An effective strategy to remotely operate snake robots

Animals have always been a great inspiration for robotic systems, as they offer fascinating natural examples of how different body structures can produce specific movements and locomotion styles. While most animal-inspired ...

'PigeonBot' brings aircraft closer to feathered-flight

Since the dawn of the aviation era, inventors have strived to build aircraft that fly as nimbly as birds, whose morphable wings allow for faster, tighter turns and more efficient gliding.

Technique identifies electricity-producing bacteria

Living in extreme conditions requires creative adaptations. For certain species of bacteria that exist in oxygen-deprived environments, this means finding a way to breathe that doesn't involve oxygen. These hardy microbes, ...

Big robot bugs reveal force-sensing secrets of insect locomotion

Researchers have combined research with real and robotic insects to better understand how they sense forces in their limbs while walking, providing new insights into the biomechanics and neural dynamics of insects and informing ...

Jellyfish-like robots could one day clean up the world's oceans

Most of the world is covered in oceans, which are unfortunately highly polluted. One of the strategies to combat the mounds of waste found in these very sensitive ecosystems—especially around coral reefs—is to employ ...

Special drone collects environmental DNA from trees

Ecologists are increasingly using traces of genetic material left behind by living organisms left behind in the environment, called environmental DNA (eDNA), to catalog and monitor biodiversity. Based on these DNA traces, ...

Species

In biology, a species is:

There are many definitions of what kind of unit a species is (or should be). A common definition is that of a group of organisms capable of interbreeding and producing fertile offspring, and separated from other such groups with which interbreeding does not (normally) happen. Other definitions may focus on similarity of DNA or morphology. Some species are further subdivided into subspecies, and here also there is no close agreement on the criteria to be used.
