From the smallest microbe to the largest mammal, Life Science explores the origins, evolution and expansion of life in all its forms. Explore a wide range of topics from biology to genetics and evolution.
It's a wild world. One with all kinds of kooky and unexpected connections. Like the one between big brains and binge drinking. Or big brains and big hips. Here's a look at some of the head scratching-est correlations uncovered by researchers.
Who doesn't want to instantly gobble up the marshmallows floating delectably on top of their hot chocolate? As it turns out, giving in to or delaying that impulse can say a lot about you -- and your willpower. Ready to see how strong yours is?
When a well-timed joke or a clever cartoon tickles your funny bone, specific areas of your brain react to spread that mirth throughout your system. Can scientists use this knowledge to create a universal formula for comedy?
When peering thousands of years into the future, there are certain things we can count on -- evolution, extinction, plate tectonics, climate change and, quite possibly, the eruption of a supervolcano. What else does the Earth's far future hold?
Scientists know that the brain's reward center teaches humans that certain behaviors lead to pleasure, but what about those that lead to pain? A clue lies in the fact that pain isn't just a physical sensation, but an emotional and psychological one as well.
After scientists announced the first draft of the human genome, people began to wonder how our new understanding of DNA would change life. Several research institutes stated the accomplishment would revolutionize science and modern medicine -- but how, exactly?
What's more fun than looking at pictures of DNA and celebrities? Check out Dolly, dimples and dominant and recessive traits in this fun gallery charting how genetics play out in humans (and a few animals).
Why do we get mad when we get hit, or get sad when we're disappointed? Are the emotions we feel physical responses to our environments or manifestations of physical changes? There's a lot less debate on the subject than you'd think.
Imagine a time in Earth's far-flung past when organisms didn't swim through the oceans or populate the lands. Even the mighty dinosaurs hadn't arisen. Will the planet ever return to that lifeless state?
When a basketball superstar makes a 3-pointer, the multimillion-dollar paychecks go into his or her bank account. But why don't his or her parents get the glory? After all, didn't they provide the DNA that allowed for such incredible success?
We don't admit to breaking up with someone because of his looks, or that we've read our boss's private e-mails. We answer "fine" when someone asks how we are, even if we're not fine at all. Why is polite society all about the big fib?
