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

“#Success begets success in crowdfunding—but so does falling just short, study shows” Kickstarter campaigns that fall just short of their funding goal may make backers more keen to support similar ideas than campaigns that are moderately successful, according to a recent U of A study.

“#Liquid metal synthesis for better piezoelectrics: Atomically-thin tin-monosulfide” Output voltage in a practical, wearable device: voltage output during tensile bending and relaxing (two-electrode device). Credit: FLEET An RMIT-UNSW collaboration has applied liquid-metal synthesis to piezoelectrics, advancing future flexible, wearable electronics, and biosensors drawing their power from the body’s movements. Materials such as atomically thin tin-monosulfide…
“#Best evidence yet for existence of anyons” Quasiparticle braiding experiment. a) Schematic representation of quasiparticle exchange; quasiparticles are represented by red vortices, and trajectories are shown in dashed lines. b) False-color SEM image of interferometer. Credit: arXiv:2006.14115 [cond-mat.mes-hall] A small team of researchers at Purdue University has found the strongest evidence yet of the existence…
“#Reducing the operating temperature of ceramic fuel cells with a high proton conductivity electrolyte” Design of the NCO/CeO2 heterostructure functionalities for fast proton migration. Credit: Science (2020). DOI: 10.1126/science.aaz9139 A team of researchers affiliated with several institutions in China has developed a way to reduce the operating temperature of ceramic fuel cells by using a…
“#Cause of oversized placentas in cloning found after two decades” Figure 1: A mouse embryo (left) produced by somatic cell nuclear transfer (SCNT) attached to a normalized placenta (right). RIKEN researchers have discovered why SCNT produces large placentas. Credit: RIKEN BioResource Research Center One reason a technique for cloning animals often results in oversized placentas,…
“#By 2025, carbon dioxide levels in Earth’s atmosphere will be higher than at any time in the last 3.3 million years” The composition of fossilised zooplankton shells has enabled the reconstruction of past pH and CO2. Credit: University of Southampton By 2025, atmospheric carbon dioxide (CO2) levels will very likely be higher than they were…
“#Meet baker’s yeast, the budding, single-celled fungus that fluffs your bread” Baker’s yeast, Saccharomyces cerevisiae, proofing with sugar and water in a 40-minute time-lapse animation. Credit: Douglas Levere / University at Buffalo They live in bread dough. They die in your oven. At the grocery store, where you buy them, they sit in little glass…
“#Research on seawater surface tension becomes international guideline” Surface tension is the property of water that enables bugs to skim the surface of water. Research by John Lienhard and Kishor Nayar to understand how the surface tension of seawater changes with temperature and salinity has become an international standard. Credit: Christopher Paul High The property…
“#To engineers’ surprise, radiation can slow corrosion of some materials” These optical and scanning electron microscope images show irradiated and unirradiated zones of a nickel-chromium alloy. The left side shows examples of foils with irradiation; instead of degrading the material as it almost always does, the radiation actually makes it stronger by reducing the rate…
“#The WHO often has been under fire, but no nation has ever moved to sever ties with it” Credit: CC0 Public Domain In the midst of a surge of new cases of COVID-19, the United States this week gave formal notice of its intention to withdraw from the World Health Organization. The move, to take effect…
