Molecular 'tails' are secret ingredient for gene activation

It might seem as though humans have little in common with the lowly yeast cell. Humans have hair, skin, muscles, and bones, among other attributes. Yeast have, well, none of those things.

Histone H3-H4 tetramer found to be a copper reductase enzyme

A team of researchers at the University of California has found that the histone H3-H4 tetramer is a copper reductase enzyme. In their paper published in the journal Science, the group describes two experiments they carried ...

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 ...
