Oxytocin"s role in human group relations may be shared with other primates
Oxytocin has sometimes been called "the love hormone." The past decade of research, though, has challenged this idea, meaning that this evolutionarily ancient neuropeptide hormone is involved not only in in-group love but may also be involved in out-.....»»
Scientists unravel molecular mechanism of PIN-mediated polar auxin transport
Auxin is the most important hormone in plants. It is mainly synthesized in cotyledons, young leaves and other growing tissues, and is transported to targeted issues via polar transport to regulate plant development and growth. How is this polar auxin.....»»
Using new technique, researchers make surprising discoveries about how flies" brains respond to tastes
Taste matters to fruit flies, just as it does to humans: like people, the flies tend to seek out and consume sweet-tasting foods and reject foods that taste bitter. However, little is known about how sweet and bitter tastes are represented by the bra.....»»
