Desert locusts' jaws sharpen themselves, materials scientist discovers
Sharks lose teeth all their lives, replacing them in a kind of endless rotating Rolodex, while humans, of course, get only our two sets. Beavers' teeth, notoriously, grow all their lives and have to be worn down to prevent ...

The origin of the sun's magnetic field could lie close to its surface
The sun's surface is a brilliant display of sunspots and flares driven by the solar magnetic field, which is internally generated through a process called dynamo action. Astrophysicists have assumed that the sun's field is ...
