For the first time, scientists have a promising "candidate" vaccine for HIV.
- The vaccine only gives around a 30% chance of developing immunity. That has to rise to 50% or more. At that level, the transmission rate should drop enough that AIDS should pretty much be wiped out as a widespread disease. Sucks for the 50% of the population if they get exposed though.
- The current trial involved six injections over a six month period, that's going to be really difficult to manage in lots of developing countries especially in Africa.
- The vaccine is a combination of two other vaccines and the researchers aren't sure whether its one of the two or the combination that's working.

The coin can land on edge, be snatched by some guy walking by, be eaten by a bird, or just disappear when all its particles at a quantum level randomly jump in different directions. Those thing are all possible even if you would need a whole lot of 0's to figure the odds on the last one.
Here's one of those stories that makes you go "whoa".
The world's most powerful particle accelerator, the Large Hadron Collider (LHC), could be used to test the principles behind hyperdrive, a possible future form of spacecraft propulsion that could drive spacecraft at a good fraction of the speed of light.

Probably decades or centuries away from reality if its even possible.
In 2008, Masahiro Hotta of Tohoku University in Sendai, Japan, wrote a paper called:
Quantum Energy Teleportation in Spin Chain Systems
In the abstract, he says:
We propose a protocol for quantum energy teleportation which transports energy in spin chains to distant sites only by local operations and classical communication. By utilizing ground-state entanglement and notion of negative energy density region, energy is teleported without breaking any physical laws including causality and local energy conservation. Because not excited physical entity but classical information is transported in the protocol, the dissipation rate of energy in transport is expected to be strongly suppressed.
This article was published in the Journal of the Physical Society of Japan last year. Slowly, the discussion has spread through academic until lay publications are now referring to it. In his paper, Hotta basically proves the theoretical soundness of the teleportation of energy (across an infinite stretch of space), with practically no loss of energy in the transmission. The theory involves Quantum entanglement, and conservation of energy.
Here's the Pop Sci Article about it.
And here's the Discovery News article.
Of course, there's been no approach towards practical applications yet. But imagine the possibilities! We could transport energy from anywhere in the world. It wouldn't matter that one part of the world gets disproportionate sun or tides - we could just move that energy anywhere we wanted. Even better, we could one day have unmanned orbital power stations near the sun sending practically unlimited amounts of energy to the earth.

Doesn't massive amounts of energy from the sun transport itself here on its own every day? The problems are in collection and storage, not in transport.
