If Americans adopted the recommendations the USDA's "Dietary Guidelines for Americans, 2010," diet-related greenhouse gas emissions would increase 12 percent, according to scholars, and if Americans reduced their daily caloric intake to the recommended level of about 2,000 calories while shifting to a healthier diet, greenhouse gas emissions would decrease by only 1 percent.

What must happen is that Americans must switch to no animal products, say Martin Heller and Gregory Keoleian of the University of Michigan's Center for Sustainable Systems, who looked at the greenhouse gas emissions associated with the production of about 100 foods, as well as the potential effects of shifting Americans to a diet recommended by the U.S. Department of Agriculture.

Researchers say that magma columns in the Earth's interior can cause continental breakup – under the right circumstances.

In some parts of the Earth, material rises upwards like a column from the boundary layer of the Earth's core and the lower mantle to just below the Earth's crust hundreds of kilometers above. Halted by the resistance of the hard crust and lithospheric mantle, the flow of material becomes wider, taking on a mushroom-like shape. Specialists call these magma columns mantle plumes or simply plumes.

Supplements are more likely than medications to lead to death or liver transplantation, according to a new paper in Hepatology.

The new research shows that liver injury caused by herbals and dietary supplements increased from 7% to 20% in the study group over a ten-year period. Liver injury caused by non-bodybuilding supplements is most severe, occurring more often in middle-aged women and more frequently resulting in death or the need for transplantation than liver injury from bodybuilding supplements or conventional medications.
