Airborne Nitrogen Shifts Nutrient Limitation in Pristine Lakes

The impact of airborne nitrogen released from the burning of fossil fuels and wide-spread use of fertilizers in agriculture is much greater that previously recognized and even extends to remote alpine lakes, according to a study published Nov. 6 in the journal Science.

Small Increases in Phosphorus Mean Higher Risk of Heart Disease

Higher levels of phosphorus in the blood are linked to increased calcification of the coronary arteries— a key marker of heart disease risk, according to a study in an upcoming issue of Clinical Journal of the American Society of Nephrology (CJASN). "This may help to explain why even early-stage chronic kidney disease (CKD) is associated with increased cardiovascular risk that is not otherwise explained by traditional risk factors," comments Katherine R. Tuttle, MD (Providence Medical Research Center, Spokane, WA).

Horse Genome Sequence and Analysis Published in Science

An international team of researchers has decoded the genome of the domestic horse Equus caballus, revealing a genome structure with remarkable similarities to humans and more than one million genetic differences across a variety of horse breeds. In addition to shedding light on a key part of the mammalian branch of the evolutionary tree, the work also provides a critical starting point for mapping disease genes in horses.
