The study shows that sampling headwaters where streams form can identify which landscapes are resilient enough to handle the rigors of farming and which are vulnerable to leaching toxic residue into waterways.
Nitrogen-based synthetic fertilizer forms the backbone of the world food supply, but its manufacture requires a tremendous amount of energy. Now, computer modeling at Princeton University points to a method that could drastically cut the energy needed by using sunlight in the manufacturing process.
Scientists compared fecal samples from surfers and non-surfers to assess whether the surfers' guts contained E. coli bacteria that were able to grow in the presence of the antibiotic cefotaxime. Cefotaxime has previously been prescribed to kill off these bacteria, but some have acquired genes that enable them to survive this treatment. The study found that 13 of 143 (9 percent) of surfers were colonized by these resistant bacteria, compared to just four of 130 (3 percent) of non-surfers swabbed.
BfR Communication No. 036/2017 from 22 December 2017 Epidemiological studies are a central element of public discussion in the debate surrounding the carcinogenic potential of glyphosate. A publication that appeared in the USA in November examined whether there is a possible connection between the use of glyphosate containing plant protection products and cases of cancer among people who work in agriculture using a significantly broader data base.
Midwestern corn growers know the symptoms of northern corn leaf blight all too well: greenish-gray lesions on the leaves that can add up to major yield losses if not detected and treated early. Corn resistance genes have been identified, but the fungal disease has found ways to sneak around corn's defenses. Now, researchers have discovered how the fungus is outsmarting corn, and they may be able to use this information to help corn fight back.
The future of weeding is here, and it comes in the form of a robot. Specialty crops such as lettuce, broccoli, tomatoes, and onions may be the first to benefit.
A team of researchers led by Arizona State University and Google has assessed the value of urban agriculture and quantified its benefits at global scale. They report their findings in 'A Global Geospatial Ecosystems Services Estimate of Urban Agriculture,' in the current issue of Earth's Future.
In one of the first analyses of a company-led sustainability program in the food and agriculture space, Stanford researchers found a major grocery chain fostered increased adoption of environmental practices at the farm level.
When given the choice, honey bee foragers prefer to collect sugar syrup laced with the fungicide chlorothalonil over sugar syrup alone, researchers report in the journal Scientific Reports.
A University of Maryland-led study is the first to assess long-term changes in freshwater salinity and pH at the continental scale. Drawn from data recorded at 232 USGS monitoring sites across the country over the past 50 years, the analysis shows significant increases in both salinization and alkalinization. The results also suggest a close link between the two properties, with different salt compounds combining to do more damage than any one salt on its own.
