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

“#Teaching physics to neural networks removes ‘chaos blindness’” The Hamiltonian flow represented as a donut-like torus; rainbow colors code a fourth dimension. Credit: North Carolina State University Researchers from North Carolina State University have discovered that teaching physics to neural networks enables those networks to better adapt to chaos within their environment. The work has…
“#Video: How tear gas affects your body” Credit: The American Chemical Society 2-Chlorobenzalmalononitrile, better known as CS gas, is one of the most common tear gases used in the United States today, but did you know it’s not actually a gas? We break down how it works, a bit of its history and the best…
“#A new social role for echolocation in bats that hunt together” The research team tested whether M. molossus can use echolocation calls to discriminate among different group members. Credit: Irene Mendez Cruz Searching for food at night can be tricky. To find prey in the dark, bats use echolocation, their “sixth sense.” But to find…
“#Ancient societies hold lessons for modern cities” 3D reconstruction of a Northern Rio Grande Pueblo community dating to the 14th century CE based on unmanned aerial vehicle survey.

“#NASA observes large Saharan dust plume over Atlantic ocean” On June 18, 2020, NASA-NOAA’s Suomi NPP satellite captured this visible image of the large light brown plume of Saharan dust over the North Atlantic Ocean. The image showed that the dust from Africa’s west coast extended almost to the Lesser Antilles in the eastern North…
“#Polymers can fine-tune attractions between suspended nanocubes” Colloids are complex mixtures in which microscopic particles of one substance are suspended evenly throughout another. They can be prepared in many different ways, but to achieve desirable properties in the final mixture, researchers must maintain a delicate control over the interactions which take place between the particles….
“#Is teleportation possible? Yes, in the quantum world” A quantum processor semiconductor chip is connected to a circuit board in the lab of John Nichol, an assistant professor of physics at the University of Rochester. Nichol and Andrew Jordan, a professor of physics, are exploring new ways of creating quantum-mechanical interactions between distant electrons, promising…
“#Fantastic muscle proteins and where to find them” Watching the sarcomeres contract — collage of myosin (green), actin and the Z-disk (red) and BioID (blue). Credit: Jacobo Lopez Carballo, Gotthardt Lab, MDC Researchers at the Max Delbrück Center for Molecular Medicine in the Helmholtz Association (MDC) developed a mouse model that enables them to look…
“#Researchers study a novel type of extracellular vesicles” Isolation of liquid-phase EV and MBV. (A) SEM images of an ECM scaffold derived from urinary bladder matrix (UBM) showing discrete spherical bodies approximately 100 nm in diameter dispersed throughout the matrix. Scale bars, 1 μm. (B) Illustration of the 3T3 fibroblast cell culture model used to…
“#We caught bacteria from the most pristine air on earth to help solve a climate modeling mystery” Not all clouds are the same, and climate models have been predicting the wrong kinds of clouds over the Southern Ocean. Credit: Kathryn Moore, CC BY-ND The Southern Ocean is a vast band of open water that encircles…
