Honeybee researchers have discovered that the insects release a deadly odor that shortens the lifespan of their family members – usually their sisters.
Honeybee researchers have discovered that the insects release a deadly odor that shortens the lifespan of their family members – usually their sisters. "Previous research has shown that the presence of larvae in colonies reduces adult bees’ energy stores and shortens the honeybee lifespan. Scientists had also found that larvae release what is known as a "brood pheromone," which causes adults to consume more pollen to keep up with larval food demand. But little else was known about this rare chemical concoction found only in bees. When Amdam and colleagues fed synthetic pheromone-laced syrup to adult bees, they found something surprising: It depleted vital stores of a protein called vitellogenin from bees’ fat tissue and shortened their lives dramatically. The life expectancy of entire colonies dropped below 200 days, making it difficult for honeybees to last through winter."

Butter supply and life satisfaction are linked – but by causation or correlation?
- Haiti and other countries with low butter supply report low life satisfaction.
- The reverse is true for countries like Germany, which score high in both categories.
- As the graph below shows, a curious pattern emerges across the globe. But is it causation or correlation?
Advances in satellite imagery are shining a light.
- Today, there are 40.3 million slaves on the planet, more than the number of people living in Canada.
- Slavery can be hard to find, but it commonly occurs in several key industries like fishing and mining.
- Using satellite data, researchers and activists are using crowdsourcing and artificial intelligence to identify sites where slavery is taking place.
The catacombs of Paris. Secret graffiti beneath NYC. The hidden cities of Cappadocia. Writer and explorer Will Hunt is your philosophical tour guide to what lies beneath.
- "The surface of the earth is where we're rational . . . Part of us dreads the chaos, and part of us is always attracted to it."
- "There were these things hanging from the ceiling…long strands of bacteria called "snotsicles"… But at our feet was a natural stream that had been running through Brooklyn forever."
- "It's…about death. Undergoing a death. We're going into the other world and then retreating to the surface… changed in some way."
