• Why don’t penguins freeze in the winter?

• Penguins reduce blood flow to their feet by varying the diameter of arterial vessels. This keeps their feet a degree or two above freezing, minimizing heat loss, while escaping frostbite.

Do you wonder?

• What is a hiccup?

• There is no known function for the reflex we call a hiccup. Low levels of carbon dioxide in the blood make hiccups worse, suggesting their function may be to control breathing.

• Holding your breath presumably stops hiccups by raising the concentration of Carbon Dioxide in the arteries.

And what about…• If you run through the rain will you get less

wet than if you walk? • The number of raindrops falling on you

depends upon how long you are out in the rain. So if you run, presumably you will be out in the rain for less time.

• However, by running you will get more rain on your head in a shorter time and thus be wetter.

• So generally, if it is a light shower, walk, but run in a heavy downpour.

I’ve always wanted to know…

• How does a squirrel find the nuts it has buried?

• Squirrels have a good spatial memory and make a mental map of where they buried the nuts, remembering landmarks and the environment.

• They also use their acute sense of smell to help them locate their food.
