Age Estimate for Oldest Glacier Revised Way Down

February 2, 2005

Deposits from Antarctic glacial ice thought to be 8.1 million years old have been re-dated at not more than 310,000 years old, and maybe as little as 43,000, reports a team writing in the Feb. issue of Geology.1 Ng (MIT), Hallet, Sletten and Stone (U. of Washington) analyzed cosmogenic helium-3 and calculated the rate of […]

Shroud of Turin Debate Reopens

January 26, 2005

The shroud was from the 13th century, concluded earlier researchers, using carbon 14 dating methods. Now, other experts are claiming the methods were flawed, because the researchers dated a mended patch made by medieval monks. The BBC News reports a new claim that it is older than thought: between 1300 and 3000 years old. National […]

How To Make Instant Petrified Wood

January 24, 2005

“Want to petrify wood without waiting a few million years? Try this,” EurekAlert teases. The recipe: pick up some pine or poplar wood chips from your local lumber store, soak them in an acid bath for two days, then soak them in silica solution for two more. Air dry, then put into argon-filled furnace at […]

Flying Saucer Lands on Titan

January 15, 2005

The Huygens Probe successfully landed on the surface of Titan Friday morning, and appears to have remained active for an hour after impact. See the official European Space Agency site for latest scientific results. Download this 27-page Mission Description from JPL (2.0mb) for a detailed plan of the now highly successful mission. At […]

We Were Wrong About Isochrons, Geologists Say

January 12, 2005

An isochron (a word meaning “equal time”) is supposed to be a line connecting points on a graph that represent the same age, or the same age difference. If your rain gutter barrel fills fast and the bucket in your garage fills slowly, for instance, you can figure the time the rain started if you […]

Galaxy Evolution Explorer Finds Living Fossils

December 21, 2004

Some galaxies are 10 times brighter in ultraviolet than others, and are thought to be “young” galaxies undergoing violent star formation with frequent supernova explosions. In theory, they populated the early universe but should have quieted down by now. The Galaxy Evolution Explorer, an ultraviolet wide-field orbiting telescope, launched April 2003, has just made a […]

Late Bloomer Galaxy Just Now Getting Into Star Formation?

December 15, 2004

According to a story in New Scientist, a “young” galaxy is just now starting its process of star formation. Most galaxies formed more than 10 billion years ago. Those born later tend to be fashioned from recycled gas rich in metals that were forged by previous generations of stars. But astronomers Trinh Thuan of the […]

Planet-Building a Mess, or Theories a Mess?

October 18, 2004

A news release from the Spitzer Space Telescope operated by JPL says, “Astronomers Discover Planet Building is Big Mess.” Data from the orbiting infrared observatory indicates that dust disks around stars appear to be dominated by collisions of large bodies. Surprisingly, the dust disks do not correlate with the stars’ ages. A study of 266 […]

News Nuggets

October 12, 2004

Here’s a collection of news items that deserve quick notice: Mars Rumbles: Mars still has minor earthquakes, says Space.com, That’s without plate tectonics, “But scientists don’t know exactly how Mars is constructed.” The Mars Exploration Rovers, meanwhile, awaking from a winter’s nap, are still gathering science data long past their expected lifetime. Evidence for past […]

How Are Radioactive Dates Determined?

October 6, 2004

To most of us, the practice of radioactive dating seems like a highly-technical, incomprehensible skill that nevertheless (we are told) yields absolute ages of things. We don’t know exactly how they arrive at the results, but are led to trust them because very smart people get their answers using hard science with extremely accurate equipment. […]

Dating of Crater Rays Needs Overhaul

October 4, 2004

A dating method relied on by planetary geologists needs drastic revision, according to Planetary Science Research Discoveries (PSRD) scientists at the University of Hawaii. Crater rays are the streaks that extend radially from impact craters. Previously, planetary scientists assumed they darken over time under bombardment from the solar wind and can be used as indicators […]

Date of Biblical Artifact Corroborated

September 29, 2004

In 1979, a silver scroll was discovered near Jerusalem that contained the text of the priestly benediction known from the Pentateuch (Numbers 6:24-26). The scroll was dated at the 7th century BC at the time, but doubts remained, some thinking that instead it was from post-exilic times centuries later. Now, according to a New York […]

Human Common Ancestor Lived 3500 Years Ago

September 29, 2004

Nature Science Update reported on a surprising find by Joseph Change (Yale) and Douglas Rohde (MIT). They claim, based on computer modeling of human breeding and migration, that we are all related to the same common ancestor, not millions, but just thousands of years ago, possibly just 1500 BC in Asia, and that perhaps a […]

Land Dinosaurs Buried with Fish

August 22, 2004

Since dinosaurs are icons of evolutionary TV shows and even children’s cartoons about prehistoric evolving life, it may come as a surprise to some that evolutionists do not own the dinosaurs; even the name dinosaur was invented by a creationist, Richard Owen. Last month, a creationist dinosaur dig in Montana1 was a monstrous success. Joe […]

British Cave Art Wins Admiration

August 18, 2004

The British are overtaking the French in the ancient cave art competition; National Geographic News reports that “English caves may hold the most elaborate Ice Age cave-art ceiling ever discovered.” Thought to be 12,000 to 13,000 years old based on radiocarbon results and “stylistic comparison.” There was some surprise that the art could have survived […]
