“Verwischte Zeiten” in der Quantenwelt

Uhren im Wechselspiel zwischen zwei fundamentalen Theorien moderner Physik

PhysikerInnen der Universität Wien und der Österreichischen Akademie der Wissenschaften um Časlav Brukner haben herausgefunden, dass die Genauigkeit der Zeitmessung fundamental eingeschränkt ist: Je genauer eine bestimmte Uhr arbeitet, umso mehr “verwischt” sie den Zeitfluss, den benachbarte Uhren messen. Infolgedessen ist die Zeit, die die Uhren anzeigen, nicht länger klar definiert. Diesen Nachweis erbrachten sie, indem sie Aspekte der Quantenmechanik und Einsteins Allgemeiner Relativitätstheorie kombinierten. Ihre Ergebnisse veröffentlichen die ForscherInnen in “PNAS”.

ANN ARBOR — A new study finds evidence that the last time Earth was as warm as it is today, cold freshwater from a melting Greenland ice sheet circulated in the Atlantic Ocean as far south as Bermuda, elevating sea levels and altering the ocean’s climate and ecosystems. (more…)

IBM Security Shares Tips To Stay Safe This Tax Season

54M Americans Wait Until Last Minute to File Taxes; Cybercriminals Poised to Exploit Tax Deadline to Cash in on Refunds

CAMBRIDGE, MA – 05 Apr 2017: IBM (NYSE: IBM) Security today released a new report taking a closer look at the techniques and motivations of cybercriminals targeting taxpayers in the United States.

Neue Hoffnung für die Saigas?

Saiga-Antilopen waren deutlich flexibler als gedacht.

Senckenberg-Wissenschaftler haben herausgefunden, dass die heute vom Aussterben bedrohte Saiga-Antilope in der Vergangenheit sehr viel flexibler bei der Wahl ihres Lebensraumes und ihrer Nahrung war als bisher vermutet wurde. Die Wissenschaftler verglichen anhand von Kohlenstoff- und Stickstoffisotopen im Kollagen der Antilopenknochen die Ernährung fossiler und heutiger Saigas. (more…)
