Here’s how lightning may help clean the air
Airplane observations show that storm clouds can generate huge quantities of air-cleansing chemicals known as oxidants.

Patterns in brain activity can identify who will struggle to read
Certain patterns of brain activity predict whether teens are strong readers or will struggle. Those diagnostic patterns show up even when doing math.

Surfing the winds would make future jet travel greener
Simple route changes could drastically cut fuel use and greenhouse-gas emissions, a new study finds.

Changing climate now threatens northern lakes year round
Lakes in northern climes are getting warmer, and that’s not good for people, plants or animals.

COVID-19 cut pollution in 2020, warming the atmosphere
Pandemic-related lockdowns briefly warmed the planet. The reason: The cleaner air carried fewer planet-cooling aerosols.
- Agriculture
Healthy soils are life-giving black gold
Scientists explain why everyone needs to value the soils beneath our feet — and why we should not view them as dirt.
- Chemistry
Let’s learn about acids and bases
Acids give away particles with positive charge. Bases accept positively charged particles. They are both critical for chemical reactions.

Explainer: What are aerosols?
We may not see them, but tiny particles and droplets cloud the air, affecting its properties. Some may be pollutants, others all-natural products.
- Climate
Can wildfires cool the climate?
Severe wildfires are becoming more common. Science is showing that the tiny particles they release into the air can alter Earth’s temperature — sometimes cooling it.

Analyze This: 2020 ties with 2016 for hottest year on record
Last year capped the warmest decade on record. It coincided with a growing increase of warming greenhouse gases in Earth’s atmosphere.

Unmasking the pandemic’s pollution problem
Discarding all the materials people use to protect themselves from COVID-19 has created a growing environmental problem.
