On 19 January 2019 ScienceAlert reported: Scientists have found evidence that plants can actually hear the buzz of passing bees and produce sweeter nectar in response to entice the flying insects in. And flowers are technically their 'ears'. Based on observations of evening primroses (Oenothera drummondii), the team behind the new study discovered that within minutes of sensing the sound waves of nearby bee wings through flower petals, the concentration of the sugar in the plant's nectar was increased by an average of 20 percent. Global Good News service views this news as a sign of rising positivity in the field of science, documenting the growth of life-supporting, evolutionary trends.

'Our results document for the first time that plants can rapidly respond to pollinator sounds in an ecologically relevant way,' write the researchers from Tel-Aviv University in Israel.

. . . As yet the work hasn't been peer-reviewed, and it's not clear precisely how the vibrations are being decoded and turned into a trigger for sweeter nectar production, but it's an intriguing first step into the study of how plants react to sounds around them.
