How a fly's brain calculates its position in space
New research reveals how neurons in a fly's brain signal the direction in which the body is traveling. The cells appear to literally perform vector math in order to act as a biological compass.
Dopamine’s many roles, explained
Studying fruit flies, researchers ask how a single brain chemical can orchestrate diverse functions such as learning, motivation and movement.
Study detects origins of Huntington's disease in two-week-old human embryos
The findings shed new light on the root causes of this disease, which leads to the degeneration of neurons in midlife.
New microscopy technique reveals activity of one million neurons across the mouse brain
Using light beads microscopy, researchers can now capture images of a vast number of cells across different depths in the brain at high speed, with unprecedented clarity.
Lonely flies, like many humans, eat more and sleep less
If COVID-19 lockdowns scrambled your sleep schedule and stretched your waistline, you're not alone. Fruit flies quarantined in test tubes sleep too little and eat too much after only one week of social isolation.
Study reveals how smell receptors work
The first-ever molecular images of an olfactory receptor at work answer decades-old questions about odor recognition.
When ant colonies get bigger, new foraging behavior emerges
By increasing the size of ant colonies bit by bit, scientists identified the mechanism responsible for the evolution of mass raiding behavior.
Identifying the spark of desire in fruit flies
In Drosophila’s neural circuitry for courtship, researchers discover a configuration that enables a male fruit fly to be persistent, yet flexible in his pursuit of a female.
Scientists discover a new class of neurons for remembering faces
Our brains have sensory cells, which process the faces that we see, and memory cells dedicated to storing data from person encounters. But until now, a hybrid neuron capable of linking vision to memory—and explaining how we recall familiar faces—remained elusive.
Scientists release error-free genomes of 25 animals—with another 70,000 coming up
Scientists have launched an ambitious effort to produce high-quality reference genomes for all vertebrate species, from mammals to birds and reptiles. The result could be discoveries with implications for animal conservation as well as human health and disease.
