If you're technically inclined, here's a look at the references we used to construct these infographics: Facts About The Universe. Introduction: This interactive infographic from Number Sleuth accurately illustrates the scale of over 100 items within the observable universe ranging from galaxies to insects, nebulae and stars to molecules and atoms. While other sites have tried to magnify the universe, no one else has done so with real photographs and 3D renderings. How To Use: Credits:

DECOUVERTE. Une nouvelle espèce de grenouille, sosie de Kermit le Muppet
Kermit la grenouille existe-t-il vraiment ? Une grenouille longtemps passée inaperçu, mais qui est très particulière a été découverte et qui vue de face, on pourrait croire qu’elle aurait été le modèle de la célèbre marionnette des MuppetsNuage DECOUVERTE. Une nouvelle espèce de grenouille, sosie de Kermit le Muppet La grenouille découverte ressemble terriblement à Kermit. Par Morgane Kergoat La petite grenouille qui vient d’être découverte au Costa Rica vaut le coup d’œil. KERMIT. « Ses iris sont très blancs avec des taches ou réticulations fines et sombres« , décrivent B.Kubicki et ses collègues dans leur étude. Sa peau est d’un même vert-pomme, sauf vue de dessous. Hyalinobatrachium dianae a le ventre transparent comme du verre ©Kubicki et al. Enfin, cette petite grenouille – le mâle adulte mesure un peu moins de 30 mm de long – a une signature vocale bien particulière. WordPress: J’aime chargement…

Listen to an Earthquake’s Eerie ‘Whale Songs’
Is it possible to “hear” an earthquake? Not the rumbling of the ground that results, but the earthquake itself. Even if you could, what’s the point of listening? About a dozen years ago, geophysicist Ben Holtzman and musician/sound designer Jason Candler set out to answer these questions, with a side goal of sharing their passion for earthquakes with the public. From the fruits of their research, the SeismoDome show was born. Holtzman and Candler co-produce the show—with Holtzman writing scientific content, creating sounds from seismic data, and working with collaborators to produce the visual elements, while Candler handles the sound engineering and design and helps with the writing and conception of the show. When asked what listening to earthquakes can contribute to our knowledge of them, Holtzman explains how our subconscious factors in: “Humans perceive an enormous amount of information about physical processes through sound; we do it all the time, mostly subconsciously,” he says.
Solar System Scope
Cell Size and Scale
Some cells are visible to the unaided eye The smallest objects that the unaided human eye can see are about 0.1 mm long. That means that under the right conditions, you might be able to see an amoeba proteus, a human egg, and a paramecium without using magnification. Smaller cells are easily visible under a light microscope. To see anything smaller than 500 nm, you will need an electron microscope. Adenine The label on the nucleotide is not quite accurate. How can an X chromosome be nearly as big as the head of the sperm cell? No, this isn't a mistake. The X chromosome is shown here in a condensed state, as it would appear in a cell that's going through mitosis. A chromosome is made up of genetic material (one long piece of DNA) wrapped around structural support proteins (histones). Carbon The size of the carbon atom is based on its van der Waals radius.
NASA's Eyes: Eyes on the Solar System
Eyes on the Solar System lets you explore the planets, their moons, asteroids, comets and the spacecraft exploring them from 1950 to 2050. Ride with the Curiosity Rover as it lands on Mars or fly by Pluto with the New Horizons spacecraft all from the comfort of your home computer. Using real trajectory data you can recreate famous moments in solar system exploration, or preview exciting adventures yet to come. Fly with the Voyager spacecraft on their grand voyage, orbit Mars with MAVEN, fly by a comet with Deep Impact or Stardust, and observe our home planet alongside the spacecraft that keep track of Earth's climate. Want a quick dose of exciting exploration? Try the 'Simple' mode of Eyes on the Solar System to explore exciting destinations and missions and learn about the people involved in making it all happen. All these experiences are available on a Mac or PC by downloading NASA's Eyes. Credits Producers: Kevin Hussey, Stephen Kulczycki, and Alice Wessen Technical Director: Jason Craig
Curiosity Cabinet
Over the past 25 years I have accumulated a collection of various gizmos, devices, toys etc. which to me are excellent examples of scientific principles or things that you look at and you say "That's impossible!" except it's staring you in the face. In the hope that others may also find them interesting and with the help of two undergraduates, Jacy Lundberg and Omar Khan, we have created videos of many of the items in the collection. Jacy and Omar are currently seniors in the Boston College pre-medical program. In the olden days some people assembled what were known as curiosity cabinets.
