How bees in a hive interact somewhat similarly to neurons in a brain, enabling decisions to be taken.
Same setup, but with the neutrinos sent in very short, widely spaced pulses to make the timing more accurate.
Is the wavefunction a mathematical convenience predicting probabilities for different observations of a particle, or does it have physical reality? A new mathematical theorem suggests the wavefunction is a real physical object.
The blackest known exoplanet. It’s the size of Jupiter, too hot to have clouds in the atmosphere, and would be even blacker if it weren’t just about red hot.
Experiments using a split treadmill. Among other things, it turned out that people can quickly learn to simultaneously walk forwards and backwards at different speeds with different legs, and that it takes about the same length of time to readjust to normal walking afterwards.
“According to research that hasn’t yet been performed … ” “In a controversial move, popular sicence journal The Daily Mail … ” “The scientist, who doesn’t actually use Twitter, said … ” Wonderful spoof article by Martin Robbins.
Fluid flow follows similar equations to those used in relativity, meaning parallels to phenomena such as black holes can be created in the lab and studied. In this instance, they created a parallel situation to one where time turns into space.
Listening to their own language, people with dyslexia did worse at recognising different voices. Listening to an unfamiliar language, there was no difference between people with and without dyslexia. The researchers theorise that this is to do with how the brain processes phonemes (the basic units of sound in a language).
The history of evolution in animated graffiti and more. Amazing stop-motion video by wall artist Blu.
A hyphothesis that the universe started off with only one space dimension then acquired more as it expanded. An observational test is suggested. Unfortunately, the test involves not detecting gravitational waves …
