Small and extremely resilient—the secrets of black fungi

Highly resistant to stresses, black fungi are real champions among microorganisms. With the support of the Austrian Science Fund FWF, a research team in Vienna discovered that the fungi owe their qualities to hitherto unknown ...

Barcodes to identify gene regulators

The same DNA is present in every cell of an organism, but only some genes are expressed in a given cell. These genes are activated by proteins called transcription factors, in response to various biological signals. Transcription ...

Researchers develop a small-molecule switch to activate proteins

From growing teeth, bones, and tissue in skin and organs to creating enzymes and hormones, proteins are one of the most diverse and important elements of living organisms. But those varied purposes, along with the interconnectivity ...

New imaging method reveals nanoscale details about DNA

Researchers have developed a new enhanced DNA imaging technique that can probe the structure of individual DNA strands at the nanoscale. Since DNA is at the root of many disease processes, the technique could help scientists ...

Physicists develop new software for the life sciences

Scientists from Heidelberg University have developed a novel mathematical model to explore cellular processes: with the corresponding software, they now are able to simulate how large collections of cells behave on given ...

Scientists publish the first RNA interactome of the human nucleus

Studying sequence and function of DNA has been in the focus of life sciences for decades, but now the interest of many researchers has turned to the RNA. Today, many scientists believe that RNA molecules, together with a ...

Cells get noisy in crowded environments

Bacteria are incredibly small, yet pack an enormous diversity of different molecules such as DNA, mRNA and proteins. Chemists from Radboud University Nijmegen, Eindhoven and Paris now show for the first time that random variations ...
