Dentistry: Root canal work not so bad after all

Posted: 12 Jul 2019 09:02 AM PDT

Root canal work is not as bad as people think when compared to other dental procedures. Self-reporting of their dental health suggests that patients find the procedure no worse than other dental work which overturns the popular belief that root canal work is the most unpleasant dental treatment.

Early arrival of spring disrupts the mutualism between plants and pollinators

Posted: 12 Jul 2019 09:02 AM PDT

Early snowmelt increases the risk of phenological mismatch, in which the flowering of periodic plants and pollinators fall out of sync, compromising seed production.
