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?
Three Strikes Against Uranus
October 9, 2011
Uranus has an axial tilt of 98 degrees, giving it the appearance of a bulls-eye as it revolves around the sun. Its moons revolve comfortably around the planet’s equator. This unusual arrangement, unique in the solar system, has challenged planetary scientists since its discovery. A new model accounts for it through a series of gentle bumps from impacts as the planet was forming from dust and gas, but how would one ever test such an idea?
Human Cloning Advanced Despite Ethics
October 6, 2011
A researcher in New York obtained women’s eggs and conducted experiments on them that could lead to human cloning. While done in the name of regenerative medicine, the experiments on embryonic stem cells involved the destruction of a human embryo. This kind of experimentation raises multiple ethical concerns, but the researcher went ahead anyway, and scientific journals are hailing the advance, albeit with a palpable twinge of conscience about ethics.
Are Aliens Part of Evolution’s Plan, Too?
October 4, 2011
What would the discovery of intelligent aliens mean for Christianity? A recent article made a splash asking that question. Maybe, though, the question should be turned around: what would it mean for evolutionary science?
Science Depends on Ethics
October 1, 2011
Naive reporters and textbook writers sometimes portray science as some kind of neutral, bias-free activity in which the “truth” about nature emerges on its own, as long as the scientist in the lily-white lab coat follows some kind of “scientific method.” Philosophers, theologians, ethicists and scientists with a background in any of these fields know better. One has to believe that truth about nature exists in order to seek for it. And one has to seek for it honestly. Many more examples of science’s ties to ethics or "moral philosophy" can be found, as a few recent articles show.

All biologists agree – creationists and evolutionists alike – that organisms show remarkable adaptations to their environment. They differ only in their explanations for how they got that way. Here are some remarkable examples of adaptation that will challenge any theory of origins.
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.
Evolution Fits Any Data
September 23, 2011
At first blush, it might seem a wonderful thing when many different kinds of evidence can be explained by one simple, elegant theory. Actually, though, too much confirmation can be a theory’s downfall. When a theory explains too much – even opposite things – it really explains nothing. For instance, everything in the universe can be explained by the phrase, “Stuff happens.” Such a theory is useless, even if true. That’s why any theory that explains too much should be looked at askance. Here are some recent observations offered in support of the theory of evolution:
Trouble in Cosmologyland
September 18, 2011
Underneath the veneer of certainty portrayed by TV documentaries about the universe are deep questions and controversies. Some of these briefly appear on publicly-available news stories, only to be covered by new coats of certainty. Are the new veneers fixing the problems or, instead, whitewashing serious weaknesses in current cosmological understanding? Here are some quick looks under the veneer.
Psychotherapy: Needs Reboot? or Just Boot?
September 14, 2011
The word “reboot” assumes a prior boot. You can’t reboot something that never booted up in the first place. The American Psychological Association is calling for “rebooting psychotherapy.” Is it even booted up? The press release begins with an admission that questions whether psychotherapy ever got powered on.
Are Embryonic Stem Cells Obsolete?
September 11, 2011
Adult stem cells can apparently do everything embryonic stem cells can – and they are moving regenerative medicine forward faster, with more results. Since the use of human embryos for research is ethically repugnant to many people, what motivations remain to continue the practice? Here is a rapid-fire list of stem cell news this month:
Science Supports Traditional Values
September 10, 2011
It is well known that liberals outnumber conservatives in academia, but sometimes, scientific studies support traditional values, not leftist ideology. Imagine the surprise of some of these researchers who went looking and found that conservative Christian family organizations have evidence to support their views.
Are Biological Clocks Like Paley’s Watch?
September 9, 2011
What is a clock made of? We think of springs, gears and moving parts made out of metal. But a clock could, in theory, be designed with almost any material. There are water clocks, sundials, and electromagnetic oscillators that all function to tell time. What difference does it make if the parts are made of liquids, laser beams, or plastic? What if a clock was made of biological material—would it be any less a device for keeping time? Would it surprise you that such clocks exist in your body and in every living thing?
Science Without an Object: Astrobiology, Alien Science
September 6, 2011
Can science exist without an observable object? In recent years we have seen serious scientists ponder alternate universes and parallel universes, dark matter, dark energy and other imponderable entities. String theory has yet to rest on observable data, and physicists at CERN are getting worried about not finding the hypothetical Higgs boson. Sooner or later, these theories need to detect their subjects or lose credibility in the science club. Perhaps nowhere else has the disconnect between hype and observation reached the absurd limits of astrobiology and alien science.
A Tale of Two Falsifications of Evolution
September 4, 2011
In diatribes against creationists, evolutionists have long pointed to antibiotic-resistant bacteria as examples of evolution in action. Since antibiotics were unknown before the 1920s, debaters have taunted their creationist opponents with the claim that evolution is such an observable fact, we’re watching it happen right before our very eyes. The force of that argument has been undermined with a new discovery this week that pushes the “evolution” of such resistance way back before human civilization arrived. Another article is claiming that human brain chemistry existed way, way back, “long before animals, brains and even nerve cells existed.”
