Archaeological site reveals how Neolithic man adapted to climate change
New research shows how early farmers adapted to a well-documented climate shift 8,200 years ago. The results demonstrate the value of using lipid biomarkers to explore ancient societies’ responses to climate change.
How would a border wall affect wildlife?
Federal plans to complete a continuous wall along the U.S.-Mexico boundary would threaten the existence of numerous plant and animal species. Stanford’s Paul Ehrlich and Rodolfo Dirzo look at the region’s unique natural ecosystems, and what they have to lose.
Nectar research reveals how species coexist
Different species almost always coexist – whether it’s big animals on the plains, bugs in a jungle or yeasts in flower nectar – but how that works is complicated. Now, Stanford researchers have teased apart competing theories of how species live together.
Overlooked process in bacteria may shed light on ancient environments
Geologists assume when they find molecules called sterols in soils or rocks they indicate the presence of plants, animals or fungi in ancient environments. But discovering how some bacteria also produce and modify sterols could change those interpretations.
When did humans start influencing biodiversity? Earlier than we thought
Fossil study finds early human activity — not climate shifts — led to the decline of large animals before the first human migrations out of Africa. The findings add to concerns about continued biodiversity loss.
Scientists discover first subglacial lakes in Canadian Arctic
Super salty water beneath ice may be analogue for habitat for life on other planets
Stanford researchers learn why aquatic mammals need to be big, but not too big
Examining body sizes of ancient and modern aquatic mammals and their terrestrial counterparts reveals that life in water restricts mammals to a narrow range of body sizes – big enough to stay warm, but not so big they can’t find enough food.
Extinct Lakes of the American West
Extinct lake landforms provide clues of climate change over millions of years and inform our understanding of rainfall patterns and water management in the arid American West.
Learning through fieldwork in Palau
Undergraduates study links between human and natural systems in a program that puts them up close with corals. Stanford Earth professor Rob Dunbar is a lead instructor.
Insects took off when they evolved wings
Now buzzing and whizzing around every continent, insects were mysteriously scarce in the fossil record until 325 million years ago – when they first took flight and, according to a new study, evolutionarily took off.
Puzzle at the center of the Earth
Mysterious patches on the planet’s core that dampen seismic waves could be the result of ancient seawater chemically reacting with iron under extreme conditions.
Scientists make first observations of how a meteor-like shock turns silica into glass
Research with SLAC’s X-ray laser simulates what happens when a meteor hits Earth’s crust. The results suggest that scientists studying impact sites have been overestimating the sizes of the meteors that made them.
Diversity of large animals plays an important role in carbon cycle
With abundant data on plants, large animals and their activity, and carbon soil levels in the Amazon, Stanford research suggests that large animal diversity influences carbon stocks and contributes to climate change mitigation.
Radiated corals of Bikini Atoll may hold insights on cancer
Stanford researchers are exploring how corals that re-colonized Bikini Atoll after nuclear bomb tests 70 years ago have adapted to persistent radiation. Their work is featured in a PBS series.
What a warming planet means for mosquito-borne diseases
A new analysis by Stanford researchers reveals that the ideal temperature for the spread of mosquito-born diseases like dengue, chikungunya and Zika is 29 degrees C. This finding helps predict disease outbreaks in a warming world.
Organic carbon can resist breakdown in underground environments
A new study reveals that organic matter whose breakdown would yield only minimal energy for hungry microorganisms preferentially builds up in floodplains, illuminating a new mechanism of carbon sequestration.
Ancient Colorado earthquake triggered by dino-killing asteroid?
The dino-killing asteroid that crashed into the Yucatan Peninsula of Mexico could have generated massive seismic waves that triggered earthquakes as far away as Colorado, in a region where no previous fault existed, according to research by Stanford Earth's Norm Sleep.
First oceans may have been acidic
A model of ion flux in the oceans shows carbon dioxide driving ocean acidity.
Poor outlook for biodiversity in Antarctica
A comparison of Antarctic biodiversity and its management with global trends finds that it is more similar to the rest of the world than previously believed.
