While guppies with larger optic lobes were champions at learning visual discrimination tasks, guppies with larger telencephalons fared better when researchers switched things up.

The relative sizes of specific parts of the guppy brain may explain why some fish are better at learning certain tasks than others. 

Genetic knockout experiments reveal a role for the protein in forming and maintaining synapses between motor neurons and muscle fibers in mice.

The muscle transmembrane protein Vangl2 helps organize the development and maintenance of connections between muscles and motor neurons, a study concludes.

When Caulobacter crescentus finds itself in a nutrient-poor environment, it clusters an enzyme necessary for cell division thanks to a physical phenomenon known as phase separation so it can make better use of dwindling fuel.

When the bacterium Caulobacter crescentus runs low on fuel, it can still replicate by clustering its remaining ATP around the cell division enzyme DivJ.

An analysis of more than half a million trees reveals that many species begin to taper off seed production once they hit a certain size.

Using a transgenic fruit fly model, researchers demonstrate how epithelial barriers are maintained in living organisms despite high levels of cell turnover and death.

Mice have neurons that connect to both eyes but only propagate the signal from one or the other, simplifying the information sent to the cerebral cortex.

Neurons in the hippocampus store information on the timing of experiences in addition to their content, helping to mediate sequential memory recall, a new study shows.

Researchers identify a role for PIEZO1 in tendon adaptation, and show that people with certain versions of the Piezo1 gene tend to be better jumpers.

Genes associated with preterm birth and protecting the fetus from the mother’s immune system appear to be regulated by HAND2.

Researchers propose a mechanism by which a protein produced in the placenta may trigger blood vessel growth and enlarge fat cells.

Scientists show that an influx of noradrenaline can halt immune cells in mice.

A study finds that fast-growing species are stymied by narrow gaps, while slower-growing species can pass through and continue extending.

As they close in for the kill, the flying mammals use quieter echolocation to focus on the chase.

Whether the galls that aphids make on witch hazel leaves are red or green is associated with a gene expressed in the insects’ salivary glands.

Imaged in real time in living people, immune cells at the surface of the retina could serve as biomarkers to detect retinal and possibly neurological diseases and track their progression.

The thicker the flower petals’ cuticle, the more fragrance compounds the plant releases, according to a recent study.
