Lizards gone wild
Despite social notions of race, human populations around the world are genetically so similar that geneticists find no different sub-species among them. The genetic continuity of human populations is the exception rather than the rule for most animal species, however.
Richard Glor, graduate evolutionary biology student in Arts & Sciences at Washington University in St. Louis, has found extensive genetic differentiation among populations of numerous Anolis lizard species inhabiting single Caribbean islands. While to the naked eye the lizards appear to be uniform, these lizards from the islands of Cuba, Puerto Rico, Hispaniola and Jamaica all show a surprising amount of genetic diversity. Glor goes to the islands and collects lizard samples to study morphology, or body features, and color patterns and then sequences DNA from the different species.

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure

Scientists developed specially coated nanometer-sized vehicles that can be actively moved through dense tissue like the vitreous of the eye. So far, the transport of nano-vehicles has only been demonstrated in model systems or biological fluids, but not in real tissue. The work was published in the journal Science Advances and constitutes one step further towards nanorobots becoming minimally-invasive tools for precisely delivering medicine to where it is needed.
Researchers of the “Micro, Nano and Molecular Systems” Lab at the Max Planck Institute for Intelligent Systems in Stuttgart, together with an international...
