Experts at the Australian National University (ANU) have recently compiled a new mathematical model, that goes a long way towards explaining the physics behind the pruney fingers we get if we stay in the water for prolonged periods of time. Evolutionary biologists say that this is an evolutionary adaptation we develo... |

Investigators say that they are currently seeing an amazingly-high rate of beak deformities in wild bird species. They add that no clear cause for this has yet been discovered, and reveal that one possible culprit could be the extensive damage the birds' habitats are suffering today.

The oldest known textiles are some sail pieces, made 7,000 years ago. The first textile fibers used by humans were flax and wool, but today a large array of natural and synthetic fibers are employed. The sheep wool is made of keratin, the same protein found in the nails, horns, feathers, reptilian scales and the uppe... |

The hair fiber has in its composition keratin and some derived proteins. The protein has a fibrous structure, which also enters in the composition of feathers, nails, hoofs, and horns. Of all the hair growing on the human body, the beard has the toughest and most resistant fibers, being as hard to cut off like copper... |

The problem of the plastic contamination could be solved by biodegradable polymers made of poultry feathers, a solution that would also decrease costs in poultry industry. Only in the US over 29 million tons of non-biodegradable plastic waste reach the landfills yearly. "12 % of all plastic packaging ends up in landf... |
