Discovery illuminates a 120-million-year record of ancient Earth

Stanford-led expeditions to a remote area of Yukon, Canada, have uncovered a 120-million-year-long geological record of a time when land plants and complex animals first evolved and ocean oxygen levels began to approach those in the modern world.

Airborne radar reveals groundwater beneath glacier

Researchers have detected groundwater beneath a glacier in Greenland for the first time using airborne radar data. If applicable to other glaciers and ice sheets, the technique could allow for more accurate predictions of future sea-level rise.

Stanford study reveals new biomolecule

A newfound biomolecule, consisting of RNA modified by sugars, could be present in all forms of life and might contribute to autoimmune disease.

A new perspective on the genomes of archaic humans

Researchers examined 14,000 genetic differences between modern humans and our most recent ancestors at a new level of detail. They found that differences in gene activation – not just genetic code – could underlie evolution of the brain and vocal tract.
