Researchers at Brookhaven National Laboratory have devised a method to combine chemical treatment with bacteria to remove cadmium from contaminated soil, leaving insoluble cadmium sulfide in place. This technique could be less costly than traditional methods and has potential for treating other metals like arsenic and cobalt.
Researchers develop a new method to fabricate optoelectronic devices using Fullerenes and positively charged polymers, generating a current from a negatively charged Fullerene and a positively charged polymer. This process creates a photovoltaic device without the use of toxic solvents or expensive instruments, under ambient conditions.
A recent study found that older women with high natural estrogen levels are less likely to suffer cognitive decline. The researchers measured free estrogen and loosely bound forms of the hormone, finding a 70% lower risk of cognitive decline in those with the highest levels.
Chemists at the University of Georgia have developed a new approach to synthesizing key components of Heparin, a widely used anti-coagulant. This method could lead to novel ways to fight disease or improve human health by understanding the structure-function relationships of Heparin.
Researchers discovered that nicotine uses a mechanism responsible for learning and memory to enhance neural connections and induce an enduring memory trace. This finding suggests new targets for drugs designed to block nicotine craving.
Agricultural copper transport and toxicity in runoff from tomato fields to estuaries remains a significant concern, with sedimentation basins offering only partial solutions. Researchers found that even with reduced copper concentrations, bioavailable forms still pose harm to aquatic life.
A national team of over 150 researchers will study air pollution in the Houston region, combining data from six research aircraft and 60 ground-based monitoring stations. The goal is to identify cost-effective ways to control pollutants and protect public health.
Researchers discovered a striking similarity between proteins involved in early stages of Alzheimer's disease and mad cow disease using computer modeling. The study suggests a common molecular mechanism underlying the initiation stages of these neurodegenerative diseases, potentially leading to new preventive drug targets.
A team of six Brown University professors will explore the human brain's function using tiny electronic structures, potentially enabling computers to mimic human capabilities. The five-year grant aims to develop nanotechnology that can stimulate and record brain cells.
OHSU researchers have successfully recorded individual nerve cell transmissions for the first time, revealing how synapses enable cells to communicate. The study provides new insights into the mechanisms of neural communication and has potential implications for understanding neurological and mental diseases.
