Researchers leveraging AI to train (robotic) dogs to respond to their masters      (via sciencedaily.com)     Original source 

An international collaboration seeks to innovate the future of how a mechanical man's best friend interacts with its owner, using a combination of AI and edge computing called edge intelligence. The overarching project goal is to make the dog come 'alive' by adapting wearable-based sensing devices that can detect physiological and emotional stimuli inherent to one's personality and traits, such as introversions, or transient states, including pain and comfort levels.

Taco-shaped arthropod fossils gives new insights into the history of the first mandibulates      (via sciencedaily.com)     Original source 

Palaeontologists are helping resolve the evolution and ecology of Odaraia, a taco-shaped marine animal that lived during the Cambrian period. Fossils reveal Odaraia had mandibles. Palaeontologists are finally able to place it as belonging to the mandibulates, ending its long enigmatic classification among the arthropods since it was first discovered in the Burgess Shale over 100 years ago and revealing more about early evolution and diversification.

Controlling mosquito populations through genetic breeding      (via sciencedaily.com)     Original source 

Researchers have found a new way to identify genetic targets useful for control of mosquito populations, potentially offering an alternative to insecticides. Their study focused on the genetic basis of species incompatibility. They crossed Ae. aegypti, a major global arboviral disease vector, and its sibling species, Ae. mascarensis, from the Indian Ocean. When offspring is crossed back with one parent, about 10 percent of the progeny becomes intersex and is unable to reproduce.

Ant insights lead to robot navigation breakthrough      (via sciencedaily.com)     Original source 

Have you ever wondered how insects are able to go so far beyond their home and still find their way? The answer to this question is not only relevant to biology but also to making the AI for tiny, autonomous robots. Drone-researchers felt inspired by biological findings on how ants visually recognize their environment and combine it with counting their steps in order to get safely back home. They have used these insights to create an insect-inspired autonomous navigation strategy for tiny, lightweight robots. It allows such robots to come back home after long trajectories, while requiring extremely little computation and memory (0.65 kiloByte per 100 m). In the future, tiny autonomous robots could find a wide range of uses, from monitoring stock in warehouses to finding gas leaks in industrial sites.

Cuttlefish can form false memories, too      (via sciencedaily.com)     Original source 

During an event, details like what you saw, smelled, and felt aren't stored as a single memory. Rather, they are encoded and stored in your brain separately. To retrieve that memory, those pieces must get put back together. When that doesn't happen in the right way or details are distorted, it can lead to the creation of false memories. Now researchers have evidence that the common cuttlefish may create false memories, too.
