Le Sentier des Exoplanètes - Astropléiades, Les Pléiades, Suisse Pour prolonger la découverte de l'espace, choisissez le chemin pédestre "Le Sentier des Exoplanètes". Tout au long du parcours, vous trouverez dix bornes en bois avec des questions-réponses en relation avec le domaine spatial. Des panneaux vous indiqueront la direction du sentier à la gare des Pléiades. Quelles sont les conditions nécessaires à l'apparition et au développement de la vie sur une planète? Cette question pourtant très simple ne possède pas encore de réponse claire et fait régulièrement l'objet de grands débats au sein de la communauté scientifique. La plupart des astronomes pensent que la planète doit se trouver dans la "zone habitable" de l'étoile, c'est-à-dire dans la zone où l'eau peut être sous forme liquide. L'étoile en question doit également avoir une durée de vie suffisante pour permettre à la vie de se développer. Question: Laquelle de ces affirmations est correcte? (1) La zone habitable du Soleil se rapproche au fur et à mesure que celui-ci vieillit.

www.amateurmicroscopy.net...The World's Best Microscope I recently purchased a different trinocular head for my venerable old Nikon microscope. In the process of setting up the head I found a number of issues that I could not seem to get resolved. In frustration, I caught myself thinking, "Boy, if only I had a Zeiss (or Leitz, or Wild, or Olympus...) I wouldn't be having these problems!" Now, mind you, I am an amateur microscopist of very limited financial means. The "World's Best Microscope" is the one you can afford to buy and will use regularly. Be realistic about your needs, expectations, and financial capabilities. You have to learn to walk before you can run. Don't buy less than you need. Concentrate on what you can do with your current microscope, not on what you can't do with it.

I was hoping to get more usage and "testing" done before I posted these, but a few recent threads about LED lights have prompted me to post these now while people may be mulling over the possibilities. My usage is indoors, "tabletop", with access to line voltage (no need for batteries). I wanted a light that was considerably brighter than the Ikea, had adjustable intensity, and a very high CRI. The LED is a Bridgelux COB, "Decor Ultra Vero 10". ) has the heat-sink reach a temperature that feels about the same as the heat-sink temp on the Ikea). A big plus with this Bridgelux was that after some searching I found other needed components that were "plug-and-play" with this chip... heat sink, fast and simple Molex connector, and reflector holder and reflector. Here's what they look like and a few comments. Here's the heat-sink, made by Wakefield.
Talking Glossary of Genetic Terms Glossary Home | Text Version Designed to help learners at any level better understand genetic terms Guided by national science standards Explained by scientists at the NIH The National Human Genome Research Institute (NHGRI) created the Talking Glossary of Genetic Terms to help everyone understand the terms and concepts used in genetic research. In addition to definitions, specialists in the field of genetics share their descriptions of terms, and many terms include images, animation and links to related terms. Enter a search term or explore the list of terms by selecting a letter from the alphabet on the left and then select from the terms revealed. The Talking Glossary At the bottom of most pages in the Talking Glossary are links to help you get the most out of this glossary.
Skeletal System The Skeleton is the name given to the collection of bones that holds the rest of our body up. Our skeleton is very important to us. It does three major jobs. It protects our vital organs such as the brain, the heart and the lungs. When you were born, your skeleton had around 350 bones. Our bones don't simply work on their own.

From the 1903 Bulletin of the Johns Hopkins Hospital, volume XIV, pp. 318-319, article by Harvy Cushing: "From an anatomical standpoint, instances of cervical rib are not exceedingly uncommon, and indeed reports of this anomaly are to be found in very early medical literature. Sir Thomas Brown in his Pseudoxia Epidemica or Commentaries on Vulgar Eerors (Second Edition, London, 1650, p. 292) speaks of the heated discussion over the biblical story, which arose from the description by Colombus of a female skeleton which possessed a supernumerary rib. 'That a Man hath one Rib lesse than a Woman, is a common conceit derived from the history of Genesis, wherein it stands delivered, that Eve was framed out of a rib of Adam; whence 'tis concluded the sex of Man still wants that rib our Father lost in Eve.
