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

“#Why nature, history and American culture all make social isolation difficult” Credit: CC0 Public Domain As politicians consider ways to stem the rising number of COVID-19 cases, public spaces have become battlegrounds for those tired of the closures. But the controversy has roots deeper than political or economic interests—social isolation is mentally and emotionally taxing….
“#A new understanding of protein movement” A team of engineers has shown that surface diffusion in protein transport into ion-exchange beads depends on adsorption affinity — a measure of attraction between the two materials. Credit: University of Delaware Many of the most promising medicines under development are proteins, often antibodies, to help patients fight disease….
“#Scientists use nanoparticle-delivered gene therapy to inhibit blinding eye disease in rodents” In experiments in rats and mice, two Johns Hopkins scientists — an engineer and an ophthalmologist — report the successful use of nanoparticles to deliver gene therapy for blinding eye disease. A uniquely engineered large molecule allows researchers to compact large bundles of…
“#High-throughput sequencing tracks historical spread of grapevine viruses” Credit: CC0 Public Domain Grapevine is infected by more than 90 viruses, with new viral species discovered yearly as a result of the newer technology introduced by High-Throughput Sequencing (HTS). Within the last decade, HTS is used for virome identification (the assemblage of viral genomes), which in…
“#RNA key in helping stem cells know what to become” Credit: CC0 Public Domain Look deep inside our cells, and you’ll find that each has an identical genome -a complete set of genes that provides the instructions for our cells’ form and function. But if each blueprint is identical, why does an eye cell look…
“#New collection of stars, not born in our galaxy, discovered in Milky Way” Still from a simulation of individual galaxies forming, starting at a time when the Universe was just a few million years old. Credit: Hopkins Research Group, Caltech Astronomers can go their whole career without finding a new object in the sky. But…
“#NASA finds powerful storm’s around Tropical Storm Cristina’s center” On July 7 at 4:10 a.m. EDT (0810 UTC) the MODIS instrument that flies aboard NASA’s Aqua satellite revealed two areas of very powerful thunderstorms (yellow) around Cristina’s center where cloud top temperatures were as cold as minus 80 degrees Fahrenheit (minus 62.2 Celsius).

“#Contest between superconductivity and insulating states in ‘magic angle’ graphene” Close-up of the device (the twisted bilayer graphene structure is in the black center region on both squares with gold borders). This device is placed on the experimental setup within the fridge. Credit: ICFO If you stack two layers of graphene one on top of…
“#Edouard now post-tropical in NASA-NOAA satellite imagery” On July 6, NASA-NOAA’s Suomi NPP satellite provided a visible image of Post-Tropical Cyclone Edouard merging with a frontal boundary in the Northern Atlantic Ocean.

“#’Growing’ active sites on quantum dots for robust hydrogen photogeneration” Schematic diagram of site- and spatial- selective integration of metal ions into QDs for robust H2 photogeneration. Credit: Prof. WU’s Group Very recently, Chinese researchers had achieved site- and spatial- selective integration of earth-abundant metal ions (e.g., Fe2 , Co2 , Ni2 ) in semiconductor…
