Researchers using the Atacama Large Millimeter/submillimeter Array (ALMA) discovered a titanic galactic wind driven by a supermassive black hole 13.1 billion years ago. This is the earliest example yet observed of such a wind to date and is a telltale sign that huge black holes have a profound effect on the growth of galaxies from the very early history of the universe.

At the center of many large galaxies hides a supermassive black hole that is millions to billions of times more mas...

Researchers discover an unexpected link between DNA winding and metabolism in the gut to ameliorate aging. Our genetic material is stored in our cells in a specific way to make the meter-long DNA molecule fit into the tiny cell nucleus of each body cell...

Using a new 3D printing process, University of Nottingham researchers have discovered how to tailor-make artificial body parts and other medical devices with built-in functionality that offers better shape and durability, while cutting the risk of bacterial infection at the same time.

Study lead, Dr Yinfeng He, from the Centre for Additive Manufacturing, said: “Most mass-produced medical devices fail to completely meet the unique and complex needs of their users. Similarly, single-material 3D printing methods have design limitations that cannot produce a bespoke device with multiple biological or mechanical functions.

“But for the first time, using ...

Astronomers describe a ‘changing-look’ blazar — a powerful active galactic nucleus powered by supermassive blackhole at the center of a galaxy. A University of Oklahoma doctoral student, graduate and undergraduate research assistants, and an associate professor in the Homer L. Dodge Department of Physics and Astronomy in the University of Oklahoma College of Arts and Sciences are lead authors on a paper describing a “changing-look” blazar – a powerful active galactic nucleus powered by supermassive blackhole at the center of a galaxy...
