Researchers have clarified one of the mysteries of 2018 in the field of extragalactic astrophysics: the supposed existence of a galaxy without dark matter. Galaxies with no dark matter are impossible to understand in the framework of the current theory of galaxy formation, because the role of dark matter is fundamental in causing the collapse of the gas to form stars. In 2018, a study published in Nature magazine announced the discovery of a galaxy that lacked dark matter, which made a strong impact, and occupied the covers of popular scientific magazines.

Possible relationship between gut microbial health and sleep disorder. Small intestine bacterial overgrowth (SIBO) may be more prevalent among patients with restless legs syndrome (RLS), according to preliminary findings from a small, new study.

Results show that SIBO was found in all seven participants who have RLS. In contrast, the prevalence of SIBO in the general population is estimated to be no more than 15%.

“We’ve observed extremely high rates of small intestinal bacterial overgrowth in the RLS group,” said lead author Daniel Jin Blum, Ph.D., D.B.S.M...

New research looks at the possibility of moons outside our solar system causing gaps in the rings of planet J1407b. Moons orbiting planets outside our solar system could offer another clue about the pool of worlds that may be home to extra-terrestrial life, according to an astrophysicist at the University of Lincoln.

Exoplanets are planets outside our solar system and up to this point nearly 4,000 have been discovered. Only a small proportion of these are likely to be able to sustain life, existing in what is known as the habitable zone. But some planets, especially large gas giants, may harbour moons which contain liquid water.

Dr Sutton said: “These moons can be internally heated by the gra...
