EZB-Entscheidung: Draghi gibt Banken Zucker – und droht mit der Peitsche - Konjunktur Soziale Netzwerke dauerhaft einschalten BratislavaDie Banken in der Euro-Zone können sich noch mindestens ein Jahr lang unbegrenzt Geld bei der Europäischen Zentralbank (EZB) leihen. Diese Regelung werde mindestens bis zum 9. Bei ihrer Sitzung in Bratislava senkte die Europäische Zentralbank ihren Schlüsselzins von 0,75 auf das Rekordtief von 0,5 Prozent. Billiges Geld: Schlechte Zeiten für Sparer Warum macht die EZB das Geld im Euroraum noch billiger? Die EZB könnte die Banken zu einer stärkeren Kreditvergabe animieren, indem sie künftig eine Art Strafgebühr zahlen müssen, wenn sie Geld bei der Zentralbank parken. Banken können Geld bei der EZB parken, wofür sie in normalen Zeiten Zinsen bekommen. Stimmen zum Zinsentscheid der EZB Marcel Fratzscher (Präsident des DIW-Instituts):„Man sollte sich nicht an die Hoffnung klammern, dass die EZB-Entscheidung die Finanzierungsbedingungen in den Krisenländern deutlich verbessern wird.

Field Guide to X-ray Astronomy :: Stellar Evolution Stellar Evolution The Milky Way Galaxy contains several hundred billion stars of all ages, sizes and masses. One of the central quests of astronomy is to understand how these star form, shine for billions of years, and eventually fade quietly into the dark as white dwarf, or go out with a bang as supernovas. Chandra and other X-ray telescopes focus on the high-energy action of this drama - sudden outbursts on the turbulent surfaces of stars, gale-force outflows of gas from hot, luminous stars, and awesome shock waves generated by supernova explosions. Overview of Stellar Evolution A Star is Born A star is born when a cloud of gas and dust collapses to the point where the material in the center of the clump is so dense and hot that the nuclear fusion of hydrogen nuclei into helium nuclei can occur. Hydrogen Burning Core (Main Sequence) Fusion of hydrogen into helium in the core of star can sustain a star such as the Sun for billions of years. Red Giants. Mass Matters.
PlanetInAction.com - The planet is your playground Around the Solar System - In Focus Robotic probes launched by NASA, the European Space Agency (ESA), and others are gathering information all across the solar system. We currently have spacecraft in orbit around the Sun, Mercury, Venus, Earth, Mars, and Saturn, and two operational rovers on Mars. Several others are on their way to smaller bodies, and a few are heading out of the solar system entirely. Although the Space Shuttle no longer flies, astronauts are still at work aboard the International Space Station, performing experiments and sending back amazing photos. With all these eyes in the sky, I'd like to take another opportunity to put together a recent photo album of our solar system -- a set of family portraits, of sorts -- as seen by our astronauts and mechanical emissaries.

Creating a Learning Environment for Young Children The following is an excerpt from Teaching Our Youngest. Introduction What do effective preschool teachers and child-care providers do? What does a classroom that can enhance learning look like? Effective preschool classrooms are places where children feel well cared for and safe. Young children need teachers who welcome all children to their classrooms, including children from various cultures, whose first language is not English and children who have disabilities. Effective preschool teachers and child care providers: Know when children can figure out new ideas and concepts on their own and when it is important to explain things to them step-by-step. A Classroom to Enhance Learning Ms. She uses cupboards, screens, and tables to divide her classroom into children's work areas. Most of the books on the bookcases come from the classroom library, but others are part of a revolving collection of books that Ms.
Qualtrics | Sophisticated Research Made Simple Life on Earth under threat from CO2 levels, say scientists - Climate Change - Environment Current CO2 emissions are currently tracking on the highest trajectory envisaged by climate scientists. That means if nothing is done to reduce emissions significantly over the coming decades, over half of common plants and one-third of the animals could see a serious decline, the study concluded. Scientists came to the assessment by estimating the current and future geographical ranges of nearly 50,000 widespread and common species to see how rising temperatures are likely to affect their territorial limits as defined by the sort of climate they are adapted to live in. Plants, amphibians such as frogs and toads, and reptiles such as lizards are the groups that are likely to suffer the most from a changing climate because of their relative vulnerability to rising temperatures and inability to move rapidly from one territory to another, the study found.

Beyond 2012: Why the World Didn't End Beyond 2012: Why the World Didn't End If you're reading this story, it means the world didn't end on Dec. 21, 2012. Despite reports of an ancient Maya prophecy, a mysterious planet on a collision course with Earth, or a reverse in Earth's rotation, we're still here. The Mayan connection "was a misconception from the very beginning," says Dr. John Carlson, director of the Center for Archaeoastronomy. Video: Why The World Didn't End Yesterday For years leading up to the supposed apocalypse, NASA scientists worked to dispel the myths and answer questions on a host of 2012 topics: Question (Q): Are there any threats to the Earth in 2012? Answer (A):The world will not end in 2012. Q: What is the origin of the prediction that the world will end in 2012? A: The story started with claims that Nibiru, a supposed planet discovered by the Sumerians, is headed toward Earth. Q: Does the Mayan calendar end in December 2012? Video: NASA Scientist David Morrison Debunks the Myths A: Absolutely not.
50 Years of Incredible Space Images From the European Southern Observatory | Wired Science This week marks the 50th anniversary of one of the world’s leading astronomical institutions, the European Southern Observatory. In honor of ESO’s birthday, we take a look at some of its most stunning shots of the night sky, amazing objects in space, and the organization's beautiful telescope facilities. ESO started when astronomers from five European countries – Belgium, France, Germany, the Netherlands, and Sweden – came together on Oct. 5, 1962 to build a telescope in the Southern Hemisphere. Having a large telescope south of the equator gave these member states access to unprecedented clear skies and celestial objects that simply can’t be seen from the Northern Hemisphere, such as the Magellanic Clouds. Over the decades, many more countries have joined, including Denmark, Switzerland, Italy, Portugal, the United Kingdom, Finland, Spain, the Czech Republic, Austria, and, in 2010, Brazil, which became the first non-European state to join.
