The recently discovered element 117 has been officially named "tennessine" in recognition of Tennessee’s contributions to its discovery, including the efforts of the Department of Energy's Oak Ridge National Laboratory and its Tennessee collaborators at Vanderbilt University and the University of Tennessee. "The presence of tennessine on the Periodic Table is an affirmation of our state's standing in the international scientific community, including the facilities ORNL provides to that community as well as the knowledge and expertise of the laboratory's scientists and technicians," ORNL Director Thom Mason said.

Chemistry teachers recently had to update their classroom decor, with the announcement that scientists have confirmed the discovery of four new elements on the periodic table. The as-yet unnamed elements 113, 115, 117 and 118 filled in the remaining gaps at the bottom of the famous chart-a roadmap of matter's building blocks that has successfully guided chemists for nearly a century and a half. The official confirmation, granted by the International Union of Pure and Applied Chemistry (IUPAC), was years in the making, as these superheavy elements are highly unstable and tough to create. But scientists had strong reason to...

Most of the world is dependent on China to supply rare earths as key raw materials used in many of the latest technologies from military hardware to electric cars, but China's Ministry of Commerce is warning that its massive supply of rare earths could be exhausted in just 15 - 20 years. The current rate of production and global consumption is just too large for China. Bloomberg: China, controller of more than 90 percent of production of the materials used in cell phones and radar, cut its export quotas by 72 percent for the second half and reduced output, spurring...

A little square that has been left blank on the periodic table for all these years might finally be filled in. A team of American and Russian scientists have just reported the synthesis of a brand new element–element 117. Says study coauthor Dawn Shaughnessy: “For a chemist, it’s so fundamentally cool” to fill a square in that table [The New York Times]. If other scientists confirm the discovery, the still-unnamed element will take its place between elements 116 and 118, both of which have already been tracked down. A paper about element 117 will soon be published in Physical Review...

BERKELEY, CA Discovery of two new "superheavy" elements has been announced by scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory. Element 120 and its immediate decay product, element 121, were discovered at Berkeley Lab's 88-Inch Cyclotron by bombarding targets of lead with an intense beam of high-energy krypton ions. Although both new elements almost instantly decay into other elements, the sequence of decay events is consistent with theories that have long predicted an "island of stability" for nuclei with approximately 187 protons and 199 neutrons. "We jumped over a sea of instability onto an island of stability...

US scientists have confirmed the discovery of element number 114, first made over a decade ago by a team in Russia. By smashing a high energy beam of calcium-48 ions into a plutonium-242 target, the US team managed to detect two nuclei of element 114, which is predicted by some to be bordering the so-called 'island of stability' for superheavy atoms.Yuri Oganessian and his team at Dubna, Russia, were the first to claim to have created nuclei of element 114 - but any such claim has to be thoroughly verified and the experiments repeated independently before the element can be considered for admission...

BERLIN (Reuters) – A new, superheavy chemical element numbered 112 will soon be officially included in the periodic table, German researchers said. A team in the southwest German city of Darmstadt first produced 112 in 1996 by firing charged zinc atoms through a 120-meter-long particle accelerator to hit a lead target. "The new element is approximately 277 times heavier than hydrogen, making it the heaviest element in the periodic table," the scientists at the GSI Helmholtz Center for Heavy Ion Research said in a statement late on Wednesday.

The Heaviest Element Known to Science Lawrence Livermore Laboratories has discovered the heaviest element yet known to science. The new element, Governmentium (Gv), has one neutron, 25 assistant neutrons, 88 deputy neutrons, and 198 assistant deputy neutrons, giving it an atomic mass of 312. These 312 particles are held together by forces called morons, which are surrounded by vast quantities of lepton-like particles called peons.z Since Governmentium has no electrons, it is inert; however, it can be detected, because it impedes every reaction with which it comes into contact. A tiny amount of Governmentium can cause a reaction that would...

LIVERMORE, Calif., Oct. 16 (UPI) -- U.S. and Russian scientists say they have discovered the newest superheavy element -- element 118. The researchers from the U.S. Department of Energy's Lawrence Livermore National Laboratory and from the Joint Institute for Nuclear Research in Russia made the announcement Monday. In experiments conducted at the JINR U400 cyclotron from February-June 2005, the researchers said they observed atomic decay patterns, or chains, that establish the existence of element 118. In these decay chains, previously observed element 116 is produced via the alpha decay of element 118. Element 118 is expected to be a noble...

Jason Dangel4th Brigade Combat Team,4th Infantry Division BAGHDAD — The 4th Infantry Division’s Infrastructure Coordination Element, donated about $2 million worth of excavating and clean-up equipment to essential services departments from the Rasheed and Karradah Districts in Baghdad Sunday. The equipment, purchased from funds seized from former Iraqi dictator Saddam Hussein, will now be used to help restore quality of life for citizens in these Baghdad districts. Each district received a backhoe/loader, a pickup truck, and a...

Loss, WAISRC Explanation: The remnants of nuclear reactors nearly two billion years old were found in the 1970s in Africa. These reactors are thought to have occurred naturally. No natural reactors exist today, as the relative density of fissionable uranium has now decayed below that needed for a sustainable reaction. Pictured above is Fossil Reactor...
