Stock traders have long used specialized trackers to decide when to buy or sell a stock, or when the market is beginning to make a sudden swing. (more…)

A New Paradigm in Parachute Design

By Guest PostJune 18, 2017Scienceharold barnard, mars parachute design, michael barnhardt, NASA, parachute fabrics, sky crane system

X-ray studies showing the microscopic structure of spacecraft parachute fabrics can fill in key details about how they perform under extreme conditions

As skydivers well know, it’s a good idea to look before you leap—and to pack a trusty parachute, too. A weighty spacecraft zooming toward a planet’s surface at several miles per second will, after enduring a superhot atmospheric entry, also benefit from careful planning and a reliable parachute.

Auf der Suche nach Abweichungen von der Standardtheorie der Quantenmechanik testeten Physiker, ob die Quantenmechanik ein noch raffinierteres mathematisches Regelwerk benötigt. Dazu entwickelte ein Team von Forschern an der Universität Wien um Philip Walther ein neues Photonen-Experiment, in das sie ungewöhnliche, an der Universität California Berkeley hergestellte Meta-Materialien einbauten.

On 4 September 2010, a powerful 7.1 magnitude earthquake struck the South Island of New Zealand near Christchurch. The earthquake’s epicentre was 40 kilometres (25 mi) west of Christchurch, near the town of Darfield. Its known as the Canterbury earthquake or Darfield earthquake. The massive earthquake distorted railroad tracks that crossed the fault line near Rolleston.

Wasserqualität von Flüssen: Zusätzliche Reinigungsstufen in Kläranlagen lohnen sich

By Guest PostJune 9, 2017Sciencediclofenac, keime im wasserkreislauf, rita triebskorn, spurenstoffe in abwasser, wasserqualitaet von fluessen

Viele Keime und Spurenstoffe in Abwasser könnten kostengünstig ausgefiltert werden

Eine zusätzliche Reinigungsstufe in Kläranlagen könnte mit geringem Aufwand große Mengen an Schadstoffen aus dem Abwasser entfernen und die Wasserqualität von Flüssen deutlich verbessern. Zu diesem Ergebnis kommen Wissenschaftlerinnen und Wissenschaftler in einem von der Universität Tübingen koordinierten Forschungsprojekt. Sie haben im Auftrag des Bundesministeriums für Bildung und Forschung untersucht, wie effizient weitergehende Abwasserreinigung in Kläranlagen und Regenwasserbehandlungssystemen neuartige Verschmutzungen in Flüssen beseitigt.

Berkeley Lab and NASA collaborate in X-ray experiments to ensure safety, reliability of spacecraft systems

It takes rocket science to launch and fly spacecraft to faraway planets and moons, but a deep understanding of how materials perform under extreme conditions is also needed to enter and land on planets with atmospheres. (more…)
