Researchers have succeeded in developing a new microscope capable of observing the magnetic sensitivity of photochemical reactions believed to be responsible for the ability of some animals to navigate in the Earth's magnetic field, on a scale small enough to follow these reactions taking place inside sub-cellular structures.
Crystalline materials have atoms that are neatly lined up in a repeating pattern. When they break, that failure tends to start at a defect, or a place where the pattern is disrupted. But how do defect-free materials break? Until recently, the question was purely theoretical; making a defect-free material was impossible. Now that nanotechnological advances have made such materials a reality, however, researchers have shown how these defects first form on the road to failure.
The Dutch National Institute for Public Health and the Environment has commissioned the development of a strategy to evaluate the potential for read-across in cases of missing data for nanomaterials, with a focus on fulfilling data requirements in regulatory frameworks.
Northwestern University's International Institute for Nanotechnology has announced the establishment of the $250,000 Kabiller Prize in Nanoscience and Nanomedicine and the $10,000 Kabiller Young Investigator Award in Nanoscience and Nanomedicine.
Natural channel proteins are integrated into artificial membranes to facilitate the transport of ions and molecules. Researchers have now been able to measure the movement of these channel proteins for the first time.
