Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

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 ...

(Nanowerk News) Plastics or DNA: Many molecules are so long that they can form knots, much like tying shoes. Whereas it is still disputed whether right- and left-handed people prefer to tie their ...

Catalytic molecules can form metabolically active clusters by creating and following concentration gradients -- this is the result of a new study. Their model predicts the self-organization of ...

Researchers may have figured out how a crucial ingredient that cells need to produce energy could form in deep space. Calculations and lab experiments suggest that glyceric acid can arise from ...

In the iconic "Sound of Music" score, "My Favorite Things," a young Julie Andrews lists snowflakes as objects that bring her ...

What made ribose the sugar of choice for life's code? Scientists at Scripps Research may have cracked a major part of this mystery. Their experiments show that ribose binds more readily and ...

Tremendous progress in the field of prebiotic chemistry has shown how simple compounds available on ancient Earth could have given rise to the molecular building blocks of life 1. The current ...

Far from Earth, in the vast expanses of space between stars, exists a treasure trove of carbon. There, in what scientists call the “interstellar medium,” you can find a wide range of organic molecules ...

For decades, scientists have searched for clues to how life first emerged on Earth. Many theories focus on simple molecules reacting in water or on fragile protocells drifting in ancient seas. A new ...
