In desperation to save the rare northern spotted owl, biologists are doing something that goes against their core — shooting another owl that's rapidly taking over spotted owl territory across the northwest.

"If we don't do it, what we're essentially doing, in my view, is dooming the spotted owl to extinction," says Lowell Diller, senior biologist for Green Diamond, a timber company.

In Search For Habitable Planets, Why Stop At 'Earth-Like'?

Kepler-22b, seen in this artist's rendering, is a planet a bit larger than Earth that orbits in the habitable zone of its star. Some researchers think there might be "superhabitable" worlds that may not resemble Earth.

In their hunt for potentially habitable planets around distant stars, scientists have been so focused on finding Earth-like planets that they're ignoring the possibility that other kinds of planets might be even friendlier to life, a new report says.

So-called superhabitable worlds wouldn't necessarily look like Earth but would nonetheless have conditions that are more suitable for life to emerge and evolve, according to the study published this month in the journal Astrobiology.

James Monroe was 18, Alexander Hamilton, 21, Marquis de Lafayette, 18, Aaron Burr, 20, Betsy Ross, 24, Gilbert Stuart, 20. Ben Franklin, of course, was much older, grander and world famous. But he was the only one.

An Old Tree Doesn't Get Taller, But Bulks Up Like A Bodybuilder

The world's biggest trees, such as this large Scots pine in Spain's Sierra de Baza range, are also the world's fastest-growing trees, according to an analysis of 403 tree species spanning six continents.

Like other animals and many living things, we humans grow when we're young and then stop growing once we mature. But trees, it turns out, are an exception to this general rule. In fact, scientists have discovered that trees grow faster the older they get.

Once trees reach a certain height, they do stop getting taller. So many foresters figured that tree growth — and girth — also slowed with age.
