Everything interacting…
Keeping qubits stable – those quantum equivalents of classic computing bits – will be key to realizing the potential of quantum computing. Now scientists have found a new obstacle to this stability: natural radiation. It's around us all the time, and so this poses something of a problem for future quantum computers. Through a series…

Brain. Information.
The brain never processes the same information in the same way. Scientists have found out why this is the case and how it works. A decisive role plays a critical state of the neuronal networks. It seems that there is always a certain amount of activity between the neurons of a network, even if there…

Limits of measurements… Limits of out self…
The limits of classical measurements of mechanical motion have been pushed beyond expectations in recent years. But the sensitivity that we can achieve using purely conventional means is limited. For example, Heisenberg's uncertainty principle in quantum mechanics implies the presence of "measurement backaction": the exact knowledge of the location of a particle invariably destroys any…

Light. Low light. Essence.
It was a puzzle about birds. Migratory birds are known to rely on Earth's magnetic field to help them navigate the globe. And it was suspected that a protein called cryptochrome, which is sensitive to blue light, was making it possible for birds to do this. Yet many of these animals are also known to…

Octopuses’ arms. Universe’s brain.
How octopuses’ arms make decisions: Researchers studying the behavior and neuroscience of octopuses have long suspected that the animals' arms may have minds of their own. A new model is the first attempt at a comprehensive representation of information flow between the octopus's suckers, arms and brain, based on previous research in octopus neuroscience and…
