Researchers at Purdue University have been working on phytoremediation, a process that uses plants to collect heavy metals and radioactive waste from polluted sites. By understanding how plants take up and store toxic metals, they aim to develop metal-mining plants that can clean up contaminated soil and water.
Researchers at Stanford University have identified two separate clusters of neurons in the hippocampus involved in encoding and retrieving memories. These findings provide insight into the neural basis of memory and could lead to better treatments for Alzheimer's disease and other neurological disorders.
Researchers at Columbia University and IBM used X-rays to measure changes in atomic structure as electric current flowed through tiny wires. They found large stresses of up to 50,000 pounds per square inch, which can damage wires and their insulation.
