Embryonic cells can self-assemble into new living forms that don’t resemble the bodies they usually generate, challenging old ideas of what defines an organism.
New data indicating that Earth’s surface broke up about 3.2 billion years ago helps clarify how plate tectonics drove the evolution of complex life.
The zoologist Arik Kershenbaum argues that because some evolutionary challenges are truly universal, life throughout the cosmos may share certain features.
Researchers are tracking the different strains of SARS-CoV-2 and studying how they spread through our population and our bodies.
Unusual proteins that can quickly fold into different shapes provide cells with a novel regulatory mechanism.
A glass sponge found deep in the Pacific shows a remarkable ability to withstand compression and bending, on top of the sponge’s other unusual properties.
While the study of the SARS-CoV-2 virus was the most urgent priority, biologists also learned more about how brains process information, how to define individuality and why sleep deprivation kills.
Mistletoes have all but shut down the powerhouses of their cells. Scientists are still trying to understand the plants’ unorthodox survival strategy.
The simple insight that most changes are random had a profound effect on genetics, evolution and ecology.
