All building-block molecules of life like DNA, proteins and carbohydrates have a unique structural property that still perplexes scientists. They have what is called structural asymmetry, or chirality ...

In 1958, Bizarro made his way into comic strips—an inverted Superman who lives on a planet called Htrae, which is governed by laws opposite of those governing Earth. “I was striving, you might say, ...

Some scientists trying to create "mirror life" have stopped in their tracks. A mirror microorganism could end up being a major pathogen since immune systems wouldn't notice it. Mirror-image biology ...

Consider your hands. They are essentially identical in every respect bar one: They are mirror images of each other. Many of the molecules of life, such as proteins and DNA, have the same property.

An international group of researchers has recently warned the broader scientific community and the public of the risks of mirror life—specifically, the creation of mirror microbes by scientists in the ...

Scientists are sounding new alarms about man-made organisms whose constituent molecules are mirror images of what's found in nature and could pose unprecedented risks to humans, animals and the ...

"Mirror bacteria" being developed in labs could be a looming risk to the health of humanity, scientists have warned. These hypothetical organisms get their name from how their molecules would face the ...

(CNN) — A group of 38 scientists working in nine countries has sounded an alarm about the potential creation of mirror bacteria — synthetic organisms in which the molecular structure found in nature ...

Hold out your hands, palms up, and move them so they are on top of each other. With a little experimentation—and perhaps a few rather flamboyant gestures—you'll find that no matter what you do, your ...

Organic molecules have a property known as chirality, in which the structure can be either 'right-handed' or 'left-handed,' with one being the mirror image of the other. Llife on earth is homochiral, ...
