A lot has been written about the perceived benefits and non-benefits of higher-than-the-human-eye-can-perceive resolutions, things like displays that go beyond HD and retina or cameras and scanners that capture imagery in pixel counts that go so far beyond the threshold of what we can see as to be meaningless, at least visually speaking.
Once punctured by wayward metal atoms, the wonder material graphene can stitch itself back together, healing over with a new patch of two-dimensional carbon atoms. This new finding sheds more light on the strange properties of graphene, and it could even lead to new graphene creation strategies.
Add another item to the list of things one can accomplish using graphene, the wonder material of the future: Clean drinking water. Graphene could cheaply and easily remove salt from seawater, potentially turning the oceans into a vast drinking supply for thirsty populations. With properly sized holes, graphene sheets may be able to serve as all-purpose filters.
Future genetic therapy could be as simple as applying a topical lotion, with nanoscale compounds soaking through your epidermis to tweak your DNA. This new class of nucleic acid structures could guard against some types of skin cancer, according to researchers at Northwestern University.
Fireflies light up summer lawns at dusk through chemical reactions, which take place between a light-emitting substance and its related enzyme. Luciferin and luciferase, respectively, could provide a natural, electricity-free glow for ambient lighting and other uses. But previous experiments to this end have not yielded very bright light.
Dentists may soon be getting a potent new weapons with which to wage the global fight against cavities. The University of Maryland has developed a novel new nanocomposite material that can be used not only as filling for cavities, but that will also kill any remaining bacteria in the tooth and regenerate the actual structure lost to decay.
