Nature & Wildlife

Birds can sleep in flight. Some species, like swifts and frigatebirds, spend months in the air and only land to breed. Researchers found that they nap in short bursts while gliding.

Trees communicate through underground fungal networks. Scientists call it the “Wood Wide Web”—roots connect via mycorrhizal fungi and share nutrients and even warning signals.

Honeybees do a “waggle dance” to tell others where flowers are. The angle and duration of the dance encode direction and distance to the food source.

Dolphins use unique whistles as names. Each animal has a signature call that others use to address it. Octopuses have three hearts and blue blood; two hearts pump blood through the gills, the third through the body.
