Haunted houses. Skydiving. Scary movies.

Why do these horrifying things make some people delighted, and others, well, horrified?

Volcanoes have been crucial to life on earth. Oozing lava helped form our planet's land masses. Gases from volcanoes helped create our atmosphere. But despite the growing field of volcanology, there's still a lot we don't understand about volcanic eruptions.

That's partly because volcanoes aren't easy to study. Getting the right equipment into remote locations under unpredictable circumstances can be difficult. More important, studying active volcanos can be dangerous.

Whales are the largest animals on the planet, but they haven't always been giants. Fossil records show that ancient whales were much smaller than the currently living behemoths.

So when did whales get so big, and how?

A new study suggests it might be due to changes in climate that affected the food that some whales eat: krill and small fish. Instead of being spread throughout the ocean, lots of krill started being packed into a small area. Bigger whales were simply more efficient at eating the dense pockets of krill, and they beat out their smaller cousins.

Don't be tricked by their appearance — fangblenny fish aren't just a cute face. They use special opioid-based venom to avoid being eaten.

The fish are 2 inches long and live in places such as Australia's Great Barrier Reef. When one is caught and swallowed up by a predator, the blenny literally bites its way out. The venom disorients the bigger fish, and the blenny escapes to freedom.

Men may soon be able to take their own sperm count — at home. With a smartphone. Yes, there's an app for that.

You may be asking yourself, why?

Low sperm count is a marker for male infertility, a condition that is actually a neglected health issue worldwide, according to the World Health Organization.
