I hope you’ll excuse the exaggerated exuberance in the headline, but when I saw the image above, and then the animation lower down in this story, my first reaction really was to exclaim out loud “whoa!�
I was really struck by the two very curious whirlpool-like features on opposite sides of Earth — one giga ...read more

A neuroscientist and a marine biologist got together and decided to give octopuses MDMA. It sounds like a joke, but it really happened, and the results reveal something unique about our neurocircuitry and human evolution.
Eric Edsinger is an octopus researcher at the University of Chicago who recently helped sequence the genome of Octopus bimaculoides—the California two-spot octopus. Like most octopuses, this ...read more

Seeing a smile can make a person unconsciously smile in return, and now scientists find that digitally mimicking the voice of a smiling person can also make people reflexively smile.
Charles Darwin and his contemporaries were among the first scientists to investigate smiles. Darwin suggested that smiles and several other facial expressions are universal to all humans, rather than unique products of a person’s culture.

When it comes to studying cocaine addiction, one group of researchers has stomach acid on their brains.
In a paper published Thursday in PLOS Biology, researchers find that a surgery that diverts some bile acid into the bloodstream seems to cut back cravings among mice with a cocaine habit.
It’s a nifty angle on a pernicious problem, but it’s also another piece of evidence that bile acid, a compound produced by our ...read more
Signals in the brain hop from neuron to neuron at a speed of roughly 390 feet per second. Light, on the other hand, travels 186,282 miles in a second. Imagine the possibilities if we were that quick-witted.
Well, computers are getting there.
Researchers from UCLA on Thursday revealed a 3D-printed, optical neural network that allows computers to solve complex mathematical computations at the speed of light.
In other words, we don’t stand a chance.
Hyperbole aside, research ...read more
