New kids on the block

Back in January, I reported that the periodic table would be getting an update because four new elements were discovered - finally, the new names have been penciled in. Nihonium, moscovium, tennessine, and oganesson will grace the blocks assigned to atomic numbers 113, 115, 117, and 118, said the International Union of Pure and Applied Chemistry (IUPAC) today. Nihonium, discovered by a Japanese team, means “the land of the rising sun,” while moscovium and tennessine are named after places near the labs where they were discovered (Moscow and Tennessee, of course). And oganesson recognizes the work of Russian chemist Yuri Oganessian. By tradition, the right to suggest a name for an element is granted to its discoverer, although IUPAC has ...

Time to update the science textbooks

The periodic table has been given four new elements, changing one of science’s most fundamental pieces of knowledge. Elements 113, 115, 117 and 118 will now be added to the table’s seventh row and make it complete, after they were verified by the International Union of Pure and Applied Chemistry on December 30 th. The new elements were discovered by team from Japan, Russia and the USA, who will all get to name their own new elements. All of the four new admissions are man-made. The super-heavy elements are created by shoving lighter nuclei into each other and are found in the radioactive decay - which only exists for a tiny fraction of a second before they decay into other elements. The elements have been worked on since at least 2004, when st ...

Scientists identified sulfur, nitrogen, hydrogen, oxygen, phosphorus and carbon -- some of the key chemical ingredients for life -- in the powder Curiosity drilled out of a sedimentary rock near an ancient stream bed in Gale Crater on the Red Planet last month.

Beautiful Reed Flute Cave
|
view preview
This is Reed Flute Cave, in the Guangxi region of China. This natural limestone formation is over 180 million years old and contains inscriptions written in ink, which have been dated to as far back as 792 AD in the Tang Dynasty. The cave was named after the type of reed growing outside, which can be made into musical flutes.

Proof that money does grow on trees
|
view preview
Well, okay GOLD. Apparently, gold grows on eucalyptus trees. Researchers discovered that the trees are acting as a hydraulic pump, extracting gold from the soil and moving it to their leaves and branches. The ‘nuggets’ are about one-fifth the diameter of human hair, but the leaves may be used in combination with other tools to develop better exploration techniques.
