The biochemist Nick Lane thinks life first evolved in hydrothermal vents where precursors of metabolism appeared before genetic information. His ideas could lead us to think differently about aging and cancer.
How did life arise on Earth? Steven Strogatz speaks with the Nobel Prize-winning biologist Jack Szostak and Betül Kaçar, a paleogeneticist and astrobiologist, to explore our best understanding of how we all got here.
RNA and peptides coevolving in the primordial world might have jointly served as a precursor to the modern ribosome.
When researchers gave a genetic molecule the ability to replicate, it evolved over time into a complex network of “hosts” and “parasites” that both competed and cooperated to survive.
Driven by her fascination with highly repetitive, hard-to-read parts of our DNA, Karen Miga led a coalition of researchers to finish sequencing the human genome after almost two decades.
Inside cells, droplets of biomolecules called condensates merge, divide and dissolve. Their dance may regulate vital processes.
