Human-caused wildfire ignitions in Central Oregon are expected to remain steady over the next four decades and lightning-caused ignitions are expected to decline, but the average size of a blaze from either cause is expected to rise, Oregon State University modeling suggests.
While crop yield has achieved a substantial boost from nanotechnology in recent years, the alarms over the health risks posed by nanoparticles within fresh produce and grains have also increased. In particular, nanoparticles entering the soil through irrigation, fertilizers and other sources have raised concerns about whether plants absorb these minute particles enough to cause toxicity.
SUTD-led research has demonstrated a technology that allows users with camera phones to track the health of aquatic microorganisms -- assessing water quality and drinkability in the process.
Researchers at Karolinska Institutet in Sweden found industrial chemicals in the organs of fetuses conceived decades after many countries had banned the substances. In a study published in the journal Chemosphere, the researchers urge decision makers to consider the combined impact of the mix of chemicals that accumulate in people and nature.
An algorithm can predict when narwhals hunt - a task once nearly impossible to gain insight into. Mathematicians and computer scientists at the University of Copenhagen, together with marine biologists in Greenland, have made progress in gathering knowledge about this enigmatic Arctic whale at a time when climate change is pressuring them.
Olives are in high demand among plant breeders, owing to their characteristic flavor and the high-end oil derived from them. However, molecular techniques to enhance olive breeding is challenging, owing to a lack of high-quality genomic resources. To overcome this, a new study by Chinese researchers looked into a high-quality genome of a European olive variety and identified genes that can be used to enhance its taste, quality, and health benefits.
Diesel-polluted soil from now defunct military outposts in Greenland can be remediated using naturally occurring soil bacteria according to an extensive five-year experiment in Mestersvig, East Greenland, to which the University of Copenhagen has contributed.
Québec produces more strawberries than any other Canadian province. Strawberries are delicate and difficult to keep fresh. In response to this challenge, Monique Lacroix, a professor at INRS (l'Institut national de la recherche scientifique), and her team have developed a packaging film that can keep strawberries fresh for up to 12 days. The team's findings on how this film protects against mould and certain pathogenic bacteria have been published in Food Hydrocolloids.
Glyphosate is an herbicide commonly used in forestry operations throughout British Columbia, Canada. Researchers investigated how the chemical may affect the reproductive health of prickly wild rose, a perennial plant found beneath the forest canopy. The new study, by the open access publisher Frontiers, found that pollen viability decreased by an average of 66 percent compared to untreated plants a year after the herbicide was initially applied, with traces of glyphosate persisting for at least two years.
The new study, published in Global Environmental Change, found that both Europeans and Australians were highly concerned about the human health impact of marine plastic pollution, ranking it top of 16 marine-related threats in terms of cause for concern, including chemical or oil spills, marine biodiversity loss and climate change related effects such as sea-level rise and ocean acidification.
