Warming turns Alaskan villagers into climate migrants
Arctic warming is causing such severe erosion that an Alaskan coastal village has voted to abandon its shrinking island.

Houseplants suck up air pollutants that can sicken people
Certain indoor air pollutants can sicken people. But some houseplants can remove those chemicals from a room’s air, new data show.

Laundering clothes may send indoor pollutants outdoors
Clothing absorbs pollutants from indoor air. During washing and drying, the fabric releases those chemicals into the outdoor environment, a new study finds.

Nicotine from smoke enters body through the skin
Scientists have shown for the first time that nicotine from cigarette smoke can enter the body through bare skin from the air or contact with smoky clothes.

‘Weather bomb’ storms send tremors through Earth
Scientists have detected tiny tremors in the Earth coming from an extreme storm. One day, those tiny tremors could help reveal Earth’s innermost secrets.

Scientists Say: Permafrost
In polar regions, it gets cold enough that the very dirt will freeze, and stay frozen. This soil has a special name.
- Fossils
These may be the oldest fossils on Earth
Some mini mounds in Greenland may just be the earliest evidence of life on Earth, deposited a mere 800,000 years after our planet first formed.

Sneaky! Virus sickens plants, but helps them multiply
The cucumber mosaic virus helps tomato plants lure pollinators. When the plants multiply, the virus now gets new hosts.

Lab creates new, unexpected type of ‘firenadoes’
A newly discovered type of fiery vortex burns hot and generates little soot. Scientists suspect it could be a solution to cleaning up oil spills at sea.
- Environment
Scientists Say: Aufeis
Water keeps flowing underground even in the coldest Arctic winters. But when it comes to the surface, it chills out and forms large layers of ice — called aufeis.
- Ecosystems
Algae embedded in sea ice drive the Arctic food web
Scientists traced where zooplankton in the Arctic get their energy from. Many open ocean species rely on algae found in sea ice, which is disappearing.
- Climate
Scientists Say: Albedo
To measure how much light reflects off an object, scientists measure its albedo.
