Can geoengineering plans save glaciers and slow sea level rise?
As climate change melts West Antarctica’s glaciers, scientists are proposing bold ideas to avoid devastating sea level rise. Will they work?

A daring plan to hold back the sea
Editor in chief Nancy Shute discusses the audacious ways scientists are considering to combat Earth's rising sea levels.
- Archaeology
Ancient, engraved stones may have been buried to summon the sun
Members of a Stone Age culture in Denmark may have ritually buried stones to counter the effects of a volcanic eruption.

Beneficial bacteria help these marine worms survive extreme cold
Three species of marine worms living in Antarctic waters have beneficial relationships with bacteria that produce antifreeze proteins.

A rapid shift in ocean currents could imperil the world’s largest ice shelf
Roughly the size of Spain, the Ross Ice Shelf stabilizes major glaciers along Antarctica’s coast — and is at risk of retreating, a new study finds.
- Climate
Satellite space junk might wreak havoc on the stratosphere
Hundreds of defunct satellites plunge toward Earth every year. Scientists are studying how the chemical stew left in their wake impacts the atmosphere.
- Planetary Science
An asteroid may have exploded over Antarctica about 2.5 million years ago
Tiny spherules of rock found in Antarctic ice may point to the oldest known “airburst,” or midair disintegration of an incoming asteroid.

Earth’s inner core may be changing shape
Earthquake data suggest that all or small patches of the inner core's surface may be swelling and contracting.
