Wild Bumblebees Show Capability for Logical Reasoning

Hello and welcome to Thursday’s newsletter,

As the temperature rises, please remember to stay hydrated. According to the CDC, for every 15-20 minutes in the heat, one should drink 1 cup (8 ounces) of water, and drinking at shorter intervals is more effective than drinking large amounts infrequently. Warning: Do not drink more than 48 oz per hour! This can lead to a medical emergency, as consuming too much fluid (whether it's water or other beverages) can cause an imbalance in salt concentrations in the blood.
