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

“#Q&A: Protecting essential farm workers during COVID-19” Credit: CC0 Public Domain State and federal executive orders have deemed seasonal and migrant farmworkers “essential.” Yet, few protections have been granted to this population, which may be at higher risk of exposure to coronavirus, according to a policy brief by researchers at the University of Michigan School…
“#Fuel walking and cycling with low carbon diets, researchers say” Credit: Pixabay/CC0 Public Domain Walking and cycling have many benefits and help reduce greenhouse gas emissions, but researchers say we need to think about what people eat to fuel their walking and cycling. In a paper published in the international journal, Scientific Reports, the researchers…
“#Quantum effect observed in ‘large’ metal” Credit: EPFL/QMAT In the world of materials science, sometimes main discoveries can be found in unexpected places. While working on the resistivity of a type of delafossite—PdCoO2—researchers at EPFL’s Laboratory of Quantum Materials discovered that the electrons in their sample did not behave entirely as expected. When a magnetic…
“#Precise magnets 3-D printed from special stainless steel” Empa Precisely Magnetized: Iron filings stick to this mini chessboard with four millimeter edge length. The partially magnetic structure was produces from a single type of steel power at different temperatures. Credit: Swiss Federal Laboratories for Materials Science and Technology It looks quite inconspicuous to the casual…
“#Using GIE to map deforestation in the Amazon rainforest” Credit: CC0 Public Domain As deforestation continues to rise in the Amazon rainforest, efforts are ongoing to identify ways to reverse the trend of tree loss in this valuable ecosystem. One example is land titling, land reform that grants private individuals and families formal property rights…
“#Chinese conservationists battle to save pangolins from poachers” The pangolin was found in a fishpond by a farmer and brought to the government-run rescue centre in Jinhua Rescued from a farmer’s fishpond, a young pangolin’s release back into China’s wilderness this week was hailed as a small victory in the battle to save the critically…
“#Potential beginning of life simulated in lab” High-pressure for evolutionary experiments. Credit: C. Mayer Did life originate underground? Scientists at the University of Duisburg-Essen (UDE) have substantiated their theory that life could have begun deep in the Earth’s crust. In their experiments, structures that were inanimate developed survival strategies within a short time. In the…
“#Lives saved or deaths postponed? Calculating the cost of lockdowns” Credit: Pixabay/CC0 Public Domain While lockdowns undoubtedly avoided large numbers of deaths from the new coronavirus, the repercussions of the pandemic response are expected to blight economies and health systems long after restrictions are lifted. So how can we quantify the costs and benefits of…
“#Minimizing thermal conductivity of crystalline material with optimal nanostructure” The optimum nanostructure designed with MI (aperiodic superlattice structure) was actually fabricated, and the optimal performance was verified by assessing its thermal conductivity. Figure: the Actual Structure is the electron microscope image of the fabricated sample. In addition, by further analyzing the phonon transport in the…
“#The coastal banksia has its roots in ancient Gondwana” Credit: John Tann/Flickr, CC BY If you fondly remember May Gibbs’s Gumnut Baby stories about the adventures of Snugglepot and Cuddlepie, you may also remember the villainous Big Bad Banksia Men (perhaps you’re still having nightmares about them). But banksias are nothing to be afraid of….
