Researchers reveal an RNA modification influences thousands of genes
Over the past decade, research in the field of epigenetics has revealed that chemically modified bases are abundant components of the human genome and has forced us to abandon the notion we've had since high school genetics ...

Jarid2 may break the Polycomb silence
Historically, fly and human Polycomb proteins were considered textbook exemplars of transcriptional repressors, or proteins that silence the process by which DNA gives rise to new proteins. Now, work by a ...

Defect in transport system causes DNA chaos in red blood cells
Within all our cells lies two meters of DNA, highly ordered in a structure of less than 10 micro meters in diameter. Special proteins called histones act as small building bricks, organising our DNA in this structure. Preservation ...

Synthetic biology: German researchers develop novel kind of fluorescent protein
Since the 1990s a green fluorescent protein known as GFP has been used in research labs worldwide. Protein designers at Technische Universitaet Muenchen have now taken it a step further: They have managed to incorporate a ...

Marine bacteria cope with harsh mileu, learn to adapt
Marine bacteria live in a harsh mileu. They must constantly cope and adapt to changes in salinity, pH, temperature and other parameters. In her thesis, Barbara Weber, Umea University, studied how bacteria communicate with ...

How to count the messenger out: Mapping the structure of protonated water clusters
Water molecules are continuously forming short-lived networks called clusters. These can in turn bind positively charged protons, and such clusters can provide active functional groups in proteins. Using infrared spectroscopy, ...

For cancer cells, genetics alone is poor indicator for drug response (w/Video)
In certain respects, cells are less like machines and more like people. True, they have lots of components, but they also have lots of personality. For example, when specific groups of people are studied in ...
