A new method for quantifying plant evolution reveals that after the onset of early seed plants, complexity halted for 250 million years until the diversification of flowering plants about 100 million years ago.
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.
Combining economics, psychology and studies of fertilizer application, researchers find that plants nearly follow an “equal pay for equal work” rule when giving resources to partner microbes – except when those microbes underperform.
A fossil study from Stanford University finds the diversity of life in the world’s oceans declined time and again over the past 145 million years during periods of extreme warming. Temperatures that make it hard for cold-blooded sea creatures to breathe have likely been among the biggest drivers for shifts in the distribution of marine biodiversity.
A new model of disease spread describes how competing economic and health incentives influence social contact – and vice versa. The result is a complex and dynamic epidemic trajectory.
Research based on the daily movements of people living in a contemporary hunter-gatherer society provides new evidence for links between the gendered division of labor in human societies over the past 2.5 million years and differences in the way men and women think about space.
A collection of research and insights from Stanford experts who are deciphering the mysteries and mechanisms of extinction and survival in Earth’s deep past and painting an increasingly detailed picture of life now at the brink.
A new multi-drone imaging system was put to the test in Antarctica. The task? Documenting a colony of roughly 1 million Adélie penguins.
DNA data from more than 3,300 species reveals how lichens stayed together, split up, swapped partners and changed form over 250 million years.
When survival over generations is the end game, researchers say it makes sense to undervalue long shots that could be profitable and overestimate the likelihood of rare bad outcomes.
Researchers combined avalanche physics with ecosystem data to create a computational method for predicting extreme ecological events. The method may also have applications in economics and politics.
According to Stanford University Mars experts, NASA’s latest Martian rover will drive a wave of exciting discoveries when it lands on the Red Planet – and possibly alter scientists’ understanding of the blue one it launches from.
Faculty at Stanford's School of Earth, Energy & Environmental Sciences recommend these 24 books for your summer reading.
The Chicxulub impact crater that is linked to the extinction of the dinosaurs hosted a hydrothermal system that chemically and mineralogically modified more than 100,000 cubic kilometers of Earth’s crust, according to new research.
Physicists propose that the influence of cosmic rays on early life may explain nature’s preference for a uniform “handedness” among biology’s critical molecules.
Experts from the Stanford-based Natural Capital Project explain the value of wild bees in our agricultural systems, especially in light of the increased risk murder hornets pose to domesticated honey bees.
Scientists are still trying to piece together how Earth transformed from a molten planet to one with living creatures walking around on its silicate mantle and crust. Hints lie in the strange ways materials behave under extreme temperatures and pressures.
A cohort of the Stanford Earth Young Investigators program helped advance our understanding of the relationship between the body size and circulatory systems of marine animals over a vast time frame.
Researchers have discovered an ancient plant species whose reproductive biology captures the evolution from one to two spore sizes – an essential transition to the success of the seed and flowering plants we depend on.
