A report that a fish can pass the “mirror test” for self-awareness reignites debates about how to define and measure that elusive quality.
Neither animal, plant, fungus nor familiar protozoan, a strange microbe that sits in its own “supra-kingdom” of life foretells incredible biodiversity yet to be discovered by new sequencing technologies.
As it becomes clear that the body’s cells have more diverse regenerative capabilities than expected, experts have had to reconsider their approach to stem cell research.
Some researchers are using a complexity framework thought to be purely theoretical to understand evolutionary dynamics in biological and computational systems.
How does evolution select the fittest “individuals” when they are ecosystems made up of hosts and their microbiomes? Biologist debate the need to revise theories.
For 50 years, evolutionary theory has emphasized the importance of neutral mutations rather than adaptive ones at the level of DNA. Real genomic data challenges that assumption.
Using a new CRISPR-based technique, researchers are examining how the position of DNA within the nucleus affects gene expression and cell function.
