A ‘monster’ star 2 million times brighter than the sun disappears without a trace
In 2019, scientists witnessed a massive star 2.5 million times brighter than the sun disappear without a trace. Now, in a new paper published today (June 30) in the journal Monthly Notices of the Royal Astronomical Society, a team of space detectives (see: astrophysicists) attempt to solve the case of the disappearing star by providing several possible explanations. Of these, one twist ending stands out: Perhaps, the researchers wrote, the massive star died and collapsed into a black hole without undergoing a supernova explosion first — a truly “unprecedented” act of stellar suicide.
Long-term exercise impacts genes involved in metabolic health
This suggests that even short training programs of 6–12 months are enough to positively influence the health of people suffering from metabolic disorders,” says last author Carl Johan Sundberg, professor at the Department of Physiology and Pharmacology, Karolinska Institutet. “The study identifies important ‘exercise-responsive’ genes that may play a role in metabolic diseases.
