When the first spark of life emerged on a young, ocean-covered Earth some four billion years ago, it didn’t happen at once.

Cells use proteins to make other proteins - new research could explain how the first proteins arose without other enzymes ...

More than four billion years ago, Earth was a very different place. Pools of water froze and thawed in cycles, minerals ...

New study reveals how aminoacyl-thiols may have kickstarted protein synthesis, shedding light on life's origins.

A series of structures of the eukaryotic protein-synthesis machinery are imaged at high resolution in defined states of the elongation phase of protein synthesis. Analysis suggests that there are ...

Scientists at the University of California, Santa Cruz, have trapped the ribosome, a protein-building molecular machine essential to all life, in a key transitional state that has long eluded ...

Chemists have developed a protocol to rapidly produce protein chains up to 164 amino acids long. The flow-based technology could speed up drug development and allow scientists to design novel protein ...
