Researchers show that bond orders of individual carbon-carbon bonds in polycyclic aromatic hydrocarbons and fullerenes can be distinguished by noncontact atomic force microscopy (AFM).
Movement of animal groups varies between species, but has always been assumed to reduce predation risk. Here, virtual prey that swim in a coordinated, collective manner are less likely to be attacked by a predatory fish.
Administration of antibiotics is shown to alter the gut microbiome in mice. Significant changes in taxonomy and metabolic gene expression were observed.
