Apart from carrying the information to encode proteins in, RNA molecules can adopt intricate 2D and 3D structures. Specifically, the same RNA molecule can switch between ON and OFF structures, ...

What made ribose the sugar of choice for life's code? Scientists at Scripps Research may have cracked a major part of this ...

The nucleolus is where ribosomal RNA (rRNA) is transcribed, processed, and assembled into the building blocks of ribosomes, the molecular machines that make proteins. Researchers discovered that rRNA ...

Losing a tooth as an adult is par for the course for many of us. The only option to replace them? Artificial substitutes. But ...

A new study provides a detailed structure of a human enzyme critical for antiviral defense and platelet function.

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 ...

Researchers demonstrated that systemic factors from young mice can rejuvenate the aging retina by alleviating cellular senescence and restoring function.

In living organisms today, complex molecules like RNA and DNA are constructed with the help of enzymes. So how did these ...

BACKGROUND: Vascular aging is an important phenotype characterized by structural and geometric remodeling. Some individuals exhibit supernormal vascular aging, associated with improved cardiovascular ...

The authors proposed two hypotheses: first, that methamphetamine induces neuroinflammation, and second, that it alters neuronal stem cell differentiation. These are valuable hypotheses, and the ...

DNA makes RNA, RNA makes protein, protein makes phenotype—was the guiding framework for understanding inheritance and disease ...

Linked to neurological disorders, repeat RNAs aggregate inside droplets but can be disassembled with an engineered piece of ...
