News from various sources
INSPIRED BY SUCKERS
Science News (9th April 2018), reported that researchers have constructed a robot inspired by an octopus’s suckers (left). It “uses a pair of suction cups to scoot around vertical surfaces. The bot can clamber across rough and smooth terrain, above ground and underwater, carrying up to five times its own weight.” It is hoped similar robots could “help conduct surveillance or inspect buildings and bridges.”
COMMENT: Even the simplest robots need designers and engineers before they can be used. The octopus, on which these new robots’ design is based, must have had a Designer too!
THE WONDER OF EGGS
Science Daily (30th March 2018) posed the question: “How is it that fertilized chicken eggs manage to resist fracture from the outside, while at the same time, are weak enough to break from the inside during chick hatching?” The answer given was: “It's all in the eggshell's nanostructure.” It was claimed that “Birds have benefited from millions of years of evolution to make the perfect eggshell, a thin, protective biomineralized chamber for embryonic growth that contains all the nutrients required for the growth of a baby chick.”The shell of an egg is porous, allowing the developing chick to breathe. As it develops it takes calcium from the inside of the shell, strengthening its bones, while at the same time the shell becomes thinner, ready for the chick to break through the shell, using a special “egg tooth” — which falls off soon after hatching. In a special BBC-TV programme “The Wonder of Eggs” (31st March 2018), well-known TV presenter and naturalist David Attenborough described an egg as “a miracle of nature” and “Nature’s most perfect life support system.”
COMMENT: If “millions of years of evolution” were needed to “make the perfect eggshell” how would birds have survived in the meantime? The same applies to the “egg-tooth”, without which the chick would be trapped inside the egg. Like so many other things in the natural world, it all had to be right the first time. Trial and error would never have worked!
Science News (22nd March 2018) reported that earwigs have wings (left), but rarely use them. “Because earwigs spend most of their time underground and only occasionally take to the air, they pack their wings into packages with a surface area more than 10 times smaller than when unfurled, using an origami-like series of folds. Springy wing joints let the insects bypass some of the mathematical constraints that normally limit the way a rigid two-dimensional material can be folded.” Mechanical engineer Andres Arrieta said, “Earwig wings’ folding pattern should be impossible according to mathematical equations that predict the three-dimensional designs that can be made by folding a two-dimensional material like a sheet of paper.”
COMMENT: So these humble insects achieve the impossible! Once again, scientists express surprise at one of the wonders of God’s creation, which defies their understanding of mathematics.
NON-EVOLUTION OF MOTH COLOURS
According to Science News (11th April 2018), “Tiny light-scattering structures that give today’s butterflies and moths their brilliant hues date back to the days of the dinosaurs.” This conclusion comes from a detailed examination of fossils from the “Jurassic Period” supposedly 200 million years ago, which revealed that microscopic texturing on the scales of fossil moths resemble what’s seen today in Micropterix aruncella (above).
COMMENT: This discovery strongly suggests that these moths have always had the same wing colours, so no evolution has occurred. We also would dispute the dating. Could such intricate details really be preserved for such a length of time?
THE ‘RAILWAY’ IN YOUR CELLS
“Almost every cell in our bodies contains a 'railway' network, a system of tiny tracks called microtubules that link important destinations inside the cell” reported Science Daily (12th March 2018). The tracks are just a millionth of a millimetre across! Cell biologist Professor Robert Cross said: “The railway is just as crucial to a well-run cell as a full-size railway is to a well-run country. “
COMMENT: Was a railway network ever built through random, chance processes? The words of the Psalmist come to mind: “I am fearfully and wonderfully made.” (Psalm 139: 14).
INSPIRED BY DRAGONFLIES
Science Daily (25th April 2018) reported: “A team of international scientists have created a new form of highly-efficient, low-cost insulation based on the wings of a dragonfly. The material, known as an aerogel, is the most porous material known to man and ultralight, with a piece the size of a family car weighing less than a kilogram.” Despite taking up less than 2% of the insect's total body weight it is strong enough to carry the insect thousands of miles. Scientists at Newcastle University plan to use this design to make insulation panels for buildings and cars.
COMMENT: Using their intelligence scientists plan to copy this design, which must have been designed by a higher intelligence!
