| Researchers at Lund University said Tuesday their find backs up claims by teams in Russia and the United States a decade ago that had remained unverified until now. The Swedish scientists say they conducted experiments which allowed them to detect the 
	'fingerprint' of the short-lived but super-heavy element that's been dubbed ununpentium. The name, which refers to the element's 115th place in the periodic table, is only provisional. The element will likely get a new name if the discovery is formally approved by experts from the International Union of Pure and Applied Physics and Chemistry. Well-known chemical elements include carbon, silicon and iron. |
