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.
Chinese researchers headed by Prof. CHEN Shengyun from the Northwest Institute of Eco-Environment and Resources (NIEER) and XUE Kai from University of Chinese Academy of Sciences have recently discovered links between reduction in microbial stability and soil carbon loss in the active layer of degraded alpine permafrost on the Qinghai-Tibet Plateau.
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.
Microplastic pollution of waterways has become a huge concern, with the tiny pieces of plastic entering food webs and potentially having harmful effects on animals and people. In addition, microplastics can act as breeding grounds for antibiotic-resistant bacteria. Now, researchers reporting in Environmental Science & Technology have analyzed antibiotic-resistance genes (ARGs) on five types of microplastics at different locations along the Beilun River in China, finding much higher abundances in urban than rural regions.
The biological and historical diversity in museum collections is staggering, with specimens collected across centuries by some of the most famous scientists in history. In a new study, researchers from the University of Copenhagen successfully revived museal fungal specimens that were more than 250 years old and used the live cultures for whole genome sequencing and physiological experiments.
Although stimulated-emission depletion (STED) microscopy was a true breakthrough for observing the morphology of live neurons at higher resolution, there is still room for improvement. In a recent study published in Neurophotonics, a team of scientists led by Dr. U. Valentin Nägerl from Université de Bordeaux developed a simple yet effective calibration method that allows for more precise STED imaging at higher tissue depths.
The human fetal immune system begins to develop early during gestation, however, factors responsible for fetal immune-priming remain elusive. Dr Florent Ginhoux from A*STAR's Singapore Immunology Network, Professor Jerry Chan from KK Women's and Children's Hospital, Professor Salvatore Albani from SingHealth Duke-NUS Translational Immunology Institute, and Cambridge University explored potential exposure to microbial agents in-utero. They identified live microbes across fetal organs that stimulate activation of fetal T-cells during the second trimester of gestation.
Just two weeks of citalopram exposure caused changes in crayfish behavior, with the potential to disrupt stream ecosystem processes like nutrient cycling, oxygen levels, and algal growth.
Viral genome sequencing of wastewater can provide an early warning system of emerging SARS-CoV-2 variants that is independent of investigations of identified clinical cases, according to a new study published in mSystems, an open-access journal of the American Society for Microbiology. In the study, researchers describe the detection and quantification of variant B.1.1.7, first identified in southeast England, in sewage samples from London, United Kingdom before widespread transmission of this variant was obvious from clinical cases.
State-of-the-art video microscopy has enabled Australian researchers to see the molecular details of how malaria parasites invade red blood cells - a key step in the disease.
