New research suggests that the sugar ribose - the "R" in RNA - is probably found in comets and asteroids that zip through the solar system and may be more abundant throughout the universe than was ...
Space rocks that fell to Earth contain ribose, an essential molecule for life’s genetic machinery, and other related sugars. The finding, reported online November 18 in Proceedings of the National ...
In living organisms today, complex molecules like RNA and DNA are constructed with the help of enzymes. So how did these molecules form before life (and enzymes) existed? Why did some molecules end up ...
Joni Mitchell was right: We are stardust. Another one of the essential ingredients for life as we know it might have formed in space and then rained down on a young Earth, researchers suggest in the ...
The Thanksgiving, Christmas and New Year's holidays are a big deal in my family. There are many get-togethers, decorating, church activities, food and kids. It's fun, but by New Year's Day, I'm ...

The sugar ribose is more quickly phosphorylated compared to other sugars with the same chemical formula but a different shape. This selective phosphorylation could explain how ribose became the sugar ...
