I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#This molecule helps sweet-toothed protein complex sense sugar” Credit: Steven Lee/Whitehead Institute In order to grow and thrive, cells need sugar. A repertoire of cellular mechanisms turn unwieldy molecules of glucose and fructose into versatile building blocks for making useful molecules such as lipids, and energy to fuel necessary processes in the cell. But for…
“#Researchers find therapeutic targets to fight SARS-CoV-2” Joint distribution of significant hsa-miR-125a-5p / ACE2 andhsa-miR-199-5p / TMPRSS2 interactions in different organs. Light blueregions correspond to 95% confidence intervals. Credit: Nersisyan, et. al. Researchers from HSE University have developed new approaches for regulating the expression of ACE2 and TMPRSS2 enzymes, which play a crucial role in…
“#Researchers discover ‘Marie Kondo’ protein which aids in organizing fruit fly embryos” Credit: CC0 Public Domain Researchers at the University of Colorado School of Medicine have discovered a protein in fruit fly embryos, dubbed Marie Kondo, that destroys maternal proteins. Much like namesake, author and clutter consultant Marie Kondo, this gene removes unnecessary molecules, keeping…
“#The big gulp: Inside-out protection of parasitic worms against host defenses” This confocal image shows a juvenile female schistosome, a parasitic flatworm that infects hundreds of millions of people globally, causing the disease schistosomiasis. The species shown here, Schistosoma mansoni, lives inside host blood vessels, where it takes up nutrients that fuel its growth and…
“#Machine learning reveals recipe for building artificial proteins” Credit: Unsplash/CC0 Public Domain Proteins are essential to the life of cells, carrying out complex tasks and catalyzing chemical reactions. Scientists and engineers have long sought to harness this power by designing artificial proteins that can perform new tasks, like treat disease, capture carbon, or harvest energy,…
“#Researchers use cell imaging and mathematical modeling to understand cancer progression” A tetraploid RPE-1 mitotic cell. Centrioles are displayed in green (two dots at each centrosome/spindle pole); microtubules are displayed in red; chromosomes are displayed in blue. The image was acquired on a wide-field fluorescence microscope. Credit: Daniela Cimini for Virginia Tech Cell division is…
“#Map of ammonium’s journey ‘could prevent infection’” Credit: University of Strathclyde, Glasgow The mechanism of a protein which transports ammonium across cell membranes has been discovered in research led at the University of Strathclyde, which could lay the foundations for preventing infection. The transporting process is vital to all living things but in two distinct…
“#’Self-eating’ process of stem cells may be the key to new regenerative therapies” Credit: CC0 Public Domain The self-eating process in embryonic stem cells known as chaperone-mediated autophagy (CMA) and a related metabolite may serve as promising new therapeutic targets to repair or regenerate damaged cells and organs, Penn Medicine researchers show in a new…
“#Scientists appeal for public help with climate change technology project” Credit: CC0 Public Domain Citizen scientists are being asked to play a role in developing cutting edge imaging technologies that will help us understand the effects of major threats to biodiversity. Through the EmbryoPhenomics project, researchers at the University of Plymouth are applying bioimaging, robotics…
“#The genome of the phylloxera that devastated European vines in the nineteenth century, deciphered” Credit: CC0 Public Domain The genome of the phylloxera, an insect that caused plagues that devastated European vines in the 19th century, has been deciphered by an international team involving researchers Miquel Barberà and David Martínez, from the Institute for Integrative…
