Dark Energy: Can a Theoretical Entity Be Measured?

The redshift of galaxies has been measured for some 90 years, but the existence of “dark energy” was postulated only recently – in the late 1990s.  It was needed to explain unexpected dimness of the most distant galaxies, as measured by Type Ia supernovae.  Some cosmologists claim they are measuring dark energy – others say […]

Darwin Caught Out of Bounds

What business does Darwin have in quantum mechanics or engineering?  Wasn’t his a theory on the origin of species – that is, plants, animals and living things?  Some scientists seem intent on extrapolating his views to all of reality, including areas commonly thought to be in the domain of intelligent design.  Let’s get physical:  An […]

Are Saturn’s Rings Evolving?

Can ring particles grow into moons? And is that how planets grew from rings around stars?

Your Inner Locomotive Revealed

Visualize an old locomotive train roaring down the tracks.  One of the characteristic images that surely comes to mind is the oscillating motion of the coupling rods on the wheels.  The long rods that connected the wheels provided a way to convert heat energy from the steam into mechanical energy (example video on YouTube).  It […]

Breaking Up an Ice Age Is Hard to Do

“Ice Age 3” the movie is out, and the subject of ice ages deserves some attention.  Atmospheric scientists and geologists seem very confident sometimes about things they know about only indirectly, like ice ages.  At other times, though, the rhetoric turns diffident (opposite of confident).  Take this opening paragraph from PhysOrg: Scientists still puzzle over […]

Secular Geology Admits to Rapid Canyon Formation by Megafloods

It’s hard to deny catastrophic canyon formation when you have the evidence right in front of you.  Look what happened in Texas a few years ago, as reported by PhysOrg: In the summer of 2002, a week of heavy rains in Central Texas caused Canyon Lake – the reservoir of the Canyon Dam – to […]

How Well Do We Know What Stuff Is Made Of?

When we think of the “hard sciences,” physics usually tops the list.  A closer look at what physicists think the universe is made of, though, hardly makes the science look hard.  Look at this headline on PhysOrg, for instance: “Study finds there may be multiple ‘God particles’”.  The title refers, of course, to the famed […]

Butterfly Wing Shimmer Done With 3-D Crystals

Those shimmering flashes of light seen on butterfly wings are not done with pigments.  They’re done with tiny, geometric crystals called gyroids stacked in 3-D patterns, scientists have found.  They are so effective at concentrating color, the scientists want to imitate the trick.     “A precise characterization of color-producing biological nanostructures is critical to […]

Flagellum Replaces Parts on the Fly

A new study appears to show that the bacterial flagellum, a molecular rotary motor that has become iconic of the intelligent design movement, can repair parts of its rotor while it is rotating.  The results of the study by Oxford University were published in PNAS,1 and were also the focus of a Commentary in PNAS […]

Jupiter Scores Another Hit

Amateurs saw Jupiter get struck by something again on June 3.  Last year, an asteroid also hit the giant planet.  Good thing Jupiter caught it and not Earth.  The asteroid, believed to be about 500 meters across, left a scar as big across as the Pacific Ocean.  National Geographic and the BBC News have photos […]

Your Nerves and Heart Depend on Cellular Pulleys, Latches and Switches

Biologists continue to peer closer and closer at cellular machines that work just like man-made ones, only at scales so tiny, they control individual atoms.  Of particular interest have been the gates in the membranes of cells that allow certain atoms in but keep others out.  A recent paper in Cell by an Australian team […]

Science Explains Why the Universe Exists

They’ve done it again – those clever scientists have figured out why the universe exists.  What would we ever do without them?  Michael Bolen at Yahoo News had to share the good news, “Scientists discover explanation for why the Universe exists.”  Space.com explained it as a victory in an ancient contest: “Why We Exist: Matter […]

How Science Is Done: Upsetting Applecarts

Hardly a week goes by without some scientific finding upsetting an applecart – a long-held belief.  Often, those beliefs are scientific theories taught in textbooks by science professors.  Defenders of science say that this is the way science works.  It’s a self-correcting process, they argue; it’s to be expected that new data will lead to […]

Bacteria: Let’s Harness Those “Perfect Machines”

Ten Italian scientists have a novel idea.  They want to hitch up their wagons to bacteria and use them to power nanomachines.  It’s too much work to build such “perfect machines” from scratch, they said.  Why not just take advantage of what nature has already provided?     Their paper in PNAS1 is downright dreamy […]

Can Darwin Be Rescued from a New Eye Discovery?

Darwinists have claimed for years that the human eye is an example of bad design, because it is wired backwards – the photoreceptors are located behind a tangle of blood vessels and other material.  But then in 2007, German scientists found that cone-shaped cells called Müller cells act like waveguides that transmit the light through […]
