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

“#Beneath the surface of our galaxy’s water worlds” This artist’s concept shows a hypothetical planet covered in water around the binary star system of Kepler-35A and B. The composition of such water worlds has fascinated astronomers and astrophysicists for years. Credit: NASA/JPL-Caltech Out beyond our solar system, visible only as the smallest dot in space…
“#Self-powered alarm fights forest fires, monitors environment” Credit: CC0 Public Domain Smokey the Bear says that only you can prevent wildfires, but what if Smokey had a high-tech backup? In a new study, a team of Michigan State University scientists designed and fabricated a remote forest fire detection and alarm system powered by nothing but…
“#Simulations reveal how saltwater behaves in Earth’s mantle” An artist’s depiction of highly compressed saltwater at high temperature. Credit: Zhang et al Scientists estimate that the Earth’s mantle holds as much water as all the oceans on the planet, but understanding how this water behaves is difficult. Water in the mantle exists under high pressure…
“#New process could safeguard water quality, environment and health” Samples being placed into a centrifuge to separate sample components. Credit: Swansea University A research team at Swansea University have developed a new method for fast removal and detection of wastewater pollutants that come from everyday pharmaceuticals like paracetamol, ibuprofen and aspirin, which could help minimise…
“#New microscopy under ambient achieves less than 10 nm spatial resolution on surface potential measurement” Credit: ACS A new nanomaterials microscopy approach called Pulsed Force Kelvin Probe Force Microscopy (PF-KPFM), allows for less than 10 nanometer measurements of work function and surface potential in a single-pass AFM scan. The findings have been published in two…
“#Puget Sound eelgrass beds create a ‘halo’ with fewer harmful algae, new method shows” A study site at the southern tip of Hood Canal, on the shore of the Skokomish Indian Tribe land, in summer 2018. Eelgrass can be seen just below the water’s surface. Credit: Emily Kunselman Eelgrass, a species of seagrass named for…
“#Effects from low-level concentrations of harmful chemicals preserved in three generations of fish” Inland silverslide. Credit: Oregon State University Fish exposed to very low levels of chemicals commonly found in waterways can pass the impacts on to future generations that were never directly exposed to the chemicals, according to Oregon State University researchers. “What that…
“#Plug-and-play lens simplifies adaptive optics for microscopy” Researchers have developed a new plug-and-play lens that can add adaptive optics correction to commercial optical microscopes. The image shows a section of mouse brain acquired with a light sheet microscope and corrected with the adaptive lens. Credit: T. Furieri (CNR-IFN), G. Calisei and A. Bassi (Politecnico of…
“#Rogue’s gallery of dusty star systems reveals exoplanet nurseries” This figure shows the dust rings around young stars captured by the Gemini Planet Imager Exoplanet Survey, or GPIES. The rings show a diversity of shapes and sizes, made more extreme by the different projections of the rings on the sky. Credit: UC Berkeley image by…
“#Resident parasites influence appearance, evolution of barn swallows” A barn swallow in the Czech Republic stares inquisitively at the camera. Credit: Amanda Hund Barn swallows live almost everywhere on the planet, recognizable by their forked tail and agility in the air. Yet while they share these characteristics, these little birds often look slightly different in…
