Puzzling ‘cold quasar’ forming new stars in spite of active galactic nucleus — ScienceDaily

Researchers from the University of Kansas have described a galaxy more than 5.25 billion light years away undergoing a rarely seen stage in its galactic life cycle. Their findings recently were published in the Astrophysical Journal.

The galaxy, dubbed CQ 4479, shows characteristics that normally don’t coexist: an X-ray luminous active galactic nuclei (AGN) and a cold gas supply fueling high star formation rates.

“Massive galaxies, such as our own Milky Way, host a supermassive black hole at their hearts — these are black holes that grow by accreting interstellar gas onto themselves to become more massive,” said Kevin Cooke, lead author and postdoctoral researcher in KU’s Department of Physics & Astronomy. “The end of galactic growth is thought to happen when this gas accretion onto the black hole occurs in sufficient quantities that it produces a tremendous amount of energy. Then, all of that energy surrounding the black

Genes that give plant nucleus its shape discovered, also regulate copper tolerance — ScienceDaily

Researchers at the University of Tokyo have identified how the architecture of the cell nucleus can change gene activity in plants. This discovery reveals fundamental knowledge about genome regulation and points towards future methods for potentially manipulating the expression of many genes simultaneously.

The long strands of DNA and the protein machinery needed to turn gene expression on or off are contained, floating within the nuclei of cells. The nucleus is essentially a sack made of a flexible, double-membrane envelope that is supported by an inner, fine-mesh frame of proteins called the nuclear lamina.

“DNA does not drift aimlessly within the nucleus. We expect that there is nonrandom spatial positioning of genes around the nuclear lamina,” said Professor Sachihiro Matsunaga who led the research project from the University of Tokyo Graduate School of Frontier Sciences, recently published in Nature Communications.

Gene regulation is often studied at the one-dimensional level
