The Remarkable Self-Organization of Ants

They have only a few simple rules for building complex structures
‘…The researchers discovered three main rules: The ants picked up grains at a constant rate, approximately 2 grains per minute; they preferred to drop them near other grains, forming a pillar; and they tended to choose grains previously handled by other ants, probably because of marking by a chemical pheromone.

‘The researchers used these three rules to build a computer model that mimicked the nest-building behavior. In the model, virtual ants moved randomly around a three dimensional space, picking up pieces of virtual sand soaked in a virtual pheromone. The model ants created pillars that looked just like those made by their biological counterparts. The researchers could alter the pillars’ layout by changing how quickly the pheromone evaporates, which could explain why different environmental conditions, such as heat and humidity, influence the structure of ant nests. (They published a preliminary version of the model in a conference report in 2011 but haven’t yet published the more refined version, which better mimics real ants.)…’

The Johammer Electric Motorcycle
Can you beat an oil crisis better than with an electric bike that goes 200 km
‘Apart from the bike’s utterly bizarre retro-futuristic styling, a few other things are immediately striking. It doesn’t have a traditional dash, opting instead to integrate the speedo and charge indicator into a panel on the mirrors (I shudder to think what they’d cost to replace when it falls over!).

‘But the big ticket item is the fantastic battery range. Fitted with a beefy 12.7 kWh battery stack, the Johammer joins the Zero S ZF11.4 among the first electric bikes to boast a 200 km (124 mi) range when fully charged. That’s a significant psychological number for bikers, because 200 km is a decent fuel range for a petrol-powered bike…’
