Female fruit flies use male pheromones to assess their social context and shorten the amount of time they store sperm after mating, allowing them to re-mate sooner, according to a new study.

A team of bioengineers at Instituto Gulbenkian de Ciência, in Portugal, has found that inactivating the Tgfbr1 gene in mouse embryos results in altered development in the trunk to tail region.
Whereas humans have one receptor on their tongues that can detect all sorts of sweet things, from real sugar to artificial sweeteners like aspartame, insects have many receptors that each detect specific types of sugars. ...

In biochemistry, a receptor is a protein molecule, embedded in either the plasma membrane or cytoplasm of a cell, to which a mobile signaling (or "signal") molecule may attach. A molecule which binds to a receptor is called a "ligand," and may be a peptide (such as a neurotransmitter), a hormone, a pharmaceutical drug, or a toxin, and when such binding occurs, the receptor undergoes a conformational change which ordinarily initiates a cellular response. However, some ligands merely block receptors without inducing any response (e.g. antagonists). Ligand-induced changes in receptors result in physiological changes which constitute the biological activity of the ligands.
