<strong>How Squishy Squid Handle Sharp Beaks: </strong>They found that it consists of a changing mix of chitin, water and proteins. When the base is dry, it is about as stiff as the tip. But moisture softens the base up to 100-fold. Advances in tailor-made “functionally graded” materials could allow two different materials to become bonded together by a third, smoothly varying substance, obviating the need of a rivet or an adhesive. <a href="http://www.sciam.com/gallery_directory.cfm?photo_id=06CDA45A-F938-9DE3-0581432855DFFB9A&sc=WR_20080401" target="_blank">>>Link</a>

regrowing limbs

<div class="description"><p>The early responses of tissues at an amputation site are not that different in salamanders and in humans, but eventually human tissues form a scar, whereas the salamander’s reactivate an embryonic development program to build a new limb. Learning to control the human wound environment to trigger salamanderlike healing could make it possible to regenerate large body parts.</p> <p>When the tiny salamander limb is amputated, blood vessels in the remaining stump contract quickly, so bleeding is limited, and a layer of skin cells rapidly covers the surface of the amputation site. During the first few days after injury, this so-called wound epidermis transforms into a layer of signaling cells called the apical epithelial cap (AEC), which is indispensable for successful regeneration. In the meantime, fibroblasts break free from the connective tissue meshwork and migrate across the amputation surface to meet at the center of the wound. There they proliferate to form a blastema—an aggregation of stemlike cells that will serve as progenitors for the new limb. </p></div>
