‘Bees are sentient’: inside the stunning brains of nature’s hardest workers

Fringe' research suggests the insects that are essential to agriculture have emotions, dreams and even PTSD, raising complex ethical questions

When Stephen Buchmann finds a wayward bee on a window inside his Tucson, Arizona, home, he goes to great lengths to capture and release it unharmed. Using a container, he carefully traps the bee against the glass before walking to his garden and placing it on a flower to recuperate.

Buchmann's kindness - he is a pollination ecologist who has studied bees for over 40 years - is about more than just returning the insect to its desert ecosystem. It's also because Buchmann believes that bees have complex feelings, and he's gathered the science to prove it.
