A type of microRNA has been discovered that slows down the growth of prostate cancer cells, and could be used to improve treatments against the disease.

Bellbird..male or female?


A young bellbird (Anthornis melanura) that exhibits both male and female characteristics has been found in an eco-sanctuary in New Zealand. Although DNA testing from 2011 showed the bird as a female, its behaviour as well as physical charac

teristics (on one side it has the dark plumage of a male and on the other the yellowish feather pattern of a female) make it the first transgender bellbird. Researchers believe that this can be due to a hormonal imbalance.
