Saving power to use later lets consumers, businesses and utilities generate energy when it’s cheap and deliver it when they need it most. There’s not much of it today, but the industry is growing fast.
Some information on the climate has been obscured.

Many socks, towels and other textiles are treated with silver nanoparticles to kill germs and odors. When the silver washes out, it can pollute waterways. Two chemists propose a way to collect it from wastewater.

Gentrification is not the only path for improving urban neighborhoods. A cleanup in Brooklyn and Queens offers another, more inclusive model that scholars have dubbed ‘just green enough.’

Even in cities with good public transportation, some areas can be ‘transit deserts,’ where demand exceeds supply. Living in these zones makes it hard to access good jobs, health care and other services.

Sea snakes spend their lives in the water, giving birth to live young at sea, so why are they only found in some of the world’s oceans? The answer lies in a combination of climate and geography.
Farmed fish like these carp now make an important contribution to global food security.

Many critics say that fish farms mainly sell their output to wealthy countries and don’t provide much benefit to poor people in producing countries. Three aquaculture experts show why this view is wrong.

An ambitious plan to cut the flow of nutrients into the Chesapeake Bay has produced historic regrowth of underwater seagrasses. These results offer hope for other polluted water bodies.
Nuclear reactors line the bank of the Columbia River at the Hanford site in 1960.

During the Cold War, the US built nuclear weapons at a network of secretive sites across the nation. Some are still heavily polluted and threaten public health today.
Venus flytrap plants have ‘traps’ that snap shut on insect prey. But they also rely on insects for pollination. New research suggests how the plant avoids eating its allies.
The Amazon rainforest is fed by a rich network of creeks, streams and rivers. Informal road construction is now endangering this critical ecosystem.

Thousands of dirt roads crisscross the Brazilian Amazon, serving ranchers, loggers and miners. The area’s fragile waterways — and the spectacular fish that live in them — pay a high price.
Knowledge has been democratized. What does that mean for scientists?
