New research narrows down the emergence of LUCA, the common ancestor of all life on Earth, to over 4.3 billion years ago, shedding light on life's evolutionary origins.

For decades, if you wanted to get a grant from the NIH, the best route was to go to Johns Hopkins.

Many viral infections that plague humans originate from bats, yet intriguingly bats suffer no ill effects from the myriad of viruses that inhabit their bodies, a phenomenon scientists are researching in the hope of finding insights into how to moderate impacts on humans.

Possessing only essential genes, a minimal cell can reveal mechanisms and processes that are critical for the persistence and stability of life1,2. Here we report on how an engineered minimal cell3,4 contends with the forces of evolution compared with the Mycoplasma mycoides non-minimal cell from which it was synthetically derived. Mutation rates were the highest among all reported bacteria, but were not affected by genome minimization. Genome streamlining was costly, leading to a decrease in fi...
