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

“#The nature of nuclear forces imprinted in photons” by The Henryk Niewodniczanski Institute of Nuclear Physics Polish Academy of Sciences </p><div> <div> <div data-src=”https://scx2.b-cdn.net/gfx/news/hires/2020/thenatureofn.jpg” data-sub-html=”A two-dimensional map of the “quality of gamma line fit” surface (chi^2 surface) as a function of its transition energy Eγ and lifetime τ of the nuclear state studied. The surface…
“#Traffic density, wind and air stratification influence concentrations of air pollutant nitrogen dioxide” Credit: CC0 Public Domain In connection with the effects of the COVID-19 pandemic, satellite measurements made headlines showing how much the air pollutant nitrogen dioxide (NO2) had decreased in China and northern Italy. In Germany, traffic density is the most important factor….
“#Templating S100A9 amyloids on Aβ fibrillar surfaces revealed” AFM image of the amyloid templating of S100A9 fibrils on the surface of Aβ fibrils. Credit: Jonathan Pansieri A research team lead by Ludmilla Morozova Roche at Umeå University, Sweden, has provided the mechanistic insight into protein co-aggregation in Alzheimer’s disease. The templating mechanism of S100A9 amyloids…
“#An electrocatalyst for oxygen evolution reaction in water splitting” Atomic QTAIM basins of platinum and aluminium (transparent) and Al-Pt bond basin (red) in the Al2Pt compound, revealing the pronounced charge transfer from Al to Pt atoms and polar character of Al-Pt atomic interactions.

“#Scientists propose strategy for site-selective chiral drug synthesis in living systems” Credit: CC0 Public Domain Enantioselectivity plays an important role in the pharmacological and toxicological processes of chiral drugs. In chiral drug synthesis that uses bio-orthogonal chemistry within complex biological milieu, asymmetric transfer hydrogenation (ATH), which utilizes safe hydrogen donors instead of high pressure H2,…
“#Taste similarity of food products can be compared with the help of electroencephalography” Credit: Pixabay/CC0 Public Domain Marina Domracheva and Sofya Kulikova, researchers from HSE University’s campus in Perm, have discovered a new approach to analyze the perceived similarity of food products, based on electroencephalography (EEG) signals. They note that the power of gamma oscillations…
“#Global economic stability could be difficult to recover in the wake of the COVID-19, finds study” Credit: CC0 Public Domain Analysis from the University of Surrey suggests that the economies of countries such as America, the United Kingdom and Germany should prepare for a long slow recovery with prolonged periods of instability. Rates of growth…
“#Inferring the temperature structure of circumstellar disks from polarized emission” An ALMA submiilimeter image of the dusty circumstellar disc around a young star. Astronomers are using ALMA polarization maps of the radiation from discs simialr to this one to infer the presence of a temperature gradient, and infer possible accretion onto the disc. (The asterisk…
“#How conspiracy theories emerge—and how their storylines fall apart” Researchers produced a graphic representation of the narratives they analyzed, with layers for major subplots of each story, and lines connecting the key people, places and institutions within and among those layers. Credit: University of California, Los Angeles A new study by UCLA professors offers a…
“#Non-tobacco plant identified in ancient pipe for first time” Replica pipes used to experimentally “smoke” tobacco and other native plants in WSU laboratories for the study. The charred residue is then extracted, chemically “fingerprinted”, and compared to residue of ancient archaeological pipes.
