John Priscu’s search for life that thrives under ice took him to subglacial lakes at the South Pole. Now he has his eye on Mars and Europa.
The nervous systems of foraging and predatory animals may prompt them to move along a special kind of random path called a Lévy walk to find food efficiently when no clues are available.
Studies of collective behavior usually focus on how crowds of organisms coordinate their actions. But what if the individuals that don’t participate have just as much to tell us?
Newly discovered worlds of microbes far beneath the ocean floor, inside old basaltic rocks, could point to a greater likelihood of life elsewhere in the universe.
Recent findings add weight to the evidence that the intransitive competitions between species enrich the diversity of nature.
Only 170 million years ago, new plankton evolved. Their demand for carbon and calcium permanently transformed the seas as homes for life.
In the “underground economy” for soil nutrients, fungi strike hard bargains and punish plants that won’t meet their price.
Surviving fragments of genetic material preserved in sediments allow scientists to see the full diversity of past life — even microbes.
