...more likely to be deficient than those who were fed with baby formula, which is fortified with a large dose of vitamin D, according to the study. A large part of the problem is that mothers lack vitamin D themselves, and are therefore unable to pass enough of the nutrient to their babies...
...growing around a long-line fishing vessel that sank in 1991, according to a report published in August in the journal PLoS One by Thierry Work, a wildlife-disease specialist at the U.S. Geological Survey, and his colleagues. The corallimorph were probably attracted to the leaching iron, a valuable nutrient in the sea, says Work. Since the organism, which sparsely populates other parts of the reef, grows fast, is aggressive and reproduces in three different ways, it outcompeted other marine life on the reef. "It's a carpet of living animals that destroyed all the other organisms underneath," said Work...
...with respect to the challenging circumstance that the soils of the Yard has had hundreds of years people walking on it.” The administration adopted Valkenburg’s proposal, creating the Harvard Yard Soils Restoration project that is based on the “natural, healthy nutrient cycling system.” This project represents a major shift from general landscape management, in which there is a heavy dependence on chemicals and artificial nitrogen sources. “We’ve been trained over the last 40 years that when there is a fungus infestation treat...
...Blooms are a natural phenomenon touched off a certain combination of nutrients in the water, and sunlight creates optimal growing conditions for algae - although they can be exacerbated by nutrient-rich runoff from farms, houses and factories. Thus far officials have downplayed the possibility of pollution as a factor in the Qingdao bloom. Wang Shulian, the deputy director of the Qingdao Oceanic and Fisheries Department, told reporters that there was no link to water quality, adding that the algae was aided by a combination of ideal temperature and salinity...
...that it's an easy one to fix. Most of the nutrient pollution that ends up in the Gulf comes from the hundreds of thousands of farms in the Midwest. The only sure way to shrink the dead zone is to reduce the amount of fertilizer running off those farms. But thanks in part to the push for corn-based ethanol and the skyrocketing price of food crops, U.S. farmers are planting more acres for corn than they have since World War II - including 15 million more acres last year than in 2006. Although there are measures farmers can take...
