Astronomers witness the Birth of a very Distant Cluster of Galaxies from the Early Universe

This image shows several galaxies distributed over a black background. The galaxies have colours that range from blue, orange-red, yellow and white. In the centre of the image is a larger concentration of galaxies. Overlaid on the galaxies in the middle is a blue and semi-transparent region. It has a clumpy form with indistinct contours. There are smaller, dark blue regions around it.
Using the Atacama Large Millimeter/submillimeter Array (ALMA), of which ESO is a partner, astronomers have discovered a large reservoir of hot gas in the still-forming galaxy cluster around the Spiderweb galaxy — the most distant detection of such hot gas yet. Galaxy clusters are some of the largest objects known in the Universe and this result, published today in Nature, further reveals just how early these structures begin to form.

Researchers discover a way to Fight the Aging Process and Cancer Development

The DREAM protein complex prevents the repair of genome damage in human cells, in mice and in the nematode Caenorhabditis elegans, a team of researchers at the University of Cologne has discovered. They also successfully inhibited this complex for the first time using a pharmaceutical agent.

“When we suppress the so-called DREAM complex in body cells, various repair mechanisms kick in, making these cells extremely resilient towards all kinds of DNA damage,” said Professor Dr Björn Schumacher, Director of the Institute for Genome Stability in Aging and Disease at the University of Cologne...

How Cosmic Winds Transform Galactic Environments

Researchers model how elements move across star-forming regions. Much like how wind plays a key role in life on Earth by sweeping seeds, pollen and more from one place to another, galactic winds — high-powered streams of charged particles and gases — can change the chemical makeup of the host galaxies they form in, simply by blowing in a specific direction.

Using observations made by NASA’s Chandra X-ray Observatory, a new study details how these energetic winds, once released from the center of a galaxy, directly influence the temperature and metal distribution of the rest of the region.

“Galactic winds are a large part of galaxy evolution in general,” said Sebastian Lopez, lead author of the study and a graduate...
