Ever walked from your kitchen to the living room to find your phone and then forgotten what you were looking for once you got there? Researchers think your brain is hard-wired to undergo precisely that process of forgetting.

A new study shows that IQ levels have been falling since 1975, reversing a 20th-century trend.

Like a phoenix from the ashes, fireweed is the first thing to sprout, helping reestablish areas decimated by fire and deforestation.

The towering, invasive giant hogweed has been discovered in Virginia, and residents are understandably concerned.

Researchers at the University of California finally have a scientific answer to this ages-old battle.

Could manipulating the human brain's desire for sweet foods lead to new weight control methods and better treatments for eating disorders?

A NASA study of astronaut Scott Kelly showed that spending time in space altered the expression of some of his genes. But does being on a mountain cause similar effects?

In addition to the double-stranded spiral, a four-stranded tangle, known as an i-motif, has been shown to exist throughout our genetic material.

Some kids have a lot of talent in music, art or math. Then there are those who are gifted beyond belief.

What do Donald Trump, Bob Dole and LeBron James have in common? A tendency to talk about themselves in the third person. But is it just egotism or is there a hidden benefit to saying your name rather than "I"?

A woman who gave birth posthumously also had a hole in her skull from a procedure to treat a pregnancy-related complication.

The Scandinavian countries tend to come out on top in the World Happiness Report. But the report doesn't actually ask participants if they're happy. When that question is included, the country rankings are quite different.

Tetragametic chimerism occurs when a single organism has two genetically distinct types of DNA.

And that might make it kind of tricky to pretend you're paying attention.

An ecological periodic table could help scientists predict what will happen as climate change forces ecosystems to evolve. But is such a thing possible?

Why do some people become more aggressive, even violent, after they've had a few drinks?

New research shows that homo sapiens weren't the first folks to decorate their caves with artwork. Neanderthals actually did it thousands of years earlier.

Cheddar Man was a dark-skinned, blue-eyed Stone Age Brit. You don't see those every day.

Scientists in China successfully cloned the first-ever primates using the same method that created the world's most famous sheep — a method called somatic cell nuclear transfer.

Dust traveling over the Atlantic from North Africa feeds both phytoplankton that makes the oxygen we breath and the bacteria that could kill us.

The real story about the roots of infidelity and monogamy is far more complicated than whether you have the "cheating gene."
