What's up in
Biologists gained new insights into life’s genomically tumultuous past, viruses as crucial components of life, the hidden talents of complex cells and basic aspects of cognition and memory.
Throughout nature, throngs of relatively simple elements can self-organize into behaviors that seem unexpectedly complex. Scientists are beginning to understand why and how these phenomena emerge without a central organizing entity.
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.
With proteins that reversibly self-assemble into droplets, cells may control their metabolism — and harden themselves against harsh conditions.
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.
Stem cells seem to retain memories of old injuries to improve future healing. When that system goes wrong, chronic inflammation can result.
