Trawlers intermix with whale ‘supergroup’ in Southern Ocean

Scientists observed close to 1,000 fin whales foraging near Antarctica, while fishing vessels trawled for krill in their midst. Without action, such encounters are likely to become more common as this endangered species recovers and krill harvesting intensifies in the Southern Ocean.

AI predicts global warming will exceed 1.5 degrees in 2030s

Artificial intelligence provides new evidence our planet will cross the global warming threshold of 1.5 degrees Celsius within 10 to 15 years. Even with low emissions, we could see 2 C of warming. But a future with less warming remains within reach.

Mystery of impediment to a next-gen battery solved

In the race for fast-charging, energy-dense lithium metal batteries, researchers discovered why the promising solid electrolyte version has not performed as hoped. This could help new designs – and eventually battery production – avoid the problem.

Droughts increase costs for low-income households

According to a recent study, when providers act to curtail water use or invest in new infrastructure because of a drought, bills can rise for low-income households and drop for high-income households.

Volcano detective

As a young adult, Ayla Pamukçu found herself at a crossroads between college and culinary school. Thanks in part to an influential box of rocks, she chose a research path that eventually led to a career studying the inner workings of the Earth.

Stanford Doerr School of Sustainability —

Top 10 sustainability research stories of 2022

The Stanford Doerr School of Sustainability looks back at the research highlights from the units that came together to form the new school, which launched in September.

Solar panels largely confined to wealthy Americans

Tax rebates for installing residential solar power have done little to spur adoption in low-income communities in the United States, while a less common incentive seems to succeed, according to new research using AI and satellite images.

The cleanest drinking water is recycled

New research shows treated wastewater can be safer and more dependable than common tap water sources, including rivers and groundwater.

Beaver dams buffer rivers against climate extremes

American beaver populations are booming in the western United States as conditions grow hotter and drier. New research shows their prolific dam building benefits river water quality so much, it outweighs the damaging influence of climate-driven droughts.

For a longer-lasting battery, make the most of each cell

The secret to long life for rechargeable batteries may lie in an embrace of difference. New modeling of how lithium-ion cells in a pack degrade show a way to tailor charging to each cell’s capacity so EV batteries can handle more charge cycles and stave off failure.

Whales eat colossal amounts of microplastics

Analysis of ocean plastic pollution and whale foraging behavior tracked with noninvasive tags shows whales are ingesting tiny specks of plastic in far bigger quantities than previously thought, and nearly all of it comes from the animals they eat – not the water they gulp.

Predicting drought development using plant processes

Based on new analyses of satellite data, scientists have found that hydrologic conditions that increase flash drought risk occur more often than current models predict. The research also shows that incorporating how plants change soil structures can improve Earth system models.

Sustainable health care

The health care sector accounts for almost 10% of U.S. emissions and is one of the country’s largest producers of waste. What can be done to make it more sustainable, while maintaining safety?

Wildfire smoke exposure hurts learning outcomes

Pollution from wildfires is linked to lower test scores and possibly lower future earnings for kids growing up with more smoke days at school, a new study finds. Impacts of smoke exposure on earnings are disproportionately borne by economically disadvantaged communities of color.

Charging cars at home at night is not the way to go

The move to electric vehicles will result in large costs for generating, transmitting, and storing more power. Shifting current EV charging from home to work and night to day could cut costs and help the grid, according to a new Stanford study.

Wildfire smoke is unraveling decades of air quality gains

Stanford researchers have developed an AI model for predicting dangerous particle pollution to help track the American West’s rapidly worsening wildfire smoke. The detailed results show millions of Americans are routinely exposed to pollution at levels rarely seen just a decade ago.

Are we missing a crucial component of sea-level rise?

Across Antarctica, some parts of the base of the ice sheet are frozen, while others are thawed. Scientists show that if some currently frozen areas were also to thaw, it could increase ice loss from glaciers that are not currently major sea-level contributors.

New ‘lab on a chip’ may accelerate carbon storage efforts

A tiny new device allows scientists to directly observe and quantify how rocks change in the presence of acids, enabling more accurate assessments of sites for underground storage of carbon dioxide, hydrogen, and industrial waste.

Geological activity can rapidly change deep microbial communities

New research reveals that, rather than being influenced only by environmental conditions, deep subsurface microbial communities can transform because of geological movements. The findings advance our understanding of subsurface microorganisms, which comprise up to half of all living material on the planet.

Next-gen battery solutions

A new mathematical model has brought together the physics and chemistry of highly promising lithium-metal batteries, providing researchers with plausible, fresh solutions to a problem known to cause degradation and failure.

When will California’s San Joaquin Valley stop sinking?

A Stanford University study simulates 65 years of land subsidence, or sinking, caused by groundwater depletion in California’s San Joaquin Valley. The results suggest significant sinking may continue for centuries after water levels stop declining but could slow within a few years if aquifers recover.

Small modular reactors produce high levels of nuclear waste

Small modular reactors, long touted as the future of nuclear energy, will actually generate more radioactive waste than conventional nuclear power plants, according to research from Stanford and the University of British Columbia.

Four questions for Desiree LaBeaud

The Stanford infectious disease physician and epidemiologist reacts to recent news about the effects of plastic on human health.

Research initiative on hydrogen for decarbonization

The Stanford Energy Hydrogen Initiative will fund research to evaluate hydrogen’s role in the transition to sustainable energy and the technologies, policies, and financial mechanisms to fulfill that role.
