Does manganese inhaled from the shower represent a public health threat
A new analysis based on animal studies suggests that showering in manganese-contaminated water for a decade or more could have permanent effects on the nervous system. The damage may occur even at levels of manganese considered safe by the Environmental Protection Agency, according to researchers... view more (2005-07-01)
A Novel Mechanism of Manganese-Induced Neurological Dysfunction Discovered
For decades, scientists have known that chronic exposure to high concentrations of the metal manganese can cause movement abnormalities resembling symptoms of Parkinson's disease, but apparently without the same neuron damage characteristic of Parkinson's patients. view more (2006-08-29)
MIT powers up new battery for hybrid cars
Researchers at MIT have developed a new type of lithium battery that could become a cheaper alternative to the batteries that now power hybrid electric cars. view more (2006-02-17)
Tuberculosis drug may cure Parkinson's-like illness
Researchers have discovered that a drug used to treat tuberculosis apparently cures patients of a Parkinson's-like illness suffered by thousands of mineworkers, welders and others exposed to high levels of the metal manganese. view more (2006-06-07)
Mayo Clinic case series illuminates connection between welding, brain damage
A Mayo Clinic case series analysis has pinpointed for the first time syndromes associated with toxic damage to the brain and nervous system from manganese fumes generated during welding. view more (2005-06-09)
Earliest Stage of Planet Formation Dated
UC Davis researchers have dated the earliest step in the formation of the solar system -- when microscopic interstellar dust coalesced into mountain-sized chunks of rock -- to 4,568 million years ago, within a range of about 2,080,000 years. view more (2007-12-20)
Scientists build 'magnetic semiconductors' one atom at a time
In a stride that could hasten the development of computer chips that both calculate and store data, a team of Princeton scientists has turned semiconductors into magnets by the precise placement of metal atoms within a material from which chips are made. view more (2006-07-28)
Scientists Image 'Magnetic Semiconductors' On The Nanoscale
In a first-of-its-kind achievement, scientists at the University of Iowa, the University of Illinois at Urbana-Champaign and Princeton University have directly imaged the magnetic interactions between two magnetic atoms less than one nanometer apart (one billionth of a meter) and embedded in a... view more (2006-07-27)
New 'layered-layered' materials for rechargeable lithium batteries
Researchers at the Department of Energy's Argonne National Laboratory have developed a new approach to increasing the capacity and stability of rechargeable lithium-ion batteries. view more (2007-05-08)
Researchers uncover protection mechanism of radiation-resistant bacterium
Recent discoveries by researchers at the Uniformed Services University of the Health Sciences (USU) could lead to new avenues of exploration for radioprotection in diverse settings. Michael J. Daly, Ph.D., an associate professor in USU's Department of Pathology, and his colleagues have uncovered... view more (2007-03-21)
Monash team learns from nature to split water
An international team of researchers led by Monash University has used chemicals found in plants to replicate a key process in photosynthesis paving the way to a new approach that uses sunlight to split water into hydrogen and oxygen. view more (2008-08-18)
Ohio University Researchers Create Improved Magnetic-Semiconductor Sandwich
Researchers at Ohio University have created an improved magnetic semiconductor that solves a problem spintronics scientists have been investigating for years. view more (2006-10-03)
Scientists learn structure of enzyme in unusual virus
Biologists have determined the three-dimensional structure of an unusual viral enzyme that is required in the assembly of new viruses. view more (2007-09-18)
Transition Metal Selenites (Mn, Co, Ni, Fe, Cu, Zn and Cd)
The work involved a multidisciplinary task, undertaking the study of phases of mineralogical and physico-chemical interest. Selenites were synthesised, given that they are a new field and likely to present original physical properties. view more (2005-09-30)
New disease-fighting nanoparticles look like miniature pastries
Ultra-miniature bialy-shaped particles - called nanobialys because they resemble tiny versions of the flat, onion-topped rolls popular in New York City - could soon be carrying medicinal compounds through patients' bloodstreams to tumors or atherosclerotic plaques. view more (2008-07-30)
DO NOT HIDE FROM RAIN UNDER A FIRTREE
Russian scientists have found out that industrial contamination of atmosphere has more impact on flora and soil under the trees and the trees as such than on the space between the crowns. The study has been funded by the Russian Foundation for Basic Research and the President~s grant. We normally... view more (2000-12-15)
Extracting Metal from the Sea â€" the Environmentally Friendly Way
A novel method that uses bacteria to mine valuable minerals from the ocean has been developed. Nodules collected from the Indian Ocean seabed can be treated to extract scarce land-based minerals in an environmentally sound way, says research published in the Journal of Chemical Technology and... view more (2004-04-02)
Scientists reveal how a novel ceramic achieves directional conduction
An international team led by UCL (University College London) scientists at the London Centre for Nanotechnology has unravelled the properties of a novel ceramic material that could help pave the way for new designs of electronic devices and applications. view more (2006-04-20)
BSE - A Post Industrial Disease?
Ahead of the Commons debate on BSE due to be held next week, an alternative hypothesis about the origin and behaviour of BSE and vCJD is posed in the latest issue of the SCI publication Chemistry & Industry. Dr David Brown of the University of Cambridge suggests that prion diseases are... view more (2001-02-13)
Research casts doubt on controversial scientific theory
Scientists at the University of Sheffield have cast doubt on the validity of the controversial theory of biological cold fusion, the principle sometimes used to lend credence to the practice of selling silicon tablets to strengthen bones, on the assumption that the body will turn the silicon into... view more (2003-05-07)
Anti-aging hormone reduces reactive oxygen species
Scientists recently discovered an anti-aging hormone called Klotho. Now, a new study shows that this protein acts by increasing the cell's ability to detoxify harmful reactive oxygen species. view more (2005-11-04)
Risk of Parkinson's disease increases with pesticide exposure and head trauma
Exposure to pesticides and traumatic head injury may have a causative role in Parkinson's disease, according to a study published online ahead of print in the journal Occupational and Environmental Medicine. view more (2007-05-30)
Calcite, a filter for water-borne arsenic?
An experiment at the Institut Laue-Langevin raises great hopes. view more (2005-02-10)
Breakthrough for the computer of tomorrow?
For the first time a material now exists that is not only a semiconductor but also exhibits exploitable magnetic properties at room temperature. Researchers at the Royal Institute of Technology (KTH) in Stockholm, Sweden, have taken the lead in an international race to find the technology of... view more (2003-09-25)
Modified electron microscope identifies atoms
A new electron microscope recently installed in Cornell's Duffield Hall is enabling scientists for the first time to form images that uniquely identify individual atoms in a crystal and see how those atoms bond to one another. And in living color. view more (2008-02-22)
