00:47 Searching for dark matter in black holes
Researchers have been scanning the skies looking for black holes that formed at the very beginning of the Universe — one place where elusive and mysterious dark matter is thought to be located. If these black holes did contain dark matter, they would be especially massive and so researchers would be able to see the bending of light as they pass in front of stars. Such events would be rare, so to find them researchers trawled through a decades-long dataset. However, despite the large number of observations, the researchers didn’t find many examples of these events and none that were long enough to show signs of much dark matter. So, the hunt for enigmatic material goes on.

12:39 A simple, solution to tackle a deadly frog disease
A simple ‘sauna’ built of bricks and a supermarket-bought greenhouse, can help frogs rid themselves of a devastating fungal disease, new research has shown. Although options to prevent or treat infection are limited, the fungus that causes the disease chytridiomycosis has an achilles heel: it can’t survive at warm temperatures. A team in Australia used this knowledge to their advantage to develop saunas where frogs can warm themselves to clear an infection. Frogs who spent time in these hot environments were able to shake the fungus, and gained some immunity to subsequent infections. Although this research involved only one type of frog, it offers some hope in tackling a deadly disease that has driven multiple species to extinction.
