AI recreates activity patterns that brain cells use in navigation

Deep-learning algorithm spontaneously mimicked the activity of specialized neurons that tell us where we are in space. |SOURCE| Scientists have used artificial intelligence (AI) to recreate the complex neural codes that the brain uses to navigate through space. The feat demonstrates how powerful AI algorithms can assist conventional neuroscience [...] Read more

Synopsis: Revised Prediction for Mercury’s Orbit

Mercury’s orbital ellipse is predicted to shift an additional 1∘ every two billion years as a result of previously unaccounted for effects of general relativity. |SOURCE| Mercury’s orbit of the Sun isn’t fixed in space. Every 625 years, the ellipse shifts by 1∘ because of its gravitational interactions with the planets and the Sun. Now Clifford [...] Read more

People Lived in This Cave for 78,000 Years

Excavations in Panga ya Saidi suggest technological and cultural change came slowly over time and show early humans weren’t reliant on coastal resources |SOURCE| There’s evidence human beings have occupied the city of Damascus in Syria for 11,000 years. But that’s nothing compared to the Panga ya Saidi cave network in Kenya’s Rift Valley. Ruth [...] Read more

New state of matter made from atoms inside other atoms discovered by physicists

Scientists show 'Rydberg polarons' can be created by increasing orbit of electrons at temperatures approaching absolute zero. |SOURCE| A new state of matter made up of “giant atoms” filled with other, normal atoms, have been revealed in experiments. Called Rydberg polarons, they can be created if an electron can be encouraged to orbit the nucleus [...] Read more
