Amazing Fossils: What Do They Mean?
October 13, 2011
Almost every week, on continents around the world, remains of once-living creatures come to light. Here are just a few of the fascinating fossils that have been reported this month. What do they suggest about life in their day?
Evolutionary Guru Deceives Himself
October 12, 2011
Maybe you’ve had this experience: you’re in class, taking notes, and after a long lecture, the teacher realizes something wrong, and announces, “Forget everything I just said.” Frustrating, isn’t it? That’s what a recent article on evolution did. An evolutionary psychologist explained the origin of lying, then admitted he is self-deceived.
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?
Biomimetics to the Rescue of Science
October 10, 2011
The booming field of biomimetics (imitating nature’s designs) is fascinating not only for the amazing products it promises, but for the fresh new opportunities it provides for science and engineering. From viruses to mammals, everything in the living world is now being seen in a new light: agents of innovation that humans can learn from. Here are just a few examples in recent news, arranged in order from large to small inspirational creatures.
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?
Mighty Mitochondria Conduct Energy Exquisitely
October 7, 2011
None of us could live without mitochondria. These are the power centers ubiquitous in eukaryotic cells. They contain molecular machines in factories whose jobs are to generate and conduct electrical currents. The currents run turbines that packetize the energy in molecules of ATP, which are then used by most processes in the cell. New discoveries continue to fascinate scientists with how mitochondria work. Some scientists use their energy to find ways Darwinian evolution could build the machinery of life.
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.
Lucky LUCA Was Already Complex
October 5, 2011
Simple to complex: that’s been the essence of evolutionary theory ever since Charles Darwin imagined some organic molecules coming together in a warm little pond eons ago. Whatever simple life form emerged from his pond started his evolutionary process that led to the human brain. But what if the “last universal common ancestor” was already highly complex? What if bacteria and archaea are “devolved” remnants of a more complex ancestor? That’s exactly what a new study is claiming.
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?
Of Minds and Men
October 3, 2011
It takes a mind to know one. Can cognizant, sentient minds evolve from slime? Most of the secular science press takes it for granted. Here’s a journey into storybook land, where imaginative reporters see visions of slime climbing out of the mud to look back at an unobservable history of matter becoming mind.
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.
Mercury Messenger: Surprise!
September 30, 2011
As boring as the moon? Just a burned-out cinder? Not Mercury. True to tradition for planetary exploration, the MESSENGER spacecraft has served up a plate of surprises about the innermost planet. In orbit since March, the ship is sending theorists back to the drawing board to figure out a number of puzzling phenomena, some unique to Mercury. Commentators fall into two categories: those that are flabbergasted, and those who say all is well.
Enjoy Your Body Gifts
September 29, 2011
When you eat right and exercise to do your body good, you may have little idea how much your body is giving back all the time. From recent scientific discoveries, here’s a look at a few mechanisms under our skin that not only keep us alive, but provide us with a shopping mall of good things.
September 26, 2011
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.
