This week, Stu shares new research that may explain why the most famous dinosaur, the T. rex, evolved such big heads, plus maybe why they had tiny arms as well; and Chris talks about reverse or anti lasers, which absorb light rather than emit it, and for that to make that sense he tries to explain how regular lasers work too.
