Dinosaurs Display Death in Watery Grave
February 16, 2012
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
February 11, 2012
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
January 27, 2012
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?
Geologists 750% Wrong in Death Valley
January 23, 2012
A volcanic explosion in northern Death Valley occurred 800 years ago, not 6,000, “far more recently than generally thought,” according to new dating estimates. The event that created Ubehebe Crater is so recent, in fact, geologists think another devastating explosion could happen today.
More Evidence Cambrian Explosion was Un-Darwinian
January 18, 2012
The Cambrian Explosion (the abrupt appearance of animal phyla in the earliest fossil layers bearing multicellular body plans) remains unmuffled. Known by Darwin as a problem for his theory, it has become more problematic to his followers over time. There are now many more Cambrian fossils than Darwin knew of, and they continue the pattern: sudden appearance of complex animals, complete with legs, digestive systems, eyes, and nervous systems. Discoveries of Precambrian fossils have not helped: the ones that are more than microbial appear to be mere colonies of cells with no relationship to animals. Here are more discoveries that fit this pattern.
A Young Moon for Life
January 3, 2012
Our moon is unique in the solar system. Just the right size and just the right distance, it is positioned to stabilize the tilt of Earth’s axis, providing stable seasonal cycles. Science lacks data so far to know just how unique the Earth-moon relationship in a habitable zone is among other stellar systems. We know from the planets of our own solar system that moons come in all sizes, from tiny Deimos to massive Titan, and orbit in apparently arbitrary radii from their host planets. What astrophysicists can do is predict what would happen on earth if things were different. That’s what one scientist did. Another discovery could change the view of the moon’s surface being unaltered for billions of years.
Observations Upset Models of Stellar Evolution
December 22, 2011
Stellar evolution models go back decades. Ever since the Hertzsprung-Russell diagram came out in 1910 (graphing temperature against luminosity), showing most stars fell on a line called the “main sequence”, astrophysicists have sought to understand the life cycle of stars from birth to death. In general, the story goes, collapsing clouds of gas and dust produce main-sequence stars that burn nuclear fuel till they run out. Depending on their masses, they end up as supernovae, red giants or slowly-cooling cinders. While red dwarfs cool down slowly into the darkness, supernovae and red giants eject mass outward into space . Two new planets found close to a red giant are among new headaches for theorists.

Wonders under the sea highlight this roundup of recent geology news. Speaking of seas, the Dead Sea also made headlines, as well as data on the question of whether earthquakes are increasing.
Methuselah Seed Now a Tree
December 4, 2011
The world’s oldest viable seed is now a tree 8 feet tall. The Methuselah palm, discovered in the 1960s as a seed at the Judean fortress of Masada, sprouted in 2005 under controlled conditions. It is the oldest seed verified by radiocarbon dating to be 2,000 years old – from the time the Romans were besieging the mountain fortress built by Herod the Great.
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.
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.
The Blind Men and the Ape Man
October 25, 2011
“We have all seen the canonical parade of apes, each one becoming more human. We know that, as a depiction of evolution, this line-up is tosh. Yet we cling to it. Ideas of what human evolution ought to have been like still colour our debates.” So said Henry Gee, editor of Nature. Are other icons coloring scientists’ views of human origins? How close are they to describing scientifically where we come from?
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.
