The Power of Placebo: When Surgical Benefits Are All in the Mind

Thought is a powerful thing, powerful enough to have dramatic effects on our bodies and health. while it’s become commonplace to compare medicines to placebos, there are other medical treatments that usually go forward without this placebo testing. One field that rarely involves placebo testing is surgery. The idea of testing placebo surgeries may seem absurd, but given the risky nature of surgery, it is vitally important to make certain that surgical interventions do what they’re supposed to.

Nuisance to Nutrient: The Journey of Saharan dust from Africa to Amazonia

In the Sahara Desert, dust dominates. From Morocco to Sudan, strong winds continuously pick up dust from the desert floor and loft it into the air, decreasing air quality and exacerbating health problems for millions of people. However, this very same dust that is a detriment to the people of the Sahara is a crucial component to human and ecosystem health in Amazonia. Why and how does this happen? There's something very special lurking in that dust.

The Secret of the Exploding Glass Drops

The Secret of the Exploding Glass Drops

In the year 1660, Prince Rupert gave a very interesting gift to King Charles II: Five glass crystals, each with a bulbous head and a long tapering tail. Though they looked like unremarkable glass baubles and were made of no special material, it soon became obvious that their qualities were far from ordinary. Though the head of the drops were incredibly strong, the entire drop would explosively shatter after just one flick of the tail. For 400 years, Prince Rupert's drops were a mystery to scientists. Now, we finally understand the reason for their immense strength and fragility.

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.
