Mouth-Watering Flavor is Harder to Engineer Than We Hoped
Ana Gorelova writing for The Conversation
While companies producing plant-based meat substitutes are growing quickly, the future of cultured meat is still hazy.

Michaeleen Doucleff writing for NPR
About a hundred years ago, something devious started happening in our homes and offices, in our cars and at restaurants — and our backs have never been the same.

Malaria is among the world’s worst scourges. In 2016 the disease, which is caused by a parasite and transmitted by mosquitoes, infected 194 million people in Africa and caused 445,000 deaths.

Our brains have been primed from the early stages of evolution to respond to risk in order to keep us safe, but not all risky scenarios are as severe as a hungry wolf in the woods—and sometimes our minds flood us with apprehension when there is no risk at all.
