The southern part of the Indian Ocean is experiencing an increasing number of powerful, intense tropical cyclones. This places parts of southern Africa, particularly places like Madagascar, Mozambique and the islands of Reunion and Mauritius, in the eye of potentially devastating storms. Jennifer Fitchett explains this worrying new trend in the region's climate.
Fast Radio Bursts are extremely bright flashes of light with radio wavelengths. But that's about all scientists know for sure when it comes to this rare phenomenon. They don't know, for example, where the flashes originate or what causes them. Emma Platts and Amanda Weltman outline a new, collaborative project that's seeking answers.
