Gecko Stickability!

Story from 'Creation' magazine No. 26 No 1 2004, 'Beyond the limits of human technology' by Jonathan Sarfati B.Sc.(Hons), Ph.D., F.M.
'Dr. Andre Geim, of the University of Manchester, leading a team of scientists from the UK and Russia, prepared a self-cleaning adhesive tape modelled on the gecko's foot. Their tape, with a contact area of only 0.5 cm with a contact area of only 0.5 cm with glass, could bear a load of more than 100 grams. However, the tape is not durable enough to attach and detach more than a few times, unlike the real gecko. The researchers proposed using a more durable material - that which the real ones are made of, keratin.
If they did, then gloves and shoes made of this might enable a real spiderman (or should that be geckoman?) to climb up walls of almost any surface.
'Geckos can stick to almost any surface, so it can even run upside down on a ceiling of polished glass. This is due to the way tiny chemical forces are exploited by tiny hairs called setae, about 1 10th of a millimetre long and packed 5,000 per square millimetre. The end of each seta has about 400-1000 branches ending in a spatula-like structure....This is an amazingly fine structure that the researchers said was 'beyond the limits of human technology'.'

Glyconutrients are also amazing plant-sourced supplements produced by Mannatech and founder Sam Caster. These glyconutrients are essential for optimal health and wellness overcoming the insecticides, pollutants and green harvest etc. Glyconutrients are mostly missing from our diets.

Arthrodpd Fossilized in a Flash!

Taken from 'Creation' magazine Vol. 27 No. 2 2005 by D. Catchpoole, B.Ag.Sc.(Hons.) Ph.D.
Have you ever seen an arthropod (e.g. lobster, scorpion, cockroach) shedding its 'skin'?
You've got to be in the right place at exactly the right time - it's all over in minutes. So you can imagine paleontologists' excitement on finding this fossil of the arthropod Marrella splendens, fossilized at the exact moment of moulting! (Garcia-Bellido, D.C. and Collins, D.H., Moulting arthropod caught in the act, Nature 429(6987):40, 2004)
'It's basically an astounding specimen', said paleontologist Derek Briggs of Yale University.
'The likelihood of capturing such an event is so astronomically small', said Desmond Collins, a senior scientist at the Royal Ontario Museum in Canada, .... 'The discovery of an arthropod in the act of moulting was exciting because it was so unexpected.'
Until now, only moulted skins had been found in the fossil record .........
Another reason this find is important, said Dr. Collins, is that it confirms what paleontologists had suspected; namely, that early arthropods moulted during growth, just as they do today.'

Luckily we don't have to shed our skins so quickly. Glyconutrients produced by Mannatech and founder Sam Caster, uses plant extracts to enhance cell-to-cell communication and overall physical health. Glyconutrients are necessary in every cell in your body but are mostly missing in the modern diet.
