AI prompts offer a new tool for mapping how emotion concepts relate
How similar are "joy" and "surprise"? Conversely, how far apart are "joy" and "sadness"? We naturally organize words that express emotions—such as "happy," "afraid," and "angry"—according to similarities and differences in their meanings. However, investigating this entire
'Ecology of fear' can dramatically change the behavior of blue mussels
For a blue mussel, a good meal does not come entirely without risk. Blue mussels feed by filtering microscopic algae from seawater. But some unwelcome guests can slip in along with their food. Tiny parasite larvae can hitch a ride as the mussel pumps water in and out.
Why apples react differently to climate change than wheat
Although climate change is already having a negative impact on crops, declines in yields have so far been offset by technological advances in agriculture. For field crops that do not rely on pollinators, however, this trend appears to be reversing.
'Disarming' discovery could help scientists fight deadly fungal infections
