Menschen lassen Gletscher immer rascher schmelzen

Mit Hilfe einer Kombination von Klima- und Gletschermodellen haben Forscher um Ben Marzeion von der Universität Innsbruck eindeutig nachgewiesen, dass die Menschen für das weltweite Abschmelzen der Gletscher mitverantwortlich sind. In Science berichten die Forscher, dass von 1851 bis 2010 der vom Menschen verursachte Klimawandel rund ein Viertel zur Gletscherschmelze beitrug.

Schmelzende Gletscher lassen den Meeresspiegel steigen, verändern die saisonale Verfügbarkeit von Trinkwasser und können Auslöser von Naturkatastrophen sein. Sie stehen heute symbolisch für den vom Menschen verursachten Klimawandel. Allerdings reagieren Gletscher nur sehr langsam auf klimatische Veränderungen. „Typischerweise dauert es Jahrzehnte oder Jahrhunderte bis ein Gletscher sich an das Klima angepasst hat“, sagt Klimaforscher Ben Marzeion vom Institut für Meteorologie und Geophysik der Universität Innsbruck. Ihr Abschmelzen hat bereits mit dem Ende der kleinen Eiszeit Mitte des 19. Jahrhunderts begonnen. Natürliche Ursachen wie die veränderte Sonneneinstrahlung sind dafür genauso verantwortlich wie die vom Menschen ausgelösten Veränderungen. Bisher war allerdings unklar, wie viel die Menschen tatsächlich zum Verschwinden der Gletscher beitragen. (more…)

Interview with Baban Mohamed: ‘Code-switching’, a research project on Kurdish community in Austria

Baban Mohamed received his Master’s degree in English and American Studies (General/Applied Linguistics) from the University of Salzburg in Austria. He has B.A. degree in English Language and Literature from the University of Sulaimania (the Kurdistan Region of Iraq). Since 2005 Baban is living and studying in the beautiful Mozart’s City of Music, Salzburg. His research interests cover the areas of bilingual/ bicultural acquisition, child code-switching and sociolinguistics.

Q. Very recently you published research work titled: ‘Code-switching: A Case Study of Kurdish-German Pre-school Bilingual Children’ as part of European University Studies. Before going deep into your research, my first question to you: What is Bilingualism’?

Baban Mohamed: The book is a sociolinguistic research within the field of child bilingualism about the language and culture development of immigrant pre-school children, the case study of Kurdish community in Austria. The book addresses accounts of how children develop the functions and roles of different languages and how they manage to keep the language systems apart or switch from one to the other – not arbitrarily or due to a lack of competence as sometimes has been suggested but purposefully and with functions in mind.  (more…)

‘Life as Research Scientist’: Romain Fleury, Engineer

Due to deep passion for physics, Romain Fleury, after completion of his engineering diploma in France, joined the research group of Prof. Andrea Alù at the University of Texas at Austin, where he is currently pursuing a Ph.D degree. His research focuses on metamaterials, a new branch of science and technology that is making its way to maturity. To know and understand details about it and further more, let’s join our latest round of Q&A with the young and aspiring scientist – Mr. Romain Fleury:

Q. Let us start with your research topic. What is your research area? Will you please tell us a bit more on this? What did you find?

Romain Fleury: I am involved in cross-disciplinary research in the general area of wave physics and engineering. This includes electromagnetic and acoustic waves, but also other types of waves such as matter waves (the probability amplitude wave associated with a quantum particle). To be more specific, my current research mainly focuses on metamaterials, which are artificial materials that are structured and engineered to interact with waves in anomalous ways, and enable exotic physical phenomena that cannot be obtained with natural materials. For example, unlike naturally occurring materials, the refractive index of some metamaterials can take very extreme values, like zero, extremely large, or even negative. Of course, metamaterials are made of natural materials, with common properties, but it is the way we mix and structure these natural building blocks that give metamaterials their new, superior properties. Metamaterials have spectacular applications, like invisibility. Part of my research is focused on studying the potentials of metamaterials for cloaking applications. (more…)

Microsoft releases global survey revealing widespread belief in developing and developed nations that personal technology is transforming lives for the better

Findings: technology strongly impacts business innovation including starting new businesses; developing countries believe strongly that personal tech spurs job opportunities and eliminates harmful economic gaps, boosts education.

DAVOS, Switzerland — Jan. 24, 2014 — A new global survey of Internet users conducted by Microsoft Corp. reveals distinct regional findings and differing viewpoints between the developed and developing world. However, overwhelmingly the more than 10,000 people surveyed from 10 nations said they embrace personal technology, particularly in emerging markets, and see it as the foundation of innovation and economic empowerment.

A shot in the dark: Detector at UW on the hunt for dark matter

Leslie Rosenberg and his colleagues are about to go hunting. Their quarry: A theorized-but-never-seen elementary particle called an axion.

The search will be conducted with a recently retooled, extremely sensitive detector that is currently in a testing and shakeout phase at the University of Washington’s Center for Experimental Nuclear Physics and Astrophysics. (more…)

UCLA physicists played prominent role in Nobel Prize-winning Higgs boson research

Two large collaborations of scientists working at the Large Hadron Collider in Switzerland made worldwide news in July 2012 when they announced independent observations of the elusive Higgs boson particle — a discovery hailed as one of the greatest scientific accomplishments of recent decades.

This so-called “God particle” was first postulated some 50 years ago as a crucial element of the modern theory of the forces of nature — it is, physicists say, what gives everything in the universe mass — and it had been the subject of worldwide searches ever since. (more…)

Higgs Boson Discussion Launches UChicago Discovery Series

The long-sought Higgs boson—the particle that endows all elementary particles in the universe with mass—was elusive no longer when scientists at the CERN physics laboratory in Switzerland, discovered it last summer.

The July 4, 2012 announcement of the discovery appealed to both the general public and the media: Fifty-five media organizations and more than one billion television viewers made it an event that couldn’t be missed. Time even dubbed the Higgs boson “Particle of the Year.” (more…)
