Tree ring research: Three researchers on a raft
WITH PODCAST

When trees talk

We think of trees as silent sentinels, watching as the world goes by and the ages pass. But what if you could interview them about what they have seen?

Aeromonas. Sushi.

How safe is your sushi?

Bacteria in raw seafood can make you sick. Seafood can also spread bacteria that are resistant to antibiotics.

WITH PODCAST

Listening to Leviathans

Nineteenth-century Norwegian technology helped bring large whale populations to the brink of extinction. Can 21st-century technology help save them?

Supergenes helped bring alien plant to Norway

The plant is called common ragweed, and if you are allergic to pollen, you should probably pay extra close attention. This is one of the invasive plants that supergenes have brought to Norway.

NOTES

Tracking whales as they cruise the Arctic

For the first time ever, researchers have been able to track eight fin whales in near real time for five hours, as they swam along a stretch of fibre-optic cable line in the Arctic. The breakthrough suggests that fibre-optic cable networks could be harnessed to help prevent whale deaths by ship strikes.

Moose can play a big role in global warming

Climate researchers have long known that large animals, like moose, could play a role in how much the Earth will warm due to climate change. But the question is, how much? New research shows the answer can be a lot.

Just one degree can change a species

Even seemingly small changes in the climate can change the number of animals and plants in an area and how species behave, new research shows. Natural history collections provide valuable insights.
