These ferns may be first plants known to work together as ants do
Staghorn ferns grow in massive colonies where individual plants contribute different jobs. This may make them “eusocial,” like ants or termites.

New technologies might help keep drought-prone farms green
After learning how much damage drought can do to crops, two teens designed ways to detect a thirsty plant and make sure it gets enough water.

Scientists Say: Pollen
Pollen is a mass of tiny reproductive cells. These grains combine with egg cells to form seeds — but on the way, they can make some people miserable.
- Animals
Scientists Say: Genus
A genus is a group of closely related species. It’s the first part of the two-part system called binomial nomenclature, used to name living things.

Dinosaur-killing asteroid radically changed Earth’s tropical forests
The asteroid collision initially reduced the diversity in what had been sunny tropical rainforests. In time, the forests would become permanently darker.

Scientists may have finally found how catnip repels insects
The plant deters mosquitoes and fruit flies by triggering a chemical receptor that, in some animals, senses pain and itch.

Urban gardens create a buffet for bees
City gardens provide a huge amount of nectar and pollen for pollinators, making them an essential conservation tool.
