The Future Of Money: It’s Flexible, Frictionless And (Almost) Free

Cash in the clouds—neither paper nor plastic.
Illustration: Aegir Hallmundur; Benjamin Franklin: Corbis

From Wired Magazine:

A simple typo gave Michael Ivey the idea for his company. One day in the fall of 2008, Ivey’s wife, using her pink RAZR phone, sent him a note via Twitter. But instead of typing the letter d at the beginning of the tweet — which would have sent the note as a direct message, a private note just for Ivey — she hit p. It could have been an embarrassing snafu, but instead it sparked a brainstorm. That’s how you should pay people, Ivey publicly replied. Ivey’s friends quickly jumped into the conversation, enthusiastically endorsing the idea. Ivey, a computer programmer based in Alabama, began wondering if he and his wife hadn’t hit on something: What if people could transfer money over Twitter for next to nothing, simply by typing a username and a dollar amount?

Coral Reefs Form On 'Ancient Template'

The honeycomb reef shape dominates the region.

From The BBC:

Red Sea coral reefs get their complex shape from an ancient 'seabed template', say scientists.

Their distinctive appearance can be seen clearly in satellite images of the region and has its origin in seabed erosion thousands of years ago.

The scientists say the corals have simply adopted and accentuated the pattern created in once-exposed rock moulded by heavy rains.

They presented the findings at the Ocean Sciences meeting in Portland, US.

New Space Engines May Trade Fuel For Photons

From Popular Mechanics:

Interplanetary travel may soon be powered by propulsion systems lifted from sci-fi novels, as researchers reach for faster, lighter space engines.

Chemical combustion engines are an unbeatable technology for escaping Earth’s atmosphere and gravitational pull. In space, however, these rockets are inefficient—they burn through huge quantities of fuel while generating more thrust than necessary. That’s why researchers are increasingly turning to nonchemical propulsion systems, which could drastically lighten spacecraft while achieving higher speeds. Some of the ideas being researched, like antimatter engines, depend on established physics but go far beyond current technology. “Someone’s got to think beyond the obvious,” says Marc Millis, a propulsion physicist at NASA’s Glenn Research Center. “You have enough other people in the world doing the next obvious thing. By reaching beyond that, you can discover the breakthroughs other folks aren’t even looking for, and change everything.”
