A fully autonomous bat-like terrestrial robot, named Robat, can use echolocation to move through a novel environment while mapping it solely based on sound, according to a study published in PLOS Computational Biology by Itamar Eliakim of Tel Aviv University, and colleagues.
Bats use echolocation to map novel environments while simultaneously navigating through them by emitting...
Side-blotched lizards in most of the Mojave Desert have tan and brown markings that blend in well with their desert surroundings. On the Pisgah Lava Flow, however, one finds a very different population of side-blotched lizards, as black as the rocks they live on.
How do animals invade new environments different from the ones for which...
A team of scientists at the University of Wyoming has provided the first empirical evidence that ungulates (hooved mammals) must learn where and when to migrate, and that they maintain their seasonal migrations by passing cultural knowledge across generations.
The results were reported today in Science.
Biologists have long suspected that, unlike many bird, fish and insect...
Semi-autonomous and autonomous machines and robots can become moral machines using annotated decision trees containing ethical assumptions or justifications for interactions with animals.
Machine ethics is a young, dynamic discipline, which primarily targets people, not animals. However, it is important that animals are kept from harm when encountering these machines since animals cannot make informed decisions...
Asian colobine monkeys are unable to taste natural sugars, and in fact have a generally poor sense of taste. This is according to research led by Emiko Nishi of the Primate Research Institute of Kyoto University in Japan. Nishi and her colleagues found that the receptors on the tongues of colobine monkeys do not function...
Although land animals can move in many different ways, most terrestrial creatures use legs to crawl, scuttle, walk and run about. Leg propelled animals, such as mammals, insects, spiders or centipedes, feature a wealth of differently designed locomotor apparatuses and a wide range of leg numbers. In order to cover distances energy-efficiently, many terrestrial animals...
