00:46 Modifying a fungal drug to make it less toxic

Amphotericin B is a drug used to treat life-threatening fungal infections. But while it is effective against many fungal species, it is also extremely toxic to kidneys, meaning it is mostly used as a drug of last-resort. This week, a team has unpicked the mechanism behind the drug’s toxicity, allowing them to modify it and reduce side effects in human kidney cells. The researchers hope this new version of the drug could become a useful tool in fighting fungal diseases.

11:26 Phosphorus found at the edge of our Galaxy

Phosphorus is a vital element for life and for planet formation, but although abundant in the inner part of the Milky Way, it has been undetected in the outer regions of our Galaxy. Now, researchers have identified phosphorus-containing molecules huge distances from Earth, although exactly how this phosphorus was created is unclear. The team suspect that lower-mass stars are behind the phosphorus generation, and believe that the detection of the element could broaden the range of planets that may be habitable in our Galaxy.
