Science correspondent Laurie Winkless joins Kathryn to talk about why severe air turbulence is getting worse.
A new study from the University of Reading took 40 years of observations from aircraft and satellite and found the likelihood of hitting clear-air turbulence has increased. So where are you most likely to encounter it?
She'll also talk about a new study which has found squeezing molecules together could help reduce chemical waste and how robots in sewers are helping to combat dengue-carrying mosquitoes.
Laurie Winkless is a physicist and science writer.
