I cannot help but see the sarcasm of this article that takes the "uto" or the "mei" together with research facilities in Hawai'i and propose it as a solution for the plight of those suffering from climate change and poverty in the Caribbean!
As stated, there are some things that really makes you go "hmmmmm..."
Ben Kestner studied flute at the London College of music and in Berlin with Andreas Blau and after spending time playing and teaching he pursued a career in education. He is currently Middle School Principal at St. John's International School in Belgium. He believes that we need to push the reset button when we talk about the future of education and start again.
Getting foreign gadgets to play nice with the local power grid is a nightmare any time you travel internationally. Here's why every country on the planet (except yours) totally screwed up indoor wiring.
The electric sail (ESAIL), invented by Dr. Pekka Janhunen at the Finnish Kumpula Space Center in 2006, produces propulsion power for a spacecraft by utilizing the solar wind. The sail features electrically charged long and thin metal tethers that interact with the solar wind. Using ultrasonic welding, the Electronics Research Laboratory at the University of Helsinki successfully produced a 1 km long ESAIL tether. Four years ago, global experts in ultrasonic welding considered it impossible to weld together such thin wires. The produced tether proves that manufacturing full size ESAIL tethers is possible. The theoretically predicted electric sail force will be measured in space during 2013.
An electric solar wind sail, a.k.a electric sail, consists of long, thin (25-50 micron) electrically conductive tethers manufactured from aluminium wires. A full-scale sail can include up to 100 tethers, each 20 km long. In addition, the craft will contain a high-voltage source and an electron gun that creates a positive charge in the tethers. The electric field of the charged tethers will extend approximately 100 meters into the surrounding solar wind plasma.
Charged particles from the solar wind crash into this field, creating an interaction that transfers momentum from the solar wind to the spacecraft. Compared with other methods, such as ion engines, the electric sail produces a large amount of propulsion considering its mass and power requirement. Since the sail consumes no propellant, it has in principle an unlimited operating time.
The electric sail is raising a lot of interest in space circles, but until now it has been unclear whether its most important parts, i.e. the long, thin metal tethers, can be produced. The team at the University of Helsinki is apparently the first one in the world to use ultrasonic welding to join wires together into a tether, says the team leader, Professor Edward Hæggström from the Department of Physics.
Partnership vital for Pacific Islands Development Forum: Dr Rodgers
As new organisations are formed there’s danger of forgetting those that have been created before so the Pacific Islands Development Forum (PIDF) needs to build partnership, says outgoing Pacific Community Director-General Dr Jimmie Rodgers.

The use of bone stem cells combined with a degradable rigid material that inserts into broken bones and encourages real bone to re-grow has been developed at the Universities of Edinburgh and Southampton.
Researchers have developed the material with a honeycomb scaffold structure that allows blood to flow through it, enabling stem cells from the patient's bone marrow to attach to the material and grow new bone. Over time, the plastic slowly degrades as the implant is replaced by newly grown bone.
Scientists developed the material by blending three types of plastics. They used a pioneering technique to blend and test hundreds of combinations of plastics, to identify a blend that was robust, lightweight, and able to support bone stem cells. Successful results have been shown in the lab and in animal testing with the focus now moving towards human clinical evaluation.
Richard Oreffo, Professor of Musculoskeletal Science at the University of Southampton, comments: "Fractures and bone loss due to trauma or disease are a significant clinical and socioeconomic problem. This collaboration between chemistry and medicine has identified unique candidate materials that support human bone stem cell growth and allow bone formation. Our collaborative strategy offers significant therapeutic implications."
Professor Mark Bradley, of the University of Edinburgh's School of Chemistry, adds: "We were able to make and look at a hundreds of candidate materials and rapidly whittle these down to one which is strong enough to replace bone and is also a suitable surface upon which to grow new bone. "We are confident that this material could soon be helping to improve the quality of life for patients with severe bone injuries, and will help maintain the health of an ageing population."

Just over a week after astronomers boldly announced that they would discover an Earth twin elsewhere in the universe within the year, NASA's Kepler telescope spotted a pretty good candidate. Unglamorously named KOI 172.02 -- KOI stands for Kepler Object of Interest -- this planet is the most Earth-like planet astronomers have discovered yet.
The differences are slight. It's roughly 50 percent larger than Earth and orbits a star that closely resembles our own sun at a distance that would make the surface of the planet habitable. (The size makes it a "super Earth" rather than an "Earth twin.") With an 242-day long year, it's slightly closer to its star than the Earth is to the Sun but otherwise enjoys all of the same ideal conditions as we do, as far as astronomers can tell. "This was very exciting because it's our fist habitable-zone super Earth around a sun-type star," said Natalia Batalha, a Kepler co-investigator at NASA's Ames Research Center in California. "It's orbiting a star that's very much like our sun. Previously the ones we saw were orbiting other types of stars."
In a way, the discovery is a bit underwhelming thanks the recent flurry of exciting exoplanet news. We learned back in October that the closest star system to our own was home to several planets, including an Earth-sized planet. Then at the start of the new year, the team analyzing data from NASA's Kepler planer-finding space telescope announced the discovery of 461 new unconfirmed planets as well as the fact that that the Milky Way galaxy alone was home to more than 17 billion Earth-sized planets. They said they'd find an Earth twin among them by the end of the year. Compared to the days when we didn't know there were any other planets in the universe at all, and suddenly the chances that alien life exists start to look pretty strong. At least that's what the experts say. "It's a big deal -- It's definitely a good candidate for life," said astrophysicist Mario Livio about KOI 172.02. "Maybe there's no land life, but perhaps very clever dolphins."
