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

“#More than 1000 tons of plastic rains into western US protected lands annually” Researchers examined filters from field sites in several national parks and wilderness areas and did visual counts of microplastic beads and fragments deposited by wind and precipitation. The pennies are used to hold each filter in place on the microscope stage. Credit:…
“#Smallest cavity for light realized by graphene plasmons” Artistic illustration of the light compressed below the silver nanocubes randomly placed over the graphene-based heterostructure. Credit: Matteo Ceccanti Miniaturization has enabled technology like smartphones, health watches, medical probes and nano-satellites, all unthinkable a couple decades ago. Just imagine that in the course of 60 years, the…
“#Simulations reveal interplay between scent marking and disease spread” Credit: CC0 Public Domain In a new mathematical model that bridges animal movement and disease spread, territorial behaviors decreased the severity of potential disease outbreaks—but at the cost of increased disease persistence. Lauren White of the University of Maryland’s National Socio-Environmental Synthesis Center, Annapolis, MD, and…
“#Lab turns fluorescent tags into cancer killers” The design of thio-based photosensitizers, at left, by Rice University chemists shows promise for photodynamic cancer therapy, among other applications. One thiocarbonyl substitution — trading an oxygen atom for a sulfur atom — of a variety of fluorophores can dramatically enhance their ability to generate reactive oxygen species…
“#Pretty in pink: India crater lake changes colour overnight” India’s Lonar lake, which was formed 50,000 years ago after a meteorite hit Earth, has turned pink apparently, due to algae A crater lake in India’s western Maharashtra state has turned pink overnight, delighting nature enthusiasts and surprising experts who attributed it to changing salinity levels…
“#Plastic in the deep sea: Virtually unaltered after a quarter of a century” Credit: Peter Linke/GEOMAR Plastic products are durable. On one hand this is a great advantage, but on the other hand, if the plastic enters the environment, this advantage turns into a problem. According to current knowledge, natural degradation, as with organic matter,…
“#Ohio State University soil professor gets World Food Prize” In this undated photo provided by the World Food Prize Foundation, Rattan Lal, a professor of soil science at The Ohio State University poses at the University in Columbus, Ohio. Lai was named the recipient of the 2020 World Food Prize on Thursday, June 11, 2020….
“#Israeli scientists produce energy from plants” Israeli scientists say they have used algae to produce hydrogen Israeli scientists say they have produced hydrogen from plants in a development that they hope could eventually lead to using vegetation to produce electricity. The discovery was made by using microscopic algae, an aquatic plant, in research carried out…
“#The disease pyramid: Environment, pathogen, individual and microbiome” The microbiome is also an important part of the immune response in amphibians. Credit: Dirk Schmeller Researchers from the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB), the Université de Toulouse and the Helmholtz Centre for Environmental Research (UFZ) show how the microbial colonization of the organism…
“#Dopamine signaling allows neural circuits to generate coordinated behaviors” An image of a nematode captured by the team’s new microscope. The blue line is the worm’s centerline as reconstructed from a spline-based 14-parameter representation.
