Epstein-Barr virus may affect health in more ways than known. A far-reaching study conducted by scientists at Cincinnati Children’s reports that the Epstein-Barr virus (EBV) – best known for causing mononucleosis – also increases the risks for some people of developing seven other major diseases. Those diseases are: systemic lupus erythematosus (SLE), multiple sclerosis (MS), rheumatoid arthritis (RA), juvenile idiopathic arthritis (JIA), inflammatory bowel disease (IBD), celiac disease, and type 1 diabetes. Combined, these seven diseases affect nearly 8 million people in the U.S.

Nearly a hundred years ago, Albert Einstein and Satyendra Nath Bose predicted that quantum mechanics can force a large number of particles to behave in concert as if they were only a single particle. The phenomenon is called Bose-Einstein condensation, and it took until 1995 to create the first such condensate of a gas of alkali atoms. Although Bose-Einstein condensation has been observed in several systems, the limits of the phenomenon need to be pushed further: to faster timescales, higher temperatures, and smaller sizes...

Can we tell black holes apart? Astrophysicists at Goethe University Frankfurt answer this question by computing images of feeding non-Einsteinian black holes: at present it is hard to tell them apart from standard black holes. Credit: Fromm/Younsi/Mizuno/Rezzolla (Frankfurt)

Astrophysicists have created and compared self-consistent and realistic images of the shadow of an accreting supermassive black hole. The goal was to test if Einsteinian black holes can be distinguished from those in alternative theories of gravity. One of the most fundamental predictions of Einstein’s theory of relativity is the existence of black holes...

This image was taken by Hubble’s Advanced Camera for Surveys and Wide Field Camera 3 as part of an observing program called RELICS (Reionization Lensing Cluster Survey). RELICS imaged 41 massive galaxy clusters with the aim of finding the brightest distant galaxies for the forthcoming James Webb Space Telescope to study. Credit: ESA/Hubble & NASA, RELICS

This NASA/ESA Hubble Space Telescope image shows a massive galaxy cluster glowing brightly in the darkness. Despite its beauty, this cluster bears the distinctly unpoetic name of PLCK G308.3-20.2. Galaxy clusters can contain thousands of galaxies all held together by the glue of gravity...
