Ultraviolet Radiation from Massive Stars Shapes Planetary Systems

Up to a certain point, very luminous stars can have a positive effect on the formation of planets, but from that point on the radiation they emit can cause the material in protoplanetary discs to disperse.

To find out how planetary systems such as our Solar System form, an international research team including scientists from the University of Cologne studied a stellar nursery, the Orion Nebula, using the James Webb Space Telescope (JWST). By observing a protoplanetary disc named d203-506, they discovered the key role massive stars play in the formation of planetary systems that are less than a million years old...

Rheumatoid arthritis is a chronic inflammatory condition that can damage joints.

The new findings could lead to better treatments for rheumatoid arthritis, lupus and other inflammatory diseases – and may even help us slow aging.

Researchers have discovered how “leaky” mitochondria can drive harmful inflammation responsible for diseases such as lupus and rheumatoid arthritis. Scientists may be able to leverage the findings to develop better treatments for those diseases, improve our ability to fight off viruses and even slow aging.

The new discovery reveals how genetic material can escape from our cellular batteries, known as mitochondria, and prompt the body to launch a damaging immune response...

New insights on how galaxies are formed
Astronomers can use supercomputers to simulate the formation of galaxies from the Big Bang 13.8 billion years ago to the present day. But there are a number of sources of error. An international research team, led by researchers in Lund, has spent a hundred million computer hours over eight years trying to correct these.

The last decade has seen major advances in computer simulations that can realistically calculate how galaxies form...
