Predator avoidance of noxious prey, aposematism and defensive mimicry are normally associated with bright, contrasting patterns and colours. However, noxious prey may be unable to evolve conspicuous coloration because of other selective constraints, such as the need to be inconspicuous to their own prey or to specialist predators. Many venomous snakes, particularly most vipers, display patterns...

The light color of mice that inhabit the sandy dunes of Florida's coast have served as a textbook example of adaptation for nearly a century, despite the fact that the selective advantage of crypsis has never been directly tested or quantified in nature. Using plasticine mouse models of light and dark color, we demonstrate a strong selective advantage for mice that match their local background ...

OBJECTIVE Facial reconstruction of mummies and corpses in general is important in anthropological, medical, and forensic studies. The purpose of our study was to evaluate the role of MDCT examination for 3D facial reconstruction and report the results of multidisciplinary work performed by radiologists, anthropologists, and forensic police in reconstructing the possible physiognomy of an ancien...

Polyacrylamide gel electrophoresis (PAGE) is a standard procedure for identifying and analyzing polypeptides (1). Samples are prepared from cell lysates, subjected to electrophoresis and stained with silver nitrate or Coomassie Brilliant Blue (CBB) allowing direct visualization of bands within gels (1,5). Samples can also be radiolabeled, for example with [35S]methionine, and after electrophor...

The coevolutionary relationships between brood parasites and their hosts are often studied by examining the egg rejection behaviour of host species using artificial eggs. However, the traditional methods for producing artificial eggs out of plasticine, plastic, wood, or plaster-of-Paris are laborious, imprecise, and prone to human error. As an alternative, 3D printing may reduce human error, en...

Combat helmets are the primary system for protecting head against ballistic impacts. Generally, combat have been evaluated using a plasticine surrogate based on international standards. More realistic human models recently introduced to assess helmet performance considering biomechanical requirements. In this work, Hybrid III dummy and neck has evaluate of impact live ammunition at different lo...
