We've been wrong about the origins of life for 90 years

For nearly nine decades, science's favorite explanation for the origin of life has been the "primordial soup". This is the idea that life began from a series of chemical reactions in a warm pond on Earth's surface, triggered ...

How did early primordial cells evolve?

Four billion years ago, soon after the planet cooled enough for life to begin, primordial cells may have replicated and divided without protein machinery or cell walls, relying instead on just a flimsy lipid membrane. New ...

Coated droplets hint at formation of early cells

(Phys.org) —Researchers at the University of Bristol have designed a chemical system that brings together alternative ideas on how primitive cells were formed on the early Earth to produce a new model of protocell organization. ...

'Game changing' Japan stem-cell study questioned

A Japanese research institute Tuesday said it was probing its own study that promised a 'game changer' way to create stem cells, a feat hailed as revolutionary for the fast-developing field.

Mouse sperm generated in rats

Making gametes such as sperm and eggs from pluripotent stem cells—primitive cells that can make all the tissues—greatly contributes to efficient reproduction of livestock animals and future assisted reproductive medicine. ...
