Serotonergic cells innervating the Drosophila antennal lobe are inhibited by odors and modulate olfactory responses in conjunction with the entire serotonergic network.

FIB-SEM is used to identify comprehensively and reconstruct 192 neurons and their complete connectome for glomerulus VA1v of the Drosophila antennal lobe, in particular to reconstruct its local interneurons.

Neurons in the fruit fly olfactory system respond most strongly to the sudden appearance of an odor, and to odors that are changing rapidly in strength, but are relatively insensitive to the absolute levels of an odor.

A comprehensive synapse-level analysis of a fly central-brain region has led to the identification of molecules that are necessary for mediating the normal density of connections.

The lateral horn can be classified into three functional odor response domains that decode opposing hedonic valences and odor intensity.

Sexual arousal in flies counteracts the effects of sleep deprivation.

Why does the human regulatory system, which evolution tuned for small satisfactions, now constantly demand 'more'?

Guidelines governing research into embryos need to be updated in a way that reflects the moral status of synthetic human entities generated using the methods of synthetic biology.

Dubbed the 'green yeast', the model alga C. reinhardtii has profoundly advanced many areas of biology, but much remains to be learnt about its life in the wild.
