Neanderthal News and the Limits of Organic Material Survival

Red blood cells and DNA samples raise questions about the decay time of soft tissue and genetic material.

It's Curtains for Enceladus

The geysers of Saturn's little moon are like sheets instead of jets, spelling trouble for theories of its ancient age and possible life.

Moon, Mercury, and Magnetic Fields

After the crash of MESSENGER, magnetic fields in the solar system have become a key topic for planetary science.

Geologists Have Underestimated Catastrophes

One Colorado storm in 2013 caused hundreds or thousands of years' worth of mountain erosion. This is causing a rethink on the power of catastrophic events.

What You're Not Being Told About Earth's Magnetic Field

The simple story for the public: a dynamo creates the earth's magnetic field. The real story: complex scenario needed to start it and keep it running.

Human Epoch or Epic Hubris?

Evolutionary geologists are toying with an idea for a new time period, the "Anthropocene Epoch." What for?

Solving Moon Origin Unsolves the Last Solution

The moon's origin has been "demystified," scientists are claiming. That's what they said last time.

How Rocks Can Look Older Than They Are

Researchers find that the most common dating method can produce "spuriously old" dates.

Of Brontosaurus, Cartoons, and Revisionism

With the resurrection of Brontosaurus as a valid dinosaur name after a century of repudiation, what's a kid to think? Thoughts on science's arbitrary and tentative nature.

Messages from Mercury

With MESSENGER in its final days before impact, the innermost planet has become a familiar place.

Animal Excellence Exceeds Mere Survival

A tiny bird could live like other birds do without having to fly non-stop for 1,700 miles. Other examples abound of over-design in the animal world.

Orbital Ice Age Theory Melts

Orbital cycles do not cause ice ages, a new study suggests. Instead, the whole world experienced an ice age at the same time.

Geology Upset: Wind Carves Canyons Fast

According to a new study, wind carves canyons ten times faster than water. This has implications for theories on Mars and Earth.

Water Worlds Tempt with Life, Not Youth

More and more planets and moons are suspected of having liquid water, but what should be the logical implications?

Physical and Geological Hurdles on the Darwinian Race

Can the smooth big-bang-to-brain story of evolution jump the physical and geological hurdles along the way?
