For many decades, researchers tried to formulate theories"”such as the String Theory"”to account for flaws in the Standard Model of the element, whose spherical design could not account for gravity. Jurjen Van der Wal, a structural and mechanical engineer who understands structural design, conceived a universally fitting foundation and drastically new approach to physics in 'Decoding the Periodic Table.' Newport Beach, CA (PRWEB) May 19, 2011 Jurjen van der Wal's scientific...

Last fall, EARTH caught up with geochemistry grad student Jeremy Jacquot as he was about to embark on the first U.S.-led GEOTRACES cruise across the Atlantic, where he and 32 researchers were hoping to measure and track concentrations of various trace elements and isotopes. This month, in "Tracking Trace Elements and Isotopes in the Oceans," we follow up with Jacquot as he details the highs, lows and initial findings from the cruise, which was unfortunately cut short due to a ship...

Exploring an 'island of inversion,' physicists find new clues to element synthesis in supernovaeElements heavier than iron come into being only in powerful stellar explosions, supernovae. During nuclear reactions all kinds of short-lived atomic nuclei are formed, including more stable combinations "“ the so-called magic numbers "“ predicted by theory. Yet here, too, there are exceptions: the islands of inversion. Headed by physicists from the Excellence Cluster Universe at the...

Researchers from around the world compile more reliable data that will help science and industry For the first time in history, a change will be made to the atomic weights of some elements listed on the Periodic table of the chemical elements posted on walls of chemistry classrooms and on the inside covers of chemistry textbooks worldwide. The new table, outlined in a report released this month, will express atomic weights of 10 elements - hydrogen, lithium, boron, carbon, nitrogen, oxygen,...

One-atom-thick sheet offers new microelectronic possibilities Rice University researchers have found a way to stitch graphene and hexagonal boron nitride (h-BN) into a two-dimensional quilt that offers new paths of exploration for materials scientists. The technique has implications for application of graphene materials in microelectronics that scale well below the limitations of silicon determined by Moore's Law. New research from the lab of Pulickel Ajayan, Rice's Benjamin M. and Mary...

The name proposed by GSI for the heaviest chemical element has been officially endorsed The heaviest recognized chemical element with the atomic number 112 was discovered at the GSI Helmholtzzentrum fr Schwerionenforschung and "“ since February 19, 2010 "“ officially carries the name copernicium and the chemical symbol "Cn". The name was approved and officially announced today by the international union for chemistry IUPAC*. The name "Copernicium" honors scientist and astronomer...

An exotic form of carbon has been found to have an extra large nucleus, dwarfing even the nuclei of much heavier elements like copper and zinc, in experiments performed in a particle accelerator in Japan. The discovery is reported in the current issue of Physical Review Letters and highlighted with a Viewpoint by Kirby Kemper and Paul Cottle of Florida State University in the February 8 issue of Physics. Carbon-22, which has a nucleus comprised of 16 neutrons and 6 protons, is the heaviest...

"For almost 10 years we have tried to find out what distinguishes stars with planetary systems from their barren cousins," says Garik Israelian, lead author of a paper appearing this week in the journal Nature. "We have now found that the amount of lithium in Sun-like stars depends on whether or not they have planets." Low levels of this chemical element have been noticed for decades in the Sun, as compared to other solar-like stars, and astronomers have been unable to explain the anomaly....

Isotopes, the atomic clues used to solve crimes, date ancient artifacts and identify chemicalsWhether it's the summer grass that tickles your feet or the red Bordeaux smacking on your palette, nearly every part of the world around you carries special chemical markers. These markers, called isotopes, can tell scientists where the molecules that compose a substance are from, where they traveled, and what happened to them along the way. But doing these analyses has been complex and costly. Now,...

With help from newly developed equipment designed and built at Michigan State University, MSU researchers have been able to make first-of-its-kind measurements of several rare nuclei, one of which has been termed a "holy grail" of experimental nuclear physics. The discoveries, made at MSU's National Superconducting Cyclotron Laboratory using an isotope purification device, will help to refine theoretical models about how elements are created in the cosmos. Until now, this was beyond the...

Sulfur (or Sulphur; see spelling below) is the chemical element in the periodic table that has the symbol S and atomic number 16. It is an abundant, tasteless, odorless, multivalent non-metal. Sulfur, in its native form, is a yellow crystaline solid. In nature, it can be found as the pure element or as sulfide and sulfate minerals. It is an essential element for life and is found in several amino acids. Its commercial uses are primarily in fertilizers but it is also widely used in gunpowder,...

  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
