The test was organised by Euratom - the European Atomic Energy Community - together with Finnish radioactive waste management company Posiva Oy.‍The ANYmal robot has been under development for many years. The roots of the ANYbotics company go back to the Swiss Institute of Technology, EHT. A group of researchers from the educational institution built the first four-legged robot back in 2009, and ANYbotics was founded for the commercialisation of this technology in 2016.The ANYmal robot uses laser sensors and cameras to observe the environment and can locate its own position very precisely. By combining observation data with location data - such as a map or area scan data - it can plan its navigation route independently when necessary.Posiva said Onkalo offered a unique framework for the robot to move, noting that there are tunnels in other parts...

How consciousness may rely on brain cells acting collectively – new psychedelics research on rats

Psychedelics can help uncover consciousness. agsandrew/Shutterstock Pär Halje, Lund UniversityPsychedelics are known for inducing altered states of consciousness in humans by fundamentally changing our normal pattern of sensory perception, thought and emotion. Research into the therapeutic potential of psychedelics has increased significantly in the last decade. While this research is important, I have always been more intrigued by the idea that psychedelics can be used as a tool to study the neural basis of human consciousness in laboratory animals. We ultimately share the same basic neural hardware with other mammals, and possibly some basic aspects of consciousness, too. So by examining what happens in the brain when there’s a psychedelically induced change in conscious experience, we can perhaps glean insights into what consciousness is in the first place.We still don’t know a lot about how the networks of cells in the brain enable conscious experience. The dominating view is that consciousness somehow emerges as a collective phenomenon when the dispersed information processing of individual neurons (brain cells) is integrated as the cells interact.But the mechanism by which this is supposed to happen remains unclear. Now our study on rats, published in Communications Biology, suggests that psychedelics radically change the...
