I can see people hacking this and then doing all sorts of strange things with it. What if you could disable the rendering of the Minecraft game and then simulate days or weeks of progress in mere hours? Or have villagers that dynamically respond to your actions.

You could have different personalities for the bots, miners and farmers and plain old assistants that protect you and help you find cool stuff.

White storks have stopped migrating from Europe to Africa for the winter, say researchers. Instead, they remain in Spain and Portugal year-round, feasting on landfills' 'junk food.'

The Secrets of the Wave Pilots | NYT Magazine

Fascinating stuff - the art and science of using subtle sub-signals among the wave-cacophony of the seas as reliable navigational "landmarks", which are immune to the vagaries of the tide and storms. Regarding the deep connection between navigation and storytelling -- the just-begun USA network series Underground has fugitive slaves exchanging a map of the route north to the Ohio River in the form of an innocuous-sounding children's story.

One wonders how much such ancient "I can't believe they were able to do ____ using just _____" ingenuity has been lost forever. As a wise man once said, "you can learn a lot just by paying attention" -- the kind of attentiveness and surroundings-awareness to which modern nav-tech is inimical.

New lithium battery ditches solvents, reaches supercapacitor rates
The all solid-state battery operates between -30 and 100 degrees Celsius.

Quote:

For most of us, the only way we judge a battery is by how long it can deliver electrons to our favorite devices. But many applications require more than that. They need batteries that operate across a large temperature range, are compact or flexible, and can manage a fast charge/discharge rate. Plus, we'd all like them not to explode or fail suddenly.

Most energy storage tech involves balancing a trade-off among these various properties. But a new report from a collaboration between academic researchers and Toyota seems to promise it all: a battery more compact than lithium-ion, a better energy density, the charge speed of a supercapacitor, and improved safety. How is this all possible? They got rid of the liquid electrolyte typical of most lithium-ion batteries.

That's quite the idea they have. I would imagine there are applications that go far beyond a magnetic spring-n-latch.
