Wine lovers may appreciate a dry white, but a lack of steady rainfall brought on by a changing climate is threatening a centuries old winemaking tradition in Italy, according to an international team of scientists.
A research team investigated the impact of extreme fires on previously intact carbon stores by studying the soil and vegetation of the boreal forest and how they changed after a record-setting fire season in the Northwest Territories in 2014. They collected 200 soil samples and used radiocarbon dating to estimate the carbon age. They found combustion of legacy carbon in nearly half of the samples taken from young forests (less than 60 years old).
Environmental DNA (eDNA) has successfully proven the presence of invasive crayfish in almost all the small streams around Lake Akan in Japan, suggesting that eDNA analysis is an efficient and highly sensitive method to assess the distribution of aquatic organisms.
New data showed that term, breastfed infants fed activated Bifidobacterium longum subsp. infantis EVC001 (B. infantis EVC001) experience improved metabolism of protein-bound glycans from human milk, compared to matched controls. Not only do these new data provide greater mechanistic understanding of how B. infantis selectively utilizes the glycans from human milk as growth substrate but may also provide a basis for facilitating B. infantis colonization in formula fed infants via utilization of bovine derived N-glycans.
Scientists have combined analyses from honey and salmon to show how lead from natural and industrial sources gets distributed throughout the environment. By analysing the relative presence of differing lead isotopes in honey and Pacific salmon, Vancouver-based scientists have been able to trace the sources of lead (and other metals) throughout the region. The research is being presented at the Goldschmidt conference in Barcelona.
Fiddler crabs see the polarization of light and this gives them the edge when it comes to spotting potentials threats, such as a rival crab or a predator. Now researchers at the University of Bristol have begun to unravel how this information is processed within the crab's brain. The study, published in Science Advances today, has discovered that when detecting approaching objects, fiddler crabs separate polarization and brightness information.
A good rainstorm can make a city feel clean and revitalized. However, the substances that wash off of buildings, streets and sidewalks and down storm drains might not be so refreshing. Now, researchers reporting in ACS' Environmental Science & Technology have analyzed untreated urban stormwater from 50 rainstorms across the US, finding a wide variety of contaminants that could potentially harm aquatic organisms in surface waters and infiltrate ground water.
Pathogenic bacteria that stubbornly lurk in some apple-packing facilities may be sheltered and protected by harmless bacteria that are known for their ability to form biofilms, according to Penn State researchers, who suggest the discovery could lead to development of alternative foodborne-pathogen-control strategies.
Study assembles canola root's dose-response curves for nitrogen sources.
Simple, fast and flexible: it could become significantly easier to vaccinate plants against viruses in future. Scientists at Martin Luther University Halle-Wittenberg (MLU), the Leibniz Institute of Plant Biochemistry (IPB) and the National Research Council in Italy (CNR) have developed a new method for this purpose. It enables the rapid identification and production of precisely tailored substances that combat different pathogens. The researchers discuss their work in the next edition of Nucleic Acids Research.
