Genomic analysis of a species of zooplankton questions assumptions about speciation and gene regulation

When two animals look the same, eat the same, behave the same way, and live in similar environments, one might expect that they belong to the same species.

Scientists map soil RNA to fungal genomes to understand forest ecosystems

If a tree falls in the forest—whether or not anyone registers the sound—one thing is for sure: there are lots of fungi around. Within a forest's soil, hundreds of species decompose debris, mobilize nutrients from that ...
