This week in the sciosphere:

- Chal­lenging the def­i­n­i­tion of “cancer”

- Just because they’re amazing, a view of the cenotes in the Yucatan

- The last year of this Inca girl’s life may have been the best, it was cer­tainly the most nutritious

- Wow, that’s a big, smelly flower…everyone said it stank, except this lady? A bit on the chem­istry behind that stench.
