Confirmed: oil from Deepwater Horizon disaster entered food chain
For months, crude oil gushed into the water at a rate of approximately 53,000 barrels per day; new study confirms that not only did oil affect the ecosystem in the Gulf during the blowout, but it was still entering the food web after the well was capped

New method for cleaning up nuclear waste
There are more than 436 nuclear power plants operating in thirty countries, and they create a lot of nuclear waste; one of the more toxic elements in that waste is radionuclide technetium (99Tc); approximately 305 metric tons of 99Tc were generated from nuclear reactors and weapons testing from 1943 through 2010

Simulation of nuclear fusion shows high-gain energy output
High-gain nuclear fusion could be achieved in a preheated cylindrical container immersed in strong magnetic fields, according to a series of computer simulations performed at Sandia National Laboratories; the method appears to be fifty times more efficient than using X-rays — a previous favorite at Sandia — to drive implosions of targeted materials to create fusion conditions

Asteroid to miss Earth next year, but not by much
When it whizzes past Earth in 2013, a newly discovered asteroid is going to miss our planet — but not by much; the 50-meter space rock is expected to come closer than many satellites, highlighting the growing need to keep watch on hazards from above

Good news: metal-reducing bacteria interacts with plutonium oxide
Studies show that under oxygen-free conditions, plutonium(IV) hydrous oxide, the most common subsurface form of plutonium, does not become very soluble; this information will help in developing effective approaches for isolating and removing the contaminants before they can impact humans and the environment

Bi-plane to revive supersonic travel
Researchers say that the best way to revive supersonic air travel – which came to an end with the retirement of the Concorde in 2003 – would be by building a plane with two wings to a side; computer models show that a bi-plan produces significantly less drag than a conventional single-wing aircraft at supersonic cruise speeds

Iron is key to reversing climate change
Scientists and politicians are trying to devise ways to reduce CO2 emissions — but when it comes to getting rid of the CO2 that is already there, nature itself plays an important role: carbon dioxide is removed from the atmosphere and safely trapped on the ocean floor through a natural reaction that fixes the molecule to organic carbon on the surface of large bodies of water
