Sensitive new quantitive methods could be used to detect small signs of increased tremor and impaired motor skills caused by exposure to certain metals, and to follow up the treatment of neurological disorders, reveals a thesis from the University of Gothenburg, Sweden. "The aim was to investigate whether quantitative measurement methods, in other words sensitive computer-based methods, could be used to detect small changes in tremor or other motor functions resulting from exposure to low...

(Ivanhoe Newswire) -- Ever heard the saying: you are what you eat? Now, Canadian researchers may be saying: you are what you drink. They found children who drink water with more manganese have lower IQs. Researchers examined 362 children who lived in Quebec and were between ages 6 and 13. These kids all lived in homes that were supplied by groundwater. Investigators measured the concentration of manganese, iron, copper, lead, zinc, arsenic, magnesium and calcium in their tap water. Manganese...

An accidental discovery in a laboratory at Oregon State University has apparently solved a quest that over thousands of years has absorbed the energies of ancient Egyptians, the Han dynasty in China, Mayan cultures and more "“ the creation of a near-perfect blue pigment. Through much of recorded human history, people around the world have sought inorganic compounds that could be used to paint things blue, often with limited success. Most had environmental or durability issues. Cobalt...

That palm tree magnet commemorating your last vacation is programmed for a simple function "“ to stick to your refrigerator. Similarly, semiconductors are programmed to convey bits of information small and large, processing information on your computer or cell phone.Scientists are working to coax those semiconductors to be more than conveyers, to actually perform some functions like magnets, such as data recording and electronic control. So far most of those effects could only be...

Hypoxia, or lack of oxygen, in bottom waters is a well known environmental problem. New research at the University of Gothenburg, Sweden adds to the list of ill effects: hypoxia leads to increased levels of manganese, which damages the immune response in marine animals.Water eutrophication and the resulting hypoxia is an ever-current issue, not least in connection with summer algal blooms. A more recently acknowledged problem is that hypoxia, which occurs when algae is broken down, increases...

A U.S. researcher says manganese in the environment may correlate with both decreases and increases in cancer deaths. The study, published online by Biological Trace Element Research, says airborne manganese was associated at the county level with a 14 percent decrease in total cancer deaths. The study also finds a 43 percent decrease in breast cancer deaths and a 22 percent decrease in lung cancer deaths. However, there was up to a 28 percent increase in colon cancer deaths and a 26...

U.S. scientists say they have discovered marine microorganisms use manganese and iron to convert methane into carbon dioxide. The Pennsylvania State University researchers said their finding is important because carbon dioxide can produce compounds that sequester carbon in the ocean, reducing the amount of CO2 in the Earth's atmosphere. That process had previously been thought to be dependent on compounds containing sulfur. Graduate student Emily Beal, principal author of the study, said the...

In the first ecological study of its kind in the world, a Wake Forest University Baptist Medical Center researcher has uncovered the unique finding that groundwater and airborne manganese in North Carolina correlates with cancer mortality at the county level.The study, titled, "Environmental Manganese and Cancer Mortality Rates by County in North Carolina: An Ecological Study," was published online last month by Biological Trace Element Research. Lead researcher John Spangler, M.D., professor...

Aluminum (or aluminium) is a soft, lightweight, silvery metal. It is an element in the boron group on the periodic table of elements, with the symbol Al and atomic number 13. On the earth's crust, aluminum is the most abundant metal, and the third most abundant of all elements on the earth's crust, after oxygen and silicon. It accounts for 8% of the weight of the Earth's solid surface. Because aluminum is a highly reactive metal, it doesn't occur in nature in a pure form. Aluminum forms a...

Manganese is a chemical element in the periodic table that has the symbol Mn and atomic number 25. Notable characteristics Manganese is a gray-white metal, resembling iron. It is a hard metal and is very brittle, fusible with difficulty, but easily oxidized. Manganese metal is ferromagnetic only after special treatment. The most common oxidation states of manganese are +2, +3, +4, +6 and +7, though oxidation states from +1 to +7 are observed. Mn2+ often competes with Mg2+ in...
