Nov. 17, 2010 Antihydrogen trapped for first time Physicists working at the European Organization for Nuclear Research (CERN) in Geneva, Switzerland, have succeeded in trapping antihydrogen – the antimatter equivalent of the hydrogen atom – a milestone that could soon lead to experiments on a form of matter that disappeared mysteriously shortly after the birth of the universe 14 billion years ago. The first artificially produced low energy antihydrogen atoms – consisting of a positron, or antimatter electron, orbiting an antiproton nucleus – were created at CERN in 2002, but until now the atoms have struck normal matter and annihilated in a flash of gamma-rays within microseconds of creation.
IBM Microscope Gives High-Speed Look at Atoms – NYTimes.com I.B.M. scientists have modified a scanning-tunneling microscope, making it possible to observe dynamic processes inside individual atoms on a time scale one million times faster than has previously been possible.
Big news in the world of the periodic table: Element 117 (ununseptium) has been synthesized! The known periodic table is now complete with this heaviest halogen. Next up: ununnovium (119)?! The periodic table below has been updated to include the new element.
