A hard corn is called a heloma durum, while a soft corn is called a heloma molle. The location of the soft corns tends to differ from that of hard corns. Hard corns occur on dry, flat surfaces of skin. Soft corns (frequently found between adjacent toes) stay moist, keeping the surrounding skin soft. The corn's center is not soft however, but ...

The dramatic elevation gain — which came after the pilot failed to make a turn following takeoff — likely prevented the plane from slamming into the Koʻolau mountain range on the island of ...
In early human fetal development, webbing (syndactyly) of the toes and fingers is normal. At about 6 weeks of gestation, apoptosis takes place due to a protein named sonic hedgehog, also known as SHH, which dissolves the tissue between the fingers and toes, and the webbing disappears. In some fetuses, this process does not occur completely ...
