Schleppender Start für den Meeresschutz: UN-Treffen zur biologischen Vielfalt der Meere

Die erste Meereschutzkonferenz nach Rio+20 ist vorbei. Und das Schiff scheint Segel gesetzt zu haben, zwar langsam und gehemmt von eisigem Gegenwind, aber es ist in See gestochen. Zu diesem Ergebnis kommt das Bündnis „High Seas Alliance“ (HSA), an dem sich neben anderen Meeresschutzorganisationen auch Greenpeace beteiligt.

Im Zentrum der Verhandlungen stand ein neues Durchführungsabkommen im Sinne des Seerechtsübereinkommens der Vereinten Nationen (SRÜ). Dieses erhielt von vielen Staaten starke Unterstützung, darunter die G77 und China, die Europäische Union, Australien, Mexico und Neuseeland. Trotzdem verlangsamten die Blockadeversuche einer kleinen Minderheit dieses Prozess deutlich. (more…)

Self-Healing Solar Cells ‘Channel’ Natural Processes

To understand how solar cells heal themselves, look no further than the nearest tree leaf or the back of your hand.

The “branching” vascular channels that circulate life-sustaining nutrients throughout leaves and hands serve as the inspiration for solar cells that can restore themselves efficiently and inexpensively. (more…)

Hydraulic Fracturing Fluids Likely Harmed Threatened Kentucky Fish Species

Hydraulic fracturing fluids are believed to be the cause of the widespread death or distress of aquatic species in Kentucky’s Acorn Fork, after spilling from nearby natural gas well sites. These findings are the result of a joint study by the U.S. Geological Survey and the U.S. Fish and Wildlife Service.

The Acorn Fork, a small Appalachian creek, is habitat for the federally threatened Blackside dace, a small colorful minnow. The Acorn Fork is designated by Kentucky as an Outstanding State Resource Waters. (more…)

Muschel-Probleme ungelöst

WWF und Schutzstation Wattenmeer zum Start der Miesmuschelsaison: bestehende Praxis der Muschelfischerei in Schleswig Holstein ist unverträglich mit dem Nationalpark

Hamburg/Husum: Zum heutigen Auftakt der Fangsaison auf Miesmuscheln im schleswig-holsteinischen Wattenmeer üben die Umweltverbände Schutzstation Wattenmeer und WWF Kritik an der Muschelfischerei. Die natürlichen Miesmuschelbestände wurden auf einen Bruchteil reduziert, doch es dürfen weiter wilde Muscheln gefangen werden.

Dating violence impedes victims’ earnings

Dating violence in adolescence not only takes a physical and emotional toll on young women, it also leads to less education and lower earnings later in life, according to a first-of-its-kind study led by a Michigan State University researcher.

A young woman’s educational performance may be hindered by her partner’s actions, such as destroying books or homework or causing injuries that prevent her from going to school. (more…)

NASA’S Mars Curiosity Debuts Autonomous Navigation

PASADENA, Calif. – NASA’s Mars rover Curiosity has used autonomous navigation for the first time, a capability that lets the rover decide for itself how to drive safely on Mars.

This latest addition to Curiosity’s array of capabilities will help the rover cover the remaining ground en route to Mount Sharp, where geological layers hold information about environmental changes on ancient Mars. The capability uses software that engineers adapted to this larger and more complex vehicle from a similar capability used by NASA’s Mars Exploration Rover Opportunity, which is also currently active on Mars.
