I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Building mechanical memory boards using origami” Origami-inspired binary switches. Credit: R. Masana The ancient Japanese art of paper folding, known as origami, can be used to create mechanical, binary switches. In Applied Physics Letters, researchers report the fabrication of such a paper device using a particular origami pattern known as the Kresling pattern. This device…
“#New method to track ultrafast change of magnetic state” In the new study together with their international colleagues, Professor Dr Dmitry Turchinovich (left) and Wentao Zhang demonstrate how the ultrafast change of magnetic states can be measured.

“#A new generation of synchrotron” EMBL scientists in the process of upgrading MASSIF-1 in installing the EMBL microdiffractometer. Credit: Matthew Bowler/EMBL Inside the European Synchrotron Radiation Facility’s 844-meter-diameter storage ring, electrons traveling at almost the speed of light produce some of the brightest X-ray beams in the world. These X-rays can reveal the position and…
“#Less flocking behaviour among microorganisms reduces the risk of being eaten” Credit: CC0 Public Domain When algae and bacteria with different swimming gaits gather in large groups, their flocking behavior diminishes, something that may reduce the risk of falling victim to aquatic predators. This finding is presented in an international study led from Lund University…
“#Ocean hitchhiker’s sucker mechanism offers potential for underwater adhesion” A remora. Credit: NOAA CCMA Biogeography Team/Wikipedia A new study has revealed how remora suckerfish detach themselves from the surfaces they’ve clung to—and how the mechanism could provide inspiration for future reversible underwater adhesion devices. The research, by an international, multidisciplinary team working across robotics, comparative…
“#Physics team applies quantitative methods to model how far virus-laden aerosols travel through the air” Credit: University of Florida As scientific voids go, it would be hard just now to find a more pressing question: How do the aerosols that carry the invisible coronavirus travel on the air after they leave an infected person? Is…
“#Researchers discover first ‘open-charm’ tetraquark” The band associated with the new tetraquark transforming into a D− and a K at a mass of 2.9 GeVc2. Credit: HCb Collaboration/CERN The LHCb experiment at CERN has developed a penchant for finding exotic combinations of quarks, the elementary particles that come together to give us composite particles such…
“#Self-excited dancing droplets” This self-propelled droplet platform could be used for self-cleaning surfaces and other applications. Credit: Harvard SEAS Controlling the movement of liquid droplets is important in many applications that generate heat, from power plant condensers to personal computers. Techniques to control droplets on surfaces today include using good old-fashioned gravity, hydrophobic chemical coatings,…
“#Searching for supernova neutrinos with Deep Underground Neutrino Experiment” DUNE scientists will study streams of neutrinos emitted by exploding stars. DUNE’s unique strength is its sensitivity to a particular type of neutrino called the electron neutrino, which will provide scientists with supernova data not available from any other experiment. Credit: Fermilab When a massive star…
“#Calculating hadrons using supercomputers” Antoni Woss has been awarded the 2019 JSA Thesis Prize for for exploring the theory underpinning the properties of subatomic particles and how they can decay. Credit: Antoni Woss Hadrons are elusive superstars of the subatomic world, making up almost all visible matter, and British theoretical physicist Antoni Woss has worked…
