I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Calcium helps build strong cells” Credit: Carnegie Mellon University, Department of Chemical Engineering Every time you flex your bicep or stretch your calf muscle, you put your cells under stress. Every move we make throughout the day causes our cells to stretch and deform. But this cellular deformation can be dangerous, and could potentially lead…
“#Biologists unravel tangled mystery of plant cell growth” Scanning electron micrographs of maize plant cells. Wild-type (left), and the TANGLED1 mutant (RIGHT). Credit: Carolyn Rasmussen/UCR When cells don’t divide into proper copies of themselves, living things fail to grow as they should. For the first time, scientists now understand how a protein called TANGLED1 can…
“#Cell removal as the result of a mechanical instability” Figure 1. Schematic illustration of cell extrusion from epithelial tissue. Credit: Kanazawa University Researchers at Kanazawa University report in the Biophysical Journal that the process of cell removal from an epithelial layer follows from an inherent mechanical instability. Moreover, the forces generated by an extruding cell…
“#’Like a tunnel for cholesterol’: Scientists show how ‘bad’ cholesterol gets into cells” Artist’s impression of cholesterol stored in fat cells. Credit: Shutterstock Scientists have shown for the first time how two proteins provide a tunnel for so-called bad cholesterol to enter our body cells. The finding—conducted on cell lines in the lab—has implications for…
“#Researchers identify key steps in development of kidneys” Credit: CC0 Public Domain The discovery of how certain key structures in the kidneys are formed could have important implications for treating renal fibrosis (or scarring), a feature of chronic kidney disease (CKD), according to a new study by a researcher at Massachusetts General Hospital (MGH). Interestingly,…
“#Gut bacteria may modify behavior in worms, influencing eating habits” Photo of a researcher using a pipette in the lab.

According to a new study in Nature, specific gut bacteria…
“#’Relaxed’ T cells critical to immune response” Rice University scientists’ simple model of T cell activation of the immune response shows the T cell binding, via a receptor (TCR) to an antigen-presenting cell (APC). If an invader is identified as such, the response is activated, but only if the “relaxation” time of the binding is…
“#New research investigates the role of lipid rafts in virus infiltration” Credit: CC0 Public Domain A cell’s membrane acts as a natural shield, a fence around the cell that protects and contains it. It mediates processes that let nutrients through and let waste out, and it acts as a physical barrier to the entry of…
“#An ion channel senses cell swelling and helps cells to choose a response” Credit: CC0 Public Domain After a dry spell, a rainy day can feel rejuvenating. But for plants, a downpour can mean trouble. Faced with water suddenly rushing into its tissues, a plant must control its cells’ volume or risk them exploding. New…
“#Research team achieves massive sexual conversion of the malaria parasite in a dish” The technique will facilitate the design of new tools to block disease transmission Credit: Oriol Llorà Batlle/ISGlobal A research team at ISGlobal, an institution supported by the “la Caixa” Foundation, has developed a system to induce massive sexual conversion of the P….
