Parasitism is bad. Parasitism is evil. Parasites wage war against innocent hosts. This is our mindset. What if parasites can do good? This change of heart seems to be happening for one case, the case of transposable genetic elements. If they are only doing harm to the host, why did some biologists find that “positive selection” seems to be maintaining them? That makes it sound like the cells need them.
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?
Oozing Life Up Against All Odds
January 20, 2012
The origin of life clearly requires a major leap in complexity, but not just any complexity. A conglomerate rock is complex, but not alive. Life has functional complexity – the ability to selectively take in materials to grow, move and reproduce. Life also requires growth, but not just any growth. Fire grows and reproduces, but is not alive, whereas a living cell grows and reproduces according to internal programmed instructions. Evolutionists think the origin of life by natural causes is a tractable problem that will eventually be solved. Let’s see a couple of examples of how their work is coming along.
Liberal Bias Detected in Science Media
January 19, 2012
Incredible as it sounds, the science news media seem to have a liberal bias. This is astonishing, considering the vast majority of science professors in academia are Democrats. The following examples illustrate this trend that came to light around 1859.
More Upsets for Darwin
January 17, 2012
For every hyped-up demonstration of evolution in action the media announces with gusto, there are setbacks that often do not get the splashy headlines. Here are three recent examples.
Selling Darwinism as a Cinch
January 16, 2012
The origin of biological complexity is a major concern for believers in unguided, random processes of nature. Some recent news articles, though, make it sound easy – no problem at all. But do their theories and experiments reflect the real world?
SETI Finds Intelligent Humans
January 15, 2012
The Search for Extra-Terrestrial Intelligence (SETI) is 50 years old this year. SETI’s latest scientific discovery was the detection of a human-made satellite in Earth orbit. In a sense, this counts as a success: the detection of a signal of intelligent origin from an extra-terrestrial source (beyond terra firma). The false alarm helped calibrate the instrumentation, but did little to garner support for the effort to find aliens. The SETI Institute was all SETI-ready to party hardy at the 50th anniversary of Frank Drake’s first search, but instead, found itself struggling to keep its doors open after a severe shortfall of private funds, highlighting questions about the scientific status of the long-shot project.
Science Grab Bag
January 13, 2012
Here's a random assortment of things floating around in the science news media – some fascinating, some informative, some disgusting. We’ll let the readers decide which is which. Since it’s Friday the 13th, a day to enjoy like any other day, we’ll give you a baker’s dozen to sample.
Tilt-A-World: Another Constraint on Habitability
January 12, 2012
Did you ever ride a Tilt-A-Whirl, one of those cheap carnival rides that makes you dizzy and sick? Our planet would be like that if its inclination were out of control. Without tilt stability, a new study reveals, we wouldn't be sick, we'd be dead, or never alive in the first place. It's not enough to be in the Habitable Zone. Would-be inhabited planets need to avoid a new problem, called “tilt erosion.”
Cosmologists Forced to “In the Beginning”
January 11, 2012
The late astronomer Robert Jastrow detailed in his 1978 book God and the Astronomers how cosmologists were repulsed by the idea the universe had a beginning. He found it quizzical that they would have such an emotional reaction. They all realized that a beginning out of nothing was implausible without a Creator. Since then, various models allowing for an eternal universe brought secular cosmologists relief from their emotional pains. It now appears that relief was premature.
What Do Scientists Know About Prehistory?
January 9, 2012
Evolutionary biologists and geologists speak of events happening millions or billions of years ago as concrete facts. They are not observational facts, though; they are inferences from indirect evidence. Indirect evidence can often lead to different conclusions; in fact, some philosophers like Duhem and Quine argue for “under-determination of theory by data,” meaning that data can never converge to support just one theory. Some can demonstrate logically that there are an infinite number of theories that can explain a set of data. Evolutionary scientists counter that there are only one or a few that are reasonable (implying that theirs is among the limited set of reasonable ones). Recent discoveries that threaten to overturn past reasonable theories, though, cast doubt on their confidence.
Loving Dark Matter Rather Than Light
December 31, 2011
There are two ways to describe dark things in science. One is phenomena we know exist, even if invisible to us, because we can measure their effects with instruments (X-rays, infrared radiation). The other is darkness as a placeholder for something not yet explained. Cosmologists have been talking about “dark matter” for decades now, and “dark energy” since the 1990s. Which category of dark ideas are they? Whether scientifically valid phenomena or placeholders for ignorance, one thing is clear from recent articles: much more knowledge is needed.
Chinks in the Scientific Method
December 29, 2011
V & V. That’s shorthand in project design for “validation and verification.” Does the scientific method provide V & V? We are all taught to think that peer review, publication and replication help science to be self-checking, so as to avoid error. Some recent articles show that ain’t necessarily so. It may sound good in theory, but in practice, the ideal doesn’t always match the real.
December 25, 2011
Could any “useless” natural object composed of simple materials exceed the beauty of a snow crystal? As you wish for a white Christmas, think about two snowflake designers: one who makes them in a lab, and one who makes them in clouds.
Naturalizing Miracles, or Miracle-izing Nature?
December 24, 2011
Certain scientists feel a need to explain all phenomena by means of natural processes, including reports of miracles. The word “natural,” however, is slippery, taking on a variety of meanings. Is scientific reasoning, for instance, natural? If so, it is not composed of atoms and forces acting according to “natural law.” Is it possible that the tables can be turned on the naturalizers, to rescue Christmas from materialist re-interpretation?
