Brain-mapping technique aids understanding of sleep, wakefulness

...Dr. Yanagisawa and his research group new hope for navigating the neural network. The technique involves genetically engineering mice to produce a "tracer" protein only in a certain population of neurons. The tracer, a nontoxic fragment of the tetanus toxin, transfers itself from one neuron in retrograde fashi...

Taking a flying jump

...ould be of interest to those building autonomously navigating robots", according to Gwyneth Card of the California Institute of Technology, who will be presenting her work on triggered escape response at the Society for Experimental Biology Annual Main Meeting in Barcelona, on Wednesday 13th July [session A7.15...

Displaced songbirds navigate in the high Arctic

...ues at Lund University in Sweden. Migratory birds navigating over long distances can determine their latitude on the basis of geomagnetic and celestial information, but longitudinal position is much more difficult to determine. In the new work, researchers investigated whether birds can define their longitude ...

Pressured by predators, lizards see rapid shift in natural selection

...to favor shorter limbs, which are better suited to navigating narrow branches and twigs. Their hypothesis was borne out. Six months after the introduction of the predator, Losos found that the Anolis population had dropped by half or more on the islands with the predators, and in comparison to the lizards on...

Two nerve cells in direct contact

...reas of science. For example, engineers developing navigating robots and driving assistance systems rely on simple and robust algorithms such as those realized by nature in insects. The mechanisms of optical flow field analysis are supremely suitable for technical implementation. As part of two projects support...

Brain maps online

...o includes a suite of free, downloadable tools for navigating and analyzing brain data. "Many users have described it as a 'Google Maps' of the brain," said Shawn Mikula, a postdoctoral researcher at UC Davis who is first author on a paper describing the work. The high-resolution maps will enable researc...

Lessons from the orangutans: Upright walking may have begun in the trees

...anging. They only tended to walk on all fours when navigating the largest branches, the researchers found. Hand-assisted bipedalism may have offered several advantages that allowed our arboreal ancestors to venture onto thin branches. They could have gripped multiple branches with their toes and distributed ...

NASA-funded robotic sub finds bottom of world's deepest sinkhole

...he DEPTHX field experiment, SLAM had been used for navigating in buildings and mines, but had never operated in an underwater environment or with such sparse sensor input. Robots typically navigate by recognizing features, but cenote walls, while irregular, lack distinctive features. To overcome this challen...
