Cells are very good at protecting their precious contents—and as a result, it's very difficult to penetrate their membrane walls to deliver drugs, nutrients or biosensors without damaging or destroying the cell. One effective ...

(Phys.org)—A combined team of researchers from the U.S. and Germany has discovered a very thin layer of fat covering the scales of a single species of snake. In their paper published in Journal of the Royal Society Interface, ...
Some snake species slither across the ground, while others climb trees, dive through sand or glide across water. Today, scientists report that the surface chemistry of snake scales varies among species that negotiate these ...
