Simulations show fundamental interactions inside the cell

Actin filaments have several important functions inside cells. For one, they support the cell membrane by binding to it. However, scientists did not know exactly how the actin interacts with the membrane lipids. Simulations ...

DNA from ancient packrat nests helps unpack Earth's past

New work shows how using next-generation DNA sequencing on ancient packrat middens—nests made out of plant material, fragments of insects, bones, fecal matter, and urine—could provide ecological snapshots of Earth's past. ...

Unique centromere type discovered in the European dodder

Whenever the European dodder, Cuscuta europaea, is under scientific scrutiny, it usually is due to its lack of chloroplasts and its concomitant parasitic lifestyle. However, since the beginning of this year its chromosomes ...

Expanding virophage diversity

Virophages are small viruses with double-stranded DNA genomes that co-infect eukaryotic cells along with giant viruses. Almost all known virophage genomes share only four genes in common: major and minor capsid proteins (MCP ...

How our single-celled relatives package their DNA

A group of single-celled organisms organises its DNA in a similar way to higher organisms such as plants, animals, and fungi. However, the way packaged DNA is read out differs between the two related groups, Bram Henneman ...

Cell biology: Compartments and complexity

Ludwig-Maximilians-Universitaet (LMU) biologists have taken a closer look at the subcellular distribution of proteins and metabolic intermediates in a model plant. The results of the study provide new insights into the dynamics ...
