Some 10,000 US researchers have signed a statement protesting about political interference in the scientific process.

The statement, which includes the backing of 52 Nobel Laureates, demands a restoration of scientific integrity in government policy.

According to the American Union of Concerned Scientists, data is being misrepresented for political reasons.

It claims scientists working for federal agencies have been asked to change data to fit policy initiatives.

The Union has released an "A to Z" guide that it says documents dozens of recent allegations involving censorship and political interference in federal science, covering issues ranging from global warming to sex education.
