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

“#Cell wall research reveals possibility of simple and sustainable method to protect crops” Arr6 cell wall alteration diagram. Credit: Antonio Molina While crop diseases have devastating consequences on agriculture, causing losses of up to 30% in some crops, plants constantly evolve to maintain robust immune systems that allow them to perceive pathogens and develop defenses….
“#Team develops benchmark for detecting large genetic mutations linked to major diseases” The ‘book analogy’ is a popular way of explaining genome changes. If the human genome is considered a book, a new NIST-developed benchmark will help scientists better detect large chapters that are missing (deleted chapters) or not in the original (inserted chapters).

“#Surprising growth rates discovered in world’s deepest photosynthetic corals” A colony of Leptoseris hawaiiensis at 315 feet in the Au’au Channel Hawaii. Credit: Hawaii Undersea Research Laboratory, University of Hawaii. New research published in the journal Coral Reefs revealed unexpectedly high growth rates for deep water photosynthetic corals. The study, led by Samuel Kahng, affiliate graduate faculty…
“#Why pulsars shine bright: A half-century-old mystery solved” The simulated density distribution of electron-positron plasma near the surface of a neutron star (shown in gray at the bottom of the plot). Redder regions represent a higher density of electron-positron pairs. Credit: A. Philippov et al./Physical Review Letters 2020 When Jocelyn Bell first observed the emissions…
“#Using Jenga to explain lithium-ion batteries” Credit: Unsplash/CC0 Public Domain Tower block games such as Jenga can be used to explain to schoolchildren how lithium-ion batteries work, meeting an educational need to better understand a power source that has become vital to everyday life. While lithium-ion batteries are abundant in so many of our electronic…
“#How teachers are adapting to COVID-19 disruptions is subject of new study” Noyce program researchers Meena Balgopal, Laura Sample McMeeking, DeeDee Wright and Andrea Weinberg, now studying how the COVID-19 pandemic has affected novice teachers. Credit: Colorado State University The COVID-19 pandemic has shone a spotlight on many of society’s unsung heroes—among them teachers, who took…
“#Excitons form superfluid in certain 2-D combos” Rice University theorists determined that certain combinations of weakly bound 2D materials let holes and electrons combine into excitons at the materials’ ground state. That combination can lead them to condense into a superfluidlike phase. The discovery shows promise for electronic, spintronic and quantum computing applications. Credit: Yakobson…
“#Radiation pressure with recoil: Experimental proof for a 90 year-old theory” Credit: CC0 Public Domain Light exerts a certain amount of pressure onto a body: sun sails could thus power space probes in the future. However, when light particles (photons) hit an individual molecule and knock out an electron, the molecule flies toward the light…
“#Electrically charged dust storms drive Martian chlorine cycle” Martian dust storm. Credit: NASA How’s the weather on Mars? Tough on rovers, but very good for generating and moving highly reactive chlorine compounds. New research from Washington University in St. Louis planetary scientists shows that Martian dust storms, like the one that eventually shut down the…
“#Black and female principal candidates more likely to experience delayed and denied promotions” Credit: CC0 Public Domain Black and female assistant principals are systematically delayed and denied promotion to principal, compared to their White or male counterparts, despite having equivalent qualifications and more experience on average, according to a new study. The findings were published…
