Belching black hole proves a biggie: First known ‘middleweight’ black hole

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.

Human brain houses diverse populations of neurons, new research shows

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.
