"We have grown an atom-thin, ordered, two-dimensional multi-phase film in situ through germanium molecular beam epitaxy using a gold (111) surface as a substrate. (...)

After the successful synthesis of silicene in 2012, which was followed by a surge of studies on elemental, novel two-dimensional (2D) materials beyond graphene, a daunting quest was to obtain germanene, the germanium-based analogue of graphene, already predicted to possibly exist in 2009. Although its fully hydrogenated form, germanane, was fabricated using a wet chemistry method in 2013, germanene has remained elusive. Here we show compelling experimental and theoretical evidence of its synthesis by dry epitaxial growth on a gold (111) surface. (...)"

Francois Englert and Peter W. Higgs won the 2013 Nobel Prize For Physics on Tuesday for their research into the Higgs boson particle, nicknamed the "God particle."

Des chercheurs du laboratoire national Brookhaven ont mesuré les performances d’un transistor en oxyde de germanium et titane utilisant une couche isolante high-K en dioxyde de hafnium, selon Phys.org.

Nineteen elements on the periodic table — including gold, cadmium, arsenic and aluminum — are getting their atomic weights adjusted.
