Discovery Upsets Geological Dating
November 17, 2011
For a long time, geologists have used microscopic crystals called zircons as “time capsules” for dating rock strata. The tiny crystals are so durable it was believed they were virtually impermeable. Now, however, inclusions inside the zircons appear to be vastly different in age. This could have drastic effects on how certain formations are dated.

Whale Fossils: Challenge or Support for Evolution?
November 14, 2011
When most fossils consist of small shelly creatures, finding a whale is indeed big news. Two whale fossil discoveries on opposite sides of the world are spectacular and puzzling. Do they support the theory that whales evolved from land mammals?

Space Physics and Fables
November 9, 2011
Physics is supposed to be the king of “hard science” because of its precise mathematics, predictability and falsifiability. When transferred off our planet, however, it seems speculation is the order of the day.

It Emerged from Warm Mud
October 31, 2011
How would you feel if evolutionists told you that you came from mud? It’s probably not any worse than other notions they’ve been telling mankind for years: we all came from slime, primordial soup, volcanoes, or were seeded here by space aliens. How these notions find their way into science is an interesting question.

New Worlds
October 28, 2011
Members of our solar system that were little more than points of light for decades or centuries have now become familiar family members, seen up close and personal by spacecraft. Here are introductions to three worlds that are no longer mere names in a catalog. Even the names of members in this trio may be unfamiliar to some. They’re worth getting to know.

NCSE Takes on Creation Geologists
October 23, 2011
The science of geology operates in parallel universes. There are the mainstream, secular geologists in the Geological Society of America who have complete hegemony in the secular universities, the mainline journals and the secular press. Then there are the creation geologists, who publish in their own journals; these hardly enter the awareness of the other geologists. Once in a while, though, like disturbances in the Force, emanations from the creation universe into the secular universe are felt. The National Center for Science Education has become so alarmed at these emanations that they have warned secular geologists to (1) pay them no attention, and (2) pay attention.

Ski Enceladus
October 22, 2011
Want the ultimate in powder snow? Ski Enceladus, a little moon of Saturn. The snow is deep and vast. Drawbacks: except for occasional craters and steep canyons, the land is flat; there are no ski lifts; there is no air; you would weigh one or two pounds, and transportation will cost you billions of dollars. Other than that, science news outlets are advertising it as a great place for snow lovers!

Comety Show: Oceans from Space
October 11, 2011
Finally, a comet has been found with a deuterium-to-hydrogen ratio that is close to that found in Earth’s oceans. That had not been true of many other comets. Astrobiologists claim this ration in Comet Hartley 2 as “proof” that our water came special delivery from water-balloon comets. But why do they believe that, what constitutes proof, and what new problems does the “proof” lead to?

Mercury Messenger: Surprise!
September 30, 2011
As boring as the moon? Just a burned-out cinder? Not Mercury. True to tradition for planetary exploration, the MESSENGER spacecraft has served up a plate of surprises about the innermost planet. In orbit since March, the ship is sending theorists back to the drawing board to figure out a number of puzzling phenomena, some unique to Mercury. Commentators fall into two categories: those that are flabbergasted, and those who say all is well.

It’s Still a Rare Earth
September 25, 2011
Now that hundreds of extrasolar planets are known, how do they compare to ours? The Kepler spacecraft has found a varied assortment of all sizes and distances away from their parent stars. Only a few reside in their star’s habitable zones. But that’s only the first of many requirements for life. Two recent studies indicate that Earth remains a rare bird in the celestial aviary.

Where Do Gems and Precious Metals Come From?
September 7, 2011
Gold, diamonds, and other precious metals and gems... they are found close to the surface of the earth where humans can mine them and make jewelry. But they shouldn’t be there. Heavy elements should have sunk deep into the core of the Earth soon after it was formed. Wait till you hear some of the latest ideas about how precious metals and gems arrived near the surface. Maybe they shot up from the mantle. Maybe they came from outer space.

Another Crash in Lunar Tunes
August 4, 2011
Our moon has two faces. One is the familiar man-in-the-moon side that always faces Earth. The other side is mountainous and heavily cratered, possessing a thicker crust with almost none of the large impact basins we see as dark maria on the Earth-facing side. The giant impact theory for the origin of the moon – that a Mars-size object hit the Earth and the debris coalesced into our planetary companion – has been controversial since it was first proposed. Will adding another impact help? It all depends on what one means by “scientific progress.”

Planetary Eruptions
July 29, 2011
Eruptions can come in two types: literal and figurative. Some planetary bodies are literally erupting. Others are causing figurative eruptions in theories. Here are some recent news stories about planets, moons, comets and other objects circling our sun and other stars. There hasn’t been much news from Mercury or Venus this month, so we’ll start on the home planet and work outward.

Science Can Be Wrong for Decades, Centuries
July 18, 2011
The history of science shows some wrong theories being accepted by leading scholars for long periods of time. Ptolemaic astronomy, unquestioned for over 1200 years, is a prime example. Not all examples are old, though. In modern times as well, scientists are finding that theories unquestioned for decades, even centuries, were wrong. That being so, what confidence can we have that today’s scientific beliefs will stand the test of time for the next decade or century? A recent spate of science articles shows some long-held theories being questioned – others being tossed overboard.

The Rise and Fall of Submerged Landscapes
July 10, 2011
Under the sea lies a lost land of terrestrial life. On this submerged landscape in the North Atlantic Ocean, river channels and fossils of pollen and coal are now being covered up by the remains of sea creatures. Live Science compared it to the lost continent of Atlantis. How did this fossil terrestrial landscape rise above the water, only to sink again?
