First Biological Evidence Of Ancient Supernova
2013-05-09 09:20:27

John P. Millis, PhD for redOrbit.com — Your Universe Online In the early Universe the only elements capable of forming were hydrogen and helium. All subsequent atoms are created by massive stars: the lighter members by nuclear fusion in their cores, with much of the rest created during supernovae as atoms are collided at incredible energies leading to nucleosynthesis. Some of the elements produced have long half-lives, sticking around to lay the foundation for new stars, planets and...

Magnetic Toys Can Be Life-Threatening For Kids
2013-03-12 14:18:24

Lee Rannals for redOrbit.com - Your Universe Online According to a study published in the Canadian Medical Association Journal (CMAJ), there is a growing danger of children ingesting magnets that can lead to life-threatening health complications. Kids swallowing magnets is probably not a new phenomenon, but some of today´s magnets are an average of 10 to 20 times stronger than previous ones, creating new dangers. In the past, magnet ingestion was treated with a wait-and-see...

Improving The Process To Recycle Rare-earth Materials
2012-10-25 10:07:46

Recycling keeps paper, plastics, and even jeans out of landfills. Could recycling rare-earth magnets do the same? Perhaps, if the recycling process can be improved. Scientists at the U.S. Department of Energy´s (DOE) Ames Laboratory are working to more effectively remove the neodymium, a rare earth element, from the mix of other materials in a magnet. Initial results show recycled materials maintain the properties that make rare-earth magnets useful. The current rare earth...

A rare kind of mineral which scientists hope could be used to remove toxic metals and radioactive species from the environment played a similar, crucial role early in Earth's history. Research carried out by an international team of leading biogeochemists suggests for the first time that 'green rust' was likely widespread in ancient oceans and may have played a vital role in the creation of our early atmosphere. Led by Newcastle University, UK, the study shows that during the...

Cobalt is a chemical element in the periodic table that has the symbol Co and atomic number 27. Notable characteristics Cobalt is a hard ferromagnetic silver-white element. The Curie temperature is of 1388 K with 1.6~1.7 Bohr magnetons per atom. It is frequently associated with nickel, and both are characteristic ingredients of meteoric iron. Mammals require small amounts of cobalt salts. Cobalt-60, an artificially produced radioactive isotope of cobalt, is an important radioactive...

Limonite Limonite is a ferric hydrate of varying composition, the generic formula is frequently written as FeO(OH)·nH2O, although this is not entirely accurate as Limonite often contains a varying amount of oxide compared to hydroxide. Together with hematite, it is mined as ore for the production of iron. Limonite is heavy and yellowish-brown. It is not a true mineral, however, but a mixture of similar hydrated iron oxide minerals, mostly Goethite. Limonite forms mostly in or near...

Magnetite is a magnetic mineral form of both iron(II) oxide and iron(III) oxide or (iron(II,III) oxide), with chemical formula Fe3O4, one of several iron oxides and a member of the spinel group. Magnetite is the most magnetic of all the minerals on Earth, and these magnetic properties led to lodestone being used as an early form of magnetic compass. Small grains of magnetite occur in almost all igneous rocks and metamorphic rocks as well as many sedimentary rocks. Magnetite is a...
