Book focuses on race relations between Native Americans, African Americans
It’s a rosy picture, to think of Native Americans and African Americans embracing one another over the course of our country’s history.
But that rosy picture has a dark side, one tainted by tense race relations little discussed in the academic literature, pop culture and history textbooks, according to the University of Delaware’s Arica Coleman. (more…)
For the first time, scientists have used new technology which analyses the whole genome to find the cause of a genetic disease in what was previously referred to as “junk DNA”.
Pancreatic agenesis results in babies being born without a pancreas, leaving them with a lifetime of diabetes and problems digesting food.
In a breakthrough for genetic research, teams led by the University of Exeter Medical School and Imperial College London found that the condition is most commonly caused by mutations in a newly identified gene regulatory element in a remote part of the genome, which can now be explored thanks to advances in genetic sequencing.

NABU fordert Vorreiterrolle Deutschlands bei UN-Klimakonferenz in Warschau
Auf der UN-Klimakonferenz debattiereren derzeit Vertreter von 195 Staaten und NGO’s über notwendige Maßnahmen beim Klimaschutz. Mit dabei ist auch Ulf Sieberg, Energieexperte beim NABU. Im Interview liefert er seine Eindrücke vor Beginn der entscheidenden Verhandlungsphase in Warschau.
Die UN-Klimakonferenz tagt zurzeit in Warschau. Was genau passiert dort?
Der Klimawandel macht vor Ländergrenzen nicht halt. Um ihm entgegenzuwirken sind internationale Abkommen wie die 1992 in New York beschlossene Klimarahmenkonvention notwendig, welche das Ziel formulierte, die negativen Auswirkungen menschlichen Handelns auf das Klima zu reduzieren. Auf einer seither jährlich stattfindenden Klimakonferenz, der United Nations Framework Convention on Climate Change (UNFCCC), treffen die politischen Vertreter aus nahezu 200 Ländern der Welt als auch zahlreiche Nichtregierungs-Organisationen, um in unterschiedlichen Gremien einen Weltklimavertrag auszuhandeln.

– 15,000 bubbles are simulated using IBM BlueGene/Q “Sequoia” at 14.4 Petaflop of sustained performance, a 150-fold improvement over current state-of-the-art
– Destructive capabilities of collapsing bubbles are increasingly being studied in areas ranging from treating kidney stones and cancer to high pressure fuel injectors
– Research team named as a Finalist for the 2013 Gordon Bell Prize (more…)
A study in Nature Communications finds that an enzyme that edits RNA may loosen the genome’s control over invasive snippets of DNA that affect how genes are expressed. In fruit flies, that newly understood mechanism appears to contribute to differences among individuals such as eye color and life span.
PROVIDENCE, R.I. [Brown University] — The story of why we are all so different goes well beyond the endless mixing and matching of DNA through breeding. A new study in the journal Nature Communications, for instance, reports a new molecular mechanism of individual variation found in fruit flies that uses components operating in a wide variety of species, including humans.

Advances in cameras, new strategies for detection make it possible
COLUMBUS, Ohio — Astronomers at The Ohio State University have calculated the odds that, sometime during the next 50 years, a supernova occurring in our home galaxy will be visible from Earth.
The good news: they’ve calculated the odds to be nearly 100 percent that such a supernova would be visible to telescopes in the form of infrared radiation. (more…)
The first dynamic regulatory system that prevents the build-up of toxic metabolites in engineered microbes has been reported by a team of researchers with the U.S. Department of Energy (DOE)’s Joint BioEnergy Institute (JBEI). The JBEI researchers used their system to double the production in Escherichia coli (E. coli) of amorphadiene, a precursor to the premier antimalarial drug artemisinin.
Using genome-wide transcriptional analysis, the JBEI researchers identified native regions of DNA – called “promoters” – in E. coli that respond to toxic metabolites by promoting the expression of protective genes. They then developed a system based on these promoters for regulating artificial metabolic pathways engineered into the E.coli to enable the bacterium to produce amorphadiene. (more…)
WWF begrüßt starkes Zeichen der USA im Kampf gegen Elefantenwilderei
Im Kampf gegen die Elefantenwilderei in Afrika setzen die USA ein starkes Zeichen. Gestern Abend sind sechs Tonnen vom US-Zoll beschlagnahmter Elfenbeinprodukte vernichtet worden. Der WWF begrüßt diese Aktion gegen den illegalen Elfenbeinhandel aufgrund seiner symbolische Wirkung: „Die Wildereikrise in Afrika verschärft sich immer mehr. Etwa jede Viertelstunde wird ein Elefant für sein Elfenbein getötet. Nur wenn wir die Absatzmärkte schließen und die Nachfrage eindämmen, wird die Wilderei aufhören, “ sagte Volker Homes, Leiter Artenschutz beim WWF Deutschland. (more…)
