🐀Male and female rats like to be tickled differently - males prefer rougher play.
🤣How do we know? Rats produce ultrasonic giggles that can be monitored with a bat detector.
🧪Why is this relevant? To improve lab animal welfare.
Ah, to tickle rats for a living...♥️

❄️ Common shrews shrink their brains in winter.
🧠 The process is reversible and occurs because brain cells shrink, rather than die off. As a result, neuronal numbers stay constant and preserve brain function.
