Flies use fecal deposits as pheromones
Bioluminescence imaging of fly brains reveals neurons sensitive to fly poo laced with pheromones (you can see the fecal “landmark” in the dotted circle). Need we say more?
Hippocampal memory isn’t all about place cells
Scientists have found evidence that hippocampal memories of experience are not stored in place cells.
Summer fun: how plants beat the heat
Scientists have discovered a gene that allows plants to cope with extreme heat by changing the composition of chloroplast membranes.
Freedom from fear ?♀️
Researchers discover a dopaminergic circuit in the brain that allows fear associations to disappear when there isn’t anything to be afraid of anymore.
Blue gene regulation helps plants respond properly to light
Blue light alters some gene expression in plants by changing the transcription start sites to downstream locations.
Out on a limb: the many ‘brains’ of the octopus
Learn how (neurologically) cool octopus arms are (as if you didn’t already know).
Mutation links bipolar disorder to mitochondrial disease
ANT1 mutations found in bipolar disease that affect mitochondria lead to hyperexcitable serotonergic neuronal activity in the brain.
My science communication journey in Tokyo
New contributor and nuclear physicist Sarah Naimi talks about her recent experience in science communication at a recent scicom event in Tokyo.
Gene linked to intellectual ability affects memory replay in mice
Scientists have discovered a gene in mice that allows memory replay at rest, a process necessary for forming long-lasting memories in mice.

CAPON links Alzheimer’s plaques to neurodegeneration
CAPON was found to link Aβ plaques and hippocampal neurodegeneration in mice, explaining how these two hallmarks of Alzheimer’s disease are related.

AdR blockers protect the brain from stroke damage
Treatment with adrenergic receptor antagonists (AdR blockers) was able to reduce stroke-related brain damage in mice and improve motor recovery.

Trigger region found for epileptic absence seizures
A mouse model shows that absence seizures are triggered by faulty connections between the cortex and fast-spiking neurons in the striatum.

Opto-OISI: imaging connections in the living brain
A new imaging technique called opto-OISI allows scientists to non-invasively visualize where specific neurons project in the living brain.

Flies smell through a gore-tex system
The newly named gore-tex gene is responsible for the development of nanopores that allow chemicals in the air to be detected (in flies).
