Physics

Exploding stars scattered traces of iron over Antarctic snow

Researchers melted half a ton of snow to find just 10 atoms of a radioactive variety of iron.

Space

Two new books explore Mars — and what it means to be human

‘Once Upon a Time I Lived on Mars’ and ‘The Sirens of Mars’ are surprisingly apt reads during the pandemic.

Climate

Antarctica’s iceberg graveyard could reveal the ice sheet’s future

Drilling deep into the seafloor beneath Antarctica’s “Iceberg Alley” could reveal new clues about how quickly the continent has melted in the past.

Earth

Warm, dry winds may be straining Antarctica’s Larsen C ice shelf

Wind-induced melting that occurred during the Antarctic autumn may be accelerating the Larsen C ice shelf’s collapse, which could raise sea levels.

Earth

How the Earth-shaking theory of plate tectonics was born

Plate tectonics explains many of Earth’s geologic wonders and natural hazards — and may hold clues to the evolution of life.

Climate

One Antarctic ice shelf gets half its annual snowfall in just 10 days

Antarctica’s coasts get most of their snow from just a few big storms each year.

Climate

IPCC report warns of a bleak future for oceans and frozen regions under climate change

A new IPCC report offers dire warnings about how climate change is altering oceans, the polar regions and the high snowy mountains.

Animals

Humpback whales in the South Atlantic have recovered from near-extinction

A new count shows the population off Brazil went from about 450 in the 1950s to some 25,000 today.

Climate

Climate models agree things will get bad. Capturing just how bad is tricky

Climate models are better than ever at simulating complex interactions between ocean, air, ice and land. But scientists still aren’t really sure what the worst-case scenario might be for Earth’s future climate.

Climate

The Southern Ocean may be less of a carbon sink than we thought

The Southern Ocean’s ability to suck up much of the carbon that humans pump into the atmosphere is in question.

Oceans

Tiny bits of iron may explain why some icebergs are green

Scientists originally thought the green hue of some icebergs came from carbon particles. Instead, iron oxides may color the ice.

Earth

Ocean acidification could weaken diatoms’ glass houses

Ocean acidification may lead to smaller, lighter diatoms in seawater, which could also shrink how much carbon the tiny ocean algae can help sequester.
