The mode of packaging of the genomic DNA in the cell nucleus determines patterns of gene expression. Researchers have used DNA-based nano-tweezers to measure the forces between nucleosomes, the basic packing units of nuclear DNA.
Scientists have succeeded in creating fiber-reinforced soft composites, or tough hydrogels combined with woven fiber fabric. These fabrics are highly flexible, tougher than metals, and have a wide range of potential applications.
Scientists examine the deliberate switching of individual photochromic molecules. Their findings are opening up new research possibilities for visualizing the structures of complex molecules and even entire biological systems.
