Rethinking the history related to indigenous sites in northeast North America
After radiocarbon dating of plant matter, wood and wood charcoal, scientists estimate that the presumed histories of several key indigenous sites in Canada, as relates to first contact with Europeans, are incorrect by about 50 to 100 years. The findings suggest that European trade goods previously used to date individual locations are not in fact good chronological markers and that the history of notable “contact-era” events in northeastern North America during the 15th to early 17th centuries may need to be revaluated.

Burning Incense Is Psychoactive: New Class Of Antidepressants Might Be Right Under Our Noses
Religious leaders have contended for millennia that burning incense is good for the soul. Now, biologists have learned that it is good for our brains too. An international team of scientists, including researchers from Johns Hopkins University and the Hebrew University in Jerusalem, describe how burning frankincense (resin from the Boswellia plant) activates poorly understood ion channels in the brain to alleviate anxiety or depression. This suggests that an entirely new class of depression and anxiety drugs might be right under our noses.

Just a few drinks can change how memories are formed
One of the many challenges with battling alcohol addiction and other substance abuse disorders is the risk of relapse, even after progress toward recovery. Even pesky fruit flies have a hankering for alcohol, and because the molecular signals involved in forming flies’ reward and avoidance memories are much the same as those in humans, they’re a good model for study.
