Kiesgeprägte Ströme – unser Gewässertyp des Jahres 2016

Donau, Rhein und Co. allerdings nur zu drei Prozent in gutem Zustand

Pünktlich zum Internationalen Weltwassertag am 22. März kürt das Umweltbundesamt (UBA) den Gewässertyp des Jahres 2016: die großen, von Kies geprägten Ströme. Vertreter sind beispielsweise Donau, Rhein und Elbe. Wie kaum ein anderer Gewässertyp wurden die Gewässerlandschaften der großen Flüsse seit Jahrhunderten erschlossen und kultiviert. Ihr Zustand ist daher nur selten als gut zu bezeichnen. In den großen, von Kies geprägten Strömen erreicht nur ein einziger Abschnitt der Donau derzeit das Ziel des Gewässerschutzes – den guten ökologischen Zustand. Der gute Zustand ist jedoch das Ziel, das sich der Gewässerschutz bis 2027 auferlegt hat. (more…)

Hot Spots, Cold Spots: When Temperature Goes Quantum

A UA-led collaboration of physicists and chemists has discovered that temperature behaves in strange and unexpected ways in graphene, a material that has scientists sizzling with excitement about its potential for new technological devices ranging from computing to medicine. (more…)

Ocean on Saturn Moon Could be as Salty as the Dead Sea

Scientists analyzing data from NASA’s Cassini mission have firm evidence the ocean inside Saturn’s largest moon, Titan, might be as salty as Earth’s Dead Sea.

The new results come from a study of gravity and topography data collected during Cassini’s repeated flybys of Titan during the past 10 years. Using the Cassini data, researchers presented a model structure for Titan, resulting in an improved understanding of the structure of the moon’s outer ice shell. The findings are published in this week’s edition of the journal Icarus. (more…)

Mapping Volcanic Heat on Io

A new study finds that the pattern of heat coming from volcanoes on Io’s surface disposes of the generally-accepted model of internal heating. The heat pouring out of Io’s hundreds of erupting volcanoes indicates a complex, multi-layer source. These results come from data collected by NASA spacecraft and ground-based telescopes and appear in the June issue of the journal Icarus.

A map of hot spots, classified by the amount of heat being emitted, shows the global distribution and wide range of volcanic activity on Io. Most of Io’s eruptions dwarf their contemporaries on Earth. (more…)

Where the Germs Are: Office Kitchens, Break Rooms

A study aided by UA microbiologist Charles Gerba finds that office kitchens and break rooms are frequent hot spots for bacteria.

If you thought the restroom was the epicenter of workplace germs, you don’t want to know about office break rooms and kitchens.

The place where U.S. workers eat and prepare their lunches topped the list of office germ hot spots, with the sink and microwave door handles found to be the dirtiest surfaces touched by office workers on a daily basis. (more…)

High Population Density is Greatest Risk Factor For Water-Linked Diseases

COLUMBUS, Ohio – Water-associated infectious disease outbreaks are more likely to occur in areas where a region’s population density is growing, according to a new global analysis of economic and environmental conditions that influence the risk for these outbreaks.

Ohio State University scientists constructed a massive database containing information about 1,428 water-associated disease outbreaks that were reported between 1991 and 2008 around the world. By combining outbreak records with data on a variety of socio-environmental factors known about the affected regions, the researchers developed a model that can be used to predict risks for water-associated disease outbreaks anywhere in the world.

Five U.S. Urban Counties Lead ‘Terror Hot Spots’ List, but Rural Areas Not Exempt: Research

*N.Y., L.A., Miami, San Francisco, D.C. Top List; Maricopa, Ariz. Rising*

COLLEGE PARK, Md. – Nearly a third of all terrorist attacks from 1970 to 2008 occurred in just five metropolitan U.S. counties, but events continue to occur in rural areas, spurred on by domestic actors, according to a report published today by researchers in the National Consortium for the Study of Terrorism and Responses to Terrorism (START), a Department of Homeland Security Science and Technology Center of Excellence based at the University of Maryland.

The research was conducted at Maryland and the University of Massachusetts-Boston. (more…)
