Two tiny ant fossils recovered in southern Saskatchewan are helping scientists better understand the evolutionary history of modern ants. Ant fossils dating from 72–56 million years ago are rare. What happened to insects ...
Satellite measurements detected declining photosynthetic activity in Western U.S. forests two years before bark beetle mortality appeared in aerial detection surveys, according to new University of Utah-led research.
About 200 million years ago, furry, little egg-laying creatures evolved the ability to feed their offspring with a secretion from special glands: milk. Their evolutionary journey continued, and by about 160 million years ...
When researchers at HHMI's Janelia Research Campus set out to create a map of all the neurons in the fruit fly brain in 2008, many in the scientific community thought they were out of their minds.
More than 80% of North American forests could face greater threats from pests and diseases by midcentury, a University of British Columbia-led study finds. If global emissions continue unchecked, rising temperatures and shifting ...
In a quiet summer garden, a caterpillar perches on a branch, munching serenely on leaves. A moment later, it freezes. It senses danger—and just in time. From behind, a wasp approaches, sizing up its prey.
Why do some groups of organisms contain thousands of species while others have only a handful? Evolutionary biologists have spent decades trying to answer this question using mathematical models that estimate how biological ...
The Democratic Republic of Congo's (DRC) tropical forests stretch across an extraordinary landscape of rivers, wetlands, savannas and towering trees. But in a forest this vast, biodiversity doesn't exist on a single plane. ...
The honey bee has held a special place in vision research. It is one of the best-studied insects, and much of what scientists know about how bees perceive the world is based on studies of honey bees.
High above the fields of the Morven Sustainability Lab, drones equipped with heat and light sensors are changing what it means to farm smarter. This month, researchers and students from the University of Virginia, NASA and ...
