Is sugar as sweet to the palate as seeds are appetizing to the belly? Taste responsiveness to five food-associated carbohydrates in zoo-housed white-faced sakis, Pithecia pithecia

A mammalian blood odor component serves as an approach-avoidance cue across phylum border - from flies to humans
Abstract Chemosignals are used by predators to localize prey and by prey to avoid predators. These cues vary between species, but the odor of blood seems to be an exception and suggests the presence of an evolutionarily conserved chemosensory cue within the blood odor mixture. A blood odor component, E2D, has been shown to trigger approach responses identical to those triggered by the full blood odor in mammalian carnivores and as such, is a key candidate as a food/alarm cue in blood.
Olfactory Discrimination Ability of Human Subjects for Ten Pairs of Enantiomers
We tested the ability of human subjects to distinguish between enantiomers, i.e. odorants which are identical except for chirality. In a forced-choice triangular test procedure 20 subjects were repeatedly presented with 10 enantiomeric odor pairs and asked to identify the bottle containing the odd stimulus.
Scent is the route to the very best fruit
Study indicates that spider monkeys can trust their sense of smell to identify ripe fruit in nature Monkeys and other primates have a better sense of smell than is often claimed. Researchers at Linköping University and two German universities have studied spider monkeys - and found that they are experts at sniffing out optimally ripe fruit. At a field station in the Mexican rainforest, five spider monkeys were tested for their ability to distinguish different fruit odours.
