nobels


Cash-rich US researchers have again dominated this year’s Nobel awards, but it seems identifying the nationality of laureates is not an exact science, and change may be on the way.

On the face of things, the US would top an Olympic-style medals table of Nobel prize wins. Eleven of this year’s 13 laureates are citizens of the US, winning five of the six Nobel awards up for grabs.

Even US President Barack Obama pocketed a prize.

Since the end of World War II, the US has scooped up 89 Nobel awards for medicine, 74 for physics, 58 for chemistry and dozens more for economics, peace and literature, beating its closest contenders in Britain, France and Germany.

Unsurprisingly then, the rest of the world is left to ask how the US does it. The answer may be, in part, “It doesn’t.”

A look at the curricula vitae of this year’s Nobel science winners — which make up four of the six awards — shows a complex patchwork of academics criss-crossing the globe to reach the top their profession.

“You have to ask where they studied,” said Sharon Bertsch McGrayne, an American who has written a book profiling female Nobel laureates.

“Many of our scientists have done their post-docs in Europe,” she said, pointing to high migration levels among top scientists.

This year’s crop of laureates shows just how difficult it is to determine the nationality of globe-trotting laureates, especially based on Nobel citations which use citizenship at the time of award.

Charles Kao (高錕), who shared this year’s prize for physics for his work in developing fiber optics, is a US citizen, but he was born in Shanghai, educated in London and now lives in Hong Kong.

Venkatraman Ramakrishnan, who shared the prize for chemistry, was born in India, works in Britain, but has US citizenship.

Australian-born Elizabeth Blackburn is also a US citizen, but studied at the universities of Melbourne and Cambridge before a post doctoral degree at Yale.

Willard Boyle, who won also shared the physics prize for his work on semiconductors, is Canadian and studied at Montreal’s McGill University, but now has US citizenship.

Obama — despite claims by his most vociferous critics — is among the most unquestionably American of the laureates.

Research from Britain’s University of Warwick, published last January, shows scientific migration is common, and vastly beneficial to the US.

“Nearly half of the world’s most-cited physicists work outside their country of birth,” the study said.

A survey of 158 of the most highly cited physicists showed systematic migration to nations with large research and development spending, most notably the US.

“At birth, 29.7 percent of physicists are in the USA. This increases to 43.4 percent at first degree, to 55.1 percent at PhD, and to 67.1 percent presently,” the report said. “In 1987-2006, for example, five out of fourteen of all UK-educated laureates had moved to the USA by the time they won the Nobel prize.”

Still, the US can claim to have forged the institutes and universities that attract top-flight researchers for award-winning research.

US State Department figures show that every year the US issues more than 35,000 visas for exceptional scientists and others who flock to well-funded institutes.

But the real key to US Nobel dominance, according to Roger Geiger, a professor of education at Pennsylvania State University, is cash — particularly the massive influx of cash to the US education system after World War II.
