Cuttlefish have ability to exert self-control, study finds

Humans, chimps, parrots and crows have evolved to exert self-control, a trait linked to higher intelligence. Now, researchers say cuttlefish – chunky squid-like creatures with eight arms – also have the ability to delay gratification for a better reward.

Researchers used an adapted version of the Stanford marshmallow test, in which children were given the choice of scoffing an immediate reward (one marshmallow) or waiting to earn a delayed, but better, reward (two marshmallows), on six cuttlefish in an aquarium environment.
The invertebrates were presented with chambers that were marked with different visual cues in the form of shapes. For instance, one cue meant the moment food was put in that chamber, the door would open – while another meant that when food was placed in that chamber, there would be a delay before the door opened. One of the cues was counterintuitive – even though the food was placed in the chamber, and the door was opened, there was an extra layer of plastic thwarting the cuttlefish from eating the reward.

When the cuttlefish were exposed to the chambers initially, they immediately attacked when they saw the food. Over time, they realised that each chamber had its own rules. Eventually, the molluscs didn’t even bother approaching the “unobtainable” chamber because they learned they could never secure access to the food...
This information will be very useful when the cuttlefish next attack out aquatic outposts.

Space plasma hurricanes discovered above North Pole - where it rains electrons.
Scientists say they have confirmed the existence of space hurricanes, with a 600 mile-wide mass spotted above the North Pole.

Researchers led by China's Shandong University used satellite data to identify the space hurricane, finding it was not a whirling pattern of air but of plasma - ionised gas.

The mass was raining electrons instead of water and it lasted nearly eight hours before it broke down.

Professor Mike Lockwood, space scientist at the University of Reading, said the hurricanes could be a universal phenomena at planets and moons with magnetic fields and plasma.

He said: "Until now, it was uncertain that space plasma hurricanes even existed, so to prove this with such a striking observation is incredible. Tropical storms are associated with huge amounts of energy, and these space hurricanes must be created by unusually large and rapid transfer of solar wind energy and charged particles into the Earth's upper atmosphere.

"Plasma and magnetic fields in the atmosphere of planets exist throughout the universe, so the findings suggest space hurricanes should be a widespread phenomena."...

phenomenon
So you talk about mobs and the working classes as if they were the question. You've got that eternal idiotic idea that if anarchy came it would come from the poor. Why should it? The poor have been rebels, but they have never been anarchists; they have more interest than anyone else in there being some decent government. The poor man really has a stake in the country. The rich man hasn't; he can go away to New Guinea in a yacht. The poor have sometimes objected to being governed badly; the rich have always objected to being governed at all. Aristocrats were always anarchists. - G.K. Chesterton
