Younger Americans tend to be comfortable relying on ride services and foregoing car ownership.
Using ride-hailing services full-time would mean avoiding the hassles of owning a car. But it could cost less, too – depending on how you value your time otherwise spent behind the wheel.
New research shows that noise pollution in US cities is concentrated in poor and minority communities. Beyond regulating airplane noise, the US has done relatively little to curb noise pollution.

A trade spat could jack up the cost of going solar, killing jobs and obstructing efforts to do something about climate change.

A new study shows that sustainable fish farming in deep ocean waters could produce as much seafood as all of the world's wild fisheries, in a space the size of Lake Michigan or Africa's Lake Victoria.
When the United States was settled, nearly everyone was a farmer. Today only 2 percent of Americans live on farms, and many of us are illiterate about where food comes from or what kinds are healthy.
Ad hoc boat rescues have become critical parts of disaster response efforts, a trend first responders have officially embraced.
The Department of Energy's review of the electricity grid finds natural gas, rather than renewables, has hurt coal and nuclear power. But that's only half the story of the changes underway.
Snowshoe hares in warmer zones have thinner fur, and some are not turning white in winter. As climate change warms the Northeast, will this species adapt?
Instead of building a wall on the US-Mexico border, a landscape architect calls for restoring the Rio Grande and turning its course into an international park – an idea first proposed in the 1930s.
More and more research shows that we are likely to pass the 2 degree Celsius temperature limit much of the world has agreed on. Where did that limit come from, and what if we miss it?
Why is it so hard to reach consensus about how to slow climate change? Multiple time lags get in the way: some make it hard to convey the risk, while others prolong the search for solutions.
In Puerto Rico the Trump administration's 'energy dominance' policy echoes colonial practices by fast-forwarding fossil fuel projects over community resistance.
Study uses satellite data to add to growing evidence that nighttime light exposure raises risk of breast cancer, with the strongest link among young women.
A new study shows that anchovies – key food for larger fish – are attracted to plastic trash because it smells like food. This suggests that toxic substances in plastic could move up through food chains.
Why assembling two teams to debate climate change is all about political spectacle and sowing doubt – and has nothing to do with actual climate science.
China has started exporting cooked chicken meat to the United States. Is it safe to eat? An agriculture extension specialist discusses possible concerns about food safety and contamination.
Nuclear power plants don't just pump out steady, carbon-free electricity; they also help produce the people the US needs for nuclear weapons inspections.
When utilities plan investments, they think decades ahead. A recent study shows why power companies should be spending more on renewables despite the Trump administration's tilt toward fossil fuels.
An experiment in getting people to care about climate change uses slick videos, charismatic scientists and calls to action.
New research shows that older people are especially at risk during and after natural disasters, and may need medical help or other support well after relief operations end.
Bio-inspiration takes cues from natural structures that do certain things very effectively. One example: the strong but flexible fibers that sea sponges use to anchor themselves to the ocean floor.
If history is a guide, policies that promote wind power expansion will lead to lower prices – potentially beating fossil fuels in the US by 2030.
Nitrogen and phosphorus are polluting US waters, creating algae blooms and dead zones. New research confirms that voluntary steps are failing in the Gulf of Mexico and unlikely to work in Lake Erie.
America's drinking water infrastructure is aging and needs billions of dollars in upgrades. Two extension educators urge consumers to monitor their water and have it tested if they suspect problems.
The US wants to invest in more infrastructure to handle our rainfall and melted snow. Stormwater credits could help cut costs and protect the environment.
Trump administration officials argue that states can regulate more effectively than the federal government. But without leadership from the top, federalism may allow red states to avoid acting.
The American Society of Civil Engineers gives US infrastructure a D+. What is it that we're doing wrong?
Many Americans live in transit deserts – areas where demand for transit exceeds the supply. To fix these gaps, we need to find and map them so agencies can add transit options in the right places.
Shifting to plug-in cars wouldn't be enough to max out global oil consumption by 2040. But it could help make that happen if cities pitch in and ride-sharing doesn't crowd out public transportation.
Can federal agencies stack advisory panels with friendly members? Some have tried, but a scientist who has advised many administrations says they will produce bad policies that lack broad support.
The peach looms large in Georgia history and lore. Today the Georgia peach crop is dwindling, but its history remains deeply entwined with Southern history, politics and culture.
A recent study finds that noise from human activities is intruding into many parks and other protected areas. Creating quiet zones and noise corridors can help reduce impacts from noise pollution.
According to a new UN report, more than two billion people around the world do not have access to clean, safe water in their homes. Most of the work of getting water falls to women and girls.
Are all people entitled to live in a clean and healthy environment? A legal scholar says yes, and argues for using this principle to address damage from polluting industries in Appalachia.
Research shows that bringing nature indoors, in the form of movement created by light, wind and water, makes occupants calmer and more productive. It also could promote interest in sustainable design.
Cleaning up and reusing contaminated sites, known as brownfields, can create jobs and promote economic growth. But it also can drive gentrification that prices out low-income residents.
The Trump administration has set a new national policy: energy dominance. But can the US really dominate other countries through fossil fuel exports?
Set aside the politics. If by some miracle we turned off carbon emissions immediately, how would the climate respond?
How fast can the US transition to clean energy and with what energy sources? Here's why an impassioned debate among energy wonks matters to the rest of us.
The world's oceans are home to innumerable life forms, from sponges to sea lions, and scientists have many creative ways of studying them.
As the rich move away from disaster-prone areas, the poor may be left behind.
