“#COVID-19 antibody tests: How reliable are they?” Credit: CC0 Public Domain With stay-at-home orders expiring around the world, many hope that COVID-19 antibody testing will help businesses and institutions reopen safely. Determining whether people have been infected with SARS-CoV-2 is a key tool in responding to the pandemic, but it is not a magic bullet….
“#Will lockdown loneliness make us loners?” Zebrafish raised in isolation display different social preferences from those raised normally. Credit: Tunbak et al 2020 Over the past few months at least half of the world’s population has been affected by some form of lockdown due to COVID-19, and many of us are experiencing the impact of…
“#Potential high-risk clones identified among S. maltophilia strains in European hospitals” Credit: CC0 Public Domain Stenotrophomonas maltophilia are increasingly recognized as significant opportunistic pathogens in healthcare settings worldwide, the global spread of multidrug-resistant strains of this species being the most serious concern. Epidemiological studies are important to identify particular lineages or strains exhibiting clinically relevant…
“#Considering health when switching to cleaner electricity” Credit: American Chemical Society Power plants that burn coal and other fossil fuels emit not only planet-warming carbon dioxide, but also pollutants linked to breathing problems and premature death. Policies proposed to mitigate climate change, however, often fail to fully account for the health benefit of switching to…
“#Team develops online atlas of human immunome for precision medicine” Credit: CC0 Public Domain Scientists from the SingHealth Duke-NUS Academic Medical Centre (AMC) have developed an interactive web-based atlas of the human immunome, or genes and proteins that make up the immune system. Known as EPIC (Extended Polydimensional Immunome Characterisation), the atlas hosts a comprehensive,…
“#Cellular stress causes cancer cell chemoresistance” Dissecting the UPR-response with multi-omics approaches, UPR-response is depicted at cellular level red. Credit: © Robert Ahrends There is a broad range of mechanisms associated with chemoresistance, many of which to date are only poorly understood. The so-called cellular stress response—a set of genetic programs that enable the cells…
“#Microplastic background pollution in the Curonian Spit beach” An article written by an international team of scientists was published recently in Marine Pollution Bulletin magazine. The team included representatives of the Russian Academy of Sciences Shirshov Institute of Oceanology Atlantic Department, the Immanuel Kant Baltic Federal University, and the Institute of Baltic Sea Research (Warnemunde,…
“#Clostridioides difficile captures blood cell cofactor to build defensive shield” This photograph depicts Clostridium difficile colonies after 48hrs growth on a blood agar plate; Magnified 4.8X. C. difficile, an anaerobic gram-positive rod, is the most frequently identified cause of antibiotic-associated diarrhea (AAD). It accounts for approximately 15-25% of all episodes of AAD.

“#Simulations on biologically relevant time scales achieved” Credit: CC0 Public Domain Molecular dynamics simulations (MD) have become a ubiquitous tool in modern life sciences. In these simulations, the interactions between atoms and molecules and their resulting spatial movements are iteratively calculated and analyzed. Scientists are currently trying to gain access to biologically relevant length and…
“#Antarctic sea-ice models improve for the next IPCC report” A thin layer of Antarctic sea ice. The ice first forms in round disks, known as “pancake ice.” Credit: Lettie Roach/University of Washington The world of climate modeling is complex, requiring an enormous amount of coordination and collaboration to produce. Models feed on mountains of different…
