I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
Science
“#Engineers find neat way to turn waste carbon dioxide into useful material” HR-TEM images for (a) ZnO-5, (b) ZnO-7 and (c) ZnO-9. Credit: Advanced Energy Materials (2020). DOI: 10.1002/aenm.202001381 Chemical engineers from UNSW Sydney have developed new technology that helps convert harmful carbon dioxide emissions into chemical building blocks to make useful industrial products like…
“#Passing challenging introductory chemistry course gives biggest boost to underrepresented students” Credit: CC0 Public Domain Studies have shown that students from certain backgrounds are less likely than their peers to complete an undergraduate degree in science, technology, engineering or mathematics—or STEM. These groups are low-income students, first-generation college students, female students and students from underrepresented…
“#Intracellular biopsy technique for fast microRNAs profiling in living cells” A scanning electron microscope (SEM) image shows the diamond nanoneedles penetrate the cell membrane. Credit: DOI: 10.1126/sciadv.aba4971 MicroRNAs (miRNAs) are gaining more attention in studies of human diseases such as cancer, because changes in miRNA expression are frequently associated with abnormal cellular functions. To achieve…
“#Molecular twist makes one catalyst useful for three hydrogen applications” By turning the red, blue, and green positions of one molecule like turning the steering wheel of a car, a single molecule developed by researchers in Japan can be turned into three types of catalysts for fuel cells, hydrogen production, or hydrogenation. The new insights…
“#Research team achieves massive sexual conversion of the malaria parasite in a dish” The technique will facilitate the design of new tools to block disease transmission Credit: Oriol Llorà Batlle/ISGlobal A research team at ISGlobal, an institution supported by the “la Caixa” Foundation, has developed a system to induce massive sexual conversion of the P….
“#Ancient bird figurine recovered from refuse heap the oldest instance of East Asian 3-D art” Photograph and 3D μ-CT reconstitution of the miniature bird figurine discovered at Lingjing (Henan Province, China), dated to 13 500 years ago. Credit: Francesco d’Errico and Luc Doyon A small bird carving—the oldest instance of East Asian three-dimensional art ever…
“#Island ‘drowning’ is not inevitable as sea levels rise” Islands in the Maldives – where sandy or gravel islands sit on top of coral reef platforms – are among those that could be affected by a global rise in sea levels. Credit: Gerd Masselink/University of Plymouth Coral reef islands across the world could naturally adapt…
“#Researchers mimic nature for fast, colorful 3-D printing” Inspired by nature, Illinois researchers developed synthetic structure-based color materials – like those found in chameleon skin — for polymer inks used in 3D printing. Credit: Diao Research Group. Brilliantly colored chameleons, butterflies, opals—and now some 3-D-printed materials—reflect color by using nanoscale structures called photonic crystals. A…

“#Acoustics put a fresh spin on electron transitions” Credit: Pixabay/CC0 Public Domain Electrons are very much at the mercy of magnetic fields, which scientists can manipulate to control the electrons and their angular momentum—i.e. their “spin.” A Cornell team led by Greg Fuchs, assistant professor of applied and engineering physics in the College of Engineering,…
