Here are links to recent science findings and claims sure to stimulate thinking and further research.

Upper Limit Set on DNA Age

Forget Jurassic Park; DNA cannot last anywhere near 65 million years, researchers say.

Explaining Inland Seas Without a Flood

The Great Salt Lake and other large extinct inland seas in the desert remain a challenge to explain by conventional geology.

Planets and Moons Beneath the Surface

Can science peel back the surfaces of objects to see what's underneath? Can they go under the observations to find the explanations?

Cambrian Soft Animal Survived Unchanged 200 Million Years

A fossil soft-bodied lobopodian has been found in Carboniferous strata in Illinois.

Pristine Wood Found in Diamond Crater

A kimberlite crater in Canada, said to be 53 million years old, yielded exquisitely preserved unfossilized wood.

Evolutionary Fish Story

Similar-looking blind fish couldn't have swum across the world, so did they evolve separately?

Geological Dates Collapse

Two papers in the journal Geology this month cast serious doubt on assumptions used to date rocks.

Rocks Don't Lie, But Liars Rock

A geologist, trying to be nice to religious people, not only deals fast and loose with rock, but rolls into circular reasoning.

Brazil's Islands in the Sky Defy Evolution

Isolated table mountains with sheer cliffs in South America should be natural laboratories for evolution. Why aren't they?

Mt. St. Helens Renewal Slow, Steady

This is an eyewitness report of ecological renewal at the volcano that erupted 32 years ago.

Palm Trees Thrived in Antarctica

Evidence for tropical trees has been found 5 km deep off the coast of Antarctica.

Since the lukewarm political response to the Rio conference, news articles indicate that climate science has a climate of its own – one that's heating up over the inability to convince the public.

Our Poisonous Moon: Better from a Distance

The moon stabilizes Earth's axis and regulates the tides, but enjoy it from a distance. Now there are more reasons you wouldn't want to live there.
