I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.

“#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,…
“#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…
“#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…
“#First confirmation of new theory by metamaterial” On the right, a unit cell cutout of the circuit board, which was built to demonstrate the non-Hermitian skin effect, is shown. In (a), the underlying theoretical non-Hermitian model is sketched, which describes the couplings between adjacent nodes. (b) depicts a schematic diagram of the full circuit chain…
“#What maritime shipping can learn from brain network science” Representation of the global liner shipping maritime network and its structural core. The color of the nodes corresponds to the ports belonging to different modular communities. Credit: Technische Universitaet Dresden Dr. Carlo Vittorio Cannistraci from TU Dresden’s Biotechnology Center (BIOTEC) is focusing his research on network…
“#Surprising features of mitochondrial protein synthesis uncovered” Credit: CC0 Public Domain Researchers at Karolinska Institutet have uncovered surprising features of mitochondrial protein synthesis. The study, published in Nature Communications, sheds light on the fundamental mechanisms used by the cell’s power plant. Mitochondria are essential organelles containing their own genome and the machinery for its expression….
