Groundbreaking measurement reveals a black hole spinning at a quarter of the speed of light

A team of astronomers has managed to remotely calculate the speed of rotation of a supermassive black hole thanks to the object’s chance encounter with a star, which instantly destroyed it. How will time travel change Perry in Outer Range Season 2? All black holes have spin, which they develop through their interactions with other … Read more

Adhesive coatings can prevent scarring around medical implants

When medical devices such as pacemakers are implanted in the body, they usually cause an immune response that leads to the build-up of scar tissue around the implant. These scars, known as fibrosis, can interfere with the functioning of the devices and may require their removal. In a step forward that could prevent these types … Read more
