IBM Study: Hybrid Clouds Dominate — Enable Companies to Innovate, Exceed Expectations

ARMONK, N.Y. – 01 Sep 2016: Almost every company is using the cloud, but not for everything, finds a new IBM study. Seventy-eight percent of respondents say their cloud initiatives are coordinated or fully integrated, compared to just 34 percent in 2012. And, among high performing organizations, that number climbs to 83 percent. At the same time, nearly half of workloads — 45 percent — are expected to remain on-premises with dedicated servers.

Wie Staphylokokken Blutvergiftungen auslösen

Forscherteam identifiziert Lipopeptide als Ursache für schweren Krankheitsverlauf

Blutvergiftungen, verursacht durch Infektionen des bakteriellen Erregers Staphylococcus aureus, sind Ursache für viele tausend Todesfälle jährlich in Deutschland. Wie die Blutvergiftung bei solchen Infektionen ausgelöst wird und zum lebensbedrohlichen Multiorganversagen führt, war bislang weitgehend unverstanden. Auch sind die verfügbaren diagnostischen und therapeutischen Möglichkeiten derzeit sehr begrenzt. Forscher des Interfakultären Instituts für Mikrobiologie und Infektionsmedizin der Universität  Tübingen (IMIT) und des Deutschen Zentrums für Infektionsforschung (DZIF) um Dr. Dorothee Kretschmer, Dennis Hanzelmann und Professor Andreas Peschel haben nun eine der Ursachen für diesen schweren Krankheitsverlauf geklärt. Die Ergebnisse wurden im Fachjournal Nature Communications veröffentlicht. (more…)

New Measurement Technique Shows Link Between T-cells and Aging

AUSTIN, Texas — Researchers in the Cockrell School of Engineering at The University of Texas at Austin have discovered a correlation between aging and the effectiveness of T-cells, a type of immune cell programmed to fight or kill a threat. The researchers found that older people have T-cells that are less effective at fending off the hepatitis C virus (HCV). (more…)

Researchers Develop Faster, Precise Silica Coating Process for Quantum Dot Nanorods

Materials researchers at North Carolina State University have fine-tuned a technique that enables them to apply precisely controlled silica coatings to quantum dot nanorods in a day – up to 21 times faster than previous methods. In addition to saving time, the advance means the quantum dots are less likely to degrade, preserving their advantageous optical properties. (more…)

Die Klagen der Bauern im Callejón de Huaylas

In den peruanischen Anden hadern Kleinbauern mit dem Wetter, verändernde Niederschlagsmuster erschweren demnach den traditionellen Anbau. Gemeinsam mit Hamburger Sozialgeographen haben Innsbrucker Meteorologen diese subjektiven Beobachtungen mit Daten von Wetterstationen verglichen und kommen zu einem überraschenden Ergebnis. (more…)

Climate change alters the rules of sperm competition in the sea

The impact of climate change on global seawater conditions could change the rules of sperm competition for many important marine species, a pioneering new study has shown.

Researchers from the University of Exeter have shown that increasing ocean acidification, brought about by manmade carbon emissions, reduces sperm performance in a species of sea urchin, slowing down sperm in future ocean conditions. Interestingly, they found that different males were affected to different extents and that this could change the outcome when rival male ejaculates competed to fertilise a batch of eggs in the sea.
