Drug-resistant bacteria are one of humanity’s great emerging threats. Microbes resistant to most or all antibiotics – superbugs, they’re called – just laugh at whatever we throw at them. In the search for new antibiotics, a group of researchers at McMaster University have turned over an interesting stone — cannabis.
I met Vivien Sansour for the first time back in 2016, in her home town of Beit Jala, on the southern edge of Bethlehem, in Israeli-occupied Palestine. An anthropologist by training, Vivien has turned to the promotion of food and the cultural sovereignty tied to growing one’s own and saving the seeds, as her life’s work.
In a hyper-polarized world where everyone disagrees about everything and even the most straightforward affairs seem uncertain, an eminently erudite, well-traveled and literate critic is liable to draw a large crowd. Robert Fisk, dean of Middle East journalism, is one such man.
Earth’s oceans are warming at a remarkable rate. Over ninety percent of the atmospheric heat humans have generated in the course of the past decades has been absorbed by Earth’s oceans.

Earth’s cryosphere plays a huge role in regulating climate. As our planet warms, its cryosphere is slowly melting, triggering positive feedbacks that make earth scientists worry.
