Yet healed injuries on either a T-Rex or Triceratops would be a clear sign of a fight. [18] A juvenile T-Rex has a bite force of 5,641 newtons compared to the 35,000 newtons of a full-grown adult.
An exoskeleton “boot” that allows people to walk 9% faster with 17% less effort has been developed by scientists. This robotic footwear comes with a motor that works with calf muscles to give ...
