A Biochemist’s View of Life’s Origin Reframes Cancer and Aging
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.
Life’s First Peptides May Have Grown on RNA Strands
RNA and peptides coevolving in the primordial world might have jointly served as a precursor to the modern ribosome.
In Test Tubes, RNA Molecules Evolve Into a Tiny Ecosystem
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.
Karen Miga Fills In the Missing Pieces of Our Genome
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.
