This Week: Ancient water = ancient habitat?
In the News: Texas is dry and hot. Global warming?
The first ocean wave energy-capturing device with a permit to connect back to a public power grid will enter the Pacific next month. How much power could the U.S. potentially harness from the waves crashing into its the coastline? According to researchers, wave energy might be one of our best renewable resources.
By tweaking the conventional recipe, researchers have sped up electricity movement in a lithium battery by 100X. Want to charge your electric car in minutes or your phone in seconds?
Oils in spent coffee grounds are easily converted into biodiesel — a renewable source of transportation energy. Bottoms up for CofFuel?
Did the arrival of 4,000,000,000,000,000,000 tons of space junk start the formation of organic molecules roughly 4 billion years ago? “Could be,” says a new study from Japan…
Frosty questions: Are some snowflakes identical? How do flakes form, and how does weather affect their shape? How does ice in the atmosphere affect weather and climate? And where does the jet stream fit in this picture?
Plug-in hybrids mean more than just extra spending cash for drivers, though. They could offer a new path through the maze of the electric grid, and help to boost the use of alternative energy.
Could carbon storage help control warming? The oil industry already injects CO2 into deep rocks. Is it possible to capture CO2 from coal plants, and pump it deep underground?
Global warming gets worse. Petroleum grows scarce. Should we start making biofuels bigtime? If so, should we get the ethanol from corn, or from plant wastes?

How do volcanoes work (p. 2)? How do we predict them (p. 3)? How do they change the landscape (p. 4)? How does life return after the eruption (p. 6)?
Astronomers have just seen galaxies from the first billion years of the universe. They are also racing to understand dark energy, the force that’s spreading the universe apart.
The Spallation Neutron Source, a mammoth science project involving the collaboration of six national laboratories, is scheduled to be completed 2006.
Edward Teller helped invent the hydrogen bomb, then pushed missile defense. By public advocacy and secret research, he changed the 20th century.
Tornadoes kill 60 Americans each year. How do we predict tornadoes? How do we make houses safer? Where do tornadoes get their energy?
