Deadly heat: Expected by century’s end, it’s here already

Instances of hot and humid conditions that threaten human lives are on the rise.

Environment

Let’s learn about rain

People need rain for their crops and their drinking fountains. But there sometimes can be too much of a good thing.

Oceans

Scientists Say: Tsunami

This is a series of ocean waves triggered by an underwater earthquake or volcano. The event starts as small waves, but those waves can grow as they approach land.

Animals

When prey get scarce, these jellies become cannibals

Invasive comb jellies may feast on their larvae if massive population booms in summer deplete their prey.

Environment

Fossil fuels appear to release far more methane than we thought

Ice cores reveal less methane than expected. This suggests today’s fossil fuel industry is responsible for nearly all of the methane emissions from natural sources today.

CO₂ emissions have nosedived as COVID-19 keeps people home

The COVID-19 pandemic restricted travel that can pollute the air. By April, travel-related daily emissions of greenhouse gases was back to 2006 levels.

Environment

Pesticides can have long-term impact on bumblebee learning

Pesticide-laced nectar and pollen can permanently harm the brains of baby bumblebees.

Earth

Did rain put the Kilauea volcano’s lava-making into overdrive?

Scientists share strongly conflicting opinions about why Hawaii’s Kilauea volcano spewed an overabundance of lava in 2018.

Earth

Let’s learn about earthquakes

Dozens of quakes happen every day, but most aren’t big enough for people to notice.

Earth

A rainforest once grew near the South Pole

A forest flourished within 1,000 kilometers of the South Pole. That was a while ago, as in millions of years ago.

Materials Science

This ‘living’ concrete slurps up a greenhouse gas

Microbes help harden a mix of sand and gelatin into a living concrete that could interact with people and the environment in great new ways.

Earth

Scientists Say: Jurassic

During this time from about 200 million to 145 million years ago, dinosaurs reigned and many animals evolved, including birds and some early mammals.
