You are what you eat

by naturallyspeakingpodcast in Naturally Speaking Podcast

Ecologists have long tried to understand what animals get up to when they’re not being observed. GPS technologies have enabled unprecedented remote-tracking, but some behaviours – such as diet – are a little more tricky to track. In this post James Grecian (@JamesGrecian), a marine ecologist at the Institute, discusses a technique he uses to track the diet of marine seabirds across some of the world’s […]

The Chemistry of Christmas

by Melissa Chernick in Science Storiented

What are the sights, the sounds, the smells, and the textures that you associate with Christmas? Perhaps it is Christmas trees with their lovely green shape, color and wonderful pine smell. Maybe it’s the smells of cooking, the savory smells of turkey or the sweet smell of warm cookies. Or what about all of the cozy feelings you get with big sweaters or a roaring fire? Did you know that there is a lot of chemistry that goes into all of the senses we associate with this holiday?I was browsing t........ Read more »
