The tumor’s able to sync up with the circadian clock and work its own growth into the natural daily processes of the body. These findings reveal why certain drugs affect brain tumors differently.

Why we should be wary of dirt.

Antibiotic resistance is estimated to only get worse in the coming years – taking away many of our options for effective medication. New research in Nature Communications shows that bacteria in soil may be aiding this scary future. Pollution and changing land use can disturb this ecosystem and make it easier for the resistant bacteria in dirt to infect humans.

Researchers used imagery rehearsal therapy to replace nightmare imagery with less frightening scenes. The participants reported lower levels of anxiety, nightmare distress, and nightmare effects by the end of the study. The research is published in the journal Dreaming.
