A research team led by Dr. David Coltman of the University of Sheffield has discovered that hunting may permanently change the physical characteristics of the targeted species.
Dr. Coltman, of the University’s Department of Animal and Plant Sciences, is part of a team investigating effects of thirty years of trophy hunting bighorn rams at Ram Mountain in Alberta, Canada. Trophy rams are heavy, with rapidly growing horns, and are a valuable commodity.
Trophy hunting at Ram Mountain is unrestricted, being limited only by the size of the ram’s horns, and any ram reaching the minimum size can be legally shot. Eighty-five per cent of the rams shot since 1975 have been under the age of eight. This gives rams with rapidly growing horns little time to breed, as mating is generally more successful from the age of six, when rams can use their horns to fight for females.

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...
