This remarkable case occurred in 2013 in Fuzhou, Fujian province, China, involving a 22-year-old man named Xiaolian. After a car accident in August 2012, Xiaolian did not receive timely treatment, resulting in a severe infection that destroyed his nasal cartilage, making standard reconstruction impossible.

Surgeons at Fujian Medical University Union Hospital employed a pioneering tissue engineering technique to grow a new nose. Surgeons took cartilage from Xiaolian's ribs to sculpt a new nasal scaffold. They inserted this scaffold under the skin of his forehead. The forehead was chosen because of its rich blood supply, which allows the tissue to remain alive and develop, and because its skin texture closely matches that of a nose.

A tissue expander (a type of balloon) was used under the forehead skin to stretch it and create the necessary space for the new structure. Over roughly nine months, the new nose was nurtured by the forehead's blood vessels, developing into a fully shaped, living organ.

Once the new nose was mature and healthy, surgeons planned to move it from the forehead to the center of his face, rotating it while keeping it attached to the blood supply, and finally separating it once it established new blood vessels in the new position.🥀

There’s more to spiders than most people realize.

A recent study from the University of Massachusetts Amherst found that nearly 90% of insect and arachnid species in North America have no conservation status, meaning scientists don’t know how they’re doing. Researchers say this gap leaves many species unmonitored and unprotected.

Experts say spiders and insects play key roles in ecosystems, from pollination to controlling pests. Without better tracking and protection, scientists warn their decline could have wider impacts on the environment.

Did you know that grasshopper use belly to hear instead of ear?

In grasshopper, the membrane that vibrate in response to sound are located on their first abdominal segment, which is found under the wings.the eardrum is called tympanal organ ( tympanic membrane in some organisms)
