The policy could provide a much-needed hedge against a future AI dystopia—but only if it’s designed the right way.

Scientists have uncovered a surprisingly simple “tissue code”: five rules that choreograph when, where, and how cells divide, move, and die, allowing organs like the colon to remain flawlessly ...

The genetic code is central to life. With minor variations, everything uses the same sets of three DNA bases to encode the same 20 amino acids. We have discovered no major exceptions to this, leading ...

Taking a fresh approach at an old problem, Sawsan Wehbi, a doctoral student in the Genetics Graduate Interdisciplinary Program at the University of Arizona, discovered strong evidence that the ...

Despite awe-inspiring diversity, nearly every lifeform—from bacteria to blue whales—shares the same genetic code. How and when this code came about has been the subject of much scientific controversy.

The blue blood of threatened horseshoe crabs contains a chemical essential for testing the safety of vaccines. So these ancient creatures are highly sought after by pharmaceutical companies worldwide, ...

The advancement of genetic code expansion (GCE) technology is attributed to the establishment of specific aminoacyl-tRNA synthetase/tRNA pairs. While earlier improvements mainly focused on ...

Prokaryotic genomes are replete with mobile genetic elements (MGE) that span a continuum of replication autonomy. On numerous occasions during microbial evolution, diverse MGE lose their autonomy ...

The standard genetic code (SGC) is common to all sufficiently explored Earth biota, suggesting a common origin for protein biosynthesis in every known organism. The ancient events leading to this near ...

New research suggests that some very specific fears may be genetically encoded in dogs. I first encountered a possible instance of this a while back when an acquaintance joined me at a coffee shop ...
