The development of colonies of cells in choanoflagellates, water-dwelling organisms that feed on bacteria, is triggered by the presence of very low concentrations of a lipid molecule produced by certain types of bacteria.

Cauliflower mosaic virus reacts immediately when aphids feed on the host plant, and this boosts its chances of being taken up and transmitted by the insects to a new plant.

Imaging experiments reveal that some brain regions do not distinguish between actions performed using tools and those performed using the hands, while others represent these two types of action separately.

Computer simulations reveal that viral nucleic acids have an ideal structure for being packaged into outer protein shells called capsids.

Biomedical research in the US will become unsustainable unless scientists and research institutions start to question certain assumptions they have long taken for granted.

Experiments with realistic acoustic stimuli have revealed that humans distinguish salient sounds from background noise by integrating frequency and temporal information.

A statistical model is able to predict patterns of gene expression output in Drosophila embryos using only the cellular concentrations of transcription factors as input.

A computational method that can screen thousands of chemicals and predict which odorants will interact with specific odorant receptors in flies may ultimately aid the development of more effective insect repellents.

The use of metaphorical concepts is not unique to humans.

Two cooperative populations of yeast cells that cannot distinguish between cooperative partners and cheating intruders can still self-organize into clusters that exclude cheaters.
