Beyond element 118: the next row of the periodic table. Chemistry World

Four new elements have just been added to the periodic table completing the table’s seventh row. But despite elements 113, 115 and 118 all being discovered in the early 2000s and 117 in 2010, there’s still no sign of elements 119 and beyond. Why has no one claimed to have created one of these new superheavyweights and when will chemists be able to start an eighth row on the periodic table? Read more…

Nuclear fusion gets boost from private-sector startups. Science News

The lab where a company called General Fusion is trying to spark an energy revolution looks like a cross between a hardware store and a mad scientist’s lair. Bins full of electrical gadgets are piled high against the walls. Capacitors recycled from a bygone experiment are stacked up like bottles in wine racks. Ten-foot-high contraptions bristle with tangled wires and shiny plumbing. Read more…

The Milky Way’s clean and tidy galactic neighbor. Science Daily

Many galaxies are chock-full of dust, while others have occasional dark streaks of opaque cosmic soot swirling in amongst their gas and stars. However, the subject of this new image, snapped with the OmegaCAM camera on ESO’s VLT Survey Telescope in Chile, is unusual — the small galaxy, named IC 1613, is a veritable clean freak! IC 1613 contains very little cosmic dust, allowing astronomers to explore its contents with great clarity. Read more…
