Data recorded by NASA’s Chandra X-ray Observatory of a neutron star as it passed through a dense patch of stellar wind emanating from its massive companion star provide valuable insight about the structure and composition of stellar winds and about the environment of the neutron star itself...

Patients undergoing long-term treatment with steroids may suffer from metabolic side effects. Researchers at the Helmholtz Zentrum München and the Ludwig Maximilians University of Munich (LMU), partners in the German Center for Diabetes Research (DZD), have now pinpointed a mechanism that leads to so-called steroid diabetes. Their findings have been published in Nature Communications.

“Glucocorticoids such as cortisone have been used to treat inflammatory diseases such as asthma or rheumatism for many decades, and they are the most commonly prescribed anti-inflammatory drugs,” explains Prof...

New form of graphene oxide is fun to play with – and solves manufacturing challenges. A Northwestern University team is reshaping the world of graphene – literally. The team has turned graphene oxide (GO) into a soft, moldable and kneadable play dough that can be shaped and reshaped into free-standing, three-dimensional structures.

Called “GO dough,” the product might be fun to play with it, but it’s more than a toy. The malleable material solves several long-standing – and sometimes explosive – problems in the graphene manufacturing industry.

“Currently graphene oxide is stored as dry solids or powders, which are prone to co...

Interplay of twisting magnetic field, ‘negative-energy’ particles. How do black holes purge energy locked up in their rotation, jetting near-light-speed plasmas into space to opposite sides in one of the most powerful displays in the universe? These jets can extend outward for millions of light years.

New simulations led by researchers working at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley have combined decades-old theories to provide new insight ...
