Change in Pacific nitrogen content tied to climate change

Using deep sea corals gathered near the Hawaiian Islands, a Lawrence Livermore scientist, in collaboration with UC Santa Cruz colleagues, has determined that a long-term shift in nitrogen content in the Pacific Ocean has occurred as a result of climate change.

Thawing permafrost could lead to massive carbon release

As much as 44 billion tons of nitrogen and 850 billion tons of carbon stored in arctic permafrost could be released into the environment over the next century by the effects of global warming.

Biofuels not so green after all

The environmental benefits of biofuels are being systematically overestimated, says a University of Edinburgh scientist.

Climate change won't boost plant performance

Plants may thrive in the initial stages of global warming - but not for long. A study from Northern Arizona University shows that any improvements in growth caused by climate change disappear within ten years.

Forests soak up more CO2 than thought

North American forests might be more use than expected at slowing the pace of climate change.

Nitrogen in rocks could help counter climate change

Researchers have discovered that forest trees can tap into the nitrogen found in rocks, boosting their growth and allowing them to take up more carbon dioxide from the atmosphere.

Sun and planets built of different materials

Our sun and its inner planets may not have formed from the same materials, as previously thought, samples returned by NASA’s Genesis mission indicate.

Air Force Thunderbirds fly show on biofuel

Two of the Air Force’s Thunderbirds aerial team members recently flew their F-16s in a Department of Defense aerial team show running on a blend of camelina-based biofuel and regular jet fuel.

Ammonia from meteorites could have started life on Earth

Ammonia brought to Earth by meteorites could have helped kick-start life, says a team at Arizona State University.

Team creates precursors of life in Titan-like environment

Scientists have created organic macromolecules by zapping a Titan-like atmosphere with UV rays. The discovery supports the idea that the moon of Saturn could support life.
