And in the beginning was histone 1

A zygote is the first cell of a new individual that comes about as the result of the fusion of an ovule with a spermatozoid. The DNA of the zygote holds all the information required to generate an adult organism. However, ...

Largest, most accurate list of RNA editing sites

A research team centered at Brown University has compiled the largest and most stringently validated list of RNA editing sites in the fruit fly Drosophila melanogaster, a stalwart of biological research. Their research, which ...

How young genes gain a toehold on becoming indispensable

Fred Hutchinson Cancer Research Center scientists have, for the first time, mapped a young gene's short, dramatic evolutionary journey to becoming essential, or indispensable. In a study published online June 6 in Science, ...

Study reveals consequences of a lifetime of sexual competition

Males that spend all their time reacting to their rivals die earlier and are less able to mate later in life according to new research from the University of East Anglia. The research is the first study to quantify the consequences ...

A surprising new function for small RNAs in evolution

An international research team in including Christian Schlötterer and Alistair McGregor of the Vetmeduni Vienna has discovered a completely new mechanism by which evolution can change the appearance of an organism. The ...

Viable and fertile fruit flies in the absence of histone H3.3

Histones—proteins that package DNA—affect cell function differently than previously assumed: the cell doesn't need the histone H3.3 to read genes. Molecular biologists from the University of Zurich demonstrate that fruit ...

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 team of researchers ...

Fruit flies watch the sky to stay on course

Insects, equipped with complex compound eyes, can maintain a constant heading in their travels, some of them for thousands of miles. New research demonstrates that fruit flies keep their bearings by using the polarization ...
