New process for making ice that burns
Gas hydrates have generated worldwide excitement about their potential as a new energy resource and as a potential deep freeze to store greenhouse gases like methane and carbon dioxide. Methane hydrates literally ice that burns are deep deposits of frozen methane that burst into flame when brought to the surface.
Found in abundance under the seafloor in U.S. coastal waters, among other places, gas or clathrate hydrates may hold enough natural gas to supply the world for centuries. One barrier to exploiting this treasure has been difficulty in making gas hydrates in the laboratory for research.
Yong Ba and associates at California State University in Los Angeles report an advance toward overcoming that barrier, scheduled for May 17 publication in the ACS journal, Energy & Fuels. The researchers wanted to make hydrates in sealed glass tubes that can be analyzed with a mainstay laboratory tool called nuclear magnetic resonance (NMR).
With conventional technology, it took up to a year to make a gas hydrate in a sealed NMR tube. Bas new technique shortens the time to about one week. They are using the new method to make gas hydrates in order to understand the factors that control the stability of hydrates a key consideration in engineering gas hydrates as an energy resource.

Peaceful recipe for a fine kettle of fish
Aquaculture already supplies about one-third of the fish and shellfish sold today. Reliance on fish farming to meet public demand for this healthful source of protein will increase as the world's conventional fish catch from oceans and other sources continues to decline.
With the expansion of aquaculture has come a new awareness about the welfare of farmed fish in their final days. Martine Morzel and associates are reporting that pre-s
