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

“#The Kerguelen oceanic plateau sheds light on the formation of continents” View of the Rallier du Baty peninsula in the vicinity of the Mont du Commandant, Kerguelen Islands. A pale-coloured rock, syenite, was injected into the basalts (which are darker), uplifting them. The king pengins give an idea of the scale. Credit: Michel de Saint…
“#Method to apply microfluidic electrochemical technologies to single-electron transfer redox-neutral reactions” Background and microfluidic redox-neutral electrochemistry (μRN-eChem). Credit: Science (2020). DOI: 10.1126/science.aba3823 A team of chemists and engineers at MIT has found a new way to apply microfluidic electrochemical technologies to single-electron transfer (SET) redox-neutral reactions. In their paper published in the journal Science, the…
“#Informal feedback: We crave it more than ever, and don’t care who it’s from” Credit: Shutterstock The COVID-19 crisis has changed the way many of us work. With the switch to working from home, in particular, a fundamental workplace behavior has gone by the wayside: informal feedback. At the office it is easy to get,…
“#ATLAS Experiment measures light scattering on light and constrains axion-like particles” Figure 1: Differential cross section of γγ→γγ production in lead–lead collisions at 5.02 TeV as a function of the invariant mass of the diphoton system and the cosine of the scattering angle in the photon-photon centre-of-mass frame, as measured by ATLAS. The measurements are…
“#Hot ring produces microwave-powered ultrasound pulses wirelessly” Thermoacoustic imaging of ultrasound wave generation from the split ring resonator, from Lan et al. 2020, Figure 3 (doi 10.1117/1.AP.2.3.036006) Credit: SPIE Ultrasound imaging is one of the workhorses in a modern hospital. It hits the trifecta of being relatively cheap, portable and non-invasive. Causing future parents to…
“#Matching-commitment agreements to incentivize climate action” Credit: CC0 Public Domain Many countries are failing to comply with the non-binding commitments of the Paris Agreement, making it increasingly clear that we have to reconsider how to ensure collective action to limit global warming to less than 2 degrees C above preindustrial levels. A new IIASA-led study…
“#Single-spin electron paramagnetic resonance spectrum with kilohertz spectral resolution” The comparison of the paramagnetic resonance spectrum between the traditional method (top) and the new method (bottom) of noise-insensitive. It clearly shows that the spectral resolution has been significantly improved, and more precise coupling information has been observed. Credit: DU Jiangfeng et al. A high-resolution paramagnetic…
“#Two-thirds of African Americans know someone mistreated by police, and 22% report mistreatment in past year” Credit: Tufts University Sixty-eight percent of African Americans say they know someone who has been unfairly stopped, searched, questioned, physically threatened or abused by the police, and 43% say they personally have had this experience—with 22% saying the mistreatment…
“#Researchers characterize Meissner corpuscles in mice” Anatomy and physiology of Meissner corpuscles required for tactile behavior. (A to C) Meissner corpuscles and their Aβ afferents (A) were required for normal tactile sensitivity (B) and fine sensorimotor control (C). (D) TrkB and Ret Aβ neurons both innervated Meissner corpuscles. (E and F) TrkB Meissner afferents were…
“#Despite clear skies during the pandemic, greenhouse gas emissions are still rising” Strict physical distancing restrictions have resulted in cleaner air, but atmospheric carbon dioxide levels continue to rise. Credit: PeteLinforth/Pixabay Physical distancing to prevent the spread of coronavirus has resulted in reports of reduced air pollution in some countries. However, this is not showing…
