Astronomers have found the first known ‘middleweight’ black hole. Before it was found, astronomers had good evidence for only supermassive black holes — ones a million to a billion times the mass of the Sun — and ‘stellar mass’ ones, three to thirty times the mass of the Sun.
Billions of years ago in the heart of a distant galaxy, a monster black hole shredded a passing star and emitted X-rays. Now astronomers are using X-ray echoes to study a newly awakened black hole for the first time.
Utilizing the Atacama Large Millimeter Array, one of the most powerful telescopes in the world, researchers have peered into the feeding habits of a supermassive black hole.
A team of researchers has developed the first scalable method to identify different subtypes of neurons in the human brain. The research lays the groundwork for ‘mapping’ the gene activity in the human brain and could help provide a better understanding of brain functions and disorders, including Alzheimer’s, Parkinson’s, schizophrenia and depression.
