In a case study of dams on the upper Missouri River, USGS researchers have demonstrated that an upstream dam is still a major control of river dynamics where the backwater effects of a downstream reservoir begin. In light of this finding, the conventional understanding of how a dam can influence a river may have to be adjusted to account for the fact that effects of river dams can interact with one another.

Die Aerologie als wichtiges Teilgebiet der Meteorologie beschäftigt
sich mit dem Zustand der Atmosphäre bis in große Höhen.
Erst durch die Kenntnis der Temperatur, der Feuchte und des Druckes
der Luft bis in Höhen um 12 km ist es möglich die großräumigen
Strömungsverhältnisse und zum Beispiel die Vorgänge der
Wolkenbildung, somit “das Wetter”, zu verstehen und in weiterer Folge
vorherzusagen. (more…)
In the late 1990s, the University of Washington created what was arguably the world’s first graduate program in astrobiology, aimed at preparing scientists to hunt for life away from Earth. In 2001, David Catling became one of the first people brought to the UW specifically to teach astrobiology.
Catling, a UW professor of Earth and space sciences, is the author of Astrobiology: A Very Short Introduction, the 370th offering in the Oxford University Press series of “very short introduction” books by experts in various fields. Catling was commissioned by editors to write the book, which was published in the United States on Jan. 1. Following are his answers to some questions about the book and astrobiology. (more…)

Recycling kennt jeder: Müll wird wiederverwertet. Um knappe Ressoucen zu schonen, erobert diese Idee nun auch die Modebranche. Aus gebrauchten oder überschüssigen Materialien entstehen hochwertige Einzelstücke und einen klingenden Namen hat der neue Trend auch bekommen: Upcycling.
Ob Lederretouren aus der Sofaproduktion, ausgediente Feuerwehrschläuche, alte Armeedecken oder schlicht und einfach Reste aus der Textilproduktion: Upcycling hat den entscheidenden Vorteil, dass Abfallprodukte oder nutzlose Stoffe in hochwertigere Produkte umgewandelt werden. Im Gegensatz zum normalen Recycling ist diese Form des Recyclings also eine echte Aufwertung. Das reduziert die Neuproduktion von Rohmaterialien und verringert damit Energieverbrauch, Luft- und Wasserverschmutzung sowie Treibhausgasemissionen. (more…)
Berkeley Lab Researchers Make a Powerful New Microscale Torsional Muscle/Motor from Vanadium Dioxide
Vanadium dioxide is poised to join the pantheon of superstars in the materials world. Already prized for its extraordinary ability to change size, shape and physical identity, vanadium dioxide can now add muscle power to its attributes. A team of researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) has demonstrated a micro-sized robotic torsional muscle/motor made from vanadium dioxide that for its size is a thousand times more powerful than a human muscle, able to catapult objects 50 times heavier than itself over a distance five times its length within 60 milliseconds – faster than the blink of an eye.

Mating and meiosis – the specialized cell division that reduces the number of chromosomes in a cell – are related, but in most yeasts they are regulated separately. Not so in Candida lusitaniae, where the two programs work in unison, according to a new study in Nature. Comparison with other species suggests that this fusion may support C. lusitaniae’s “haploid lifestyle” of maintaining only one set of chromosomes in each cell. (more…)
