Peter Suciu for RedOrbit.com On Tuesday, Planetary Resources announced its plan to mine Near-Earth Asteroids (NEAs), paving the way for mankind's reach beyond the Earth. This would include mining for raw minerals, ranging from water - which would be required for any future human colonization — and two precious metals such as gold and platinum. “Many of the scarce metals and minerals on Earth are in near-infinite quantities in space,” said Dr. Peter Diamandis,...

Rice University lab develops starfruit-shaped nanorods for medical imaging, chemical sensing They look like fruit, and indeed the nanoscale stars of new research at Rice University have tasty implications for medical imaging and chemical sensing. Starfruit-shaped gold nanorods synthesized by chemist Eugene Zubarev and Leonid Vigderman, a graduate student in his lab at Rice´s BioScience Research Collaborative, could nourish applications that rely on surface-enhanced Raman...

Hydrogen fuel cells, like those found in some "green" vehicles, have a lot of promise as an alternative fuel source, but making them practical on a large scale requires them to be more efficient and cost effective. A research team from the University of Central Florida may have found a way around both hurdles. The majority of hydrogen fuel cells use catalysts made of a rare and expensive metal — platinum. There are few alternatives because most elements can't endure the fuel...

Molybdenite is a mineral of molybdenum disulfide, MoS2. Similar in appearance and feel to graphite, molybdenite has a lubricating effect which is produced by its structure of close-spaced parallel cleavage planes. Finely powdered MoS2, with particle sizes in the 1-100 µm range, is a common technical dry lubricant. It is also often mixed into various oils or greases, which allows mechanisms so lubricated to run less noisy and to keep running for a while longer even if most of the oil should...

Platinum is a chemical element in the periodic table that has the symbol Pt and atomic number 78. A heavy, malleable, ductile, precious, gray-white transition metal, platinum is resistant to corrosion and occurs in some nickel and copper ores along with some native deposits. Platinum is used in jewelry, laboratory equipment, electrical contacts, dentistry, and anti-pollution devices in automobiles. Notable characteristics The metal is a beautiful silvery-white when pure, and malleable...

Silver is a chemical element in the periodic table that has the symbol Ag (from the traditional abbreviation from the Latin Argentum) and atomic number 47. A soft white lustrous transition metal, silver has the highest electrical and thermal conductivity of any metal and occurs in minerals and in free form. This metal is used in coins, jewelry, tableware, and photography. Notable characteristics Silver is a very ductile and malleable (slightly harder than gold) univalent coinage metal...

Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
