The findings reflect how post-publication commentary can help to identify errors or fraudulent results, say scientists. Previous research has shown that potentially problematic articles get

Initial analyses suggested if the dots were in fact supermassive black holes, they’d have to be nearly as massive as their host galaxies, varying between 10 and 100 percent of their total mass.

These beautiful predators glide effortlessly through the water, each slow, deliberate sweep of the powerful tail driving a body specialised for stealth, speed, and efficiency. From above, its dark back blends into the deep blue water, while from below its pale belly disappears into the
