Repeated sexual failures cause social stress in fruit flies

Repeated failures to reproduce make fruit flies stressed and frustrated, which in turn makes them less resilient to other types of stress, Julia Ryvkin at Bar-Ilan University and colleagues report in PLOS Genetics.

First wireless map of worm's nervous system revealed

Researchers have built the first ever map showing how every single neuron in the nervous system of a tiny worm communicates wirelessly. This huge step forward in understanding how neurons communicate through extremely short ...

Team rewires a behavioral circuit in a worm using hydra parts

For two people to communicate in a loud, crowded room, they need to be standing side by side. The same is often true for neurons in the brain. But the same way a cell phone allows two people to communicate clearly across ...

Harnessing psyllid peptides to fight citrus greening disease

Citrus greening disease, also called huanglongbing (HLB), is a bacterial infection of citrus trees that results in small, misshapen and sour fruits that are unsuitable for consumption, ultimately killing the tree. Because ...

Substances associated with bee ferocity reported

Brazilian researchers may have discovered why Africanized honeybees are so aggressive. The scientists detected higher levels of certain chemical substances in the brains of Africanized honeybees than in gentler strains of ...

Inside the brains of killer bees

Africanized honeybees, commonly known as "killer bees," are much more aggressive than their European counterparts. Now researchers have examined neuropeptide changes that take place in Africanized honeybees' brains during ...

Neuropeptide controls roundworms' backward movement

A study of genetically diverse worms finds that the length of their backward movement is under the control of a small protein called a neuropeptide that fluctuates in response to food availability. The research, published ...
