Perhaps you’ve wandered through a forest or strolled into a neighborhood park and found tree trunks — and wondered if counting the rings on a trunk is truly a way to know the tree's age. "Most ...

A few things on this planet are old enough to make history books look recent, and that includes some living trees that have ...

Most species of trees form annual growth rings. Researchers can count the number of rings in samples of wood extracted from living specimens and precisely determine a tree’s age.

Prospect Park Alliance arborist Malcolm Gore counted the rings on a tree stump at the top of a hill in Prospect Park. "I got to 90,” he said. Counting tree rings for age isn’t entirely ...

The question of how to tell how old an octopus is has been at the forefront of researchers' minds as they seek effective strategies to help age these animals, and thereby work to combat issues ...

Here is a method to estimate a tree's age without cutting. Noninvasive measurements can get you an acceptable age estimate for forest-grown trees.

We have a natural fascination with time—how landscapes have been carved over millennia, how our bodies grow and sag with age, how the stars traverse the sky each night. Scientists probe the layers ...

To determine a tree's age, scientists collect a core sample from the plant's base and then count its rings.

Each ring on the sequoia's surface represents one year of the tree's life, so scientists can ascertain the age of the tree by counting how many rings it has.

The summer of 2021 was the Northwest’s hottest in at least 1,000 years, according to a new study of very old trees.

IDEAS The rings inside trees are beginning to tell a different story If you cut down a tree, you can read in the wood an environmental record. Now climate change is complicating the narrative.

Dendrochronologists count these rings and can assign a ring to a specific year. This helps them determine a tree's age and make observations about the environment they live in each year.
