Researchers examine carbon capture and storage to combat global warming

..., he said. Capturing carbon dioxide from small, mobile sources, such as cars, would be more difficult, Orr said. But with power plants comprising 40 percent of the world's fossil fuel-derived carbon emissions, he added, the potential for reductions is significant. Not only can a lot of carbon dioxide ...

Fish extinctions alter critical nutrients in water, study shows

...osystems, especially those involving large, highly mobile fish, are almost impossible to carry out in the wild, but new methods are helping researchers better understand these systems. "Computer simulations provide a means to assess patterns of species loss in a system in which we just cannot do complex e...

Genetic pathways to curable and incurable forms of pancreatic cancer identified

...nduce cancer cells to change shape and become more mobile and invasive. It turns out that the cystic pancreatic cancer cells are resistant to these effects of TGFb and these types of cancers are also less likely to invade surrounding tissues and to metastasize, or spread, to other organs. These properties l...

Cancer researchers add spice to research against rare neuromuscular disease

...perienced a remarkable improvement. They were more mobile than their untreated counterparts, walking more normally and dragging their legs less often. Their muscles appeared to work normally, and they lived 40 percent longer than the untreated mice. In addition, the mice treated with ASC-J9 were able to mat...

Genetic surprise confirms neglected 70-year-old evolutionary hypothesis

...omosomes to relocate themselves in a genome. Those mobile sections can cause sterility in inter-species hybrids, which can act as a speciation pressure. In theory, the idea was sound, but scientists long debated whether it actually happened in nature. Eventually a competing theory involving the gradual acc...

Some butterflies travel farther, reproduce faster

... and reproduce more quickly compared to their less mobile female relatives. The study is a window to how genetic differences influence behavior and how the environment influences genetic change by favoring individuals with certain traits, said lead author Howard W. Fescemyer. The new study found significan...

Radiologists attempt to solve mystery of Tut's demise

...3,300-year-old mummy of King Tut in Egypt. Using a mobile multi-detector CT scanner, the researchers performed a full-body scan on the king's remains, obtaining approximately 1,900 digital cross-sectional images. "We found the mummy was in a critical stage of preservation," said Dr. Selim. "The body was ...

New evidence of early horse domestication

...ared to undisturbed soils. But because nitrogen is mobile in soils, it can be lost to groundwater or transferred to the atmosphere by organic and inorganic processes. Phosphorus, on the other hand, can be locked into place by calcium and iron and is more likely to be preserved in the soils for millennia. ...
