Von Ölförderung bedrohtes UNESCO-Weltnaturerbe ist Schauplatz der 3D-Neuverfilmung
Die Legende kehrt zurück: Ab Donnerstag ist Superheld Tarzan in einer Neuverfilmung des Literaturklassikers zurück in den deutschen Kinos. Schauplatz des Dschungelabenteuers ist der Virunga-Nationalpark in Afrika. Der WWF warnt, dass die Zukunft der Region nicht nur im neuen 3D-Film bedroht sei. Im Film sucht ein skrupelloser Konzern nach einer geheimnisvollen Energiequelle im Regenwald. Die Realität ist weniger mysteriös aber nicht weniger bedrohlich: Im Virunga-Nationalpark, ein UNESCO-Weltnaturerbe in der Demokratischen Republik Kongo, will der britische Ölkonzern Soco Öl fördern.

Researchers had known for several decades that a certain chemical modification exists on messenger ribonucleic acid (mRNA), which is essential to the flow of genetic information. But only recently did experiments at the University of Chicago show that one major function of this modification governs the longevity and decay of RNA, a process critical to the development of healthy cells.
The chemical modification on mRNA in question is called N6-methyladenosine (m6A). A recent study by UChicago scientists reveals how the m6A modification on mRNA could affect the half-life of mRNA that in turn regulates cellular protein quantities. That discovery could provide fundamental insights into healthy functioning and disorders such as obesity, diabetes and infertility. (more…)
Study finds that human occupation of an area may not contribute to population decline of an endangered species
COLUMBIA, Mo. – Conservation of a protected or endangered species requires frequent monitoring and the dynamic techniques biologists utilize to ensure the survival of threatened animals. Often, scientists study biodiversity at all levels—from genes to entire ecosystems. Currently, researchers at the University of Missouri are employing genotyping to study movement patterns of African forest elephants in protected and unprotected regions of Gabon to better understand how human occupation of these areas might affect elephants on the African continent. Genotyping is helping conservation biologists determine the best course of action to ensure biodiversity and the preservation of various species in the U.S. and abroad. (more…)
As mice age, cells in tissues such as the liver and skeletal muscle lose control over rogue sequences of DNA called “retrotransposable elements,” according to new research in the journal Aging. The elements, which may undermine health, could proliferate in old mice and were also abundant in cancerous tissue. A low-calorie diet, however, restrained their advance.
PROVIDENCE, R.I. [Brown University] — The genomes of organisms from humans to corn are replete with “parasitic” strands of DNA that, when not suppressed, copy themselves and spread throughout the genome, potentially affecting health. Earlier this year Brown University researchers found that these “retrotransposable elements” (RTE’s) were increasingly able to break free of the genome’s control in cultures of human cells. Now in a new paper in the journal Aging, they show that RTEs were increasingly able to break free and copy themselves in the tissues of mice as the animals aged. In further experiments the biologists showed that this activity was readily apparent in cancerous tumors, but that it also could be reduced by restricting calories. (more…)
Researchers at Berkeley Lab’s Molecular Foundry Create First Soluble 2D Supramolecular Organic Frameworks
Supramolecular chemistry, aka chemistry beyond the molecule, in which molecules and molecular complexes are held together by non-covalent bonds, is just beginning to come into its own with the emergence of nanotechnology. Metal-organic frameworks (MOFs) are commanding much of the attention because of their appetite for greenhouse gases, but a new player has joined the field – supramolecular organic frameworks (SOFs). Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have unveiled the first two-dimensional SOFs that self-assemble in solution, an important breakthrough that holds implications for sensing and separation technologies, energy sciences, and, perhaps most importantly, biomimetics.

Researchers have sequenced the entire messenger RNA – the “genetic photocopies” – contained in the nucleus of a single cell, a long-anticipated step toward better cancer diagnostics and other medical applications.
Researchers have successfully isolated and sequenced the entire messenger RNA – the “genetic photocopies” – contained in the nucleus of a single brain cell. This research, published in the journal Proceedings of the National Academy of Sciences, will help researchers better understand how organs function in health and disease and provide another stepping stone toward personalized medicine.

IBM Predicts – in Five Years Everything will Learn
ARMONK, N.Y. – 17 Dec 2013: Today IBM unveiled the eighth annual “IBM 5 in 5“ (#ibm5in5) – a list of innovations that have the potential to change the way people work, live and interact during the next five years.
This year’s IBM 5 in 5explores the idea that everything will learn – driven by a new era of cognitive systems where machines will learn, reason and engage with us in a more natural and personalized way. These innovations are beginning to emerge enabled by cloud computing, big data analytics and learning technologiesall coming together, with the appropriate privacy and security considerations, for consumers, citizens, students and patients.
