Chemistry World Podcast

Donna Blackmond discusses why biological molecules favour a single handedness and how that asymmetry might have emerged. The homochirality discussion begins at 6:18. The episode also covers antiparasitic medicines recognised by the 2015 medicine Nobel prize, blood-based estimates of time since death, Matt Gunther’s interview with chemistry laureate Tomas Lindahl about DNA repair, polymer additives designed to reduce aviation-fuel fires, and carbon quantum dots produced from urine.
