Science Uses X-Rays To Unlock Mystery Of Picasso Paint
2013-02-07 14:27:31

Michael Harper for redOrbit.com — Your Universe Online The best way to win any decades-long debate is science, science, and more science. If, for example, you´re able to hire a team of technicians to operate a powerful X-Ray to prove your point, there´s almost no way you´ll lose. Such is the case with a long-standing debate over which type of paint Picasso used in his works. Art scholars have been arguing for many years over the theory that the cubist painter used...

Two of the most widely used nanoparticles (NPs) accumulate in soybeans – second only to corn as a key food crop in the United States – in ways previously shown to have the potential to adversely affect the crop yields and nutritional quality, a new study has found. It appears in the journal ACS Nano. Jorge L. Gardea-Torresdey and colleagues cite rapid increases in commercial and industrial uses of NPs, the building blocks of a nanotechnology industry projected to put $1...

Metals contained in nanoparticles can enter into the food chain Scientists have, for the first time, traced the nanoparticles taken up from the soil by crop plants and analyzed the chemical states of their metallic elements. Zinc was shown to dissolve and accumulate throughout the plants, whereas the element cerium did not dissolve into plant tissue. The results contribute to the controversial debate on plant toxicity of nanoparticles and whether engineered nanoparticles can enter into the...

Taking The Sting Out Of Box Jellyfish Stings
2012-12-13 12:04:54

Brett Smith for redOrbit.com - Your Universe Online Box jellyfish are known to lurk in the waters off the coast of Hawaii and a pair of researchers from the island state have found a treatment that takes some of the sting out of the invertebrate´s deadly venom, according to their study in the open access journal PLOS ONE. Angel Yanagihara and Ralph Shohet from the University of Hawaii have shown that zinc can mitigate the effects of the jellyfish´s venom, which act on a victim...

Scientists Probe Canadian Sulfide Ore To Confirm Microbial Activity In Seawater 2.7 Billion Years Ago
2012-12-10 20:42:04

McGill University An analysis of sulfide ore deposits from one of the world's richest base-metal mines confirms that oxygen levels were extremely low on Earth 2.7 billion years ago, but also shows that microbes were actively feeding on sulfate in the ocean and influencing seawater chemistry during that geological time period. The research, reported by a team of Canadian and U.S. scientists in Nature Geoscience, provides new insight into how ancient metal-ore deposits can be used to...

U.S. Department of Agriculture (USDA) research confirms that the time-tested practice of amending crop soils with manure also can help restore soils on damaged post-mining landscapes. Thousands of acres of land with little or no vegetation, once mined for lead and zinc, remain throughout an area of southwestern Missouri, southeastern Kansas, and northeastern Oklahoma. The mining activities also left behind a legacy of lead-contaminated acidic soils, toxic smelter sites, and large...

Aurichalcite is a mineral, usually found as a secondary mineral in copper and zinc deposits. Its chemical formula is (Zn,Cu)5(CO3)2(OH)6. The name probably originates from the Greek oreichalchos meaning "mountain copper".

Copper is a chemical element in the periodic table that has the symbol Cu and atomic number 29. Notable characteristics Copper is a reddish-coloured metal, with a high electrical and thermal conductivity (among pure metals at room temperature, only silver has a higher electrical conductivity). Copper may well be the oldest metal in use, as copper artifacts dating to 8700 BC have been found. Besides being part of various ores, copper can be found in the metallic form (i.e. native copper)...

Smithsonite, or zinc spar, is zinc carbonate ZnCO3, a mineral ore of zinc. Historically, smithsonite was identified with hemimorphite before it was realised that they were two distinct minerals. The two minerals are very similar in appearance and the term calamine has been used for both, leading to some confusion.

Zinc is a chemical element in the periodic table that has the symbol Zn and atomic number 30. Notable characteristics Zinc is a moderately reactive metal that will combine with oxygen and other non-metals, and will react with dilute acids to release hydrogen. The one common oxidation state of zinc is +2. Applications Zinc is the fourth most common metal in use, trailing only iron, aluminium, and copper in annual production. - Zinc is used to galvanize metals such as steel to...
