Pac-Man-like molecule chews up uranium contamination
Uranium leaches into groundwater from natural deposits of its ore, depleted uranium munitions, nuclear facilities, and the detritus of uranium mining; removing uranium from groundwater is very difficult: Not only does uranium bind very strongly to oxygen — it is also soluble, making dissolved uranium virtually impossible to remove; British scientists find an innovative solution

As nuclear power spreads, so do worries about safety
Of the more than 100 nuclear reactors now being built, planned, or on order, about half are in China, India, and other developing nations; China has 11 nuclear plants and plans to bring more than 30 others on line by 2020; MIT report says China may need to add as many as 200 reactors by 2050; imagine China bringing to nuclear matters the same rigor and corruption-free approach it brings to inspection of food, children toys, and medicines

Enhanced Geothermal Systems: A Promising Source of Round-the-Clock Energy
With its capacity to provide 24/7 power, many are warming up to the prospect of geothermal energy. Scientists are currently working to advance human-made reservoirs in Earth’s deep subsurface to stimulate the activity that exists within natural geothermal systems.
Experts Discuss Geothermal Potential
Geothermal energy harnesses the heat from within Earth—the term comes from the Greek words geo (earth) and therme (heat). It is an energy source that has the potential to power all our energy needs for billions of years.
