Your Brain Stays Half Awake When You Sleep In A New Place

Your Brain Stays Half Awake When You Sleep In A New Place

If you’ve ever slept in a hotel, gone camping, or even slept over at a friend’s pad, chances are you’ve woken up the next day feeling groggy and bleary-eyed. Even if you don’t remember tossing and turning, you probably felt pretty tired the next day. Well, that’s because nature dies hard. When we sleep in a new place, our brains are actually in survival mode, only turning half off, with one hemisphere remaining more “awake” than the other.

Raccoons Pass Famous Intelligence Test—By Upending It

Raccoons Pass Famous Intelligence Test—By Upending It

Raccoons are notoriously pesky, but are they as clever as a crow? Scientists recently put the masked mammals through the Aesop's Fable test, which measures if animals can discern cause and effect by displacing water to access food. The experiment is based on the story in which a thirsty crow can’t drink from a pitcher with a low level of water. By dropping in stones, the bird raises the water level and is able to drink.

How the Double Slit experiment could determine sentient AI

How the Double Slit experiment could determine sentient AI

A week ago I saw a speech by an American professor, where he explained his research findings, which was related to meditation and the double slit experiment. For those not acquainted with the double slit experiment, it basically implies that only as a particle is observed, it gains a position in time and space. Before observation, it is merely a potentiality wave. The professor had over several years been conducting experiments where he had people meditate, and visualise themselves observing an electron, as it passed through a double slit.

A New Theory Explains How Consciousness Evolved

A New Theory Explains How Consciousness Evolved

Ever since Charles Darwin published On the Origin of Species in 1859, evolution has been the grand unifying theory of biology. Yet one of our most important biological traits, consciousness, is rarely studied in the context of evolution. Theories of consciousness come from religion, from philosophy, from cognitive science, but not so much from evolutionary biology. Maybe that’s why so few theories have been able to tackle basic questions such as: What is the adaptive value of consciousness? When did it evolve and what animals have it?
