Written in Ink: No Evolution

An ink sac from a fossilized Jurassic cephalopod said to be 160 million years old looks identical to those from living cuttlefish.

Earth's Magnetic Field Less Sustainable than Thought

Geophysicists have found that their favored dynamo theory for Earth's magnetic field is less stable than thought, leaving them wondering how our planet sustained its magnetic field for "geologic time."

Rapid Undersea Geology Observed

An undersea volcano near the Cook Islands was observed to grow and shrink rapidly in a fortnight, rivaling the rapid changes in Vesuvius and Mt. St. Helens.

Noah's Ark Claim Not Trustworthy

A creationist group in Hong Kong is releasing a dramatic documentary filled with fantastic claims about the discovery of Noah's Ark on Mt. Ararat. Other prominent creationists are warning of fraud and scientific malpractice.

Best Cave Art Is Still the Oldest

A new research study confirms that the exquisite cave art at Chauvet Cave is the oldest.

Coelacanth: Survival of the Dullest

A new fossil species of coelacanth was discovered in Canada. Scientists think from its tail fin shape that it was a fast swimmer–perhaps a hunter. Sadly, it was a "spectacular failure" in evolution. The luck of the evolutionary draw went to today's slow-moving, docile species.

Earth Myths with a Sprinkling of Data

Some recent articles on dating methods show that tiny bits of data can be used to generate whoppers.

Planetary Radiometric Dates 1/3 Younger

The half-lives of radioactive isotopes may not be as well-known as thought. One decay rate frequently used to date solar system objects had to be adjusted down to 66% of its former assumed value, impacting theories of planet formation.

Planet Theories vs. the Evidence

Planet theorists are putting up a valiant fight against new findings, but in some cases, the evidence seems to be winning.

Paradigm Shift: Impact Didn't Kill Dinosaurs

A new study casts doubt on whether asteroid impacts led to extinctions. It's based on re-interpreting geological evidence used to identify impacts. This finding, if sustained, would undermine the theory that an impact killed off the dinosaurs and a later impact led to the extinction of many large mammals. Even more significant, an overturn of the impact hypothesis would illustrate that scientists are capable of going off on wrong tangents for decades.

Saturn Moons Continue to Shine

Saturn just passed opposition on April 15, making it a good viewing object from Earth this season. Amateur observers with telescopes may be able to make out the moons Titan, Rhea, Dione, Iapetus, Tethys, and Enceladus. They may look like beautiful little gems from Earth, but from the Cassini spacecraft in orbit at Saturn, they are no less than astonishing. Recent observations of these moons add to the astonishment.

Is This Plant Really 30,000 Years Old?

A plant said to be 30,000 years old has been brought to life in Russia. A team resurrected a fruit from a rodent burrow in Siberian permafrost, getting it to grow into a whole plant that produces viable seeds. This is now the oldest age claim, by an order of magnitude, for plant material made to live again. Other scientists are startled that plant material could remain viable for so long, since cells have to repair their DNA continually. Other botany news bring different problems to evolutionary theory.

Dinosaurs Display Death in Watery Grave

Many dinosaur fossils show the animals with neck arched backward. This appearance is so common, it has been dubbed the "dinosaur death pose." Various theories have been invoked to explain it: dessication and final death throes among the most common. A study with chickens shows the arching neck is the automatic response of immersion in water.

More Reasons to Doubt Scientific Pronouncements

It’s unsettling to hear scientists say that long-held beliefs might be wrong, but that’s the nature of science. Scientific “findings” are tentative, not absolute. Some see this as a strength of science, but unless actual progress is demonstrated, that strength is called into question. Recent news casts doubt on various scientific methods and beliefs that had been trusted for a long time.

Lunar Upsets Challenge Paradigms

Forty years after the last moonwalkers came home, new discoveries about the moon are calling into question what scientists know about our celestial partner. But is it legitimate for scientists to invoke mystery forces when a favored theory faces falsifying evidence?
