Changes in diet have been proposed as a way to reduce carbon emissions from the food system. But there has been little research on the affordability and feasibility of low-carbon food choices in the U.S. and how these choices could affect diet and climate change.

Tropical Storm Aletta is spinning more than 440 miles off the southwestern coast of Mexico and using satellite data, NASA peered into the storm to uncover where the heaviest rain was falling.

Tropical Cyclone Ewiniar made landfall on mainland China and as the center of circulation has moved back into the South China Sea and reorganized, NASA-NOAA's Suomi NPP provided a look at the storm.

There is a link between higher serum vitamin D levels and lower plasma cholesterol levels in primary school children, new research from the University of Eastern Finland shows. Children whose serum 25-hydroxyvitamin D levels exceeded 80 nmol/l had lower plasma total and low-density lipoprotein (LDL) cholesterol levels than children whose serum 25-hydroxyvitamin D levels were below 50 nmol/l, which is often regarded as a threshold value for vitamin D sufficiency. 25-hydroxyvitamin D is the major circulating form of vitamin D. The findings were reported in one of the leading journals of endocrinology, the Journal of Clinical Endocrinology and Metabolism.

Spiral galaxies such as the Milky Way have discs which are really thin, in which the major fraction of their stars are found. These discs are limited in size, so that beyond certain radius there are very few stars left.
