Genetic diversity and long periods of time are things that are crucial for evolutionary adaptation. This made scientists wonder why invasive species, lacking genetic diversity, succeed quickly. And some ecologists are beginning to think that epigenetic factors might be modifying genes while leaving the genome intact.

Gene-Expression Indicates How Coral Reefs Will Handle Climate Change

Gene-Expression-Indicates-How-Coral-Reefs-Will-Handle-Climate-Change

Scientists have discovered a pattern of gene activity, which allows some corals to survive in higher temperatures. This suggests a way to predict how different corals will react to warmer waters, which are expected to result from climate change over the coming decades.

Darcin in Mice Urine Attracts Other Mice Repeatedly

Mice seem to be addicted to the scent of urine and repeatedly go back to spots where they found the excretions. Researchers have discovered that this behavior is triggered by a single protein in the urine of male mice.
