With climate change, daily temperatures are on the rise, which affects sap flow and sugar content. By 2100, the maple syrup season in eastern North America may be one month earlier than it was during 1950 and 2017, according to a new study.

Neuroscientists have analyzed how people react when they listen to a range of different sounds, the aim being to establish the extent to which repetitive sound frequencies are considered unpleasant. Their results showed that the conventional sound-processing circuit is activated but that the cortical and sub-cortical areas involved in the processing of salience and aversion are also solicited. This explains why the brain goes into a state of alert on hearing this type of sound.
