Outstanding researchers present their work and share their opinions in Mapping Ignorance.
The brain plays an essential role in how people navigate the world by generating both thought and behavior. Despite being one of the most vital organs of life, it takes up only 2% of human body volume. How can something so small perform such complex tasks? Luckily, modern tools like brain mapping have allowed neuroscientists […]
We tend to think Antarctica is isolated and far away – biologically speaking, this is true. But the continent is busier than you probably imagine, with many national programs and tourist operators crisscrossing the globe to get there. And each vessel, each cargo item, and each person could be harbouring non-native species, hitchhiking their way […]
The American evolutionary psychologist David Buss contends in his 2005 book The Murderer Next Door: Why the Mind Is Designed to Kill that the evolutionary process humans acquired psychological adaptations to facilitate homicide. Natural selection, it is hypothesized, winnowed and perfected psychological mechanisms that solved certain problems by facilitating homicidal behavior. Of course, to solve […]

Yet, as we set our sights on embarking back to the moon, we will be bringing with us […]
The San Pedro River winds from rainforests in Guatemala through the Yucatan Peninsula in eastern Mexico. There, this peaceful river widens into a series of slow-flowing lakes. Along a remote 50-mile (80-kilometer) stretch, thousands of red mangroves – trees commonly found along tropical coastlines – line the river’s banks and gentle waterfalls. Unlike mangroves elsewhere […]
The reason that ibuprofen treats headaches and ice cream tastes sweet is that their chemical components fit perfectly into certain receptors in your body. The better a drug or flavor molecule fits with its matching receptor, the more effective the medicine or tastier the treat. But an interesting quirk of nature is that many […]
The eastern North American population of monarch butterflies are famous for their annual, multi-generational, round-trip migration from the oyamel fir forests of Central Mexico through the United States to Canada and back. Sadly, the population of monarch butterflies is declining, and the future of the monarch migratory phenomenon is uncertain. Scientists can study migrations by […]
