Hadley Cells: A Crucial Cog in Earth’s Climate Machine

Hadley Cells: A Crucial Cog in Earth’s Climate Machine

Atmospheric circulation is an important component of Earth’s climate. It transports heat and water across the globe, thereby ensuring that climate remains relatively constant throughout the years. Even small disruptions to this system could cause large, and possibly dangerous consequences. Why are rainforestes and deserts distributed in ordered arrays around the world? Hadley cells.

Fool Proof 2: Another Dose of Foolish Science

Another year has passed, and another April Fools’ Day has come. Here in the Bruce Museum Science Department, we’d much rather educate than mislead, and this particular holiday gives us a chance to delve into some of the more foolish sides of science. Last year, I chose some of the top scientific conspiracy theories to explore in honor of the occasion. This year I’m doing the same, talking about some of the most interesting, amusing, and intriguing scientific conspiracy theories, and why we shouldn’t take them too seriously.

Life and Death in the Land of Eternal Midnight

Life and Death in the Land of Eternal Midnight

On both land and sea, the sun is the primary source of energy in most ecosystems. Plants or algae use sunlight to create food through photosynthesis. Animals eat the plants and algae, and then get eaten themselves by predators higher up the food chain. Without the sun providing a base amount of energy input, most ecosystems would swiftly collapse. Even so, there are some animals that live beyond reach of the sun’s rays.

How can life exist in the deep ocean without getting energy from the sun?

A History of Human Evolution Written in Our Bodies

A History of Human Evolution Written in Our Bodies

A vestigial structure is a body part or organ that was useful in an ancestor, but is diminished in size, complexity, or utility in their descendant. Many animals have vestigial structures, like the small spurs on pythons that once were legs. Humans have vestigial structures too, and they give us a tantalizing glimpse into our evolutionary history.
