Humans Have Mega-Bites
The design of the human jaw actually makes it 40-50 percent more efficient than for all great apes, Australian researchers have found.
The design of the human jaw actually makes it 40-50 percent more efficient than for all great apes, Australian researchers have found. "Pound for pound we're actually biting harder than a gorilla or a chimpanzee," they say. They also found no big difference between the bite force of a human and that of the "nutcracker man", a fossil hominid, once body size was allowed for. While we have not strongly compromised our ability to crack a hard item or bite off flesh, for better or worse we are less well adapted for hours of chewing tough leaves and bamboo tubers!

- Based on the UN's partition plan for Israel/Palestine, this proposal provides territorial contiguity and sea access to both 'red' and 'blue' America
The definition of a kilogram will now be fixed to Planck's constant, a fundamental part of quantum physics.
- The new definition of a kilogram is based on a physical constant in quantum physics.
- Unlike the current definition of a kilogram, this measurement will never change.
- Scientists also voted to update the definitions of several other measurements in physics.
