Science In Action - Deadly drought

East Africa has endured more than two years on continuous drought. The latest predictions suggest the drought is not likely to end any time soon. We look at why climate change and weather patterns in the Pacific and Indian oceans are largely to blame. Andrea Taschetto, chief investigator at the Centre on Climate Extremes at the University of New South Wales discusses the latest predictions

Drought has also been an issue in Europe, comparable with events nearly 500 years ago. Chantal Camenisch at the Institute of History at Bern University in Switzerland has been delving into European drought history and says despite the vast differences in living conditions there are many parallels with today.

CrowdScience - Can smells fill you up?

Imagine waking up to the smell of freshly baked bread. Doesn’t it make your mouth water? Now imagine the smell of a fish market on a warm day… still feeling hungry? CrowdScience listener Thanh from Vietnam is intrigued by the effects of smell on our appetite, and wants to know whether certain aromas can make us feel more full than others. Never averse to a food-based challenge, presenter Anand Jagatia takes us on a journey from the nose to the brain, where we find out what exactly happens when we get a whiff of various foods. He discovers how the digestive system prepares for a meal and the extent to which our stomach has a say in whether or not we want to eat, based on how appetizing the smells are around us. Anand also explores our cultural differences. In some parts of the world a stinky Limburger cheese is considered a delicacy, while in other places it could make people lose their lunch. We’ll find out why some of us get triggered in different ways than others.
