Superhuman powers are rare, but some do exist. But what if scientists used gene manipulation to create humans with super strength and abilities in the future — like super soldiers?
Machines can translate some of the biological functions of plants into synthesizer sounds. But are these synthesized translations the same thing as music?
Hundreds of crops in developing countries are relatively unknown in the developed world because they're often hard to grow or export. But scientists have found that CRISPR editing can speed up traditional plant breeding techniques.
How does a plant — incapable of waving its arms or screaming — attract attention and spread its seed? By evolving a powerful stink or an attractive color, of course.
New research suggests modern humans owe some of our genetic resistance against RNA viruses to our Neanderthal ancestors.
The noises that others make — be it walking, chewing or breathing heavily — are very noticeable to us. Yet we seldom hear it in ourselves. Why is that?
Can a plant disappear for more than a century and then come back? Unicorn root, gone for 130 years, reappeared in the summer of 2018, completely out of the blue.
A strange, but surprisingly accurate, ancient Egyptian pregnancy test survived for millennia and was spread around Africa and Europe because it was just that effective.
Homo erectus lived for more than a million years on Earth, but laziness and lack of innovation might have been the death of them.
Turns out that evolutionary advantages can come with a price.
Composites from DNA in cold cases is helping investigators make predictions about the appearance of both suspects and victims in hopes of generating leads.
Roller coaster junkies rejoice: Riding these coasters could be a safe way to deal with your addiction to endorphins.
What happens when twins are reunited decades later? And how in the world can you explain separated twins giving their firstborn son or their family dog the same exact name?
Is your first memory of lying in a crib? You may want to revisit that. A new large study found that nearly 40 percent of participants had a first memory that was improbably early.
Scientists have found that ancient fossilized chlorophyll was dark red and purple in its concentrated form, which means that when diluted by water or soil, it would have lent a pink cast to earth and sea.
Researchers say that Otzi, the ancient man found in the Alps in 1991, lived on a diet loaded with fat to maintain warmth and energy in his cold, high-altitude environment.
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.

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.
Nine of the 13 oldest baobab trees researchers examined over the past 12 years have died. What's killing off these majestic trees?
