In a new study, scientists have mapped magnetic fields in galaxy clusters, revealing the impact of galactic mergers on magnetic-field structures and challenging previous assumptions about the efficiency of turbulent dynamo ...
European astronomers have conducted X-ray and optical observations of a transitional millisecond pulsar known as PSR J1023+0038. Results of the observational campaign, published November 23 on arXiv.org, yield important insights ...
Researchers have discovered a 380-million-year-old heart—the oldest ever found—alongside a separate fossilized stomach, intestine and liver in an ancient jawed fish, shedding new light on the evolution of our own bodies.
