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

“#Fishing for a theory of emergent behavior” The classification from Φ values related to the school’s behaviour. (a) analysis of 2-fish schools. (b) analysis of 3-fish schools. (c) analysis of 4-fish schools. (d) analysis of 5-fish schools. Credit: University of Tsukuba Researchers at the University of Tsukuba used advanced metrics from information theory to describe…
“#Shining light into the dark: New discovery makes microscopic imaging possible in dark conditions” Controlling chemiluminescence in two dimensions. Credit: Dr Yan Vogel, Curtin University Curtin University researchers have discovered a new way to more accurately analyze microscopic samples by essentially making them glow in the dark through the use of chemically luminescent molecules. Lead…
“#Study: Hospital security guards employ excessive physical violence, require training” Credit: Pixabay/CC0 Public Domain Security guards employed at hospitals may be ill-prepared to deal with Code Black situations where patients or visitors appear threatening or violent, says Flinders University Professor of Nursing (Mental Health) Eimear Muir-Cochrane. A study of medical and surgical wards in a…
“#New comet NEOWISE graces the skies” Comet NEOWISE captured on July 6, 2020 above the northeast horizon just before sunrise in Tucson. Viewers in the region can find the comet in the northeastern sky near the horizon between 4 and 4:30 a.m. until July 11, after which it will be visible in the northwestern sky…
“#Novel ‘dual-resonant method’ in 2-D materials can spur advances in the field of photonics” Photonics, the science of manipulating light, can lead to the development of advanced optical devices, but the efficient generation of photons has remained a challenge until now.

“#Scientists look to bird feathers for printing colors” Structural colors are colors that are reflected when microscopic surfaces interfere with visible light. On the peacock, for example, tail feathers have brown pigment, or melanin, but their microscopic structure makes them reflect the dazzling colors we typically see in peacocks — blue, green and turquoise.

“#Biologists trace plants’ steady mitochondrial genomes to a gene found in viruses, bacteria” Arabidopsis plant that lacks functional copies of MSH1. Researchers investigated the role of this gene in mitochondrial genome stability. Credit: Colorado State University One could say that mitochondria, the energy-producing organelles inside every human cell, dance to their own beat. After all,…
“#New report sheds light on the impact of COVID-19 on gender and sustainability” Credit: Pixabay/CC0 Public Domain Professor Sophie Harman from Queen Mary’s School of Politics and International Relations was one of the lead authors on a major new report from U.N. Women, the United Nations organization dedicated to gender equality and the empowerment of…
“#Supermassive binary black hole hunter: SKA pulsar timing array” The red curve cross the contour centers shows the evolution trend of SMBBH population from low redshift to high redshift: the gravitational wave frequencies increase; the gravitational wave strains decrease first and then increase.

“#The spin state story: Observation of the quantum spin liquid state in novel material” A QSL state can be experimentally observed, which has advanced our knowledge of spin behavior, and its integration in next-generation “spintronic” devices. Credit: Tokyo University of Science Aside from the deep understanding of the natural world that quantum physics theory offers,…
