In the Beginning, Hydrogen: Was It Miller Time?
April 22, 2005
A press release from University of Colorado says that the spark-discharge experiments of Stanley Miller in the 1950s (see 05/02/2003 entry) might be relevant again. Why? Researchers used new models to estimate the amount of hydrogen in the early earth’s atmosphere, and came up with numbers 100 times higher than before. If hydrogen did not […]
Evolutionists Plan Secret Weapon for Kansas Debate
April 21, 2005
Pro-evolution scientists have changed their mind and decided to join the hearings about the Kansas science standards, but haven’t released a list of witnesses. Those in favor of the new standards, which call for critical thinking about evolution, have published a complete list. On March 31, Geoff Brumfiel in Nature1 reported, “Biologists snub […]
How to Get Asteroid Dust Ponds in Mere Millennia
April 19, 2005
A team of U. of Colorado and MIT scientists modeled the formation of the smooth dust ponds found in some of the craters on the asteroid Eros by the NEAR spacecraft (see 02/13/2001 entry). They calculated that micrometeoroid settling from impacts was too slow a process, and instead ran experiments with electrostatic levitation of fine […]
Butterflies Really Know How to Fly
April 18, 2005
The path of a butterfly may appear haphazard to us, but there is a method to the fluttering. A UK team of scientists put transponders on butterflies and monitored their flight paths. They found that the looping paths appear to help with orientation and food detection. The rest of the time, they flew straight at […]
Temple Mount Debris Yields Artifacts from Solomons Temple
April 17, 2005
Israelis were shocked and outraged when Palestinians undertook an illegal construction project in 1999 on the Temple Mount, and threw the debris into the Kidron Valley outside Jerusalem, but there was little they could do about it. Though this “archaeological disaster” caused irreparable damage to the site, the holiest place for the Jews, some Israelis […]
Dinosaur Fossilized in the Act of Laying Eggs
April 15, 2005
Two eggs, with shell material still attached, were found inside the oviducts of a theropod dinosaur, a Chinese team reported in Science.1 This first-time discovery of intact eggs in the body of the female “suggests that theropod dinosaurs had two functional oviducts (like crocodiles) but that each oviduct produced only one egg at a time […]
Gorilla or Hominid? Toumaï Controversy Continues
April 14, 2005
Michel Brunet’s controversial Toumaï skull (Sahelanthropus tchadensis) made the cover of Nature last week,1,2 but rivals contend it was not part of the human line. The skull he found in Chad in 2002 (see 07/11/2002 and 10/09/2002 entries) was badly disfigured and needed reconstructive surgery, leading to criticisms that any interpretations were subjective. […]
Whos Afraid of the Big Bad Academic Bill of Rights?
April 13, 2005
Why would Nature claim that academic freedom is a threat to academic freedom? In the April 7 issue,1 Emma Marris titled her news item, “Professors bristle as states act to mould lecture content – Academics are fighting right-wing ‘bills of rights’.” The academic freedom the professors want is their own freedom to control lecture content, […]
Molecular Motors Do Ballet
April 13, 2005
Scientists at University of Illinois studied dynein and kinesin – the tiny molecular trucks that ferry cargo inside the living cell – and found that they are not just individualists: they cooperate in a delicate yet effective performance. Some scientists had thought that the two machine types, which travel in opposite directions, were […]
Go to the Roach, Thou Robotics Designer
April 13, 2005
Most of us can’t step on them fast enough, but of cockroaches, engineers at Johns Hopkins say “the pesky critters are excellent role models” – for robotics. Classroom exercises include building obstacle courses for cockroaches and observing how they use their antennae to navigate, even in the dark. Said one student, experienced in trying to […]
Solar Eclipse Probabilities Calculated
April 13, 2005
The probability, on average, that the spot you are standing on will see a total solar eclipse is once every 360 to 375 years, says Joe Rao, a lecturer at the Hayden Planetarium, writing for MSNBC News. Some cities, though, like Los Angeles, have to wait 1565.9 years, and some rare spots may not see […]
Bobble-Head Birds See Straight
April 12, 2005
Anyone who has fed pigeons in the park has probably wondered why they bob their heads forward and back when they walk. It not only looks comical to us, it seems like it would give them a very confused sense of sight. Leave it to scientists to go find out why birds bob their heads. […]
Whose Side Is Unenlightened?
April 12, 2005
Here’s an opportunity for readers to compare arguments on both sides of the debate about origins and the nature of science. Donald Kennedy, Editor-in-Chief of Science, wrote an editorial last week that claims the sunrise of the intelligent design movement threatens “twilight for the Enlightenment.”1 He wrote that the “retrogression to the pre-Darwinian zoologist William […]
Astrobiology: Much Ado About Nothing So Far
April 11, 2005
The mood at a NASA Astrobiology Institute conference is very upbeat, according to Leonard David at Space.com, reporting from the meetings in Boulder, Colorado. The participants have set their goals high: Consider it nothing short of the cosmic quest for all time: Understanding the origin, evolution, distribution, and fate of life on Earth and in […]
Variable Constants Dept.
April 11, 2005
Is nothing sacred? EurekAlert reported that the fine structure constant alpha may have changed from its once-thought invariable value, based on new observations from the Keck telescope. “Sacred constant might be changing,” it says. Another study, by contrast, shows no change in the fine structure constant, according to a press release from UC […]

David Coppedge, B.S. Education, B.S. Physics, founded Creation-Evolution Headlines in late 2000 as a way to share science news he was encountering at NASA. It has grown into a highly-trusted source of news and commentary critical of the pro-Darwin consensus, providing analysis of breaking news of interest to creationists and evolutionists, without the Darwin spin. He has authored over 7,000 entries at CEH since its inception.
